Welcome
In most cities and counties, permits will be required for the installation of electrical circuits or the construction of exterior
surfaces (decks and gazebos). In addition, some communities have adopted residential barrier codes which may require
fencing and/or self-closing gates on the property to prevent unsupervised access to a pool (or hot tub) by children under 5
years of age. Your Limelight hot tub is equipped with a locking cover that meets the ASTM F1346-91 Standard for Safety
Covers and as a result, is usually exempt from most barrier requirements. As a general practice, your local Building
Department will inform you of any applicable barrier requirements at the time a permit is obtained for the installation of an
electrical circuit. Your Limelight dealer can provide information on which permits may be required.
Watkins®Manufacturing Corporation
congratulates you on your decision to enjoy
the finest hot tub available... Welcome to the
growing family of LimelightTM hot tub owners.

SAFETY INFORMATION
IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
AVOIDING THE RISK TO CHILDREN
DANGER:
•RISK OF CHILD DROWNING. Extreme caution must be exercised to prevent unauthorized access by children. To avoid accidents,
ensure that children cannot use a hot tub unless they are supervised at all times.
WARNING:
• To reduce the risk of injury, do not permit children to use this hot tub unless they are closely supervised at all times.
• To reduce the risk of injury, lower water temperatures are recommended for young children. Children are especially sensitive to hot water.
DO:
• Make sure you always lock the child resistant locks after using the hot tub for your children’s safety. Every LimelightTM hot tub is equipped
with a locking cover that meets the ASTM F1346-91 Standard for Safety Covers.
• Test the water temperature with your hand before allowing your children to enter the hot tub to be sure that it’s comfortable. Children are
especially sensitive to hot water.
• Remind children that wet surfaces can be very slippery. Make sure that children are careful when entering or exiting the hot tub.
DON’T:
• Allow children to climb onto the hot tub cover.
• Allow children to have unsupervised access to the hot tub.
AVOIDING THE RISK OF ELECTROCUTION
Risk of electrocution
• Connect only to a grounded source.
• Do not bury the power cord. A buried power cord may result in death, or serious personal injury due to electrocution if direct burial-type
cable is not used, or if improper digging occurs.
• A ground terminal (pressure wire connector) is provided on the control box inside the unit to permit connection of a minimum No. 10 AWG
(6 mm2) solid copper bonding conductor between this point and any metal equipment, metal water pipe, metal enclosures of electrical
equipment, or conduit within five feet (1.5 m) of the unit as needed to comply with local requirements.
• Do not operate the audio main controls while inside the spa (if spa is equipped with an audio component).
• Do not connect any auxiliary components (for example, cable additional speakers, headphones, additional audio components) to the
audio system unless approved by Watkins Manufacturing Corporation .
• Do not self service audio component by opening or removing cover as this may expose dangerous voltage or other risk of injury. Refer all
servicing to qualified service personnel.
• Do not attach an external antennae to a spa audio system unless installed by a licensed electrician in accordance with Article 810 of the
National Electric Code, ANSI/NFPA 70.
WARNING:
• To reduce the risk of electrical shock, replace a damaged cord immediately. Failure to do so may result in death or serious personal injury
due to electrocution.
230 volt, permanently installed
• A ground terminal is provided on the terminal block (TB-1, system ground terminal) located inside the control box. To reduce the risk of
electric shock, connect this terminal to the grounding terminal of your electrical service or supply panel with a continuous green, insulated
copper wire. The wire must be equivalent in size to the circuit conductors supplying the equipment. In addition, a bonding terminal
(pressure wire connector) is provided on the outside of the control box for bonding to local ground points. To reduce the risk of electric
shock, this connector should be bonded with a No. 10 AWG (6 mm2) solid copper wire to any metal ladders, water pipes, or other metal
within 5 feet (1.5 m) of the hot tub to comply with local requirements. The means of disconnection must be readily accessible, but must be
installed at least 5 feet (1.5 m) from the hot tub.
• Your hot tub is provided with a suitably rated circuit breaker to open all ungrounded supply conductors.

Page 2
Page 2
Safety Information
• Your hot tub uses ground fault circuit interrupters in the electrical subpanel. Before each use of the hot tub and with the unit operating,
push the TEST button on each breaker. The switch should click over to the “Trip” position. Wait 30 seconds and reset each GFCI breaker
by switching it completely off and then completely on. The switch should then stay on. If either of the interrupters does not perform in this
manner, it is an indication of an electrical malfunction and the possibility of an electric shock. Disconnect the power until the fault has
been identified and corrected.
NOTE: Failure to wait 30 seconds before resetting the GFCI may cause the hot tub’s Power Indicator (on the control panel) to blink. If this
occurs, repeat the GFCI test procedure.
DANGER: RISK OF ELECTRICAL SHOCK
• Install at least 5 feet (1.5 m) from all metal surfaces. A hot tub may be installed within 5 feet of a metal surface if each metal surface is
permanently connected by a minimum No. 10 AWG (6 mm2) solid copper conductor attached to the wire ground connector on the
terminal box that is provided for this purpose if in accordance with National Electrical Code ANSI/NMFPA70-1993.
• Do not permit any electrical appliances, such as a light, telephone, radio, or television within 5 feet (1.5 m) of a hot tub. Failure to maintain
a safe distance may result in death, or serious personal injury due to electrocution if the appliance should fall into the hot tub.
• Install your hot tub in such a way that drainage is away from the electrical compartment and from all electrical components.
DO:
• Be sure your hot tub is connected to the power supply correctly - use a licensed contractor.
• Disconnect the hot tub from the power supply before draining the hot tub or servicing the electrical components.
• Test the Ground Fault Circuit Interrupter(s) before each use.
• Replace audio components only with identical components (if your spa is equipped with an audio component).
• Install your hot tub in such a way that drainage is away from the electrical compartment and from all electrical components.
DON’T:
• Use the hot tub with the equipment compartment door removed.
• Place electrical appliances within 5 feet (1.5m) of the hot tub.
• Use an extension cord to connect the hot tub to its power source. The cord may not be properly grounded and the connection is a shock
hazard. An extension cord may cause a voltage drop, which will cause overheating of the jet pump motor and motor damage.
• Attempt to open the electrical control box. There are no user serviceable parts inside.
RISKS TO AVOID
DANGER: RISK OF INJURY
• To reduce the risk of injury to persons, DO NOT remove suction fittings or filter standpipe (located in the filter compartment).
• The suction fittings in the hot tub are sized to match the specific water flow created by the pump. Never replace a suction fitting with one
rated less than the flow rate marked on the original suction fitting.
• There is a danger of slipping and falling. Remember that wet surfaces can be very slippery. Take care when entering or exiting the hot tub.
• Never operate hot tub if the suction fittings are broken or missing.
• People with infectious diseases should not use the hot tub.
• Keep any loose articles of clothing, long hair or hanging jewelry away from rotating jets or other moving components.
Increased side effects of medication
• The use of drugs, alcohol, or medication before or during hot tub use may lead to unconsciousness with the possibility of drowning.
• Persons using medications should consult a physician before using a hot tub; some medication may cause a user to become drowsy,
while other medication may affect heart rate, blood pressure, and circulation.
• Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants should not use the hot tub.
Health problems affected by hot tub use
• Pregnant women should consult a physician before using hot tub.
• Persons suffering from obesity, or with a medical history of heart disease, low or high blood pressure, circulatory system problems, or
diabetes should consult a physician before using hot tub.
Unclean water
• Keep the water clean and sanitized with correct chemical care. The recommended levels for your LimelightTM hot tub are:
- Free Available Chlorine (FAC): 3.0-5.0 ppm - Total Alkalinity: 125-150 ppm
- Water pH: 7.4-7.6 - Calcium Hardness: 150-200 ppm
(Refer to Water Quality and Maintenance section for complete instructions.)
IMPORTANT: Turn on the jet pump for a least ten minutes after adding ANY hot tub water chemicals into the filter compartment.

Page 3
Page 3
• Clean the filter cartridge monthly to remove debris and mineral buildup which may affect the performance of the hydromassage jets, limit
the flow, or trip the high limit thermostat which will turn off the entire hot tub.
AVOIDING THE RISK OF HYPERTHERMIA
Prolonged immersion in hot water can result in HYPERTHERMIA, a dangerous condition which occurs when the internal temperature of the body
reaches a level above normal (98.6°F). The symptoms of hyperthermia include unawareness of impending hazard, failure to perceive heat, failure
to recognize the need to exit the hot tub, physical inability to exit the hot tub, fetal damage in pregnant women, and unconsciousness resulting in a
danger of drowning.
WARNING:
The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in hot tubs.
TO REDUCE THE RISK OF INJURY:
• The water in the hot tub should never exceed 104°F. Water temperatures between 100°F and 104°F are considered safe for a healthy
adult. Lower water temperatures are recommended for extended use (exceeding ten minutes) and for young children. Extended use can
cause hyperthermia.
• Pregnant or possibly pregnant women should limit hot tub water temperatures to 100°F. Failure to do so may result in permanent injury to
your baby.
• Do not use hot tub immediately following strenuous exercise.
AVOIDING THE RISK OF SKIN BURNS:
• To reduce the risk of injury, before entering a hot tub the user should measure the water temperature with an accurate thermometer, since
the tolerance of temperature-regulating devices may vary by as much as ±5°F.
• Test the water with your hand before entering the hot tub to be sure it’s comfortable.
SAFETY SIGN
Each LimelightTM hot tub is shipped with a SAFETY SIGN in the owner’s package. The sign, which is required as a condition of Product Listing,
should be permanently installed where it is visible to the users of the hot tub. To obtain additional SAFETY SIGNS, contact your Limelight dealer
and request Part #70798.
IMPORTANT HOT TUB INSTRUCTIONS
The following contains important hot tub information, and we strongly encourage you to read and apply them.
DO:
• Use and lock the vinyl cover when the hot tub is not in use, whether it is empty or full.
• Follow the hot tub Care and Maintenance recommendations stated in this manual.
• Use only approved accessories and recommended hot tub chemicals and cleaners.
DON’T:
• Leave the Limelight hot tub exposed to the sun without water or the cover in place. Exposure to direct sunlight can cause solar distress of
the shell material.
• Roll or slide the hot tub on its side. This will damage the siding.
• Lift or drag the vinyl cover by using the tie-down straps; always lift or carry the cover by using the handles.
• Attempt to open the electrical control box. There are no user serviceable parts inside. Opening of the control box by the hot tub owner will
void the warranty. If you have an operational problem, carefully go through the steps outlined in the Troubleshooting section. If you are not
able to resolve the problem, contact your authorized Limelight dealer. Many problems can easily be diagnosed over the telephone by an
Authorized Service Technician.

INSTALLATION INSTRUCTIONS
SITE PREPARATION
You probably have a spot picked out for your new hot tub, whether it’s indoors or outdoors, on a patio or on a
deck. Just make sure you check the following:
• Always put your hot tub on a structurally sound, level surface. A filled hot tub can weigh a great deal.
Make certain that the location you choose can support the weight of your filled hot tub.
• Don’t forget to level your hot tub before filling it. (See Hot Tub Leveling Instructions.)
• Locate your equipment compartment, which houses all of the electrical components, in a place where
water drainage will be away from it. Do not allow water into the equipment compartment. Water can cause
damage to the electronics, or may trip the circuit breaker on your house’s electrical panel.
• Leave yourself easy access to the circuit breakers in the subpanel.
• Never let water get into the subpanel. Your 230 volt hot tub’s subpanel is rain-tight when installed
correctly with the door closed. Periodically check these conditions and correct any flaws if detected.
• Leave access to the equipment compartment for periodic hot tub care and maintenance.
• Your hot tub is equipped with an air-intake screen located between the base of the equipment compartment (center of compartment) and
the ground. Make sure the screen remains clear of debris at all times, this is the only location that allows air to flow into the equipment
compartment.
OUTDOOR AND PATIO INSTALLATION
No matter where you install your new hot tub, it’s important that you have a solid foundation to support it. Structural damage to the hot tub
resulting from incorrect installation, or placement on an inadequate foundation, is not covered under the hot tub’s limited warranty.
If you install the hot tub outdoors, we recommend a reinforced concrete pad at least four inches thick. The reinforcing rod or mesh in the pad
should be attached to a #10 AWG bonding wire per national electrical codes (contact your local electrical code compliance inspector for more
information; inspection for proper grounding may be required before pouring concrete to form the slab).
If you place the hot tub on the ground, even temporarily, place stepping stones under the leveling areas (see Hot Tub Leveling Instructions). The
stones should be at least two inches thick and twelve inches square. Even with stones in place, the hot tub will inevitably settle and become
unlevel. Plus, a hot tub surrounded by dirt or grass will soon be filled with dirt or grass from users’ feet; therefore, it’s important to get it onto a
solid foundation as soon as possible.
DECK INSTALLATION
To be certain your deck can support your hot tub, you must know the deck’s maximum load capacity. Consult a qualified building contractor or
structural engineer. To find the weight of your hot tub, its contents and occupants, refer to the Hot Tub Specification chart. This weight per square
foot must not exceed the structure’s rated capacity, or serious structural damage could result.
INDOOR/BASEMENT INSTALLATION
Be aware of some special requirements if you place your hot tub indoors. Water will accumulate around the hot tub, so flooring materials must
provide a good grip when wet. Proper drainage is essential to prevent a build-up of water around the hot tub. When building a new room for the hot
tub it is recommended that a floor drain be installed. The humidity will naturally increase with the hot tub installed. Water may get into woodwork and
produce dry rot, mildew, or other problems. Check for airborne moisture’s effects on exposed wood, paper, etc. in the room. To minimize these
effects, it is best to provide plenty of ventilation to the hot tub area. An architect can help to determine if more ventilation must be installed.
Your Limelight dealership can help you with local information such as zoning regulations and building codes. They can also give you a copy of our
planning guide – just ask for Limelight hot tub Pre-Delivery Instructions.
WARNING: Please keep the area around your hot tub well ventilated when it is installed indoors or in a confined area. Inadequate ventilation
around the hot tub could cause a build-up of a higher-than-normal concentration of hot tub chemicals and/or bacterial fragments. These dispersed
hot tub chemicals and/or bacterial fragments can be inhaled, and may result in breathing difficulties or lung damage in certain people suffering from a
compromised immune system or respiratory infection. If you or other bathers are affected by this condition, please seek medical attention as soon as
possible.
Installation Instructions
WARNING
Lowering the top of the spa
to deck level substantially
increases the potential of
accidental entry. Contact
your LimelightTM Dealer for
more information and
consult a licensed building
contractor to design or
evaluate your custom
decking requirements.

Page 6
In addition to the previous information, properly clean and maintain your hot tub as follows:
• Follow all procedures in this Owner’s Manual and printed instructions on all water care (chemical) products packaging.
• Test the water regularly to ensure proper levels of sanitizers, pH, and other water care requirements.
• Drain, clean, and refill your hot tub with fresh water on a regular schedule, and in accordance with this owner’s manual.
• Clean the filter(s) at least once per month.
• Check to make sure you have proper circulation throughout your hot tub water system.
• Have hot tub users bathe before entering the hot tub water.
HOT TUB LEVELING INSTRUCTIONS
In order for your LimelightTM hot tub to operate properly, and the internal plumbing to drain completely, the hot tub must be level.
WARNING: Watkins Manufacturing Corporation recommends that a structural engineer or contractor be consulted prior to placing the hot
tub on an elevated deck, or platform.
IMPORTANT: Watkins Manufacturing Corporation reserves the right to change any specifications or design without incurring any obligation.
Hot Tub Leveling Preparation
Concrete sloped at 1/2 inch (1.3 cm) per 10 feet (305 cm) is preferred so that rain water and water spillover will run off and not puddle underneath
the hot tub (water under the hot tub for long periods of time may cause the wood to deteriorate). Other options are brick, stepping stone, or blocks.
It is important to note that soft surfaces, even when stepping stones are used to evenly distribute the weight of the hot tub, will have a tendency to
settle, thus resulting in an unleveled hot tub.
NOTE: Placing the hot tub on grass or dirt may increase the amount of debris which is inadvertently brought into the hot tub water and may cause
harm to your equipment as well as the hot tub surface, which is not covered under warranty.
Stepping stones or brick may settle
causing the spa to be unlevel.

ELECTRICAL REQUIREMENTS
AND PRECAUTIONS
Your Limelight™hot tub has been carefully designed to give you maximum safety against electric shock. Connecting the hot tub to an improperly
wired circuit will negate many of the hot tub’s safety features. Improper wiring may also cause electrocution, risk of fire, and other risks of injuries.
Please read and follow the electrical installation requirements and instructions for your specific hot tub model completely!
SERVICE NOTE: The Limelight hot tub is equipped with a power indicator which, in addition to showing the hot tub has power to it, has a diagnostic
function as well. It will begin blinking if the heater high-limit thermostat has tripped. If the power indicator light is blinking, follow the instructions in
the Troubleshooting section to identify and correct the cause. The power indicator will stop blinking once the problem has been corrected.
230 VOLT CONNECTED
Electrical Requirements
LIMELIGHT HOT TUB MUST BE WIRED IN ACCORDANCE WITH ALL APPLICABLE LOCAL ELECTRICAL CODES. ALL ELECTRICAL WORK
SHOULD BE DONE BY AN EXPERIENCED, LICENSED ELECTRICIAN. WE RECOMMEND THE USE OF APPROPRIATE ELECTRICAL CONDUIT,
FITTINGS, AND WIRE FOR ALL CIRCUITS.
An electrical subpanel containing two GFCI breakers is included with each 230 volt hot tub. We recommend that this subpanel be used to supply
power and protect the hot tub.
This subpanel requires a 50 amp, single phase, 230 volt, four wire service (two line, one neutral, one ground). The grounding conductor must be at
least the same gauge as the line conductors, but not less than #8 AWG.
Mount the subpanel in the vicinity of the hot tub, but not closer than five feet away, in accordance with all local codes. (N.E.C. 680-38 to 41-A-3).
INSTALLATION INSTRUCTIONS
1. To connect the electrical service, first remove the screws from the equipment compartment panel. Carefully pull the door panel away and
down in order to remove it completely from the hot tub.
2. Locate the IQ 2020
®
hot tub control box. Loosen the screws on the front of the control box. Remove the screws and the control box cover.
3. Route the electrical service from the subpanel into the hot tub equipment compartment.
NOTE: The subpanel must be placed in sight of the hot tub, at a minimum distance of five feet away.
4. Connect the supply conduit to the bottom of the IQ 2020 hot tub control box, using a 3/4” liquid-tight, flex conduit fittings.
WIRING CONNECTIONS
1. Identify the TB-1 terminal block, located inside the control box at the lower left-hand corner.
2. Connect the #12 AWG, BLUE wire, from the subpanel 20 amp breaker, terminal L1 to TB-1, terminal 1.
3. Connect the #12 AWG, RED wire, from the subpanel 20 amp breaker, terminal L2 to TB-1, terminal 3.
NOTE: The WHITE neutral wire must be attached to the LOAD neutral on the 230 volt, 30 amp breaker (not to the neutral bus bar in the subpanel).
The WHITE neutral wire coming from the breaker itself is already connected to the neutral bus bar.
4. Connect the #10 AWG, BLUE wire, from the subpanel 30 amp breaker, terminal L1 to TB-1, terminal 2.
5. Connect the #10 AWG, RED wire, from the subpanel 30 amp breaker, terminal L2 to TB-1, terminal 4.

NOTE: If both breakers immediately trip, verify that the #10 AWG WHITE neutral wire is connected from TB-1 terminal 5 to the N (load neutral)
terminal of the 30 amp subpanel breaker. Each breaker should be tested prior to each use. Here’s how:
1. Push the “TEST” button on each GFCI breaker, and observe it click OFF.
2. Wait 30 seconds, then push the breaker switch to the OFF (down) position (to ensure that it has completely disengaged), then push the
breaker switch to the ON (up) position. If you don't wait 30 seconds, the hot tub’s control panel may flash four lines on and off – try again.
If any of the GFCI breakers fails to operate in this manner, your hot tub may have an electrical malfunction, and you may be at risk of electrical
shock. Turn off all circuits and do not use the hot tub until the problem has been corrected by an authorized service agent.
WARNING: Removing or bypassing any GFCI breaker will result in an unsafe hot tub and will void the hot tub’s warranty.
IMPORTANT: Should you ever find the need to move or relocate your Limelight hot tub, it is essential that you understand and apply these
installation requirements. Your Limelight hot tub has been carefully engineered to provide maximum safety against electric shock. Remember,
connecting the hot tub to an improperly wired circuit will negate many of its safety features.
NOTE: Long wiring runs may require larger-gauge wire than stated.

OPERATING INSTRUCTIONS
Limelight™Hot Tubs are 230 volt permanently connected models. The Limelight Pulse™, Flair™and Glow™use a continuous heating system, this
means that the heater may turn on while the jet pump is operating which keeps your water hotter longer when the jets are in use.
Your Limelight hot tub comes with a subpanel which contains two GFCI circuit breakers - a 20 amp / 30 amp / 230 volt GFCI circuit breaker
system. The subpanel and hot tub must be “hardwired” by a licensed electrician using appropriate wire, conduit, and fittings.
The Limelight Pulse features one Wavemaster®9000 (2 1/2hp single speed) jet pump and one Wavemaster 9200 (2 1/2hp two speed) jet pump.
The Limelight Flair and Glow feature one Wavemaster 8000 (2 hp single speed) jet pump and one Wavemaster 8200 (2 hp two speed) jet pump.
The hot tubs have a No-Fault®titanium, high watt density heater. The heating system consists of a 4,000 watt (4 kW) heater. The Limelight hot
tubs are also equipped with an energy efficient low-flow circulation pump, and a high-limit thermostat for protection of user and equipment.
The heater will turn on while the jet pump is operating (after a 1-1/2 degree temperature drop) to help maintain the water temperature during hot
tub use. Factors such as the number of people using the hot tub, the air temperature, and the length of time the pump is operated will affect the
heating system’s ability to maintain the water temperature.
START-UP AND REFILL PROCEDURES
Your Limelight hot tub has been thoroughly tested during the manufacturing process to ensure reliability and long-term customer satisfaction. A
small amount of water may have remained in the plumbing after testing and, as a result, may have spotted the hot tub shell or the hot tub siding
prior to delivery. Before filling the hot tub, wipe the hot tub shell clean with a soft rag.
The following instructions must be read and followed exactly to ensure a successful start-up or refill.
CAUTIONS
•Do not fill the hot tub with hot water, as tripping of the high-limit thermostat may result.
• DO NOT CONNECT POWER TO AN EMPTY HOT TUB. Power to the hot tub automatically activates critical components within the
hot tub, such as controls, heater, circulation pump, and other systems. If power is supplied to these components prior to the hot
tub being filled, the components will be damaged, and this may result in a non-warranty component failure.
• Do not use your hot tub after filling until all of the steps listed below are completed.
• Do not add chlorine if treating your hot tub with polyhexamethylene biguanide (Biguanide, PHMB, eg. BaquaSpaTM) sanitizer.
• Do not use the FrestStart® 10,000 pre-filter if treating your hot tub with a polyhexamethylene biguanide (Biguanide, PHMB, i.e.
BaquaSpaTM ) sanitizer.
1. Close drain and fill the hot tub with water through the filter compartment. The water level of your Limelight hot tub should be maintained just
below the bottom of the pillow.
RECOMMENDED: Use the FreshStart 10,000 pre-filter to remove unwanted contaminants from the tap water.
IMPORTANT: Watkins Manufacturing Corporation does not recommend that the hot tub be filled with “softened” water, as this may damage
the hot tub’s equipment.
2. AFTER the hot tub has been filled with water and the equipment compartment door is secured, power must be applied to the hot tub.
•
Open the door of the electrical subpanel and reset the 30 amp GFCI breaker, verify that the system is primed (see step 3), then reset the 20 amp
breaker. Close and secure the subpanel door.
3. The jet pump, heating system, and all internal plumbing will achieve a partial prime as the hot tub is filled. To check the operation of the jet
system and to remove any remaining air from the heating system, push the JETS button two times to make the jet pumps run on high speed,
run for one minute. Once the jet system is fully operational (as indicated by strong, non-surging jets), priming of the hot tub is complete. Weak
or surging jets are an indication of a low water level condition or clogged filter cartridges.
IMPORTANT: Be sure the air control valves (see illustration in Air Control System section) are open by turning each one clockwise and
checking to see that the Diverter lever is pointing to the 3 o’clock position for the Flair model and 6 o’clock position for the Pulse model (see
illustration in Diverter System section). Combination jet faces can be turned to completely shut off jet flow, these jets should be open as well.
4. Adjust Total Alkalinity (TA) to 125 ppm, Calcium Hardness (CH) to 150 ppm, then hot tub water pH to between 7.4 and 7.6 These procedures
are listed in the “Water Quality and Maintenance” section.
IMPORTANT: Add hot tub water chemicals directly into the filter compartment with the jet pump on high speed for at least ten minutes.
OPERATION NOTE: Adjusting the Total Alkalinity as the first step is important, as out-of-balance TA will affect your ability to adjust the pH
correctly and will prevent the sanitizer from operating effectively.
5. Superchlorinate the hot tub water by adding 1-1/2 teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of hot tub water. Run the
jet pump for a ten-minute period (clean cycle).
6. During the super-chlorination period, rotate the diverter lever through both operating positions, letting the hot tub water circulate (with jets on)
for equal periods of time. For example, leave the diverter lever in each position for approximately two to three minutes.
Page 12
Electrical Requirements
Page 12
Operating Instructions

OPERATION NOTE: Depending on your hot tub, the diverter lever is designed to operate in either the 3 o’clock and 9 o’clock positions or in
the 6 o’clock and 12 o’clock positions (the Glow™does not use a diverter lever).
7. Set the temperature control to the desired temperature between 100°F and 104°F (36°C and 40°C), then place the vinyl cover on the hot tub
and allow the water temperature to stabilize (approximately 24 hours). Make sure you secure the cover in place using the cover locks.
Periodically check the hot tub water temperature. When the water temperature climbs above 90°F (32°C), proceed to the next step.
8.
Rotate the diverter lever to the primary position (3 o’clock for the Flair model or 6 o’clock for the Pulse model ) and turn on the jets for ten
minutes to circulate the hot tub water. After the jets have run for ten minutes (clean cycle), test the hot tub water for Free Available Chlorine
(FAC) residual. If the residual is between 3 and 5 ppm on the test strips (found in the test kit) go on to the next step. If the residual is less than 3
ppm, superchlorinate the hot tub water by adding 1-1/2 teaspoons of chlorine (sodium dichlor) per 250 gallons
(950 liters) of hot tub water. Run
the jet pump to circulate the hot tub water for a ten-minute period (clean cycle).
9. Rotate the diverter lever to next position (9 o’clock for the Flair model or 12 o’clock for the Pulse model ) and let the hot tub water circulate
(using the jet) for ten minutes. Test the hot tub water for Free Available Chlorine (FAC) residual. If the residual is between 3 and 5 ppm on the
test strips (found in the test kit) go on to the next step. If the residual is less than 3 ppm, superchlorinate the hot tub water by adding 1-1/2
teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of hot tub water. Run the jet pump to circulate the hot tub water for a ten-
minute period (clean cycle).
10. Recheck the Total Alkalinity (TA) at 125 ppm, Calcium Hardness (CH) at 150 ppm, then hot tub water pH at between 7.4 and 7.6.
Operational Note: Make sure you adjust your Total Alkalinity first, as an out-of-balance condition will affect your ability to adjust the pH
correctly, and will prevent the sanitizer from operating effectively. The hot tub is ready for use when the hot tub water has circulated
through both diverter lever operating position and the chlorine level remains between 3 ppm and 5 ppm.
11. The hot tub temperature is pre-programmed to reach 102°F (39°C), and will normally do so within 18 to 24 hours. You may raise the water
temperature by pressing the TEMP (+) button on the control panel, or lower it by pressing TEMP (-) button. After a few hours, the water
temperature will remain within 1-1/2 degrees of your selected temperature. To prevent tampering, you can lock your desired temperature
setting. Refer to the Control Panel section for details.
NOTE: Allowing the jet pump to operate for long uninterrupted periods of time with the cover in place will cause a rise in the hot tub water
temperature. All hot tubs are equipped with a safety device to reduce the risk of component damage or personal injury, should the jet pump
be left running continuously for a long period of time. After two hours of continuous operation, the jet pump controller will automatically turn
off the jet pump.
DIVERTER SYSTEM (PULSE & FLAIR ONLY)
With your Limelight™hot tub’s diverter system design, you can control the massaging action of your hot tub.
Using the diverterlever, the jets are activated in sets, known as jet systems.
The Limelight PulseTM hot tub has two jet systems that are activated by turning the diverter
lever to the 6 or 12 o’clock position while the Limelight FlairTM has two jet systems that are
activated by turning the diverter lever to the 3 or 9 o’clock position. To access a different jet
system, simply turn the diverter system lever. The orientation is based on standing at the control panel.
Please consult the jet system menus on the following page to determine which jets are activated with each
diverter lever position. Or just jump in and play – turn the lever and see what happens.
AIR CONTROL SYSTEM
The Air Control System allows you to control the intensity of the Direct Hydromassage jets by
adjusting the mixture of air and water. Turn the Air Control lever clockwise to decrease the
intensity of the Direct hydromassage jets and counterclockwise to increase the intensity.
JETS
DIRECT HYDROMASSAGE JETS
Direct hydromassage jets are small, producing a precisely narrow stream of massaging action. They are placed in groups to
perform a soft, soothing massage on your back, neck, and shoulders.
COMBINATION HYDROMASSAGE JETS
These jets deliver a great massage to the feet, back and shoulder areas. These jets may be adjusted to provide either a
stationary, direct stream, or, by positioning the nozzle to one side, a variety of rotating massage patterns. Also, the speed
of the rotation can be changed by rotating the jet faceplate from a full stream, to shutting the jet completely off. To avoid
damage to your spa’s plumbing and components, do not turn off more than half of these jets at the same time.

COMBINATION XL HYDROMASSAGE JETS
These large jets may be adjusted to provide either a stationary, direct stream, or, by positioning the nozzle to one side, a
variety of rotating massage patterns. Also, the speed of the rotation can be changed by rotating the jet faceplate from a
full stream, to shutting the jet completely off. To avoid damage to your spa’s plumbing and components, do not turn off
more than half of these jets at the same time.
COMBINATION JETS MAINTENANCE
If you notice that either the Combination or Combination XL jets spin slower than when the spa was new, or the jets are sticking, the cause may be
built-up deposits inside the jet bearings. To remove the deposits, use the following instructions:
1. With the spa off, rotate the combination jet face counter-clockwise until it stops.
2. Once the face stops rotating, push in and use a little extra force to rotate the face even more counter-clockwise past the locking position until
it stops. Pull face with the body away from the spa.
3. After flushing the bearing inside the body with water, spin the rotating eye, it should spin very freely. If it does not, place the bearing end in a
cup of vinegar (the vinegar will soften any deposits). Leave soaking overnight. The next day, flush with water and repeat the spin test.
NOTE: If it still doesn’t spin freely, a second night of soaking is required. If the bearing still does not spin, you will need to purchase a
replacement assembly from your LimelightTM dealer.
4. To replace, position the cutout at the back end of the face body downward and push the face body back into the spa fitting. Slightly rotate
face body in either direction until you feel the body align with the fitting, then press firmly on the face body. Once seated, push and rotate the
face clockwise using a little extra force to overcome the locking position. If the face does not rotate, remove and rotate face body 180° and
repeat this step. Turn the jet pump on, the combination jet should spin freely.
WATER FEATURE
The Limelight PulseTM, FlairTM, and Glow™ hot tubs come equipped with a Vidro™water feature. This water feature can be turned on or off when the
two-speed pump is on low speed (tranquil mode) or high speed. To function correctly, the water feature on/off lever must be placed in the ffuulllloonn
position only.
If the lever is not in the ffuulllloonnposition when the pump is on high speed, it is likely that the water feature will project water substantially farther out
into the hot tub as the on/off lever is opened. This is not proper operation. If this occurs, the pump should be turned off, the water feature lever
rotated to the full on position and the pump turned on again.
CAUTION: Partial blockage of water flow at entrance of water feature will cause the water to flow farther into or over the hot tub.
