n 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 spa) by children
under 5 years of age. Your Hot Spring®Spa 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 Hot Spring®Spa Dealer can provide information on which permits may be required.
Congratulations on your decision to enjoy the finest spa available...
Welcome to the growing family of Hot Spring®Spa owners.

I. 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 spa unless they are supervised at all times.
WARNING:
•To reduce the risk of injury, do not permit children to use this product 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 spa for your children’s safety. Every Hot Spring®Spa 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 child to enter the spa 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 the children are careful when entering or exiting the spa.
DON’T:
•Allow children to climb onto the spa cover.
•Allow children to have unsupervised access to the spa.
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. 8 AWG
(8.4 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.
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.
•Your spa is provided with a Ground Fault Circuit Interrupter for user and equipment protection. To ensure proper operation of this
important safety device, test according to the following instructions per electrical configuration.
Cord-Connected 115 volt, 20 amp models: The GFCI is located at the end of the power cord. Before each use, with the unit operating,
push the TEST button. The unit should stop operating and the GFCI power indicator will go out. Wait 30 seconds and then reset the GFCI
by pushing the RESET button. The GFCI power indicator will turn on, restoring power to the spa. If the interrupter does not perform in this
manner, there may be an electrical malfunction and with it, the possibility of an electric shock. Disconnect the power until the problem has
been corrected.
230 volt, permanently installed or converted models:
•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 (2.6 mm diameter)) solid copper wire to any metal ladders, water pipes, or
other metal within 5 feet (1.5 m) of the spa 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 spa.
•Your spa is provided with a suitably rated circuit breaker to open all ungrounded supply conductors.
•Your spa uses ground fault circuit interrupters in the electrical subpanel. Before each use of the spa 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

Page 3 Safety Information
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 spa’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 spa may be installed within 5 feet of a metal surface if each metal surface is
permanently connected by a minimum No. 10 AWG (2.6 mm diameter)) 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 spa. Failure to maintain a
safe distance may result in death or serious personal injury due to electrocution if the appliance should fall into the spa.
•Install your spa is such a way that drainage is away from the electrical compartment and from all electrical components.
DO:
•Be sure your spa is connected to the power supply correctly - use a licensed electrical contractor.
•Disconnect the spa from the power supply before draining the spa or servicing the electrical components.
•Test the Ground Fault Circuit Interrupter(s) before each use.
DON’T:
•Use the spa with the equipment compartment door removed.
•Place electrical appliances within 5 feet (1.5m) of the spa.
•Use an extension cord to connect the spa 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 (filter standpipes) located in the filter compartment.
•The suction fittings in the spa are sized to match the specific water flow created by the pump. Should the need arise to replace the
suction fittings or the pump, be sure that the flow rates are compatible.
•There is a danger of slipping and falling. Remember that wet surfaces can be very slippery. Take care when entering or exiting the spa.
Increased side effects of medication
•The use of drugs, alcohol or medication before or during spa use may lead to unconsciousness with the possibility of drowning.
•Persons using medications should consult a physician before using a spa; 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, antihistimines or anticoagulents should not use the spa.
Health problems affected by spa use
•Pregnant women should consult a physician before using spa.
•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 spa.
Unclean water
•Keep the water clean and sanitized with correct chemical care. The recommended levels for your Hot Spring®Spa are:
Free Available Chlorine (FAC): 3.0-5.0 ppm
Water pH: 7.4-7.6
Total Alkalinity: 125-150 ppm
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 spa water chemicals into the filter compartment.
•Clean the filter cartridges at least 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 spa.

Safety Information Page 4
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 spa, physical inability to exit the spa,
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 and spas.
TO REDUCE THE RISK OF INJURY:
•The water in the spa 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 10 minutes)
and for young children. Extended use can cause hyperthermia.
•Pregnant or possibly pregnant women should limit spa water temperatures to 100°F. Failure to do so may result
in permanent injury to your baby.
AVOIDING THE RISK OF SKIN BURNS:
•To reduce the risk of injury, before entering a spa 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 spa to be sure it’s comfortable.
SAFETY SIGN
Each Hot Spring®Spa 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 spa. To obtain additional SAFETY
SIGNS, contact your Hot Spring®Spa Dealer and request Part #70798.
IMPORTANT SPA INSTRUCTIONS
The following contains important spa information, and we strongly encourage you to read and apply them.
DO:
•Use and lock the cover when the spa is not in use, whether it is empty or full.
•Follow the Spa Care and Maintenance recommendations stated in this manual.
•Use only approved accessories and recommended spa chemicals and cleaners.
DON’T:
•Leave the Hot Spring®Spa 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 spa on its side. This will damage the siding.
•Lift or drag the cover by using the cover lock 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 spa 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 Hot
Spring®Spa Dealer. Many problems can easily be diagnosed over the telephone by an Authorized Service
Technician.

III. INSTALLATION INSTRUCTIONS
SITE PREPARATION
Y
ou probably have a spot picked out for your new spa, whether it’s indoors or outdoors, on a patio or on a deck. Just make
sure you check the following:
•Always put your spa on a structurally sound, level surface. A filled spa can weigh a great deal. Make certain that the
location you choose can support the weight of your filled spa.
•Don’t forget to level your spa before filling it. (See the Spa Leveling section of this manual.)
•Locate your equipment compartment, which houses all of the electrical components, in a place where water will drain
away from it. Allowing water into the equipment compartment can damage the electronics, or may result in tripping
your house’s circuit breaker.
•Leave yourself easy access to the circuit breakers in the subpanel (230 volt models), or to the interrupter switch on the
end of the power cord (115 volt models).
•Never let water get into the subpanel (230 volt models), into the interrupter switch (115 volt models), or into the
electrical outlet that your spa is plugged into. Your 115 volt Hot Spring®Spa comes with a protective box designed to
keep out rain and water from sprinkler systems. Your 230 volt spa’s subpanel is raintight 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 spa care and maintenance.
•If your spa is going to be installed in a location known to be frequented by mice, rats or other nocturnal creatures,
Watkins Manufacturing Corpoation recommends covering the access opening to the spa’s equipment compartment
with a heavy gauge screen material available at your local hardware store.
WARNING: Damage to the spa’s equipment compartment components or internal plumbing as a result of rodent
infestation is NOT covered under your warranty!
OUTDOOR AND PATIO INSTALLATION
N
o matter where you install your new spa, it’s important that you have a solid foundation to support it. Structural damage to
the spa resulting from incorrect installation or placement on an inadequate foundation is not covered under the spa’s
limited warranty.
If you install the spa 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 spa on the ground, even temporarily, place stepping stones under the leveling areas (see Spa Leveling
Instructions). The stones should be at least two inches thick and twelve inches square. Even with stones in place, the spa will
inevitably settle and become unlevel. Plus, a spa surrounded by dirt or grass will soon be filled with dirt or grass
from users’feet; therefore, it is important to get it onto a solid foundation as soon as possible.
DECK INSTALLATION
T
o be certain your deck can support your spa, you must know the deck’s maximum load capacity. Consult a
qualified building contractor or structural engineer. To find the weight of your spa, its contents and
occupants, refer to the Spa Specification chart. This weight per square foot must not exceed the structure’s
rated capacity, or serious structural damage could result.
INDOOR/BASEMENT INSTALLATION
B
e aware of some special requirements if you place your spa indoors. Water will accumulate around the spa,
so flooring materials must provide a good grip when wet. Proper drainage is essential to prevent a build-up
of water around the spa. When building a new room for the spa it is recommended that a floor drain be installed.
The humidity will naturally increase with the spa installed. Water may get into woodwork and produce dryrot,
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 spa area. An architect can help to
determine if more ventilation must be installed.
Hot Spring®Spas are equipped with a jet pump shroud to remove excessive heat from the equipment
compartment. Find this vent and be sure the vent is not blocked by anything, including carpeting.
Your Hot Spring®Spa Dealer can help you with local information such as zoning regulations and building codes.
He can also give you a copy of our planning guide–just ask for Hot Spring®Spa Pre-Delivery Instructions.

Warning!
Warning!
Watkins Manufacturing
Corporation recommends
that the Hot Spring®Spa be
installed above ground.
Lowering the top of the spa
to ground level, or
employing decking which
raises standing level toward
the top of the spa
substantially increases the
hazard of accidental entry.
Consult a licensed building
contractor to design or
evaluate your custom
decking requirements.

SPA LEVELING INSTRUCTIONS
I
n order for your Hot Spring®Spa to operate properly and the internal plumbing to drain completely, the spa must be
level. If the spa is to be installed on an uneven or unlevel foundation, shimming of the spa is required.
NOTE: Due to the large size of the Landmark®and Grandee®Spas, Watkins requires that these spas be installed
on a level 4”- (10.1 cm) thick concrete pad and NOT shimmed in any manner.
WARNING: Watkins Manufacturing Corporation recommends that a structural engineer or contractor be consulted prior
to placing the spa on an elevated deck or platform.
IMPORTANT: Watkins Manufacturing Corporation reserves the right to change any specifications or design without
incurring any obligation.
Approved Shim Material
•Cedar shingles
•Redwood
•Exterior rated plywood
•Exterior rated lumber
The shims used should vary in thickness from 1/4- to 1/2-inch (0.6 cm to 1.2 cm) and should be cut into 2”by 4”(5 cm
by 10 cm) rectangles.

models)
1. Using a 6-foot carpenter’s level (or a shorter level and a straight 2”x 4”, 8-foot-long board, or a board 5 cm by 10
cm, 2.4 meters long), check the spa to identify the highest and lowest corners.
2. With one end of the level resting on the highest corner of the spa (and the opposite end resting on the lowest
corner), gently raise the lower end of the level by placing shims between the spa shell and the level, until the level
itself is level. This will tell you how many shims are needed at that lowest corner.
3. Now carefully pivot the level, keeping the shimmed end where it is, until the other end of the level rests on one of the
other corners. Check for level. Adjust the end of the level using the procedure above. Carefully pivot the level again
to the last corner, leaving the pivot end at its original location, and repeat the procedure. Whatever shims are on the
three corners are the ones you will place under those corners in the next steps.
4. Remove the level and set it aside. Carefully remove the shims and keep them together, remembering the corner
from which each set of shims came.
5. With more than one person lifting, lift the lowest side of the spa (the one with the most shims), and place a 4”x4”
(10 cm x 10 cm) block under the spa base, at the center of the side lifted.
6. Refer to the base support diagram for your spa to locate the leveling points for the elevated corners. Place the set of
shims corresponding to each corner directly under its designated leveling point.
7. Lift the spa, remove the support block, and set the spa on the shims. Repeat steps 5 through 7, if necessary, for the
opposite side of the spa.
8. Use the level to check the level of the spa. Make any adjustments necessary.
9. Refer to the base support diagram for your spa to locate the remaining leveling points, each of which must now also
be shimmed, and carefully slide “helper”shims under the spa at their designated locations. These helper shims
should create a snug fit between the foundation and the spa’s base structure. If it is necessary to lift the spa in order
to place the helper shims, use care not to kick out the original corner shims.
The following base support diagrams for the Vanguard™, Sovereign®, Prodigy®and Jetsetter®Spas indicate the
recommended shimming points.

ELECTRICAL REQUIREMENTS AND
PRECAUTIONS
Y
our Hot Spring®Spa has been carefully designed to give you maximum safety against electrical shock. Connecting
the spa to an improperly wired circuit will negate many of the spa’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 spa model completely!
SERVICE NOTE: All Hot Spring®Spa models are equipped with a power indicator which, in addition to showing the spa
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 PERMANENTLY CONNECTED MODELS
•Landmark®(Model S)
•Grandee®(Model G)
•Vanguard™(Model V)
HOT SPRING®SPAS 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 spa. We recommend that this
subpanel be used to supply power and protect the spa.
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 #10 AWG. A minimum
#10 AWG solid copper bond wire is also required.
Mount the subpanel in the vicinity of the spa, 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 door. Carefully pull the
door panel away and down in order to remove it completely from the spa.
2. Locate the IQ 2020™spa 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 spa equipment compartment. Position the conduit in the
recess provided between the frame and door. Install the supply conduit so as not to block the drain valve.
NOTE: The subpanel must be placed in sight of the spa, at a minimum distance of five feet away.
4. Connect the supply conduit to the bottom of the IQ 2020™spa control box, using a minimum of 3/4”liquid-tight, flex
conduit fittings.
WIRING CONNECTIONS
1. Identify the TB-1 terminal block, located inside the IQ 2020™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 2.
3. Connect the #12 AWG, RED wire, from the subpanel 20 amp breaker, terminal L2 to TB-1, terminal 4.
4. Connect the #12 AWG, WHITE wire, from the subpanel 20 amp breaker, terminal N (load neutral) to TB-1, terminal 5.
NOTE: The WHITE neutral wire must be attached to the LOAD neutral on the 230 volt, 20 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.
5. Connect the #10 AWG, BLUE wire, from the subpanel 30 amp breaker, terminal L1 to TB-1, terminal 1.
6. Connect the #10 AWG, RED wire, from the subpanel 30 amp breaker, terminal L2 to TB-1, terminal 3.
7. Connect the #10 AWG, GREEN wire, from the subpanel GROUND bar to TB-1, system ground terminal.
8. Using the pressure wire connector provided on the outside of the control box, bond the spa to all exposed metal
equipment or fixtures, handrails, and the concrete pad (if applicable) per N.E.C. Article 680 and local codes.
