Important!
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 spa) by children under 5
years of age. Your HOT SPOT 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 SPOT dealer can provide information on which permits may be required.
Watkins Manufacturing Corporation congratulates you on your decision to enjoy the finest
spa available... Welcome to the growing family of Hot Spot ® spa owners.

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
No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 bond wire.
dECk INSTAllATION
To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pagesofthismanual.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 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 indoors. 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 spa area. An architect can help to determine if more ventilation must be installed.
Your spa dealer can help you with local information such as zoning regulations and building codes.
WARNING: Please keep the area around your spa well ventilated when it is installed indoors or in a confined area.
Inadequate ventilation around the spa could cause a build-up of a higher-than-normal concentration of spa chemicals and/or bacterial fragments.
These dispersed spa 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.
In addition to the above, properly clean and maintain your spa 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spa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spawatersystem.
• Havespausersbathebeforeenteringthespawater.
SPA lEVElING PREPARATION
Concrete sloped at ½ 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 spa (water under the spa 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 spa, will have a tendency to
settle, thus resulting in an unleveled spa.
NOTE: Placing the spa on grass or dirt may increase the amount of debris which is inadvertently brought into the spa water and may cause harm
to your equipment as well as the spa surface, which is not covered under warranty.
Spa models can not be shimmed. Make sure the pad where the spa will be placed onto is level as illustrated above. No other leveling is needed.

SPA COVER INSTAllATION
• Placethecoversquarelyonthespa.
• Positionthetie-downlocksincludedwithyourcoveronthesideofthespasothattheyareeasilyreachedbythecovertie-downstraps.
Allow for about ½ inch (1.3cm) to ¾ inch (1.9cm) slack in the straps to make it easy to insert straps into locks and to compensate for vinyl
shrinkage in cold weather.
• Attachthelockswiththescrewsprovidedandinsertthecovertie-downstrapsintothelocks.
NOTE: Keepingthecoverinplaceanytimethespaisnotinusewillreducetheamountoftimethe

ELECTRICAL INSTALLATION
SElECTING THE VOlTAGE FOR YOUR SPA
The TX operates on 115 volts 15 amp and the SX operates on 115 volts 20 amp 60 Hz. Both the SX and TX can also be converted to either 115 volt 30
amp or 230 volt 50 amp. The TEMPO, RELAY and RHYTHM models require a dedicated 230 volt power supply. When the TX or SX spas are connected
to 115 volts 15/20 amp, the
heater will provide approximately 1000 watts of heat only when the pump is operating in LOW speed and the thermostat is
calling for heat. When the TX, SX spas are connected to 115 volts 30 amp, the heater will provide approximately 1000 watts of heat when the pump
is operating in LOW or HIGH speed and the thermostat is calling for heat. When the TX or SX are connected to 230 volts 50 amps, the heater will
provide approximately 4000 watts of heat when the pump is operating in LOW or HIGH speed and the thermostat is calling for heat.
All electrical connections must be made in accordance with the wiring information contained in the electrical control box or on the back of the field
wiring access panel of the equipment module.
115 VOLT INSTALLATION
Spas provided with a factory- installed power supply cord are to be plugged into a grounded, grounding type, 115 volt, 15 ampere receptacle (TX)
or 20 ampere receptacle (SX model). No other electrical appliance or fixture can be used on this circuit.
IMPORTANT: Under NO circumstances should an extension cord be used. Use of an extension cord will seriously degrade the performance of the
equipment module and can create an electrical hazard.
230 VOLT INSTALLATION
When using 230 volt power supply, installation of a 50 amp dedicated circuit is required. Your spa must be hard wired direct to a GFCI-protected
subpanel by a licensed electrician. A wiring diagram is provided inside the equipment module showing where the connections are to be made.
ELECTRICAL REQUIREMENTS AND PRECAUTIONS
Your HOT SPOT
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 spa completely!

9. Connect the #10 AWG, GREEN wire from the sub-panel GROUND bar to TB-1 terminal GROUND.
The GFCI breaker inside the sub-panel supplies all of the power to the spa. Before each use, open the sub-panel and press the TEST button
located on the sub-panel GFCI breaker. The breaker should snap into the “tripped” position and the spa should stop operating. Reset the sub-panel
GFCI breaker by completely pressing the breaker switch down, into the OFF position. Then, flip the breaker switch up, into the ON position. Power
should be restored and the spa should resume operation.
If the GFCI breaker fails to operate 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.
IMPORTANT: Should you ever find the need to move or relocate your HOT SPOT spa, it is essential that you understand and apply these
installation requirements. Your HOT SPOT spa has been carefully engineered to provide maximum safety against electric shock. Remember,
connecting the spa to an improperly wired circuit will negate many of its safety features.

OpERATINg INSTRUCTIONS
START-UP ANd REFIll PROCEdURES
Your HOT SPOT
spa 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 spa shell or the spa siding prior to
delivery. Before filling the spa, wipe the spa 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spawithhotwater,astrippingofthehigh-limitthermostatmayresult.
• DONOTCONNECTPOWERTOANEMPTYSPA.Powertothespaautomaticallyactivatescriticalcomponentswithinthespa,such
as controls, heater, and other systems. If power is supplied to these components prior to the spa being filled, the components will be
damaged, and this may result in a non-warranty component failure.
• Do not leave spa uncovered when filling. Solar distress can damage shell.
• Donotuseyourspaafterfillinguntilallofthestepslistedbelowarecompleted.
• Donotaddchlorineiftreatingyourspawithpolyhexamethylenebiguanide(Biguanide,PHMB,eg.BaquaSpa®) sanitizer.
• Beforefillingyourspaforthefirsttime,removetheequipmentcompartmentdoorandchecktoensurethattheunionsoneithersideofthe
pump(s) and heater are hand-tight.
1. Ensure the drain is closed. Insert the end of a garden hose into the filter compartment and begin filling the spa. The water level of your
HOT SPOT spa should be maintained at a level one inch above the highest jet in the spa.
RECOMMENDED: Use the Clean Screen™pre-filter to remove unwanted contanimants from the tap water.
IMPORTANT: Watkins Manufacturing Corporation does not recommend that the spa be filled with “softened” water, as this may damage the
spa’sequipment.
2. AFTER the spa has been filled with water and the equipment compartment door is secured, power must be applied to the spa.
• Cord connected models: Connect the GFCI to the waterproof receptacle and push the RESET button on the GFCI.
• Hard wired models: Open the door of the electrical subpanel and reset the GFCI breaker. Close and secure the subpanel door.
3. The jet pump(s), heating system and all internal plumbing will achieve a partial prime as the spa is filled. To check the operation of the jet
systemandtopurgeanyremainingairfromtheheatingsystem,pushtheJETSbuttononthecontrolpadtwice(threetimesforTEMPO &
RELAY) to make the jet pump(s) run on high speed for one minute. Once the jet system is fully operational (as indicated by strong, non-
surging jets), priming of the spa is complete. If you do not feel a steady stream of water from your jets, refer to the instructions for priming the
pump in the SPA TROUBLESHOOTING section in the back of this manual.
4. Adjust Total Alkalinity (TA) to 40-120 ppm, Calcium Hardness (CH) to 50-150 ppm, then spa water pH to between 7.2 and 7.6. These
procedures are listed in the “Water Quality and Maintenance” section.
IMPORTANT: Add spa water chemicals directly into the filter compartment after activating “Clean Cycle”
(Press SET, then JETS button).
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 spa water by adding 1½teaspoons of chlorine (sodium dichlor) per 250 gallons (950 liters) of spa water into the filter
compartmentafteractivating“CleanCycle”(PressSET,thenJETSbutton)thejetswillremainonhightocirculatethespawaterforaten-
minute period.
6. Set the temperature control to the desired temperature between 100ºF (38ºC) and 104ºF (40ºC), then place the cover on the spa 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
spa water temperature. When the water temperature climbs above 90ºF (32ºC), proceed to the next step.
7. PressSET,thenJETSbuttontorunthecleancyclefor10minutestocirculatethespawater.Afterthecleancycleiscomplete,testthespa
water for Free Available Chlorine (FAC) residual, If the residual is between 3 and 5 ppm on the test strips (found in most chemical test kits) go
on to the next step. If the residual is less than 3 ppm, superchlorinate the spa water by adding 1½ teaspoons of chlorine (sodium dichlor) per
250 gallons (950 liters) of spa water, while running the clean cycle.
8. Recheck the Total Alkalinity (TA) to 40-120 ppm, Calcium Hardness (CH) to 50-150 ppm, then spa water pH at between 7.2 and 7.6.
OPERATION NOTE: Make sure you adjust you 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 spa is ready for use when the spa water has circulated and the
chlorine level remains between 3 ppm and 5 ppm.
9. The spa temperature is pre-programmed to reach 100ºF (38ºC), and will normally do so within 18 to 24 hours. You may raise the water
temperature by pressing the TEMP UP (
 ) button on the control panel, or lower it by pressing the TEMP DOWN () button. After a few hours
the water temperature will remain within 3ºF (1.5ºC) of your selected temperature.
Operating Instructions Page 15

OPERATION NOTES:
1. Your spa is equipped with a ten-minute timer delay on the heating/maintenance mode. Whenever the jet pump has been turned off (and a
three-degree temperature drop has occurred) or the temperature control has been turned up, it will take ten minutes before the low speed of
thejetpumpandheaterbecomeactivated.AlwayspushtheJETSbuttontoturnoffthejetpumpwhenexitingthespa.Inthestandard115
volt, 15 amp electrical configuration, the heating system does not operate simultaneously with the high speed pump. On the 230-volt system,
the heating system does operate simultaneously with the high speed pump.
2. The spa controller has an automatic two hour “time-out” feature should the high speed jet mode be left on inadvertently. After one hour of
continuous operation, the controller will automatically return to the maintenance/heating mode.
3. The spa controller also has a six-hour “time-out” feature should the light be left on inadvertently. After six hours of continuous operation,
the controller will automatically turn the light off.
HEATING ANd HYdROMASSAGE SYSTEMS
The HOT SPOT spas use two-speed jet pumps to operate hydromassage jets and to circulate the spa water through the heating system (the
TEMPO , RELAY and RHYTHM are also equipped with a single speed jet pump used for jets only). The low speed mode of the pump, which is
activated automatically by the control thermostat, will cause the spa water to be drawn slowly in through the filter, the heater, and into the pump.
Thepump,inturn,willpushthewaterbackintothespathroughthejets.WhentheJETSbuttonispushedonetime,thespausercanactivate
the low speed of the jet pump. (The heater may or may not be on, depending on whether the control thermostat has indicated a demand for
heat.) When the JETS button is pushed a second time, the high speed of the jet pump will be activated. (This will automatically deactivate the
heater if it is operating in a standard 115 volt 15 or 20 amp system.)
In the 230 volt electrical system, if a drop in the water temperature has occurred, the spa heater will operate simultaneously when the jet pump is
operating on high speed. In a standard 115 volt 15 or 20 amp electrical system, the spa heater will not operate simultaneously when the jet pump
is operating on high speed, even if a drop in the water temperature has occurred. In either electrical configuration, when the high speed mode of
the jet pump is turned off, the spa will enter a ten-minute “tranquil mode.” During this time the heating system (and simultaneous operation of the
jetpumpatlowspeed)willnotoperate(unlesstheJETSbuttonispushed),evenifthewatertemperaturehasdroppedbelowthecontrolsetting.
Once the ten-minute period has expired, the spa controller will switch to the maintenance mode and the heating system will be automatically activated.
The HOT SPOT spas are equipped with a state-of-the-art heating system. The system uses an exclusive “flow through” No-Fault
®stainless steel
heater.
HYDROMASSAGE JETS
The larger jets in your spa allow you to re-direct the jet stream by changing the position of the nozzle.
Regulate the force of the massage by rotating the jet face clockwise to reduce the force or counter-clockwise to increase the force. Notice that
turningofftheflowtosomejetsincreasestheflowtotheotherjets.Toavoiddamagetoyourspa’splumbingandcomponents,do not turn off
more than half of these jets at the same time.
PRECISION
PRECISION jets are small. They are designed to perform a soft, soothing massage on your feet, calf, back and shoulders. The Air Control levers
are used to change the air intensity of a group of PRECISION jets simultaneously.
AIR CONTROL SYSTEM
AIR CONTROL VALVE: Turning the air control lever to the left position allows for the same volume of air to flow to all individual jets and
PRECISION jets simultaneously. The jet faceplate on the larger jets is then used to control the water intensity of each hydromassage jet.
NOTE: Always turn the air control lever to the right position anytime the spa is not being used. This will help make the spa operate more quietly
and heat more efficiently when the vinyl cover is in place.
WATERFALL VALVE (TEMPO, RELAY & RHYTHM MODELS ONLY)
The TEMPO, RELAY & RHYTHMspasareequippedwithacascadingwaterfeature.ItisactivatedbypressingtheJETSbuttonupto3times
when the jets are off and turning the waterfall valve counterclockwise. The flow is regulated by turning the valve to the desired position.
When not in use turn the on/off valve to the OFF position.
MOTO-MASSAGE JET (SX & TX MODELS ONLY)
The MOTO-MASSAGE jet automatically travels up and down in a sweeping motion, simulating the natural stroking effects of a manual massage.
The intensity and speed of the MOTO-MASSAGE jet may be adjusted by turning the Air Control lever.
Page 16 Operating Instructions

SAFETY EQUIPMENT
A. GFCI: The Ground Fault Circuit Interrupter, located on the end of the power cord (115 Volt models only), is a safety device that is designed to
sense as little as 5 milliamps of electrical current leakage to ground. It is very important to protect a GFCI from rain and other moisture. Watkins
Manufacturing Corporation recommends that the GFCI be tested before each use to ensure it is functioning correctly.
TO TEST THE GFCI:
Cord-Connected models: Before each use, with the spa operating, push the TEST button (located on the front of the GFCI). The GFCI
breaker should trip to the “off” position, disconnecting power to the spa. Reset the GFCI by pushing the RESET button. The spa will now
operate normally. If the interrupter does not perform in this manner, it is an indication of an electrical malfunction and the possibility of an
electric shock. Unplug the spa until the fault has been identified and corrected.
Hard Wired models: The GFCI breaker is located inside the 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 switching
it completely off and then completely on. The switch should then stay on.
B. HEATER HIGH-LIMIT SWITCH: The heater high-limit sensor is located on the heater assembly. If for any reason the internal temperature
of the heater exceeds 119°F (48°C), the high-limit circuit will trip and turn off the spa. The control panel display will display - - - - - and the
READY incon will flash for the all spa models. The heater high-limit may be reset when the water temperature within the heater has cooled
to approximately 110°F (43°C). Reset the heater high-limit by simply disconnecting power to the spa for thirty seconds. The cause of the
overheating must be located to prevent a recurrence. The most common cause of limit-tripping is inadequate water flow through the heating
system. This may be caused by an obstruction within the pump water lines (filter, pump intakes or internal plumbing), the non-function of the
low-speed mode of the jet pump, or the malfunction of the control thermostat. Once the cause has been identified and corrected, and the
sensor has cooled, reset spa by simply disconnecting power to the spa for thirty seconds.
C. PRESSURE SWITCH: The pressure switch is located inside the control box on the heater, and is designed to prevent heater operation during
a no or low flow condition. If for any reason flow through the heater is reduced or stopped, the pressure switch will trip. If the pressure switch
has detected a no or low flow condition ===== will display for all spa models. The most common causes of inadequate heater flow are a dirty
or clogged filter, obstruction in the plumbing lines, and non-operation of the low speed heat pump. Additionally, the control panel will display
===== for all spa models if the pressure switch senses flow through the heater when the jet pump is not activated. Contact your Authorized Service
Technician if displayed.
D. CONTROL THERMOSTAT: The control thermostat helps regulate the temperature of the water. If for any reason something were to happen to
this device, the
READY icon on the control panel will flash for the TEMPO, RELAY, RHYTHM, SX & TX spa models. Contact your Authorized
Service Technician.
