System Start-Up

1. Unplug the power cord (120-volt system only) or turn the electrical power “OFF” at the service or breaker panel (120 or 240 volt permanently connected units.)
2. Open all WATER shut-off valves.
3. For spas equipped with a hose bib or drain valve, make sure that it has been closed.
4. For spas equipped with in-line or pressure water filters, make sure that the filter nut, housing drain plug, and air relief valve are closed and tight.
5. Using a standard water hose, fill the spa with fresh tap water to the level recommended by the spa manufacturer.
6. Inspect all plumbing connections and lines for any sign of water leaks.
7. Close all AIR control valves.
   • WARNING: Do not confuse with WATER shut-off valves.
8. Plug the unit into the proper outlet (120-volt system) or turn on the breaker at the electrical service panel (240-volt system).
9. When the system is first started (or any time power is reset) it will go through a series of diagnostic checks, displaying various information on the display, and finally ending with the spaside panel reading “PR” meaning Priming Mode.
10. During Priming Mode, press “Jets” button(s) repeatedly and be sure all pumps are free of air.
11. On systems with a pressure filter, bleed off the trapped air by opening the Air-Relief valve. You will notice a steady flow of water when the air has been bled completely.
12. If equipped, switch the “AIR BLOWER” on to verify that it is working, then switch it off.
13. If equipped, switch the “LIGHT” on to verify that it is working, then switch it off.
14. If equipped, switch the “AUXILIARY PUMP” on to verify that it is working, allow to run until all air is evacuated from the plumbing system, then switch it off.
15. Adjust temperature to the desired set point for comfortable use of the spa. The pump low speed and heater will activate until the set point has been reached.

Heater Start-Up Sequence
The HydroQuip heater goes through a testing phase every time it starts up to assure that there is adequate water flow.

1. Prior to heating, the pump will run for at least 2 minutes and verify that sensors are within specifications.
2. The heater turns on for 6.5 to 18 seconds. At this point, the heat indicator on the panel is “solid”. During this time the spa side panel is not immediately responsive.
3. The heater turns off for 90 seconds, checking for adequate water flow in the heater. At this point, the heat indicator on the spa side panel may appear to “flicker” or “dim”.
4. After adequate water flow has been verified, the heat indicator on the spaside panel returns to “solid” and the spa will heat to set temperature.

Filtration Programming

• The first preset filter cycle begins 6 minutes after the spa is powered up. The second preset filter cycle begins 12 hours later. Filter duration is programmable for 2, 4, 6, or 8 hours or for continuous filtration (indicated by fc ). mTo program, press “Warm” or Cool” then “Jets 1.” Press “Warm” or “Cool” to adjust the number of hours of filtration. Press “Jets 1” to exit programming.
• For non-circulation pump systems, low-speed pump 1 and the ozone generator (if installed) run during filtration.
• For 24 hour circulation systems, the circ pump and the ozone generator (if installed) run 24 hours. In hot environments, the circulation pump may turn off for 30 minute periods, except during filter cycles.
• For non-24 hour circulation pump systems, the circ pump and ozone generator (if installed) run during filtration (and may also run automatically at other times).
• At the beginning of each filter cycle all other pumps and blowers will run briefly to purge the plumbing to prevent water from becoming stale.
• IMPORTANT – Heater pump must provide a minimum flow of 23 GPM through the

Spa Light
Your control kit may include one of the 2 different light bulbs shown below. Both Light bulb styles will plug into your existing socket.
Your control may also include a new light harness and plug but this harness is not required if your existing unit looks the same.

To replace your spa light bulb, locate the light fitting and clear away any insulating or foam material to allow you to access the rear of the fitting.

Important Note : Do NOT loosen or remove the large light fitting or nut, the bulb replacement can be completed by simply removing the rear reflector.

Deluxe LED Light

• The LED bulb is installed by removing the white reflector by turning it counter-clockwise and removing from the fitting body.
• Remove the existing bulb and replace with the LED bulb and then replace the reflector onto the fitting body.
• The LED light includes multiple LED’s to allow you to choose from 7 different colors, a color wheel or strobe function.
• To operate and change the light colors, simply push the light button on the spaside control On and Off until you find your preferred color.

Standard Light

• The light bulb is removed by simply turning the socket counter-clockwise and then removing from the white reflector.
• The operation of this bulb is a simple On or Off function by pushing the appropriate button on the spaside control.
• A colored lens can be attached to the light body as shown to change the color to Blue or Red.

Please refer to page 16 for the appropriate light operation details.

Operation Considerations

The following describes situations you may encounter and situations to be aware of.

Warm Weather Conditions
Since your spa will normally be expected to maintain warm to hot water ready for use, a great deal of attention has been directed to the energy conservation detail of insulation to keep electrical cost down. Energy conservation efficiency may be achieved by extensive insulation of the spa cabinet, plumbing, spa shell and in some climates full foam insulation may have been provided. This energy conservation feature may cause an inconvenience during warmer times of the year. During warm periods of the year, the temperature within the equipment compartment can elevate to a point that the pump will automatically turn off for a short amount of time (15-30 minutes) to allow the pump to cool down before automatically restarting. This cool down feature will not harm your spa, but serves only to protect the pump from damage ad as and indicator that it is too hot. To minimize this occurrence, refrain from using your Hydrotherapy Jets for prolonged periods of time during warm seasons. The jet pump chosen for your spa has been specifically sized for maximum performance and your Hydrotherapy enjoyment.

Filtration System
Please refer to your Spa Manufactures Owner’s Manual regarding the operation, maintenance and cleaning of your filtration system.

IMPORTANT – Heater pump must provide a minimum flow of 23 GPM through heater.

Winterizing
When freezing weather and/or power losses are expected, contact your local spa dealer for freeze protection or winterizing recommendations for both the spa and the equipment system. Freeze related damage is not covered by the warranty.

Chemical Water Treatment

• Your dealer is familiar with local water conditions and which chemicals are compatible with and designed specifically for your spa. This is the best person to advise you on proper water quality management. The one thing you can do to insure years of trouble free equipment operations is to maintain proper water chemistry.
• Two basic goals of the chemical water treatment are sanitizing and balancing the water. Sanitizing simply means keeping the water free from microorganisms including algae, bacteria and viruses. The current most popular chemicals for sanitizing include chlorine, bromine and ozone.
• Balancing water means establishing a balance among pH, total alkalinity and total hardness. Water that is unbalanced can corrode the spa and it’s support equipment or leave deposits of minerals. Properly balanced water is essential to allow the sanitizing chemical to work effectively. There are numerous chemical additives to help you in controlling pH, total hardness and alkalinity. Never use softened water when filling you spa. Softened water is extremely corrosive to the metal parts of the spa equipment and may lead to an unforeseen failure. Sometimes, despite your most diligent efforts, your water may become to far out of balance to be managed chemically. At this point it is probably better to drain and clean the spa and start over with fresh water. Equipment failure caused be improper water chemistry will not be covered under warranty. Saltwater purification systems can potentially damage your equipment. Any related failures will not be covered under warranty.

Testing the Sensor Set

IMPORTANT: For the following set of instruction, the power must be off when plugging in or unplugging sensors.

1. Check sensor wires for cracks or damage that may indicate the presence of a rodent.
2. Inspect connections of both sensors on the circuit board. The plugs must be clean.
3. If the spaside has the error message of SA or Sb, this is an indication of a faulty sensor or possibly a faulty circuit board.
4. With the power off to the spa, unplug the two sensors from the circuit board and exchange their positions (i.e., plug the one that was in the “Sen. A jack into the “Sen. B jack and vice versa).
5. Power up the spa, if the error message did not change (i.g. original error message was SA and still displays SA) this is an indication of a faulty circuit board. If the error message changed (i.g., original error message was SA and now displays Sb) replace the sensor in the corresponding plug on the circuit board.
6. When replacing sensors, please keep in mind that the heater assembly will contain water pressure even with the spa’s power off. Close available slice valves and proceed with caution not to allow water on the surrounding electronics.
