The Electronic Components
The Spa Pack is the computer that controls the spa functions. Not only does the pack respond to user commands a button on the
topside control is pressed, it’s also programmed to automatically take care of many of the maintenance and safety features so you don’t
have to. For example, when it’s time for the ltration cycle to begin, the spa pack turns the pumps on automatically to circulate the water
and automatically turns them o when the cycle is complete.
Diagnostic Testing
The spa pack is programmed to run and retain the results of diagnostic testing, ensuring your spa is operating eciently. If
a problem is detected, an error message will be displayed on your topside control making you aware that your spa requires
attention. Error messages can often be resolved simply by turning the GFCI “OFF” for 30 minutes and turning it back “ON”,
known as a System Reset. If an error message is displayed after resetting the system, please refer to the troubleshooting
guide in this manual or call your local dealer for additional assistance. ALWAYS turn the GFCI “o” before performing service
or repairs.
The Topside Control is like the keyboard for a computer. Pressing a button on the topside control relays a command to the spa pack
to perform a specic function. Water temperature, ltration cycles, lighting, energy saving features and jet functions are all controlled
by pressing buttons on the topside control. In addition to controlling the functions, the topside control also relays diagnostic and error
messages to alert you if a problem is detected.
Primary and User Controlled Functions
During heating, ltration and other maintenance cycles some of the buttons on the topside control are disabled. For example,
if the water temperature falls below the programmed temperature allowance while you’re using the spa, a heating cycle will
begin automatically and the water will circulate on low speed until the correct temperature is reached. Pressing the “pump”
button will not turn the pump o or change the circulation speed when the heater is on. Because the pack is programmed to
prioritize safety and maintenance functions, any user controlled functions that interfere are disabled until they are completed.
The Spa Heater warms the water. Once your temperature settings have been programmed your water temperature will be maintained
automatically. When the water temperature falls below the temperature allowance, the spa pack will turn the heater and pump(s) on and
o automatically when the correct temperature is reached.
High Water Temperatures During Warm Weather
During warm summer months, it’s a good idea to reduce your water temperature settings. Spas are designed to retain
heat, and aren’t equipped to cool the water. When the ambient temperature is high and it doesn’t get cold enough for your
water temperature to fall, your water temperature may be higher than the temperature you programmed. Reducing your
programmed temperature not only resolves this, it also conserves energy and reduces operating costs. If you want to reduce
the water temperature quickly, remove the cover for a short time allowing some of the heat to escape or drain some of the
warm water from your spa and replace it with cool water. If you drain water from your spa, turn the GFCI “o” and follow the
instructions when relling it and balancing your water chemistry.
The Spa Pump(s) push the water through the plumbing lines and into the spa. The pump(s) are turned on and o by pressing the
button(s) on the topside controls. The number and speed of the pumps varies by spa model.
Air in the Plumbing Lines and Pumps
The pumps are designed to pump water, not air. Air trapped the pump or the plumbing lines prevents circulation of the water.
Letting your pumps run with an air lock will instantly destroy the pump(s). Following the manufacturer’s instructions to ll
your spa properly and soaking new lters for 30 minutes before powering the spa on will help prevent air locks. If you hear
a “humming” sound, if the jets don’t work or if the jets only work in part of the spa when you press the jets button, it is likely
you have an air lock and need to prime the pump. Never allow a pump that is not primed to run for more than 2 minutes.
Using the Air Release Screw to Bleed Air from the Pumps
1. Insert a screw driver into the air release screw located on the pump
2. Loosen the air release screw. Turn counter clockwise until water begins to trickle. DO NOT REMOVE SCREW!
3. When water is trickling steadily, turn the screw clockwise to tighten the screw and stop the ow of water.
