Set the HEATER knob by rotating it to the desiredtemperature. When the water temperature is lower thanthat set by the HEATER knob, the heater and filter motor/pump will be activated. The heater and filter functions willautomatically turn off when the desired temperature isreached. When the heater is on, the water is also beingfiltered. The heater will also maintain water temperaturein the JETS mode.The Temperature Control is designed to maintain aminimum temperature of approximately 45 - 50 O , itslowest setting. This does not necessarily protect the spafrom freezing. See page 14 for winterizing procedures.Setting the ThermostatYou will notice by the indicator light that the heater ison when the water temperature falls below the desiredtemperature and will turn off when that temperature hasbeen reached.When the spa is not in use, you can set the thermostatto a lower temperature; then, when you wish to use thespa, adjust the HEATER knob to the desired temperature.The water temperature will rise at a rate of about 6 Oper hour with the optional spa cover, foam insulation andskirt panels in place and if the air temperature is 50 O orwarmer. This rate will necessitate a waiting periodbefore using the spa, the length of which will be determinedby the temperature of the water before turning onthe heater. For example, if the water in the spa is keptat about 70 O when the spa is not in use, and the desiredtemperature is 100 O , it will take about 5 hours to heat upOPERATIONsufficiently.Once you have determined the desired setting on thethermostat knob, it is not necessary to change or readjustit again during normal operation unless youdecide on a different setting.The optional spa cover available for your spa will helpcontrol heat loss from the water surface and therebyreduce energy consumption. You can improve the spa’sheat retention by keeping the spa cover in place on thespa while heating the water.Note on Determining Water Temperature:The spa is furnished with a temperature gauge foryour convenience. For the best reference, take watertemperature readings in the HTR/FILTER mode whenthe heater has just turned off; the indicator lamp on thecontrol panel will turn off at this time.TEMPERATURECONTROL KNOBSYSTEMSWITCHACCESSARYSWITCHTHERMOMOTER9
