Page 6: Operational Instructions
Operational Instructions When heating the pool or spa you should check the following items as they are all critical to the proper operation of the heater. 1. WATER FLOW Make sure all pool filters and traps are clean since the unit requires a minimum water flow in order to operate properly. -
Page 7: Time Delay Modes
5. TIME DELAY MODE This heater is equipped with an internal compressor time delay to allow the refrigerant to settle during start-up or restart cycles. When the heater is started the fan will run but the compressor will not start until the 3 to 5 minute delay has passed. The green heating light will be on when the compressor is running. - Page 8 Heat Pump Maintenance & Precautions Air Flow & Access Clearances AIR COIL (on 3 Sides) BASE (CONCRETE OR PREFAB) 1. Make sure the unit has a firm base. The heat pump will produce condensation (water) while in operation. You will notice water coming from the bottom drain ports when the unit is running.
- Page 9 Feeders, Chemicals & Water Balance This heat pump is equipped with the highest marine grade cupronickel alloy heat ex- changer that is designed to resist corrosion from normal pool water. The life and con- dition of the heat exchanger is directly related to the pool water chemical balance and chemical usage techniques.

Freezing Condition Precautions In areas where extended freezing conditions exist, the heater must be plumbed as shown here (and the installation manual), so it can be winterized. Water left inside the heater will freeze and cause damage. This plumbing setup will allow the use of pressur- ized air to clear the heat exchanger of water in preparation for an extended freeze. -
