INTERNAL AUTOMATIC BYPASS The heat pump in equipped with a internal "Automatic Bypass" valve. A variable rate spring valve is used to regulate the water flow through the heat exchanger. Steady flow will be delivered over a wide range of flow rates. This automatic valve can handle a maximum flow rate of 90 gallons per minute. The automatic valve will compensate for flow loss due to normal filter debris accumulation or changes if flow due to valving and other conditions. See chlorinator IN placement guidelines.

CAUTION The chemical resistant check valve and loop must be installed with all types of chlorinators to prevent chlorine migration to the heater. The loop should extend at least 8 inches above the chlorinator top. The chemical resistant check valve should be placed on the pipe leading "up" to the chlorinator. Therefore, the weight of the water above the check valve will hold it closed even if the spring is weak or damaged. Mount it as low as possible. Be sure to keep the chlorinator, pump and filter lid o-rings lubricated with silicone grease to insure a good seal. If it looses its seal, it will allow the chlorine to migrate to the heater when the system shuts off. The loss of vacuum allows reverse flow. 19 8" 2 LB CHEMICAL RESISTANT CHECK VALVE Part# 888-018 LOOP ABOVE CHLORI- NATOR FROM HEATER TO POOL EXCESSIVE FLOW BYPASS MANIFOLD FOR LARGE 2 H.P.
