A manual bypass valve should be installed across the heater when the pump flow exceeds 120 GPM. See instructions below for setting of the manual bypass. Make sure that the outlet plumbing from the heater con- tains no shut-off valves or other flow restrictions that could prevent flow through the heater (except as noted below). To switch flow between the pool and spa, use a diverter valve. Do not use any valve that can shut off the flow.

Do not use a shut-off valve to isolate the heater unless it is below the level of the pool or spa.

Install a check valve if there is a possibility of back-siphon- ing through the heater when the pump is off.

NOTICE: Improper operation of chemical feeders can cause severe damage to the heater which is not covered by the warranty. Either equip chemical feeders with an anti-siphon device to prevent chemicals from siphoning into the heater if the pump shuts off, or install the chemical feeder down- stream of the heater (see “Water Chemistry,” Page 17). NOTICE: If the heater is plumbed in backwards, it will cycle continuously. Make sure piping from filter is not reversed when installing heater.

WATER PIPING

Connect the heater directly to 2” PVC pipe, using the inte- gral unions provided. Heat sinks are not required. The low thermal mass of the heater will prevent overheating of the piping connected to the heater even if the pump shuts down unexpectedly.
