POOL WATER FLOW SWITCH
A pool water loop ow switch is factory-installed in the PoolPak™ unit. The ow switch is factory-calibrated and should
not be adjusted. If the ow switch contacts are not closed when water is owing through the PoolPak™ unit, there may
be insufcient water ow. The PoolPak™ unit can be operated with inadequate water ow; however, the PoolPak™
System will not go into a water-heating mode until the water ow switch contacts are closed by sufcient water ow.
Refer to Table 3-2 for design pool water ow.
POOL WATER PIPING COMPOSITION
Pipe must be a suitable material such as CPVC Schedule 80 plastic pipe. PVC, copper, iron or steel pipe is NOT suitable.
It must be kept free of all foreign matter.
FREEZE PROTECTION
Any pool water piping (eld-supplied) exposed to outdoor ambient air temperatures must be protected against freezing.
Wrap pipes with electric heat tape (follow manufacturer’s instructions) controlled by an automatic thermostat and set at a
minimum of 35°F. Insulate all piping. Insulation must be sealed at all seams.
NOTE
Power for the eld-installed heat tape must be supplied external to the PoolPak unit.
