Winterising Procedure

!
VITAL
If the pool heat pump is stored in a place where the temperature drops below
the freezing point of 0˚C (32°F); it is mandatory that the water accumulated in
the pool heat pump be drained completely before freezing weather prevails.
Improper winterizing may damage the pool heat pump and will void the warranty.
• Turn the pool heat pump "OFF".
• Turn the pool heat pump breaker "OFF".
The water piping MUST be disconnected to drain the pool heat pump's heat
•
exchanger in preparation for winter.
• Once the piping is disconnected, the pool heat pump's heat exchanger MUST
be emptied; the use of a water vacuum cleaner is strongly recommended or if
you do not have this tool you may tilt the unit (75˚) until all the water is out.
• It is recommended that pool heat pump's heat exchanger is rinsed out with a
gentle water spray at the inlet and outlet water connections of the pool heat
pump and then drain the heat exchanger again.
• With the help of 2 pool return winter plugs, block the water Inlet and Outlet
connections to prevent access by vermin.
• Clean the drainage holes located at the bottom of the base of the unit.
• Unit may be covered for the winter.
• It is also possible to fill the heat exchanger with pool anti-freeze, but ensure that
the antifreeze contains an elevated pH to prevent corrosion. This is optional
and requires appropriate hardware.

GENERAL SAFETY INSTRUCTIONS

DO NOT DEPRIVE YOUR POOL HEAT PUMP OF WATER FLOW FOR MORE
THAN 24 HOURS WITHOUT DRAINING IT. Make sure you leave the bypass
valves as shown in Figure 1.
At the end of each season, when the pool heat pump is no longer in use, and
proper pool water chemistry is not maintained, it should be disconnected from the
water line and drained to prevent any possible corrosion or damage to the pool
heat pump. Refer to Figure 1 below or winterising procedure (page 24).
