Winterising Procedure

!
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.
