Cleaning
Toensureoptimum performanceof theheatpump, followthese recommendations:
- Backwash the filter of the pool on a regular basis in order to ensure proper flow rate
throughthepoolheater;
-Keepthesurfaces of thecoilcleanand freeofanyobstructionsuch aspapers,leavesor
otherdebris;
- Carefully clean the unit using a soft, non abrasive and bleach free cleaner, and rinse
usingagardenhose withoutthenozzle;
- Check the drainage holes of the base of the unit to make sure that they are clean and
unobstructed. (Thispreventswaterfrom accumulatinginthe heatpump.)
Winterizing (Cupro-nickel heat exchanger)
Ifyouclosetheswimmingpoolduring thewinterseason, it isessentialtodrainthe unit in
order to prevent the formation of ice in the condenser (water section). To winterize the heat
pump,youmust:
1.Stopthe unit;
2.Shut offthebreaker ofthe heatpump electricalsupply line;
3.Disconnectthewater intletandoutlet connections (See “WaterDeviation”for details.);
4.Freelyflush thecondenser withtapwater.Completely drainthesystem usingair pres-
sure or vaccum system. We do not recommand putting anti-freeze into the heat pump
pipes,but ifyou chose toput some, make sure itis compatiblewith copper, otherwise, it
woulddo moredamage tothe condenser thansmall quantityof icewould;
5.If theheat pumpis leftoutsideduringwinter,protect itwith awaterproof cover.
