MAINTENANCE
Before performing any maintenance on the heat pump you must turn off the breaker of
the electrical supply line.
Cleaning
To ensure optimum performance of the heat pump, follow these recommendations:
- Backwash the filter of the pool on a regular basis in order to ensure proper flow rate
through the pool heater;
- Keep the surfaces of the coil clean and free of any obstruction such as papers, leaves or
other debris;
- Carefully clean the unit using a soft, non abrasive and bleach free cleaner, and rinse
using a garden hose without the nozzle;
- Check the drainage holes of the base of the unit to make sure that they are clean and
unobstructed. (This prevents water from accumulating in the heat pump.)
Winterizing (Cupro-nickel heat exchanger)
If you close the swimming pool during the winter season, it is essential to drain the unit in
order to prevent the formation of ice in the condenser (water section). To winterize the heat
pump, you must :
1. Stop the unit;
2. Shut off the breaker of the heat pump electrical supply line;
3. Disconnect the water intlet and outlet connections (See “Water Deviation” for details.);
4. Freely flush the condenser with tap water. Completely drain the system using air pres-
sure or vaccum system. We do not recommand putting anti-freeze into the heat pump
pipes, but if you chose to put some, make sure it is compatible with copper, otherwise, it
would do more damage to the condenser than small quantity of ice would;
5. If the heat pump is left outside during winter, protect it with a waterproof cover.
Winterizing (Titanium heat exchanger)
If you close the swimming pool during the winter season, it is essential to drain the unit in
order to prevent the formation of ice in the condenser (water section). To winterize the heat
pump, you must :
1. Stop the unit;
2. Shut off the breaker of the heat pump electrical supply line;
3. Loseen the bypass valves (photo A) and let the water drain out (See “Water Deriva
tion” for details.);
4. Unscrew the small cap (photo B) with the help of two wrenches (photo C) and freely
flush the condenser with tap water. Completely drain the system using air pressure or
vaccum system. Store the small cap during winter.
5. Block the opening of either the water inlet or outlet pipe (photo D) with your hand and
blow air into the pipe not covered by your hand to flush out the water completely. If the heat
pump is left outside during winter, cover it with a waterproof cover.
