7. MAINTENANCE

Disconnect the power to the heat pump before any inspection, cleaning or service.

1. Winterising your heat pump:

Winterising is required in conditions where any water inside the heater can drop below 0°C. In this situation, if not carried out, severe damage is likely to occur to the Davey heat pump.

a. Turn off the circuit breaker, or isolation switch; b. Drain the Davey heat pump. Loosen all water connections; c. Rinse the interior of the heat exchanger cylinder with a stream of tap water for about 15 minutes to remove any chlorine residue that could cause damage to the heat exchanger. d. Tilt the unit towards the back to remove all water from the unit.

e. Block water inlet and outlet with a cloth or plastic to prevent mice, or other animals from entering the unit.

WARNING: All water connections to the pool should be disconnected for winter to allow complete drainage of the Davey heat pump. The winterising must be done before air temperatures reach freezing point.

WARNING: The Davey heat pump should never be tilted more than 30-35º, even during transportation. Should this occur, allow the Davey heat pump to sit for

4 hours before turning on.
