Antifreeze protection in winter PP07
Ambient temperature or
water inlet temperature is
too low
1. The rst grade antifreeze
protection condition: when
6°C<T1 water in temperature
<10°C and T5 ambient
temperature 3°C, water pump
should operate 30 minutes, then
stop 30 minutes in this cycle.
When ambient temperature
T5>5°C or T1 water in
temperature 15°C, water pump
stop operating will activate the
antifreeze protection.
2. The second grade antifreeze
protection condition; T1 water in
temperature 6°C and T5 2°C, it
goes into the second antifreeze
protection, the heat pump
should go into Smart mode for
water heating will to T1>15°C or
T5>7°C.
Remarks: The water pump and heat
pump must be turned ON or in
standby status.

Troubleshooting
Maintenance
1. You should check the water supply system regularly to ensure correct water ow and that
air is entering the system. This may result in a reduction in the performance and reliability of
heat pump unit.
2. Clean your pool and ltration system regularly to avoid damage to the heat pump.
3. In areas subject to sub zero temperatures, the heat pump must be de-commissioned during
the winter months. To do this, the drainage plug must be removed from the heat pump to
allow water to drain from the heat exchanger. Once the water has been drained from the
unit, the drainage plug can be re-installed for use of the heat pump.
4. For optimum performance the ow rate must match specications provided by the
manufacturer.
5. Place the winter cover on the heat pump while the unit is unused during Winter.
6. The air drawn into the heat pump is cooled by the operation of the heat pump for heating
the pool water, which may cause condensation on the ns of the evaporator. The amount of
condensation may be as much as several liters per hour at high relative humidity.
