Very important!
To protect the heat pump, construct a roof over it which overhangs the heat pump by 300 mm all
round. The roof should be 150 mm above the heat pump. This will protect the equipment from rain
and snow.
Employ a qualified electrician for permanent electrical installation of the heat pump to the
electricity supply.
Short-circuit protection for type 88 10A and for type 120 10A. 380-415V 3~.
The heat pump must be installed with an on-off switch and an earth fault relay.
When making the electrical installation, check that the electricity of the heat pump has the correct
phase rotation. There is a black rubber plug on the front side of the heat pump. Remove it and
check that the red and green lamps on the circuit board give light. If so, the installation is correct. If
the red and green lamps do not give light, 2 of 3 phases have to be shifted. Shift and check again.
Put back the plug when the installation is completed.
Only an accredited refrigeration company may carry out work on the refrigeration circuit.
Operation of types 88 and 120
For the heat pump to work, the pool filter system must be running.
- When the pool water is circulating, switch on the power to the heat pump.
- On the heat pump there is an adjustable electronic thermostat graduated 0-10, which is used to
increase the pool water temperature from 0 to maximum. Set the knob to 10. Within about three
minutes the heat pump compressor starts. When the pool water reaches the desired
temperature, turn the knob back until the fan stops.
- At the beginning of the season, when the water in the pool is cold, the heat pump will run
continuously for a long time before the pool reaches the correct temperature. When the pool
water has reached the correct temperature, the heat pump stops automatically and starts
again when necessary.
- For a higher water temperature, increase the thermostat setting by turning the knob clockwise.
- For a lower water temperature, reduce the thermostat setting by turning the knob anticlockwise.
- The running time of the heat pump depends on the temperature of the water and the air, on the
air humidity, sunlight, wind, etc., and may vary from day to day.
- During the summer, the evaporator at the heat pump fan will need cleaning. A vacuum cleaner
may be used.
- Switch off the heat pump when backwashing, or if the filter pump is off.
Winter and the risk of frost
Before winter and when there is a risk of frost, all water must be drained from the heat pump. If
there is any water left in the heat exchanger it may suffer frost damage.
- Switch off the power to the heat pump and disconnect the two union couplings on the heat
exchanger.
- Unscrew the heat exchanger drain plug on the side of the heat pump and remove any water
that may still be in the heat exchanger.
- Cover the heat pump in winter and protect it from rain and snow, but ensure that there is good
ventilation to prevent the formation of condensation. The heat pump can withstand the cold if
no water is left in it.
- Before the summer, and before starting the heat pump, remove from the air intake any leaves,
pine needles and other dirt which may obstruct circulation and so reduce the efficiency of the
heat pump.
- To clean the heat pump, wipe it down with soapy water.
