INSTALLATION
THIS APPLIANCE MUST BE INSTALLED BY AN AUTHORISED PERSON. Refer to heater data
plate for specifications of operating voltage and current and water pressure.
This appliance must be installed in accordance with local regulations and the National Wiring Rules.
A multi-pole isolating switch must be installed that operates in all live conductors so that it isolates the
entire equipment from the supply.
FLOW RATES
The Astral Pool Heater requires a flow rate of approx 150 to 550 litres per minute. For flow rates in
excess of 250 litres per minute, an external by-pass valve must be fitted. When setting up the unit, the
water balancing valve should be adjusted while the heat pump is operating. Using the gauge fitted on the
front of the unit, adjust water flow until reading is approximately 1.5MPa. With the unit turned off, the
gauge should settle at approximately 0.8MPa. If these readings are not achieved, please contact Astral
Pool service.
WATER CONNECTIONS
Where the heat pump is installed in the filtration circuit, the heater should always be installed after the
pump and filter. The water connections are located on the right hand side of the heater. The inlet and
outlet are clearly marked. Water connections supplied are for 50mm PVC glue in plumbing.
All automatic sanitising devices must be installed after the heater and in such a way that the sanitiser
cannot enter the heater without first mixing with the water in the pool or spa. Sanitisers that are
connected prior to the heater will void heater warranty.
The Astral Pool Heat Pump Pool Heater is only suitable for outdoor installation.
Note: These units are supplied with an internal water pressure switch mounted on the lower heat
exchange. This must be adjusted as part of the installation / commissioning.
