The Swimming Pool Heat Pumps exclusive rated flow titanium heat exchanger requires no special plumbing
arrangements except bypass (please set the flow rate according to the nameplate). The water pressure drop is less
than 10kPa at max.
Flow rate: Since there is no residual heat or flame Temperatures, the unit does not need copper heat sink piping.
PVC pipe can be run straight into the unit.
Location: Connect the unit in the pool pump discharge (return) line downstream of all filter and pool pumps, and
upstream of any chlorinators, ozonators or chemical pumps.
Standard model have slip glue fittings which accept 40 mm PVC pipe for connection to the pool or spa filtration
piping. By using a 50 NB to 40NB you can plumb 40NB.
Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to allow easy draining of unit
for winterizing and to provide easier access should servicing be required.
5.10 Electrical Connection
IMPORTANT: Always use a qualified Electrician to perform any electrical work. A licensed electrician must read the
information before connecting.
Ensure the power cable and circuit breaker are of a suitable size for the heater being installed. Also check that there
is adequate voltage and current available at the heater connection to run the unit.
Voltage range should be 220-230 volts for single phase, and 380-400 volts for 3 phase units. Voltage ranges outside
these parameters will cause heater damage and void your warranty.
1.
Ensure power is disconnected during installation or service.
2.
Always comply with the national and local electrical codes and standards.
3.
Ensure electrical cable size is adequate for heater requirements at the installation location.
4.
The heater must be equipped with a circuit breaker and isolation device.
5.
Circuit breaker must be installed between the heater and the water circulation pump if the water pump is
hard-wired into the heater. Please note recommended circuit breaker sizes make no allowance for a water
pump hard wired into the heater.
6.
The unit must be well earthed. Remove the front panel to access the electrical connection terminals of the
heater. The electrical wiring diagram is affixed to the inside of the front panel.
