Primary Pump
The power to the primary pump for each heat pump is supplied from the water
heater. The maximum pump capacity of the contactor is 9kVA.
An external contactor of suitable rating must be used if a pump exceeds this
capacity and the power supplied from the heat pump terminals must be
connected to the coil of the external contactor.
The heat pump is designed to operate 3 phase pumps. Connect the 3x active
and earth wires to the pump terminals and to the designated terminals inside the
heat pump electrical enclosure.
Phase Rotation is important for correct pump operation.
Tank Sensor Installation
A 10m tank sensor and lead is supplied with the heat pump. Connect the supplied
temperature sensor to the connection terminal on the heat pump marked "Tank
Sensor".
•
Run out the sensor to the nearest storage tank.
•
For RT series tanks, a thermostat well is
supplied which needs to be fitted to the lowest
fitting as shown below.
•
remove the plastic cover from the fitting
located 90° from the water connections on the
storage tank, but do not discard.
•
Insert the sensor all the way into the
thermostat well and fit the plastic cap back
onto the storage tank.
•
To prevent the sensor dislodging from the well, screw the cable to the tank
jacket using a cable clamp.
•
Cable tie the sensor lead, curling up and tying off any excess lead.
•
If longer cable is required, a 20m extension is available.
