Heat Pump Water Heater Installation Guide
Apply 9cc of thermal paste (supplied with Tank Sensor) to the back of the tank
sensor mount and place it in the drilled hole against the inside layer of the cylinder.
Adjust the foam core supplied such that when inserted with the pocket into
the hole it sticks out by at least 10mm. Insert the tank sensor foam core, and
then attach the tank sensor cover using the screws provided. Pilot holes of
3.2mm (1/8”) diameter will need to be drilled for these screws. Plug the tank
sensor into the header marked J4 or Ttl on
the circuit board of the HWB module.

to the diagram below. The appliance must be installed in accordance with
AS/NZS 3000:2000. A means for disconnection must be incorporated in the
