Heat Pump Water Heater Installation Guide

Installation Procedure

1. Mounting System
a) Outdoor Mounting. 

Use accessory HPOMK. Lay the unit on its side using 

the cardboard packing as protection. Attach the plastic mounting feet to the 

underside of the unit using the cap screws provided. 

b) Ceiling Installation. 

Use only accessory HPCMK. Mount the ceiling tray 

in the roof space in a suitable location. The unit should then be placed on the 

drip tray and secured in place using the seismic restraints, which should be 

attached to the side of the unit and to the support beams. 

Please note: Adequate access and room for service must be allowed for the 

tradesperson’s safety and to prevent potential property damage. Any damage 

caused to private property due to incorrect installation, including damage 

caused whilst rectifying faults, is not covered under warranty. 

1. 

Ceiling  access  must  be  large  enough  to  allow  the  heat  pump  to  fit 

through it easily. 

2.  A walkway must be installed from the access point to the heat pump. 

3.  The heat pump must be located on a platform at least 2m x 2m and a 

minimum height requirement at heat pump of 1500mm to allow working 

room around the heat pump. 

4.  A light of at least 12W LED must be installed above the heat pump. 

c) Wall Mounting. 

Use accessory HPWMK. Mount wall brackets using level 

onto  concrete  block  wall.  Place  anti-vibration  mounts  supplied  onto  wall 

brackets. Screw up into unit using 4x capscrews (supplied).

d) Closed Garage Installations. 

Cold air leaving the unit must be ducted to 

the outside without loss of air flow. A fresh air supply must also be installed to 

ensure that the correct air flow through the heat pump is maintained.

1. 

Windows are insufficient for this purpose.

2.  Ensure no objects can be placed within 500mm of the heat pump as 

this will reduce its efficiency. 

3.  Allow for drainage of water naturally produced by the cooling coil 

(evaporator) from within the heat pump. 

Adequate access and space for service must 

be allowed for all types of installation
