Electric Heat pumps are heavy and bulky items. Australian States and Territories have a Principal
Occupational Health and Safety (OH&S) Act which contains requirements relating to the handling
of large, bulky or awkward items. Persons installing heat pump systems must be aware of their
responsibilities and be adequately trained and qualified, in accordance with local OH&S requirements..

LOCATION

The electric heat pump MUST BE installed externally.
The electric heat pump should be placed as close as practicable to the most frequently used hot water outlet point
or points to minimize the delay time for hot water delivery. This will usually be the kitchen tap. For installations
where the distance between the heat pump and the outlets is considerable, a flow and return system can be used
which minimize the waiting time for hot water delivery.
It is recommended that all components are installed at ground or floor level. The heat pump MUST BE installed in
a vertically upright position. All components MUST BE accessible without the use of a ladder or scaffold. The unit
MUST NOT be installed in roof spaces.
As the heat pump contains a flammable refrigerant, ensure the installation location complies with the
requirements of AS/NZS 5601.
WARNING
Ensure the pressure and temperature pressure relief (PTR) valve and any access covers have sufficient clearances
and are accessible for service and removal. The information on the rating plates must also be readable.
The heat pump MUST BE installed free-standing on a level and stable base. The cylinder should be mounted on a
concrete base at least 50mm thick or on well-seasoned, evenly spread hardwood slats with a thickness of at least
25mm. Where property damage can occur as a result of water leakage, the storage cylinder MUST BE installed
with a safe tray (overflow tray) and drain in accordance with AS 3500.4. Ensure the storage cylinder DOES NOT
stand on wet surfaces.
The air inlet and outlet of the heat pump module MUST BE away from areas with strong wind and MUST BE be
provided with sufficient clearances as per those shown in the section '' on page 12
The heat pump must be connected to an independent AC 240 V, 50 Hz power supply.
