WARNING
Installation and commissioning
MUST
be performed by authorised persons.
The heat pump
MUST
be installed in accordance with these instructions and all regulatory
requirements which exist in your area including those in relation to manual lifting.
Applicable publications and regulations may include:
•
AS/NZS 3500 National Plumbing and Drainage
•
AS/NZS 3000 Wiring Rules

This appliance is not suitable for use as a domestic spa pool or swimming pool heater.
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 can be installed externally or internally.
The electric heat pump should be placed as close as practicable to the most frequently used hot water outlet point
or points to minimise the delay time for hot water delivery. For installations where the distance between the heat
pump and the outlets is considerable, a flow and return system can be used which minimise 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 air inlet and outlet of the heat pump module
MUST
be away from areas with strong wind and
MUST
be
provided with sufficient clearances as per those shown in the section “Clearances” on page 15
The heat pump
MUST
be connected to an independent AC 415V, 50Hz power supply.
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 storage tank 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 tank
MUST
be installed
with a safe tray (overflow tray) and drain in accordance with AS 3500.4. Ensure the storage tank
DOES NOT
stand on wet surfaces.
Internal Installation
For internal installations the area
MUST
meet the following requirements:
•
Good ventilation to ensure heat pump work properly and efficiently.
If the heat pump is installed internally careful consideration should be taken in regards to positioning and limiting
the effect of unit noise and reverberation during operation.
Condensation
As this heat pump is highly efficient the surrounding air temperature could be cooled by up to 0°C and condensate
formed, the condensate will need to plumbed to a suitable drain.
Drainage
Where property damage can occur as a result of water leakage, the water heater
MUST
be installed with a safe
tray (overflow tray) and drain. Construction, installation and draining of the safe tray
MUST
comply with local
regulatory requirements and. AS/NZS 3500.4 also requires the use of a safe tray for particular situations.
