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. This will usually be the kitchen tap. For installations
where the distance between the heat pump and the outlets is considerable, a ow 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 oor level with consideration for easy service,
repair or replacement access.. 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.
WARNING
Ensure the location complies with the requirements of AS/NZS 60335�2�40 & AS/NZS 5149�
The air inlet and outlet of the heat pump module MUST be away from areas with strong wind and MUST be
provided with sufcient clearances as per those shown in the section ‘Clearances’ on page 14.
The heat pump MUST be connected to an independent AC 240 V, 50 Hz power supply.
Ensure the pressure and temperature pressure relief (PTR) valve and any access covers have sufcient 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 (overow tray) and drain in accordance with AS 3500.4. Ensure the storage cylinder DOES NOT
stand on wet surfaces.
Internal Installation
For internal installations the area MUST meet the following requirements:
•
Minimum room volume of 55m
3
per unit.
•
Good Ventilation (i.e minimum 280 L/s per unit)
•
Away from any ignition sources or corrosive environments.
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 efcient, the surrounding air temperature could be cooled by up to 4°C and condensate
formed, the condensate outlet will need to be plumbed to a suitable drain.
