INSTALLATION
16
WATER HEATER LOCATION
The water heater is suitable for outdoor installation only. The water heater should be installed close to the
most frequently used outlet and its position chosen with noise, safety and service in mind. Make sure people
(particularly children) will not accidentally touch the air inlet and outlet louvres and that they are clear of
obstructions and shrubbery.
It is advisable to install the water heater away from
bedroom or living room windows as the system controls
can generate a level of noise whilst they are operating.
Consider the location in relation to neighbours‟ bedrooms
and living room windows.
Clearance must be allowed for servicing of the water
heater. The water heater must be accessible without the
use of a ladder or scaffold. Make sure the temperature
pressure relief valve lever is accessible and the top and
front cover, air inlet and outlet louvres, system controls
and thermostat can be removed for service.
You must be able to read the information on the rating
plate. If possible leave headroom of one water heater
height so the anode can be inspected or replaced.
Remember you may have to remove the entire water
heater later for servicing.
It is recommended the heat pump water heater be installed at ground or floor level and must stand vertically
upright, supported by a level slab or solid base. The base of the water heater is made of corrosion resistant
material, and it may be placed directly in contact with the supporting surface. It is not necessary to allow for
free air circulation under the base of the water heater.
Note:
The water heater should not be placed in direct contact with a concrete surface that is less than two
months old and not fully cured as this may attack the metal coating of the water heater base. A moisture
barrier should be used between the two surfaces in this instance.
The water heater must be installed with a clearance of at least 100 mm from a wall. A clearance of at least
300 mm is required perpendicular from both the air inlet and outlet louvres to any wall or obstruction. Refer to
the
dimensions diagram
on page 20.
The water heater must not be installed in an area with a corrosive atmosphere where chemicals are stored or
where aerosol propellants are released. Remember the air may be safe to breathe, but the chemicals may
attack the materials used in the heat pump system.
SAFE TRAY
Where damage to property can occur in the event of the water heater leaking, the water heater must be
installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements.
MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table below, an approved pressure
limiting valve is required and should be fitted as shown in the installation diagram
(refer to diagram on
