INSTALLATION
38
In addition, tilting the water heater more than 30° from the vertical during handling will unsettle the refrigerant
gas and compressor lubricating oil. If the water heater has been tilted, it will need one hour to settle before the
power to the water heater can be switched on, otherwise damage to the compressor may result.
All packaging materials must be removed from the water heater prior to its installation. This includes the
removal of the packaging base of the carton from the underside of the water heater.
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.
To maintain the designed performance, air flow and air
discharge from the heat pump, the minimum distances to a wall
or obstruction from the water heater and measured horizontally
along the wall are:
• 25 mm from a wall behind the water heater,
• 350 mm on the left hand side from the air inlet louvre, and
• 1,000 mm on the right hand side from the air outlet louvre.
It is recommended a minimum distance of 900 mm is provided on the left hand side of the water heater to a
wall or obstruction for service access. Refer to the dimensions diagram on page 42.
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.
The heat pump water heater is to be installed at ground or floor level and must stand vertically upright on a
stable base as acceptable to local authorities. 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 barrier should extend at least 100 mm from the
water heater and may be trimmed after two months.
The water heater must not be installed in an area with a corrosive atmosphere where chemicals are stored or
where aerosol propellants are released, as exposure to the corrosive atmosphere may attack the materials
used in the water heater and heat pump system.
FREEZE PROTECTION
The water heater has a freeze protection function built in. When the water heater is placed into Vacation Mode
at the Display Panel and power supply is available to the water heater, either the heat pump operates or the
electric heating unit is used to maintain a minimum tank water temperature above 10°C.
The water heater has NO WARRANTY for freeze damage if power is unavailable at the water heater.
Warning: In areas where the ambient air temperature may fall below 4°C, power must be available to the
water heater at all times.
