ABOUT YOUR WATER HEATER
5
MAINS PRESSURE
The water heater is designed to operate at mains pressure by connecting directly to the mains water supply.
If the mains supply pressure in your area exceeds that
shown on page
20, a pressure limiting valve must be
fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
A minimum water supply pressure of 200 kPa is required to enable the heat pump circulator and heat pump
system to operate effectively.
HOW HOT SHOULD THE WATER BE?
The system controls (compressor, evaporator and fan) will operate
until a water temperature of 60°C is reached. If the ambient air
temperature is outside of the heat pump
‟s operating range, the
water temperature is boosted automatically to 70°C by the
thermostatically controlled booster electric heating unit, if heating is
required
To meet the requirements of the National Plumbing Standard the
temperature of the stored water must not be below 60°C.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater can deliver water at temperatures which can
cause scalding. Check the water temperature before use, such as
when entering a shower or filling a bath or basin, to ensure it is
suitable for the application and will not cause scald injury.
We recommend and it may also be required by regulations that an
approved temperature limiting device be fitted into the hot water
pipe work to the bathroom and ensuite when this water heater is
installed. This will keep the water temperature below 50°C at the
bathroom and ensuite. The risk of scald injury will be reduced and
still allow hotter water to the kitchen and laundry.
TEMPERATURE ADJUSTMENT
The thermostats controlling the heat pump and the booster heating unit are factory set and not adjustable.
WARNING
This water heater is only intended to be operated by persons who have the experience or the knowledge and
the capabilities to do so. This water heater is not intended to be operated by persons with reduced physical,
sensory or mental capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do
not interfere with the water heater.
This water heater uses 240 V AC electrical power for operation of the control systems and the electrically
operated components. The removal of the access cover(s) will expose 240 volt wiring. They must only be
removed by a qualified person.
Do not use
aerosols, stain removers and household chemicals
near the water heater whilst it is
working. Gases from some aerosol sprays, stain removers and household chemicals are corrosive to the
materials used in the heat pump system.
Do not store swimming pool chemicals, household cleaners, etc., near the water heater.
Ensure the air flow, air inlet louvres and outlet grille are not obstructed in any way at any time.
