ABOUT YOUR 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.
HOW HOT SHOULD THE WATER BE?
The system controls (compressor, evaporator and fan) will operate
until a water temperature of 60°C to 70°C is reached, depending
upon the Hot Water Temperature Set Point. If the ambient air
temperature is outside of the heat pump's operating range, the
water temperature is boosted automatically to the Hot Water
Temperature Set Point by the electric heating unit, if heating is
required.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
Warning: This water heater can deliver hot water at
temperatures up to 70°C, sufficiently hot to cause severe scalding.
Water at this temperature may have been plumbed to fixtures where
water hotter than 50°C is allowed, such as the kitchen and laundry.
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 Hot Water Temperature Set Point for the heat pump and electric heating unit is adjustable from 60°C to
70°C. This is the temperature to which the Heat Pump and electric heating unit will heat the water and then
"Hot Water Temperature Set Point"
cut out. Refer to
DISPLAY PANEL
The water heater has a Display Panel to indicate the status of the water heater. The Display Panel also
allows the user to select the Hot Water Temperature Set Point. Refer to
TIMER CONTROL
It may be desirable for the water heater not to operate between certain hours, such as during the peak
period when connected to a Time of Use electricity supply due to a more expensive tariff rate applying.
An external timer will affect the operating times of both the heat pump circuit and the electric heating unit.
Consideration must be given to the time allowed to heat up the water in the water heater in cold conditions.
Note: If there is a risk of freezing conditions, the electrical supply to the water heater should not be switched
off, otherwise damage could result. Refer to
PRECAUTIONS
The water heater must be maintained in accordance with the Owner's Guide and Installation Instructions.
"Maintenance Requirements"
Refer to
If this water heater is to be used where an uninterrupted hot water supply is necessary for your application or
business you should ensure that you have back-up redundancy within the hot water system design. This
should ensure the continuity of hot water supply in the event that this water heater were to become
inoperable for any reason. We recommend you seek advice from your plumber or specifier about your needs
and building back-up redundancy into your hot water supply system.
