COMMISSIONING
29
Note: The heat pump may not turn on after either having just completed a
heating cycle and more hot water is drawn from the water heater or power is
shut down to the compressor, either during or at the end of a heating cycle. The
heat pump will wait until the compressor has cooled down and the conditions
for start up are favourable in order to protect the compressor from damage.
This will be a minimum of forty five (45) minutes and may take up to
ninety (90) minutes from the last heating cycle.
It is important to wait for five (5) minutes after the heat pump has activated to
ensure it continues to operate and is functioning correctly.
Explain to the householder or a responsible officer the functions and operation
of the heat pump water heater. Upon completion of the installation and
commissioning of the water heating system, leave this guide with the
householder or a responsible officer.
TO TURN OFF THE WATER HEATER
If it is necessary to turn off the water heater on completion of the installation,
such as on a building site or where the premises are vacant, then:
Switch off the electrical supply at the isolating switch to the water heater.
Close the cold water isolation valve at the inlet to the water heater.
DIAGNOSTIC FEATURES OF THE HEAT PUMP CONTROLLER
An operating mode monitor is located on the front of the heat pump module and
houses a green and a red LED.
The green LED, marked “NORMAL”,
indicates the current operating mode of the
heat pump water heater and the red LED,
marked “ATTENTION”, indicates a fault
mode.
The green LED will emit either a constant glow or a series of flashes, with a
2 second interval between each series. A series of long green flashes may also
be emitted.
The red LED will emit a series of flashes, with a 2 second interval between
each series, only if there is a particular fault condition with the system.
