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 switches to the water
heater.
Close the cold water isolation valve at the inlet to the water heater.
Note:
The freeze protection system will be rendered inoperable if electrical
power is not available at the water heater.
Damage caused by freezing due to the unavailability of power at the water
heater is not covered by the manufacturer‟s warranty (refer to “Terms Of
The Warranty And Exclusions To It” on page 31).
If the power has been switched off to the water heater and there is a risk of
freezing, then it is necessary to drain the water heater (refer to “Draining
The Water Heater” section in the Owner‟s Guide and Installation
Instructions supplied with the storage tank).
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
(with the red LED off) of the heat pump
water heater and the red LED, marked
“ATTENTION”, may indicate a
potential fault mode.
The green LED will emit either a constant glow or a series of flashes, with a
2 second interval between each series. The green LED may also emit a series
of flashes in conjunction with the red LED to indicate a particular fault condition
with the system.
The red LED will emit either a constant glow or a series of flashes, with a
2 second interval between each series. A series of flashes indicates there may
be a particular fault condition with the system. A constant glow or 3 flashes
(with the green LED off), or 1 flash (with a solid green LED) does not
necessarily mean there is a fault with the system.
