LED OPERATION
on page 12 for further information on the types of flashes the LEDs produce.
•
Both LEDs are Off (no illumination)
If both LEDs remain off, check there is a power supply
to the water heater.
“Is the electricity switched on?”
on page 21.
If there is power available, there may be a problem
with the water heater. Phone your nearest Solahart
Dealer to arrange for an inspection.
•
Red LED is Solid (constant illumination)
If the red LED remains on with a solid illumination,
there is a problem with the water heater.
Phone your nearest Solahart Dealer to arrange for an
inspection.
•
Red LED is illuminating with a Slow Blink Flash (once every ten (10) seconds)
If the red LED is illuminated with a slow blink flash, the water heater may not be detecting the Energy
Management Unit or PLT network.
If an Energy Management Unit is installed, there may be a problem with the EMU or the water heater.
Phone your nearest Solahart Dealer to arrange for an inspection.
TEMPERATURE PRESSURE RELIEF VALVE OR EXPANSION CONTROL VALVE RUNNING
•
Normal Operation
It is normal and desirable the temperature pressure relief valve or
expansion control valve (if fitted) allows a quantity of water to escape
during the heating cycle. This quantity should be equal to approximately
1/50 of the hot water used, as water expands by this volume when
heated. However, if it discharges more than a bucket full of water in
24 hours, there may be another problem.
The expansion control valve (if fitted) will discharge water instead of the
temperature pressure relief valve as it has a lower pressure rating. A
benefit is that energy is conserved as the discharged water is cooler. This
valve is installed in the cold water line to the water heater (refer to the
on page 31).
•
Continuous dribble
Try gently raising the easing lever on the relief valve for a few seconds
(refer to
on page 8). This may dislodge a small particle of
foreign matter and clear the fault. Release the lever gently.
•
Steady flows for long period (often at night)
This may indicate the mains water pressure sometimes rises above the
designed pressure of the water heater. Ask your installing plumber to fit
a pressure limiting valve.
Warning:
Never replace the relief valve with one of a higher pressure rating.
•
Heavy flows of hot water from the temperature pressure relief valve until water heater is cold -
then stops until water reheats
The water heater
must
be switched off at the switchboard. Phone your nearest Solahart Dealer to arrange
for an inspection.
