IN-SERIES BOOSTER WATER HEATER OPERATING TOO FREQUENTLY
You may find that the in-series booster water heater operates more frequently than expected. This will
occur when the solar preheat water temperature is lower than the temperature setting of the in-series
booster water heater. This may be experienced during periods of low solar energy gain or if there has
been heavy hot water usage.
COLLECTOR GLASS
Warranty
DOES NOT
cover breakage of solar collector glass. Check your household insurance policy
covers collector glass breakage.
Warning:
Collector glass must not be replaced whilst the solar collector is on the roof.
The collector glass is not offered as a replacement part and no attempt should be made to remove it.
Should the solar collector require replacement, contact your nearest Solahart Dealer.
TEMPERATURE PRESSURE RELIEF VALVE RUNNING
•
Normal Operation
It is normal and desirable this valve allows a small quantity
of water to escape during the heating cycle. However, if it
discharges more than a bucket full of water in 24 hours,
there may be another problem.
•
Continuous dribble
Try gently raising the easing lever on the relief valve for a
few seconds (refer to
“Temperature Pressure Relief Valve”
on page 10). 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 until the water heater is cold - then stops until water reheats
The water heater
must
be switched off at the isolating switch or switchboard. Phone your nearest
Solahart Dealer to arrange for an inspection.
EXPANSION CONTROL VALVE RUNNING
If an expansion control valve is fitted in the cold water line to the water heater
(refer to page
26
)
it may
discharge a small quantity of water instead of the temperature pressure relief valve on the water heater.
The benefit is that energy is conserved as the discharged water is cooler.
