Check the items below before making a service call. You will be charged for attending to any condition or fault
that is not related to manufacture or failure of a part.
NOT ENOUGH HOT WATER (OR NO HOT WATER)
This can occur with new installations and is normally related to some misunderstandings as to the use of the
booster heating unit.
•
Insufficient sunlight
Insufficient sunlight due to cloudy weather during hotter months or
low solar energy contribution in colder months may mean the
booster heating unit is required to boost more often.
Ensure the booster heating unit is being used as advised. Refer to
"Booster Control"
on page 14.
•
Booster heating unit not operating
Inspect the isolating switch marked "HOT WATER" or "WATER
HEATER" at the switchboard and the isolating switch (if one is
installed) near the solar storage tank and ensure they are turned
on.
Check the timer (if one is installed) and it's settings to ensure power
is available to the booster heating unit.
Note: Check the electricity supply to which the unit is connected. If on an Off-Peak or time controlled
supply, remember heating hours are restricted.
Check the fuse or circuit breaker marked "HOT WATER" or "WATER HEATER" at the switchboard.
•
Solar Control Unit
Check the power outlet for the solar control unit is switched on.
•
Green LED is off or red LED is flashing on Solar Monitor
If the green LED is off or the red LED is flashing on the Solar Monitor label, there may be a problem with
the solar water heater operation and solar gain is not being achieved. This will result in the booster heating
unit operating to provide all of the hot water required.
Switch off the electrical supply at the power outlet to the solar control unit for a few seconds, then switch
on again.
If the green LED remains off or the red LED recommences to flash, then count the number of flashes and
phone your nearest Solahart Dealer to arrange for an inspection.
•
Collectors shaded
If trees or other objects shade the solar collectors or if the glass is dirty, the effectiveness of the solar
collectors will be greatly reduced. Have the trees trimmed or the solar collectors relocated if the obstruction
is permanent or clean the collector glass (refer to
•
Collector area is too small
For most installations, the number of solar collectors recommended in Solahart literature has been proven
to provide the required solar energy to meet the average family needs. However, in some circumstances,
it may be necessary to install an additional solar collector.
•
Air in collectors (no solar gain)
It is possible under certain conditions, such as when the pipe work has been opened, that air may become
trapped in the solar collectors. This will prevent the circulator from moving water around the collector
circuit. Have the collector circuit purged of air. Phone your nearest Solahart Dealer.
•
Relief valve running
Is the relief valve discharging too much water?
