Save A Service Call - Rheem 511161 Owner's Manual And Installation Instructions

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)
 Insufficient sunlight
Insufficient sunlight due to cloudy weather during hotter months or low solar energy contribution in colder
months may mean the in-series water heater operates more often.
 Solar Control Unit
Check the power supply cord is plugged in and the power outlet switched on.
Is power available in the house? Try using another electrical appliance.
 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 in-series gas
booster 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 Rheem Service or their nearest
Accredited Service Agent to arrange for an inspection.
 Collector(s) shaded
If trees or other objects shade the solar collector(s) or if the glass is dirty, the effectiveness of the solar
collector(s) will be greatly reduced.
Have the trees trimmed or the solar collector(s) relocated if the obstruction is permanent or clean the
collector glass.

 Collector area is too small
For most installations, the number of solar collector(s) recommended in Rheem literature has been proven
to provide the required solar energy to meet the average family needs. However, in some circumstances,
it may be possible to install a second LCS or NPT200 solar collector.
 Air in collector(s) (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 collector(s). This will prevent the circulator from moving water around the collector
circuit. Have a plumber purge the collector circuit of air.
 Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think?
Very often it is not realised the amount of hot water used, particularly when showering. Carefully review
the family's hot water usage. As you have installed an energy saving appliance, energy saving should
also be practised in the home. Adjust your water usage pattern to take advantage of maximum solar gains.
Have a plumber install a flow control valve to each shower outlet to reduce water usage.
 Temperature pressure relief valve running
Is the relief valve discharging too much water?
