ERROR CODE
The in-series gas booster provides a diagnostic error code in the event of an interruption to its operation. The
error code is displayed on the front of the in-series gas booster on the OK MONITOR as a numerical value
on the 244 627 models or a series of flashes on the 244 620 models. If an error code appears:
Close the hot tap and switch off the electrical supply to the in-
series gas booster.
Wait 5 minutes, then switch on the electrical supply to the in-series
gas booster and open a hot tap.
If the error code persists, take note of the numerical value (627 model)
or the number of flashes (620 model) and turn off the hot tap. Phone
Rheem Service or their nearest Accredited Service Agent to arrange
for inspection.
HIGHER THAN EXPECTED ENERGY BILLS
With the installation of your new solar hot water system, maximum energy savings can be achieved with
careful planning of hot water usage. Should you at any time feel your energy bill is higher than expected, we
suggest you check the following points:
Is the relief valve running excessively?
Refer to “Temperature Pressure Relief Valve Running” on page 19.
Is one outlet (especially the shower) using more hot water than
you think?
Refer to In-Series Booster Operating Too Frequently on page 18.
Is there a leaking hot water pipe, dripping hot water tap, etc?
Even a small leak will waste a surprising quantity of hot water and
energy. Replace faulty tap washers, and have your plumber rectify
any leaking pipe work.
Is the in-series gas booster operating too frequently?
Refer to In-Series Booster Operating Too Frequently” on page 18.
Has there been an increase in hot water usage?
An increase in hot water usage may result in an increase in booster operation.
Has your water heating tariff rate been increased by your energy retailer since your previous bill?
IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU NEED ASSISTANCE,
PHONE RHEEM SERVICE OR THEIR NEAREST ACCREDITED SERVICE AGENT.
