HOW LONG WILL THE BOILING WATER UNIT LAST?
There are a number of factors that will affect the length of service the boiling water
unit will provide. These include but are not limited to the water quality, the water
"Precautions"
usage pattern etc. Refer to below However, your boiling water unit is
supported by a comprehensive Rheem warranty (refer "Rheem Warranty" on page
33).
PRECAUTIONS
The boiling water unit must be maintained in accordance with the Owner‟s Guide and
Installation Instructions.
If this boiling water unit is to be used where an uninterrupted boiling water supply is
necessary for your application or business you should ensure that you have back up
redundancy within the building. This should ensure the continuity of boiling water
supply in the event that this boiling water unit were to become inoperable for any
reason. We recommend you seek advice from your plumber or specifier about your
needs and building back up redundancy.
HOW YOUR BOILING WATER UNIT WORKS
The boiling water unit is designed to operate using mains cold water pressure by
connecting directly to the mains water supply. If the mains supply pressure in your
area exceeds 1000kPa a secondary pressure limiting valve must be fitted.
The supply pressure should be greater than 50 kPa (3-10Litre), 75kPa (15-25L) or
100kPa (40L) for the Rheem Boiling Water Unit operating to its optimum
performance.
BOILING WATER
The Rheem Boiling Water Unit is electronically controlled to obtain the maximum
performance, and incorporates further safety devices to prevent over temperature
and over filling.
ELECTRONIC CONTROLLER & TIMER (701 and 702 Series)
Your Rheem boiling water unit incorporates smart heating software and an electronic
timer to obtain the best efficiency for the energy used. The electronic timer allows the
user to program when the unit is on or off and when the sleep mode activates to
save energy. Also the operator has the availability to indicate and diagnose any
system faults that occur without the need to unnecessarily call for a service
technician. (Refer "Setting the Timer" on page 7)
ECO TIMER (703 Series)
The 703 Series also incorporates smart heating software and an electronic „Eco‟
timer to obtain the best efficiency for the energy used. The Eco timer allows the unit
to activate „sleep mode‟ to save energy after 2 hours of inactivity.
