INSTALLATION
REDUCING HEAT LOSSES
The cold water line to and the hot water line from the water heater must be insulated in accordance with the
requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed.
The pipe work between the solar storage tank and the solar collectors may be required to be insulated. Refer
"Warning: Plumber Be Aware"
to
SADDLING - PIPE WORK
To prevent damage to the cylinder when attaching pipe clips or saddles to the solar storage tank jacket, we
recommend the use of self-drilling screws with a maximum length of 13 mm. Should pre-drilling be required,
extreme caution must be observed when penetrating the jacket of the solar storage tank.
Note: If the cylinder is damaged as a result of attaching pipe clips or saddles to the jacket, any resultant
faults will not be covered by the Rheem warranty.
BOOSTER HEATING UNIT
The booster heating unit is for heating the water at times of low solar energy gain, such as during very cloudy
or rainy weather, or during the colder months. Refer to
connection requirements and control options of the booster heating unit.
If this water heater is installed with an in-series booster, then the electric booster heating unit in the solar
storage tank will not need to be connected to a power supply.
PLASTIC END COVER
A set of plastic end covers is available for installation to the ends of the tank. These ends provide an
aesthetically pleasing finish to the system by housing the pipe work and electrical connection within them.
Where a plastic end cover is to be installed, the plumbing and electrical connections need to be routed to suit.
Check the installation documentation that comes with the plastic ends for these details.
TANK REPLACEMENT
If replacing a tank, the replacement tank must be fitted with a new temperature pressure relief valve and
expansion control valve. These valves are not supplied with the tank.
OVER-TEMPERATURE PROTECTION
AS/NZS 2712:2007 includes a requirement for a no-load system operation test. In order to comply with this
requirement, 52L series systems installed with CSA2007 collector(s) must be fitted with TRV, and 52H series
systems installed with two or more CSA2007 collectors must be fitted with OTP.
The systems listed below must be installed using the Over-Temperature Protection Parts Kits described to
comply with AS/NZS 2712:2007.
52L Series System Over-Temperature Protection
The following systems require the installation of a Thermosiphon Restrictor Valve (TRV) kit to meet the
