MAINS WATER SUPPLY
Where the mains water supply pressure exceeds that shown in the table below,
an approved pressure limiting valve is required and should be fitted as shown in
the cold water connection diagram on page 35.
Model 340
Temp pressure relief valve setting 1400 kPa
Expansion control valve setting * 1200 kPa
Max. mains supply pressure
With expansion control valve 960 kPa
Without expansion control valve 1120 kPa
* Expansion control valve not supplied with the water heater.
TANK WATER SUPPLY
If the water heater is supplied with water from a tank supply and a pressure pump
system is not installed, then the bottom of the supply tank must be at least 1 m
above the highest point of the hot water plumbing system, including the water
heater. Care must be taken to avoid air locks. The cold water line to the water
heater should be adequately sized and fitted with a full flow gate valve or ball
valve.
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.
SADDLING - PIPE WORK
To prevent damage to the cylinder when attaching pipe clips or saddles to the
water heater 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 water heater.
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.
