Mains water supply
As mains pressure commonly exceeds 500 – 550 kPa, a pressure limiting
valve should be installed set to 500 kPa maximum. Note: In some States a
cold water expansion valve must be installed by regulation. This valve must
be set at 700 kPa maximum.
As shown in figure 1 and 2, an approved isolating valve, line strainer and
union are recommended between the cold water supply main and the cold
water inlet of the Everlast™ Series 2000 water heater. Plumbing compliance
(safety) regulations require the installation of the supplied Non Return Valve
to ensure that the appliance does not empty during normal use or interrupted
water supply.
The Everlast™ Series 2000 water heater is designed to ensure total drainage
for flushing if required. It is recommended that a drain cock be installed on
the cold water inlet pipe adjacent to the heater to facilitate flushing annually in
poor water quality areas.
Hot water connection should be as shown in figure 1 and 2. It is recommended
that hot water outlet pipes are fully insulated withweatherproof insulation, and
that the hot water outlet pipe is slightly curved or stepped down adjacent to the
water heater outlet to provide a positive heat trap and avoid thermal siphoning
from the heater.
