WATER INLET AND OUTLET
Each model water heater has dual handed cold and hot water connections. The
water connections can be made to either side.
All pipe work must be cleared of foreign matter before connection and purged
before attempting to operate the water heater. All olive compression fittings must
use brass or copper olives. Use an approved thread sealant such as Teflon tape
on all sealing threads.
An isolation valve and non-return
valve must be installed on the cold
water line to the water heater. An
acceptable arrangement is shown in
the diagram. Refer also to
on page 29 and to
on page 28.
A disconnection union must always
be provided at the cold water inlet
and hot water outlet on the water
heater to allow for disconnection of
the water heater.
This water heater has either a plastic dip tube or fitting
liner in the inlet and outlet fittings (see diagram). These
must be in place for the water heater to function
properly. Do not remove or damage them by using
heat nearby. They will be pushed into the correct
position as the fitting is screwed in.
This water heater is intended to be permanently connected to the water mains
and not connected by a hose-set. A braided flexible hose or semi-flexible
connector may be used for connection to the water heater, where permitted by
AS/NZS 3500.4.
