WATER INLET AND OUTLET
The 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 threaded joints.
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
Water Delivery"
on page 33 and to
page 32.
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.
CONDENSATE DRAIN
A condensate drain hose is supplied with the water heater.
•
Securely connect the condensate drain hose to the condensate drain spigot at the rear of the heat pump,
•
Position the drain hose so it has a continuous fall all the way to the discharge outlet and there are no
bends or distortions in it after it is installed,
•
It may be necessary to use hose clips to secure the drain hose in position,
•
Locate the discharge outlet of the drain hose such that flow out of the pipe can be easily seen and not
cause damage or nuisance.
