CONNECTIONS – PLUMBING
A disconnection union must always be provided at the cold water inlet, solar
cold water outlet, solar hot 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.
