Hot Water Connection:
The hot water pipe can be connected
to either of the RP¾”(DN20) sockets
marked “OUTLET” at the top of the
water heater. Before connecting
the pipework, it is essential that a
dielectric fitting
is installed in the
socket. Refer to Dielectric Fittings on
page 5.
If hot water pipes are to be connected
to both outlet sockets, dielectric fittings
must be installed in both sockets.
Additional dielectric fittings are available
from your local Dux supplier.
The unused socket marked “OUTLET”
is to be plugged with one of the brass
plugs supplied inside the electrical cover
of the water heater. Instructions on how
to remove the electrical cover can be
found on page 11. Ensure that a sealing
material is applied to the brass plug to
prevent water leaks.
It is recommended that all hot water
pipes are insulated. Hot water pipes
installed outdoors should be insulated
with UV stabilised insulation.
Plastic pipes or fittings shall not be used
within 1 metre of the outlet although
they may be used downstream of a
temperature control valve. Refer to
AS/NZS 3500.4 for further details.
Temperature Protection:
Water heaters can produce very hot
water. To reduce the risk of scald injury,
it is mandatory under the requirements
of AS/NZS 3500.4 that an approved
temperature control device is fitted to
the hot water supply to outlets used
primarily for personal hygiene. This
device should be checked at regular
intervals to ensure its operation and
settings remain correct.
We recommend using a HeatGuard
Ultra Tempering Valve made by RMC.
