IMPORTANT SAFETY INFORMATION
WARNING – THIS APPLIANCE
MAY DELIVER WATER AT HIGH
TEMPERATURE. REFER TO THE
PLUMBING CODE OF AUSTRALIA
(PCA), LOCAL REQUIREMENTS AND
INSTALLATION INSTRUCTIONS TO
DETERMINE IF ADDITIONAL DELIVERY
TEMPERATURE CONTROL IS REQUIRED.
WARNING – FOR CONTINUED
SAFETY OF THIS APPLIANCE IT MUST
BE INSTALLED, OPERATED AND
MAINTAINED IN ACCORDANCE WITH
THE MANUFACTURER’S INSTRUCTIONS.
This water heater is not intended for
use by persons (including children) with
reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge, unless they have been given
supervision or instruction concerning
use of the water heater by a person
responsible for their safety.
Children should be supervised to ensure
they do not interfere with the water
heater. Ensure animals are supervised
so they do not interfere with the water
heater.
DO NOT store chemicals or flammable
materials, or spray aerosols near this
water heater.
DO NOT modify this water heater.
DO NOT operate the water heater with
any panels or covers removed.
If the water heater is not used for two
weeks or more, a quantity of hydrogen
(which is highly flammable) may
accumulate inside the water heater tank.
To dissipate this gas safely it is
recommended that a hot tap be turned
on for several minutes at a sink, basin or
bath, but not a dishwasher, clothes washer
or other appliance.
During this procedure there must be no
smoking, open flame or any other electrical
appliance operating nearby. If hydrogen is
discharged through the tap it will probably
make a sound similar to air escaping.
RELIEF VALVE:
The Pressure & Temperature Relief (PTR)
Valve must be installed directly into the
RP½” (DN15) socket marked “RELIEF
VALVE”.
The PTR valve rating is 1,000 kPa and
10 kW on electric water heaters.
The valve must not be tampered with or
removed. The water heater must not be
operated unless this valve is fitted and in
working order.
The drain line from the PTR Valve must
be installed in a continuously downward
direction in a frost free environment.
The PTR Valve is to be operated regularly
to remove lime deposits and to verify
it is not blocked. The drain line fitted to
the PTR Valve must be left open to the
atmosphere.
DANGER – FAILURE TO OPERATE THE
PTR VALVE EASING LEVER AT LEAST
ONCE EVERY SIX MONTHS MAY RESULT
IN THE WATER HEATER EXPLODING.
CONTINUOUS LEAKAGE OF WATER
FROM THE VALVE MAY INDICATE A
PROBLEM WITH THE WATER HEATER.
