Pressure & Temperature Relief Valve
The Pressure & Temperature Relief
Valve is supplied loose with the water
heater. The valve rating is:
All models = 1000kPa
The PTR valve must be installed directly
into the top socket marked “RELIEF
VALVE”. The drain line from this valve
must run in a continuously downward
direction in a frost-free ambient
position with the discharge end left
open to atmosphere permanently.
The PTR Valve is not intended to enable
connection of the water heater to
supplementary energy sources such as
solar panels or slow combustion stoves
(refer AS/NZS 3500.4 for guidance on
these types of installations).
After the cold water has been
connected, open the PTR Valve for
approximately 10 seconds by lifting
the lever on the valve to ensure water
is relieved to waste through the relief
drain pipe. Lower lever gently and
check that it closes correctly.
The PTR 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 PTR Valve should be checked for
adequate performance or replaced at
intervals not exceeding 5 years, or less
in areas where local regulations apply.
Important: The PTR Valve and its drain
outlet pipe must not be sealed or
blocked. It is normal for the PTR valve
to leak a small amount of water during
heating cycles.
Danger
Failure to operate the relief valve
easing lever at least once every six (6)
months may result in a problem with
the water heater and in some cases the
tank may explode.
Warning: A separate drain line must
be run for this relief valve. It is not
permitted to couple drain lines from
relief valves into a single common
drain line.
Cold Water Connection
An approved isolating valve, non
return valve, line strainer (optional but
recommended), and union must be
fitted between the supply main and the
RP¾/20 socket marked INLET at the
bottom of the water heater. All fittings
must be approved by the relevant
Authority. See the diagram on page 4
for details.
Note for S.A. and W.A.: It is a state
requirement that an expansion control
valve be fitted on the cold water
supply line between the non return
valve and the water heater. See the
diagram on page 4 for details.

Temperature Protection
Water heaters can produce very hot
water. To reduce the risk of scald
injury, it is mandatory under the
requirements of Australian Standard
AS/NZS3500.4 that a suitably
approved temperature control device
be fitted to the hot water supply to
outlets used primarily for personal
hygiene. This valve should be checked
at regular intervals to ensure its
operation and settings remain correct.

80L to 400L Electric Storage Water Heaters
Electrical Connection
This water heater is designed for
single phase 240V A.C supply only.
The electrical connection must
comply with Local Supply Authority
Regulations and AS/NZS3000.
Connections are made at the terminal
block inside the water heater, and
a means for disconnection must be
incorporated in accordance with the
wiring rules.
Entry to the connection area is
through the hole beneath the electrical
cover, designed to accept a 20mm
conduit. The electrical cover may be
removed by undoing the two screws
on the cover and sliding the cover
downwards to disengage the top
edge. Ensure that the conduit entry
is well sealed to achieve correct
weatherproofing.
Note: This water heater is fitted
with a thermostat and over-
temperature energy cut-out. Under
no circumstances should the water
heater be operated without both
these devices being in the circuit.
Replacement must be carried out
only by a licensed tradesperson or the
manufacturer.
Danger: The operation of the thermal
cut-out indicates a possibly dangerous
situation. Do NOT reset the thermal
cutout until the water heater has been
serviced by a licensed tradesperson.
Caution: Water heater must be filled
with water before turning on the
electricity supply.
Electrician: Press the reset button
on thermostat to ensure over-
temperature cut-out is set.
When supply wiring has been
connected, supply wires must be kept
lower than the terminal block.

Safety
This appliance 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 appliance by a
person responsible for their safety.
Children and animals should be
supervised to ensure that they do not
interfere with the appliance.
Filling The Water Heater
Open all hot water taps. Open isolating
valve at the cold water inlet slowly and
allow water heater to fill until water
flows through the system. Close each
hot water tap after the air is expelled
from its line. As noted previously
power is not to be turned on until the
water heater is filled with water.
Water Quality
Your Thermann water heater has been
manufactured to suit water conditions
of most Australian metropolitan
supplies. Please note that harsh water
supplies can have a detrimental
eect on the water heater and its life
expectancy. If you are unsure about
your water quality you can obtain
information from your local water
supply authority.
The water heater is designed for use in
areas where the Total Dissolved Solids
(TDS) content of the water supply
is less than 2500 mg/L. In areas
where the TDS exceeds 600mg/L it
is possible that the magnesium alloy
anode (supplied in the heater) may
become over-reactive. To alleviate this,
a hard-water model is recommended
or the magnesium alloy anode should
be replaced with an aluminium
alloy anode.
Water can also be very corrosive, the
measure of this is the saturation index.
If the water saturation index is greater
than 0.40, an expansion control
valve should be fitted. If the index
is greater than 0.80, the electrical
heating element in the water heater
should be replaced with a low power
density Incoloy heating element.
Please consult our Customer Service
Department for advice if required.
Caution
If the water heater is left in an
operating condition and unused for
two weeks or more, a quantity of
hydrogen (which is highly flammable)
may accumulate in the top of the
water cylinder. 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 an unusual sound as
with air escaping.
Where the water heater is not installed
in accordance with the listed advice, the
water heater will not be covered by the
Terms of Warranty.
