Pressure & Temperature Relief

Valve

The Pressure & Temperature Relief Valve

is supplied loose with the water heater.

Please refer to the specications

table on page 6 for the valve ratings.

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).

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

tted 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.

Note: Brass plugs are supplied with

the water heater to plug off the unused

ttings. Ensure that a sealing material is

applied to the plugs to prevent leaking.

Cold Water Connection

An approved isolating valve, non

return valve, line strainer (optional but

recommended), and union must be

tted between the supply main and

either of the RP¾/20 sockets marked

“Inlet” at the bottom of the water heater.

All ttings 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 a pressure relief valve

be tted on the cold water supply line

between the non return valve and the

water heater. See the diagram on page

4 for details.

Plumbing Connections

Hot Water Connection

The hot water pipe should be connected

to either of the RP¾/20 sockets marked

OUTLET at the top of the unit. For the

most economical operation of the water

heater, it is recommended that all hot

water lines are insulated. Please check

local regulations regarding the use of

hot water supply pipework that are not

made of copper.

Building Flow and Return

Never install a building circulated ow

and return line with a Rinnai Electric

water heater on a timed or controlled

tariff.

If a ow and return line is required, we

recommend that you install a backup

storage water heater on a continuous

tariff. The ow and return line should

also include time control the building

circulation loop to help reduce energy

usage.

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 tted 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.

Note: a combined isolating valve/non-return valve/line strainer may be used.

Expansion valve only required where local regulations demand.

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.

For models pre-wired with a exible

lead, if the supply cord is damaged, it

must be replaced by the manufacturer,

its service agent, or similarly qualied

person in order to avoid hazard.

For models not pre-wired with a exible

lead, 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 element cover,

designed to accept a 20mm conduit.

The element 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 weatherproong.

Note: This water heater is tted 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 qualied electrician 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 qualied person.

Caution: Water heater must be lled

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 ll until water ows

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

lled with water.

Water Quality

Your Rinnai water heater has been

manufactured to suit water conditions of

most Australian metropolitan supplies.

Please note that harsh water supplies

can have a detrimental effect 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,

the magnesium alloy anode should be

replaced with an aluminium alloy anode,

available from your local Rinnai supplier.

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 tted. If the index is greater

than 0.80, the water heater installed

should be a Hard Water Model. Please

consult our 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 ammable) 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 ame 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.
