About your cylinder
Water is heated by an electric element, or elements located in the cylinder. The
temperature of the water is controlled by an automatic thermostat that is set by
your installer, usually to 65 °C to disinfect the water for legionella1.
1Legionella is a bacterium that can cause Legionnaires’ disease―a severe form of pneumonia
Safety messages
• Element cover
Do not remove the element
cover as this will expose
230 V wiring and must
only be removed by an
authorised person.
• Damagedcomponents
If any component is
damaged, it must be
replaced by an authorised
person using Rinnai
replacement parts.
• Child supervision
Children should be
supervised to ensure they
do not play with any part of
the hot water system.
• Hot pipe work
Care should be taken not to
touch the pipe work from
the cylinder as this could be
very hot.
Safety devices
Your cylinder is fitted with a:
• Temperature & Pressure
and Relief (TPR) valve that
ensures the water remains
at a safe pressure and
temperature.
• Automatic thermostat
to maintain water
temperature.
• Temperature override
cutout for heating element.
In the case of a standard
cylinder (not installed in
a solar application), the
operation of the thermal
cutout can indicate a
dangerous situation. Do not
reset the thermal cutout
until the water heater has
been serviced by a qualified
person.
Do not operate the system
unless all the safety devices are
fitted and are in working order.
It is also important that you do
not tamper or remove any of
these devices.
Cylinder thermostat setting
Your cylinder thermostat has
been set with a temperature
setting to disinfect the water for
legionella.
Thermostat settings
must only be adjusted
by an electrician or
other suitably qualified
tradesperson.
Hydrogen gas
If hot water is not used for two
weeks or more, a quantity of
hydrogen gas, which is highly
flammable, may accumulate in
the cylinder.
To dissipate safely, it is
recommended a hot tap
(non-electrical) be turned on
for two minutes at a sink, basin
or bath. During this procedure
there must be no smoking, open
flame, or any other appliance
operating nearby.
Turning the cylinder on/off
If you plan to be away for only a
few nights we suggest you leave
the system switched on. If it is
necessary to switch it off, when
switching back on, remember
that the cylinder will take time
to heat back up again.
Draining and filling the system
This normally occurs during
installation or servicing and
must be carried out by an
authorised person.
LIMITED
WARRANTY*
Important
All cylinders have the potential to leak water. To minimise damage to
other areas of your home, ensure that your cylinder has been installed
with a drip tray—the person doing the installation is responsible for
doing this.
* Refer to the warranty terms and conditions in this guide for more information.
IMPORTANT

Maintenance and servicing
Hot water systems, like cars, require regular maintenance and servicing. To ensure
longevity of your cylinder we recommend the following.
Period What needs to be done
Every six months TPR (temperature & pressure relief) valve—operate the easing gear
Year five Inspection and service of the entire hot water system, including the element*
Every 24 months
after year five
Inspection and service of the entire hot water system, including the element*
* In hard water areas the element(s) must be periodically descaled. To do this the unit must be drained and the element(s)
removed.
TPR valve
This valve is located near the
top of the cylinder and is
essential for safe operation.
The TPR valve works by
automatically venting hot water
if the temperature or pressure
of the water in the cylinder gets
too high.
Every six months operate the
easing gear to remove lime
deposits and to check that
it is not blocked. As this will
discharge hot water, ensure no
one is near the drain line.
Failure to operate the
relief valve easing gear
at least once every six
months may result in the
water heater exploding.
Continuous leakage of
water from the valve may
indicate a problem.
It is important that you raise
and lower the easing gear
gently. During the operation,
if the valve does not discharge
water when the easing gear is
lifted, or does not seal again
when closed, arrange for an
authorised person to come and
inspect the system immediately.
During servicing of your
cylinder the TPR valve
needs to be checked
and/or replaced. This
needs to be done by an
authorised person at
intervals not exceeding
five years, or more
frequently in areas where
the water is classified as
hard.
A TPR valve must not be
replaced with one that has a
higher pressure rating than that
specified for the cylinder.
Maintenance and servicing
Rinnai has a maintenance,
service, and spare parts network
with personnel who are fully
trained and equipped to give
the best advice on your Rinnai
product. Regular maintenance
and servicing is not covered by
the Rinnai warranty.
For help locating a service
person in your area call 0800

Troubleshooting
Do not attempt to carry out any work other than that mentioned in this
troubleshooting section. If you have any other faults or problems, please contact
your installer, or contact Rinnai.
Problem Possible solution
Lack of hot
water or no hot
water
Isthereelectricitysupplytothecylinder?
Check that the isolating switch marked ‘hot water’ or ‘water heater’, at
the meter box, is switched on. Also check any isolating switches near
the water heater are switched on.
Check the fuse or circuit breaker marked ‘hot water’ or ‘water heater’
at the meter box. Repeated failure of the fuse or tripping of the circuit
breaker indicates a fault, which must be investigated by an authorised
tradesperson.
Most hot water cylinders are controlled at peak times by your electricity
supplier via a ripple relay. Contact your electricity supplier to determine
if there have been any issues with the power supply.
Lack of hot
water or no hot
water
Areyouusingmorehotwaterthanyouthink?
Often you don’t realise how much water is actually being used. This
applies especially when showering. Typical flow rates for showers is
approximately 8-10 litres per minute. Conduct a simple experiment
by placing a measured bucket under your shower for ten seconds and
multiply by six to determine the amount of water produced over a
minute. If your result is significantly more than the rates mentioned you
may want to consider installing a low flow shower rose―available at all
good plumbing stores.
Lack of hot
water or no hot
water
Coldwaterreliefvalvedischargingcontinuously?
It is normal for the cold water relief valve to discharge a small quantity of
water through the drain line. If water is discharging continuously there
may be a fault with one of the valves, contact the installer to discuss.
Water too hot If possible check the temperature of the water coming out of a hot
water tap with a thermometer. If it is higher than 55 °C then this
indicates a problem with your system—contact an electrician for
advice.
High electricity
bills
If you think your electricity bill is too high, investigate the following:
• Has your electricity tariff changed?
• Is your cold water relief valve discharging continuously?
• Are you using more hot water than normal?
• Has there been any leaking hot water pipes, or taps?

Installation
Installation, servicing and repair
shall be carried out only by
authorised personnel.

Plumbing setup
Plumbing setup for a mains pressure stainless steel cylinder
Base requirements
Tanks should be installed on a flat level base of sufficient strength to support the weight of the
water heater when full.
The water heater must also be suitably restrained against seismic activity, ‘G12/AS1 Figure 14’
details an acceptable method of restraint.
Drip tray/catch pan - MUST be fitted
The Rinnai warranty does not cover any consequential loss from leaks to the cylinder, so it’s
important a suitably drained drip tray/catch pan is fitted.
Drip tray
The appliance is not intended to be connected by a hose-set

Mains pressure indoor stainless steel cylinders: Owner and installer guide: 20132-D 04-15 | 11
Storage and delivery temperatures
Storage temperature
Local regulations state that hot water shall be stored at a minimum temperature of 60 °C.
Thermostat settings must only be adjusted by an electrician or other suitably qualified
tradesperson. The access cover to the element and thermostat must only be removed
by an electrician or other suitably qualified tradesperson.
Sanitary fixtures delivery temperature
Water temperatures over 55 °C can cause severe scalds. Local regulations must be considered
regarding temperature limitations of hot water supplied to areas used primarily for personal
hygiene. The temperature is limited to 45 °C for early childhood centres, schools, nursing
homes or similar facilities and 55 °C for all other buildings. To comply with these requirements, a
temperature limiting device, such as a tempering or thermostatic mixing valve will be required
on all installations.
WARNING
Pipe work
It is the installer’s responsibility to adequately size the distribution pipe work in a property to
ensure sufficient performance from all outlet fittings. Water pipe sizing should be performed
in accordance with AS/NZS 3500.4 and/or G12 AS1. Pipe sizing and valve selection must be
performed to allow for the water supply pressure.
A drain off tap or line must be fitted to the inlet of the water heater.
All hot water pipe work should be insulated with polythene foam or equivalent insulation to
optimise performance and energy efficiency.
To prevent damage to the water heater when attaching pipe clips or saddles to the jacket, it is
recommended that self drilling screws with a maximum length of 12 mm are used. If drilling is
required take extreme care not to penetrate the inner cylinder.

Water quality
HJ Cooper by Rinnai water heaters are manufactured to suit most
NZ council water supplies. However some water supplies can have
a detrimental effect on the water heater, its operation, and life
expectancy.
Pitting corrosion
The HJ Cooper by Rinnai stainless steel tanks are made from 2101 grade duplex stainless steel.
This material has very good resistance to pitting corrosion with a Pitting Resistance Equivalent
Number (PREN) of 26. This is a commonly used engineering indicator of corrosion resistance in
stainless steel materials. The higher the PREN number the greater the resistance. In comparison
304 grade stainless, which is commonly used in domestic cookware and kitchen sinks, has a
PREN number of 19. This means that HJ Cooper by Rinnai stainless steel tanks are highly resistant
to pitting corrosion, but not completely immune from it.
Pitting corrosion may occur in the form of deposit attack if the water supply has a high
percentage of dissolved solids present. It is advised in areas with a high concentration of
dissolved solids in the water supply that consultation with water quality and filtration experts be
undertaken.
Hard water
Hard water (containing calcium carbonate) can cause scaling on hot surfaces. We recommend
a water temperature of no more than 65 °C to minimise scale build-up. Scale reducing or water
softening devices should be considered in hard water areas. The unit is not guaranteed against
damage due to scaling.
Water quality outside the limits (as set down below) will void this warranty. Water quality tests must be
carried out at the customer’s own cost but Rinnai will reimburse any reasonable test costs where water
quality is within the limits tabled.
WaterQualityandImpurityLimits
TDS (Total Dissolved Solids) Total Hardness CaCO3Dissolved (free) CO3pH Langelier Index
Up to 600 mg/L or ppm Up to 200 mg/L or ppm Up to 25 mg/L or ppm 6.5-8.5 Between -1.0-0.8
Most metropolitan water supplies fall within these limits. If you are unsure about water quality, please
contact Rinnai and we will provide you with the details of an authorised agency able to test your water
for compliance to Rinnai standards. If sludge or foreign matter is present in the water supply, a suitable
filter should be incorporated in the water supply.
Some examples of water quality issues where water may need to be treated:
• Hard water (areas including Wanganui)
• Aggressive water (areas including Christchurch)
• Both hard and aggressive water (some bore water)

Mains pressure indoor stainless steel cylinders: Owner and installer guide: 20132-D 04-15 | 13
Electrical supply and connections
The electrical connection must be carried out by a qualified person in accordance
with NZ Electrical Regulations. The water heater must have the heating element
connected to an independent, fused, AC 230 V 50 Hz power supply with an isolating
switch installed at the switch board.
• The water heater must be filled with water prior to connection to the power supply
• Disconnect all power prior to installation and commissioning
• Household wiring to the heater must be capable of withstanding the appliance load
• Fixed wiring must be protected from contact with the internal hot surface of the water
heater
Electrical access is via a hole in the element cover for mounting with an approved electrical
conduit gland. For entry to the element cover remove the two fixing screws.
Connect all PHASE and NEUTRAL wires in accordance with the wiring diagram. Inspect and
ensure all wiring links are secure prior to fixing the access cover and turning the power on.
To ensure the over-temperature and energy cutout is set press the ‘reset’ button on the
thermostat.
The appliance is intended to be connected to cables of fixed wiring which has a cross-sectional
area of 1.5 mm2 - 2.5 mm2.

Warranty examples in the real-world
We understand warranty information can be confusing. To help clarify what this means in the real-
world we have developed some single residential application scenarios to clarify what would fall within
warranty and what wouldn’t.
Scenario Ageofpart/
cylinder
Withinwarranty
Faulty thermostat 10 months Yes All costs covered by Rinnai.
Faulty element 3 years No All costs covered by the owner.
Cylinder leaks as a result of
a faulty inner cylinder and
causes damage to carpets
and flooring
11 months Yes Cost of cylinder replacement covered by
Rinnai. Consequential loss, damage to
carpets and flooring, is not1.
Inner cylinder fails 7 years Yes Cost of cylinder replacement covered by
Rinnai. The cost of removal of the cylinder,
re-installation, and labour costs are the
responsibility of the owner.
Outer cylinder showing signs
of corrosion
3 years No Only the inner cylinder is covered by
warranty
1Consequential losses
All cylinders are required to be installed with a drip tray, this is a mandatory requirement of the
installation. If damage is caused by a leaking cylinder that has not been installed with a drip tray the
owner can seek compensation through the installer or consider claiming on insurance.
Proratawarrantyexplanationandscenarios
Years 11-20 of the HJ Cooper by Rinnai Mains Pressure Stainless Steel cylinders are covered by a pro
rata warranty where the replacement cost is reduced according to the age of the cylinder. This is
calculated using the following formula.
Original purchase price x remaining warranty in years ÷ total warranty period of the cylinder.
Scenario example 1
A warranty claim is approved where an inner cylinder fault is identified. The cylinder is 11 years old.
Original purchase price was $1000. The cylinder needs replacing at a cost of $1200. The owner in this
example would need to pay $750 for the replacement cylinder plus labour and installation costs.
$1000 (orig. purchase price) x 9 (remaining warranty in years) ÷ 20 (total warranty period of cylinder) = $450
$1200 (replacement cost of cylinder) - $450 = $750 (owner to pay*)
Scenario example 2
A warranty claim is approved where an inner cylinder fault is identified. The cylinder is 18 years old.
Original purchase price was $1000. The tank needs replacing at a cost of $1200. The owner in this
example would need to pay $1100 for the replacement cylinder plus labour and installation costs.
$1000 (orig. purchase price) x 2 (remaining warranty in years) ÷ 20 (total warranty period of cylinder) = $100
$1200 (replacement cost of cylinder) - $100 = $1100 (owner to pay*)
* Does not include labour or installation costs
