About your cylinder
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.
• Thermostat setting
Must only be adjusted
by an electrician or
other suitably qualied
tradesperson.
• 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 tted with a:
• Temperature & Pressure
and Relief (TPR) valve,
designed to automatically
release water in the
event that temperature
or pressure exceeds safe
levels.
• 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 qualied person.
Do not operate the system
unless all the safety devices
are tted and are in working
order. It is also important that
you do not tamper or remove
any of these devices.
Cylinder thermostat setting
To meet the New Zealand
Building Code requirement1to
disinfect water for legionella
bacteria2, the thermostat has
been set to 65 °C.
Turning the cylinder on/o󰀨
If you plan to be away for a
few nights we suggest you
leave the system switched on.
If it is necessary to switch it
o󰀨, when switching back on,
remember that the cylinder
will take time to heat back up
again.
Draining and lling the
system
This normally occurs during
installation or servicing and
must be carried out by an
authorised person.
Installation by a licensed
tradesperson
Only a licensed tradesperson
can install, adjust, maintain,
and service this water heater.
Any work carried out by a
non-licensed tradesperson
is illegal and will void any
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 this.
* Refer to the warranty terms and conditions in this guide for more information.
1Clause G12.3.9, Acceptable Solution G12/AS1 6.14.3
2 Legionella is a bacterium that can cause Legionnaires’ disease―a severe form of pneumonia
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.

MP indoor stainless steel cylinders: Owner and installer guide: 20132-I 09-20 | 5
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) operate the easing gear
Year ve Inspection and service the entire hot water system, including element*
Every 24 months after
year ve
Inspection and service the entire hot water system, including element*
* In hard water areas the element(s) must be periodically descaled. To do this the cylinder 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
ve years, or more
frequently in areas
where the water is
classied as hard.
A TPR valve must not be
replaced with one that has a
higher pressure rating than
that specied 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 ow 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 signicantly
more than the rates mentioned you may want to consider installing a low ow
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 is 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 tari󰀨 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.

Pressure limiting (reducing) valve
This water heater MUST be installed with a
500 kPa or less pressure limiting valve and
appropriate cold water expansion valve.
TPR valve
A temperature and pressure relief valve is
supplied with the water heater and MUST be
tted. A TPR insulation kit, to reduce heat loss,
is also supplied with the larger 250 and 300 L
cylinders—this also needs to be tted.
The TPR valve thread should be sealed with
teon tape, do not use paste and hemp. Use
the spanner ats on the valve body to tighten,
DO NOT use a wrench on the valve body.
The TPR valve must be tted with a drain pipe
to direct any water discharged to a visible point
outside the property. The drain pipe must have
a continuous fall and be at least the same size
as the TPR valve outlet (½ ˝BSP). Where the
drain pipe exceeds three metres in length it is
recommended an air break be provided within
300 mm of the TPR valve outlet. Where an air
break is used it is recommended that the pipe
size after the air break be increased to one
size larger than the TPR valve. It must also be
protected from freezing conditions.

Base requirements
Cylinders should be installed on a at level base of su󰀩cient 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 tted)
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 tted as per AS/NZS 3500.4:2015 5.4 and
G12/AS1 6.11.3.
Pipe work
It is the installer’s responsibility to adequately size the distribution pipe work in a property to ensure
su󰀩cient performance from all outlet ttings. 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 o󰀨 tap or line must be tted 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 e󰀩ciency.
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.
Storage and delivery temperatures
Storage temperature
To meet the New Zealand Building Code requirement
1
to disinfect water for legionella bacteria, the
cylinder thermostat has been set to 65 °C.
Thermostat settings must only be adjusted by an electrician or other suitably qualied
tradesperson. The access cover to the element and thermostat must only be removed by
an electrician or other suitably qualied tradesperson.
Sanitary xtures 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.

Water quality
Rinnai cylinders are manufactured to suit most NZ council water supplies. However
some water supplies can have a detrimental e󰀨ect on the water heater, its operation,
and life expectancy.
Pitting corrosion
Rinnai stainless steel cylinders are made from 2101 grade duplex stainless steel and 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.
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 and Impurity Limits
Most metropolitan water supplies fall within these limits. If you are unsure about water quality,
please test your water for compliance to Rinnai standards. If sludge or foreign matter is present in
the water supply, a suitable lter 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)
Stainless steel cylinders are not suitable for tank or bore water.

Electrical supply and connections
The electrical connection must be carried out by a qualied 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. Disconnect all power prior to installation and commissioning.
• The water heater must be lled with water prior to connection to the power supply
• 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 xing screws.
Connect all LIVE, NEUTRAL and EARTH wires in accordance with the wiring diagram. Inspect and
ensure all wiring links are secure prior to xing 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 xed wiring which has a cross-sectional
area of 1.5 mm2 - 2.5 mm2.
