Safety devices
Your cylinder is fitted with a:
• Temperature & Pressure
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.
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.
Draining and filling 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,

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
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 Recommended action
Error code is
flashing on the
controller
Error codes are indicated by the maintenance logo, a flashing
background light, and the error code number.
Take a note of the error code and phone Rinnai Customer Services
(0800 746 624) for advice on whether a plumber or electrician is
required.
No display on the
controller, but
power is on and
you have hot water
Call Rinnai Customer Services (0800 746 624).
Nothing happens
when the buttons
are pressed
Check if the child lock is set. Unlock by pressing the mode and -
buttons at the same time for more than three seconds.
I have cold
water while in iQ
automatic mode
A sudden significant increase of hot water consumption may
generate occasional cold water. Change to manual mode and select
the desired temperature level and then go back to iQ mode.
If this occurs regularly, increase the level in iQ mode or occasionally
go into manual mode.
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.

Rinnai Smart Cylinder MP indoor stainless steel: Owner & installer guide: 20430-C 03-17 | 9
Problem Recommended action
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.
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:
• Is your controller set correctly
• 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?
Resetting the Smart Control (only do as a last resort)
Press and hold the + and - buttons at the same time for five seconds or more. Only do this
as a last resort. If you reset during normal operation it will lose all the water usage history as
well as the memory setting and will default back to the preset factory setting of iQ automatic
mode, level setting three.

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 as per AS/NZS 3500.4:2015 5.4 and
G12/AS1 6.11.3.

Storage and delivery temperatures
Storage temperature: Biosafe operation
To meet the New Zealand Building Code requirement1to disinfect water for legionella bacteria,
the system will perform heating above 60 °C whenever risk conditions (<60 °C for 21 days) are
detected.
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.
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
Rinnai cylinders 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
Rinnai stainless steel cylinders 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 Rinnai stainless steel cylinders 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) CO2pH 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)

Rinnai Smart Cylinder MP indoor stainless steel: Owner & installer guide: 20430-C 03-17 | 17
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. Disconnect all power prior to installation and
commissioning.
• The water heater must be filled 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 fixing screws.
Connect all Live, Neutral and Earth 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.
