INSTALLER
Please leave this guide with the owner as it contains important safety and warranty information.

About the water heater

Water is heated by an electric element located in the cylinder. The temperature of the water is controlled by an automatic thermostat, factory preset at 75 °C.

Important
Where there is potential of damage occurring from leaking water, a suitably drained safe tray or bund is required.

Rinnai accepts no liability for damage caused by leaking cylinders.

Safety messages

Element cover
Do not remove the element cover as this will expose 230 V wiring, must only be removed by authorised person.

Thermostat setting
Must only be adjusted by an electrician or other suitably qualified tradesperson.

Damaged components
If any component is damaged, including the supply cord, 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
The 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.

DANGER
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
To meet the New Zealand Building Code requirement¹ to disinfect water for legionella bacteria², the cylinder thermostat has been set to 75 °C.

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 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.

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.

¹ Clause 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

Maintenance and servicing

Hot water systems require regular maintenance and servicing. To ensure longevity of your cylinder we recommend the following.

elements and anodes
Every 24 months after year five| Inspection and service the entire hot water system, including elements and anodes

• 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.

DANGER
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.

Anodes in enamel tanks
Storage tanks manufactured from metal can be susceptible to corrosion. The combined effects of water pressure, temperature, and water chemistry can create an aggressive environment for corrosion of some materials. For this reason anodes are placed in enamel tanks so as to corrode first. Anodes should be changed every five years or more frequently in hard or aggressive water areas.

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 RINNAI (0800 746 624).

How to operate the easing gear
GENTLY lift until water flows from the drain line, lower GENTLY to release.

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.

INSUFFICIENT OR NO HOT WATER

Cylinder power turned off| Check to ensure the electric isolating switch at the switchboard, usually marked ‘Hot water’ or ‘water heater’ is turned on.
Excessive hot water consumption| Often people are surprised at the amount of hot water used, especially when showering. If the amount of hot water used during the day exceeds the storage capacity of the cylinder, it is likely there will be insufficient hot water.
Temperature & Pressure Relief (TPR) valve continually discharging water| It is normal that this valve allows a small quantity of water to be discharged during the heating cycle. If it discharges more than a bucket of water during a 24 hour period or discharges continuously there may be another problem.

If the valve dribbles continuously, try easing the valve for a few seconds as described on the previous page. This may dislodge any foreign matter and alleviate the problem.

If the valve discharges at high flows, especially at night, it may be as a result of the water pressure exceeding the design pressure of the system. Contact your installer about fitting a Pressure Limiting Valve (PLV).

Expansion Control Valve (ECV) continually discharging water| It is normal that this valve allows a small quantity of water to be discharged during the heating cycle. If it discharges more than a bucket of water during a 24 hour period or discharges continuously there may be another problem.

If the valve dribbles continuously, try easing the valve for a few seconds. This may dislodge any foreign matter and alleviate the problem. If this does not solve the problem contact your installer or Rinnai.

NO WATER FROM THE TAP
Restriction in the hot tap or failure of the cold water supply to the water heater| Check for water flow at the other taps and that the cold water isolation valve is fully open.
HIGH ELECTRICITY BILLS
Excessive hot water consumption| Refer ‘Insufficient or no hot water’.
High electricity tariffs| The electricity tariff will determine the running costs of the system. Refer to your latest bill or contact your electricity provider to confirm what plan you are on and what you are paying.
Higher cylinder element usage| In extremely cold conditions the cylinder element may be operating more than normal.
WATER FLOW FLUCTUATIONS
One or more taps opened at the same time| More than one or two hot taps in use at the same time may cause a decrease in the hot water flow.

Is there more than one or two hot taps open, or are appliances such as a dishwasher or washing machine, in use at the same time.

Plumbing setup

Cylinders should be installed in accordance with G12/AS1 or G12/VM1 (AS/NZS 3500.4). Please allow sufficient room for access to covers and valves.

Seismic restraint
The tank must also be suitably restrained against seismic activity, ‘G12/AS1 Figure 14’ or AS/NZS 3500.4 Fig 5.4.4 details acceptable methods of constraint.

Safe tray
Where there is potential of damage occurring from leaking water, a suitably drained safe tray or bund is required. Rinnai accepts no liability for damage caused by leaking cylinders.

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 heater supply pressure.

Provision must be made to drain the cylinder.

All hot water pipe work should be insulated with polyurethane foam or equivalent insulation to optimise performance and energy efficiency.

DO NOT drill anything into the water heater, this can damage critical components and cause corrosion.

Pressure reducing valve
If the water supply pressure exceeds the rated pressure, a pressure reducing valve is to be fitted in the installation.

Discharge pipe
A discharge pipe connected to the pressure relief device is to be installed in a continuously downward direction and in a frost free environment.

The water may drip from the discharge pipe of the pressure-relief device and that this pipe must be left open to the atmosphere.

Storage and delivery temperatures

Storage temperature
To meet the New Zealand Building Code requirement¹ to disinfect water for legionella bacteria, the cylinder thermostat has been preset to 75 °C.

• The access cover to the element and the thermostat must only be removed by an electrician or other suitable qualified tradesperson.
• Thermostat settings must only be adjusted by an electrician or other suitably qualified tradesperson.

Hot water temperatures
NZBC G12.3.6 states that “Where hot water is provided to sanitary fixtures and sanitary appliances, used for personal hygiene, it must be delivered at a temperature that avoids the likelihood of scalding.”

In order to prevent scalding the delivered hot water temperature at any sanitary fixture used for personal hygiene shall not exceed:

• 45°C for early childhood centres, schools, aged care, institutions for people with psychiatric or physical disabilities, hospitals; and
• 55°C for all other buildings² (Note: AS/NZS 3500.4 which is cited in G12/VM1 has a maximum temperature of 50°C).

Sanitary fixtures used for personal hygiene includes showers, baths, hand basins and bidets.

In kitchens and laundries, heated water must be delivered to fixtures and appliances at flow rates and temperatures which are adequate for the correct functioning of those fixtures and appliances. The temperature required may be greater than 55°C.

To comply with these requirements, a temperature limiting device, such as a tempering or thermostatic mixing valve will be required on all installations.

Electrical supply and connections

The electrical connection must be carried out by a qualified person in accordance with NZ Electrical Regulations.

In its standard configuration the water heater will have three elements connected. The elements are intended to be connected to an AC 3-phase, 400 V, 50 Hz power supply in a four wire star-connected configuration.

In some installations, such as a heat pump or Rinnai INFINITY ring main applications, where the water heater is used as a ring main re-heater, the lowest element only may be connected (A1) to an AC single-phase, 230 V power supply.

• 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, refer table below.
Disconnection incorporated in the fixed wiring is in accordance with AS/NZS 3000.
