WARNINGS AND IMPORTANT INFORMATION
Rinnai 5 B Series Heat Pump OIM - Issue 1
TRANSPORT AND STORAGE OF APPLIANCE
RISK OF FIRE
The refrigerant used in the heat pump (R290 Propane) is a ammable gas.
The appliance(s) shall be stored and transported in an area without ignition sources (for example:
open ames, an operating gas appliance or an operating electric heater)
DO NOT pierce or burn the appliance�
Be aware that refrigerants may not contain an odour�
Compliance with AS/NZS 5149 MUST be observed while storing the appliance�
IMPORTANT
National and state regulations exist for storage, handling and transport of hazardous goods
including ammable gasses. The maximum number of pieces of equipment or the conguration
of the equipment, permitted to be transported or stored together will be determined by the
applicable regulations�
IMPORTANT
IMPORTANT
DO NOT TILT
MORE THAN 45°
FROM VERTICAL
45°
The Rinnai Electric Heat Pump must be transported at an angle no greater that 45º from vertical. As the compressor
unit is located at the top of the electric heat pump, should the heat pump be tilted at a greater angle than 45º from
vertical, the lubrication oil within the compressor can run down into the mufers. This will leave the compressor
motor without sufcient lubrication and lead to premature failure of the compressor unit.
As a general good practice it is better to keep the compressor upright as much as possible to avoid any risks.
Returning the Rinnai Electric Heat Pump to a vertical position will allow the oil to properly ow back into the
compressor motor.
Tilting the system beyond 45º from vertical will also place undue strain on compressor motor mounts and associated
piping.
WARNING
Do not use means to accelerate the defrosting process or to clean, other than those recommended
by the manufacturer�
The appliance shall be stored in a room without continuously operating ignition sources� For
example, open ames, an operating gas appliance or an operating electric heater.
Do not pierce or burn�
Be aware that refrigerants may not contain an odour�

able to turn on the tap)�
Installing tempering valves or thermostatic mixing valves which reduce the hot water temperature
delivered to the taps. Your local plumbing authority may already require that these be tted. Contact
your installer or local plumbing authority if in doubt�
NEVER….
Leave a toddler in the care of another child. They may not understand the need to have the water
temperature set at a safe level�
WARNINGS AND IMPORTANT INFORMATION
Rinnai 7 B Series Heat Pump OIM - Issue 1
OPERATING PRINCIPLE
The operation of an electric heat pump is very similar to a refrigerator, but in reverse. A heat pump operates by
transferring heat from the ambient outside air into the water. Electricity is just used to operate the system, but not
to directly heat the water. Because of this energy consumption is signicantly reduced as compared to an electric
element hot water system. The warmer the climate in which the heat pump is installed, the more efcient the heat
pump system will be at heating water.
The heat pump unit includes highly efcient micro-channel heat exchanger wrapped around the inner cylinder
for thermal conductivity. A temperature sensor in the tank is used to control the heat pump operation to achieve
suitable tank temperature.
During the occasional times when the ambient weather conditions are not suitable for the heat pump to operate,
the electric element will provide heating to ensure a supply of hot water.

WARNINGS AND IMPORTANT INFORMATION
Rinnai 8 B Series Heat Pump OIM - Issue 1
SAFETY DEVICES
The water heating system is supplied with various safety devices including temperature sensors, overheat sensors
and switches and a Pressure & Temperature Relief (PTR) valve. These devices must not be tampered with or
removed. The water heating system must not be operated unless each of these devices is tted and is in working
order.
WARNING
DO NOT tamper with or remove safety devices�
DO NOT operate the water heater unless all safety devices are tted and in working order.
DO NOT block or seal the PTR Valve and drain pipe�
Pressure & Temperature Relief (PTR) Valve
This valve is located near the top of the water heater and is
essential for safe operation. It is normal for the valve to release
a small quantity of water through the drain line during heating.
However, continuous leakage of water from the valve and its
drain line may indicate a problem with the water heater.
WARNING
NEVER block the outlet of the PTR valve or it’s drain line for any reason� The easing gear MUST
be operated at least every 6 months to remove lime deposits and verify that it is not blocked�
Failure to do this may result in the water heater failing�
If the valve does not discharge water when the easing gear lever is opened, or does not seal again
when the easing gear is closed, attendance by an authorised person MUST be arranged without
delay� The PTR valve is not serviceable�
EXCESSIVE DISCHARGE FROM SAFETY DEVICES
Pressure & Temperature Relief (PTR) Valve
It is normal and desirable 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 gear for a few seconds as described above. This may
dislodge any foreign matter and alleviate the problem.
If the valve discharges at high ows, especially at night, it may be as a result of the water pressure exceeding the
design pressure of the water heater. Ask your installer to t a Pressure Limiting Valve (PLV).
WARNING
NEVER replace the PTR valve with one which has a higher pressure rating than is specied for
your water heater�
Expansion Control Valve (ECV) - if required
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 leaks continuously, try easing the valve gear for a few seconds. This may dislodge any foreign matter
which may be causing the problem. If this does not x the issue, contact Rinnai.
Operate the easing gear regularly to remove any lime deposits and to verify that it is not blocked.

WARNINGS AND IMPORTANT INFORMATION
Rinnai 9 B Series Heat Pump OIM - Issue 1
HYDROGEN GAS
If the hot water unit is not used for two weeks or more, a quantity of hydrogen gas, which is highly ammable,
may accumulate in the water heater. To dissipate this safely, it is recommended that a non electrically operated
hot tap be turned on for two minutes at a sink, basin, or bath, but not a dishwasher or other appliance. During
this procedure there must be no smoking, open ame or any electrical appliance operating nearby. If hydrogen is
discharged through the tap, it will probably make a sound like air escaping.
ANODES
The water heater is tted with sacricial anodes to extend it’s life. They will slowly dissipate whilst protecting the
cylinder. The life of the water heater may be extended by arranging for an authorised person to inspect the anodes
and replace them as required. It is recommended that the anodes be inspected at least every 5 years. The factory
tted Rinnai anodes are Magnesium based. These anodes are suited to conditions where the total dissolved solids
(TDS) content in the water supply does not exceed 600 mg/L, (which is the case in most areas). In areas where
the total dissolved solids (TDS) content in the water supply exceeds 600 mg/L Rinnai aluminium based anodes
are required.
TURNING OFF THE WATER HEATING SYSTEM
If you plan to be away for only a few nights, we suggest you leave the water heating system switched on. If it is
necessary to switch off the water heater, do so as outlined below:
DO NOT turn power o to the heat pump unit if snow or frost conditions are expected as components
in the system may be damaged by freezing. If power needs to be turned o or power failure occurs
and freezing conditions are expected, the water needs to be drained from the heat pump unit.
Follow the procedure described below in the section ‘Draining and Filling’�
TURNING ON THE WATER HEATING SYSTEM
Switch on the electric supply to the heat pump unit. Water heating will now occur as required. It may take a number
of hours before hot water is available.
DRAINING AND FILLING
Draining or lling of the complete system normally only occurs during installation or servicing and must be carried
out by an authorised person.
Draining water from the heat pump unit is necessary if the power will be shut off to the unit and snow or frost
conditions are expected. Arrange for an authorised person to carry out this task�
To drain the heat pump:
1. Turn off power to the heat pump
2. Close the cold water mains supply stop cock
3. Open a hot tap to relieve pressure
4. Disconnect the hot outlet near the top of the storage cylinder
5. Disconnect the cold inlet near the bottom of the storage cylinder.
6. The system will now drain completely.
MAINTENANCE AND REGULAR CARE
Operate the easing gear of the PTR and the ECV if tted as described in the section ‘Safety Devices’ on page 8.
The overow tray (supplied by installer) and drain underneath the storage cylinder (if tted) should be periodically
checked to ensure there are no blockages.
WARNING
DO NOT drill, screw or x any ancillary items to the of the tank. This product is tted with a high
eciency heat exchanger attached to the inner cylinder, anything penetrating the outer skin of the
tank may damage the heat exchanger�

(
OH&S
)
WARNING
Installation and commissioning MUST be performed by authorised persons�
The heat pump MUST be installed in accordance with these instructions and all regulatory
requirements which exist in your area including those in relation to manual lifting�
Applicable publications and regulations may include:
•
AS/NZS 3500 National Plumbing and Drainage
•
AS/NZS 3000 Wiring Rules
•
Building Codes of Australia (BCA)
•
Local Occupational Health and Safety (OH&S) regulations
This appliance is not suitable for use as a domestic spa pool or swimming pool heater�
Electric Heat pumps are heavy and bulky items� Australian States and Territories have a Principal
Occupational Health and Safety (OH&S) Act which contains requirements relating to the handling
of large, bulky or awkward items� Persons installing heat pump systems MUST be aware of
their responsibilities and be adequately trained and qualied, in accordance with local OH&S
requirements�
LOCATION
The electric heat pump can be installed externally or internally.
The electric heat pump should be placed as close as practicable to the most frequently used hot water outlet point
or points to minimise the delay time for hot water delivery. This will usually be the kitchen tap. For installations
where the distance between the heat pump and the outlets is considerable, a ow and return system can be used
which minimise the waiting time for hot water delivery.
It is recommended that all components are installed at ground or oor level with consideration for easy service,
repair or replacement access.. The heat pump MUST be installed in a vertically upright position. All components
MUST be accessible without the use of a ladder or scaffold. The unit MUST NOT be installed in roof spaces.
WARNING
Ensure the location complies with the requirements of AS/NZS 60335�2�40 & AS/NZS 5149�
The air inlet and outlet of the heat pump module MUST be away from areas with strong wind and MUST be
provided with sufcient clearances as per those shown in the section ‘Clearances’ on page 14.
The heat pump MUST be connected to an independent AC 240 V, 50 Hz power supply.
Ensure the pressure and temperature pressure relief (PTR) valve and any access covers have sufcient clearances
and are accessible for service and removal. The information on the rating plates MUST also be readable.
The heat pump MUST be installed free-standing on a level and stable base. The cylinder should be mounted on a
concrete base at least 50mm thick or on well-seasoned, evenly spread hardwood slats with a thickness of at least
25mm. Where property damage can occur as a result of water leakage, the storage cylinder MUST be installed
with a safe tray (overow tray) and drain in accordance with AS 3500.4. Ensure the storage cylinder DOES NOT
stand on wet surfaces.
Internal Installation
For internal installations the area MUST meet the following requirements:
•
Minimum room volume of 55m
3
per unit.
•
Good Ventilation (i.e minimum 280 L/s per unit)
•
Away from any ignition sources or corrosive environments.
If the heat pump is installed internally careful consideration should be taken in regards to positioning and limiting
the effect of unit noise and reverberation during operation.
Condensation
As this heat pump is highly efcient, the surrounding air temperature could be cooled by up to 4°C and condensate
formed, the condensate outlet will need to be plumbed to a suitable drain.
INSTALLATION
Rinnai 16 B Series Heat Pump OIM - Issue 1
Drainage
Where property damage can occur as a result of water leakage, the water heater MUST be installed with a safe
tray (overow tray) and drain. Construction, installation and draining of the safe tray MUST comply with local
regulatory requirements and. AS/NZS 3500.4 also requires the use of a safe tray for particular situations.
WATER SUPPLY
This appliance is intended to be permanently connected to the water mains and not to be connected by a hose set.
The maximum water pressure is listed on page 12. An approved pressure limiting valve may be required if the
maximum rated water supply pressure is exceeded.
Water chemistry and impurity limits are detailed in the separate warranty document. Most metropolitan water
supplies fall within these requirements. If you are unsure about water quality and suitability, contact your water
authority.
A water lter MUST be tted on the inlet to the tank to prevent sludge or foreign matter entering the system.
In a scaling water supply, calcium carbonate and possibly other compounds are deposited out of the water onto
any hot metallic surface and form a scale. Scaling water may cause scale deposits to form onto the metallic
surfaces of the PTR valve and may prevent it from operating properly. To prevent this, an expansion control valve
(ECV) MUST be tted on the cold water line after the non-return valve in areas of scaling water. ECVs’ MUST
be tted in South Australia and Western Australia to comply with local regulations.
STORAGE TEMPERATURE
To meet regulatory requirements the thermostat control on the heat pump water heater is factory pre-set to heat all
the water in the tank to 70°C once a week. This cannot be altered.
HOT WATER DELIVERY TEMPERATURE
This appliance may deliver water at high temperature. Refer to the Plumbing Code of Australia (PCA), local
requirements and installation instructions to determine if additional delivery temperature control is required.
The PCA, local regulations and the requirements of AS/NZS 3500.4 MUST be considered regarding the
temperature limitations of hot water supplied to areas used primarily for personal hygiene.
The temperature of water to certain areas is limited to different temperatures according to purpose, for e.g. early
childhood centres, primary and secondary schools and nursing homes or similar facilities for young, aged, sick
or people with disabilities and for all other buildings. To comply with these requirements, a temperature limiting
device, such as a thermostatic mixing or tempering valve, will be required on hot water systems.
VALVES AND FITTINGS
IMPORTANT
A 46 kW capacity, combined Pressure and Temperature Relief (PTR) valve is supplied with the
Heat Pump hot water system. This valve is tted at the top of the storage cylinder. The PTR
valve is a safety device and it is mandatory that it is tted by the installer in all installations..
The following valves & ttings are to be supplied by the installer:
•
A cold water expansion control valve (ECV). An ECV MUST be tted in Western Australia and South Australia
to the cold water supply to the storage cylinder to comply with local regulations. An ECV is recommended in
all other geographical areas where the water supply has a tendency to cause scaling. This will reduce hot
water discharge from the pressure and temperature relief (PTR) valve which minimises wear on this valve.
•
A stop cock, non return valve and line strainer. Combination valves incorporating two or more of these
functions (such as ‘Trio’ valves) are suitable. These are tted to the cold water supply to the storage cylinder

TRANSPORT AND HANDLING
IMPORTANT
When moving the unit, it MUST be close to vertical at all times�
When using a trolley to move the unit, ensure it is not tilted more than 45° from the vertical�
Non compliance will void warranty and severely aect product performance and operation
The Rinnai Electric Heat Pump MUST be transported at
an angle no greater that 45º from vertical.
As the compressor unit is located at the top of the electric
heat pump, should the heat pump be tilted at a greater
angle than 45º from vertical, the lubrication oil within the
compressor can run down into the mufers.
This will leave the compressor motor without sufcient
lubrication and lead to premature failure of the compressor
unit.
As a general good practice it is better to keep the
compressor upright as much as possible. Returning the
Rinnai Electric Heat Pump to a vertical position will allow
the oil to properly ow back into the compressor motor.
Tilting the heat pump beyond 45º from vertical will also
place undue strain on compressor motor mounts and
associated piping.
45°
Never tilt unit more than 45˚ from vertical
POSITIONING THE HEAT PUMP
Arrive at site and conduct a safety audit. Safety audits can also be known
as Work Method Statements (WMS) or Job Site Analysis (JSA).
Park your vehicle as close as allowable to your installation. Unload all
materials in a safe manner.
Position all materials in a convenient position near the work area.
Where the requirements for internal installation can’t be met, the heat
pump MUST be installed outdoors.
The location MUST consider noise impact on living areas. Avoid
positioning near bedrooms or neighbours’ bedrooms. Although the
running noise level is very low it can be expected that the heat pump will
run during the night.
Adequate access MUST be available to the relief valve and anodes.
Safely position the new unit on a level surface in accordance with all
plumbing and building regulations.
A properly drained overow tray MUST be used where property
damage could occur from water spillage. (See AS/NZS 3500.4.2 for
further details.)
NOTE
DO NOT drain on to grass or garden beds�
DO NOT commence a job where the risks cannot be
controlled�
Allow 200m
3
of free space surrounding the unit. This provides clear
ambient airow assisting the product’s performance. Ensure the
clearance requirements specied in the section ‘Dimensions’ on page
13. are complied with. The area MUST also be clear of debris such
as leaves and tree branches.
Install a plinth under the heat pump

INSTALLATION
Rinnai 18 B Series Heat Pump OIM - Issue 1
CONNECT THE PTR VALVE
Connect the PTR valve to the uppermost tting of the storage cylinder. See the diagram in the section ‘Dimensions’
on page 13.
The PTR pressure rating MUST be suited for the cylinder and adequate for the thermal loading applied to the
storage cylinder, as specied in the table on page 12. The supplied PTR valve input rating is 46 kW. The PTR
valve rating MUST EXCEED the total input from the heat pump (see the table on page 12). As this is less than
46 kW, the supplied PTR valve is of sufcient capacity.
Use PTFE (Teon) thread tape on the valve, never use hemp or other sealing materials. Ensure the tape does not
protrude past the end of the thread, which could result in it hanging over the end of the thread and blocking the
water passage through the valve.
Connect the supplied PTR valve into the top socket marked “Relief Valve” Leave the valve outlet pointing down.
Tighten the valve using the spanner ats - never use the valve. Discharge according to plumbing regulations. PTR
Valves for the unit are rated at 850 kpa.
The drain line from this valve MUST run in a continuously downward direction with the discharge end left
permanently open to atmosphere.
PLUMBING CONNECTIONS
Refer to the diagram on page 13 for detailed information on position of plumbing.
An approved isolating valve, non return valve, line strainer, and union MUST be tted between the supply main
and the RP ¾ socket in the water heater. All ttings MUST be approved by the relevant installation Authority.
An ECV MUST be tted in Western Australia and South Australia to the cold water supply to the storage cylinder
to comply with local regulations.
An ECV is recommended in all other geographical areas where the water supply has a tendency to cause scaling.
This will reduce hot water discharge from the Pressure and Temperature Relief (PTR) valve which minimises wear
on this valve.
This water heater is designed for direct connection to water supply pressures of no greater than those specied
on page 12. Where the mains pressure can exceed or uctuate beyond this, a pressure limiting (PLV) device
(complying with AS1357) MUST be tted.
CONNECT COLD / HOT WATER SUPPLY
Connect cold water supply, Pressure Limiting Valve (PLV) and or Expansion Control Valve (ECV).
Connect cold water supply to the storage tank (refer to Diagram BELOW).
A stop cock, non return valve and line strainer MUST be tted.
Connect the pipe work supplying hot water to the premises to the hot water outlet on the tank.
A temperature limiting device may be required as detailed in the section the section ‘Hot Water Delivery Temperature’
on page 16
It is recommended that all hot water lines are insulated with high temperature, UV resistant 13mm closed cell
insulation.

A condensate drain line is required to be tted to carry discharge clear of
the water heater.
The condensate drain line should not be connected to the PTR drain line
but can exit to the same point.
The diagram shows the condensate drain location on the heat pump. Use
the supplied PVC pipe (inner diameter 19mm, UV resistant) and clamp to
connect to the condensate outlet.
Independent 15mm copper pipes MUST be tted to the drain outlets of the
PTR and ECV.
Each pipe MUST be open to atmosphere and run with a continual downward grade in a frost free environment to
a visible discharge point.
Drain lines MUST not exceed 9 meters in length.
Valves or other restrictions MUST NOT be placed in the relief valve drain outlet line.

OPERATION OF CONTROLLER
When the heat pump turns on, the control system initiates and will check the unit’s operating parameters. The
controller will check on all sensors and pressure switches. If conditions are suitable (i.e all reading within the
reasonable range) and there is enough energy available in the surrounding air, the fan and compressor will turn
on. If not enough energy is detected in ambient air then the controller calls for the booster heating element to run.
There will be a delay from the time the heat pump is switched on before the fan and compressor begin operating.
The unit is self regulating so there are no internal adjustments to be made during commissioning. When the unit is
operated for the rst time, it runs through an initial heat up cycle, allow time for the initial heat up cycle. Depending
on the ambient conditions this can take several hours.
If for any reason the unit does not start, the water is cold and the controller unit is not displaying any LED lights, an
electrician should test that power is available to the heat pump.
