About the Rinnai Heat Pump

The Rinnai Heat pump is a very efcient

water heater that can signicantly

reduce energy consumption as

compared to an electric storage system.

The principle of its operation is very

similar to the operation of a refrigerator,

but in reverse. There is latent heat

energy in the air and this is transferred

to the heating system and the water.

The warmer the climate in which it is

installed, the more efcient the heat

pump system will be at heating water.

Heat Pump Installation

While heat pumps work best in warmer

climates, they will continue to work in

cooler areas.

The map below shows the cooler areas

of Australia shaded in gray.

In these cooler areas, consumers may

experience longer hot water heat-up

times in winter. Because the efciency

benets of heat pumps in these

conditions is reduced compared to

other hot water systems, installation

of heat pumps in these areas is not

recommended.

Installation Instructions

4H4123 025961 Rev. A July 2012

Installation and Owner’s Manual – Heat Pump

Transport and Handling

Critical: 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 affect

product performance and

operation.

Step 1

• 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.

• The existing tank (if applicable)

should be drained and removed in a

responsible manner.

Never tilt unit more than

45˚ from vertical

Installation Instructions

Note: Do not commence

a job where the risks

cannot be controlled.

Note: Do not drain on to

grass or garden beds.

Placement of New Tank

Step 2

• The water heater must be installed

outdoors, close to the most

frequently used hot water outlet.

• Optimum installation location is on

the warmest side of house.

• The location must consider noise

impact on living areas. Avoid

positioning near bedrooms or

neighbours’ bedrooms. Although the

running noise level is very low (51

dB(A)) 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 overow tray

must be used where property

damage could occur from water

spillage. (See AS/NZS3500.4.2 for

further details.)

Note: The warranty does not

cover consequential damage

due to leakage of the water

heater.

Installation Instructions

Heat Pump

Install a plinth under the

water heater where the

water heater is subjected

to wet conditions

6H4123 025961 Rev. A July 2012

Installation and Owner’s Manual – Heat Pump

• Allow 200m3 of free space

surrounding the unit. This provides

clear ambient airow assisting the

product’s performance.

• The area must also be clear of debris

such as leaves and tree branches.

• Allow 700 mm clearance above and

150mm clearance to either side of

the unit as shown in the Rough-In

Diagram on page <?>.

• Ensure there are no obstructions

placed on top of the unit.

• Total clearance required from ground

to install unit is approximately

2410mm.

Plumbing Connections

Step 3

• Refer to the Rough-In Diagram on

page <?> for detailed information on

position of plumbing.

• An approved isolating valve, non-

return valve, line strainer (optional

but recommended), and union must

be tted between the supply main

and the RP¾/20 socket in the water

heater.

• All ttings must be approved by the

relevant installation Authority.

H4123 025961 Rev. A July 2012

Installation and Owner’s Manual – Heat Pump

• This water heater is designed for

direct connection to water supply

pressures of no greater than 800kPa.

• Where the mains pressure can

exceed or uctuate beyond 800kPa,

a pressure limiting device (complying

with AS1357) must be tted.

PTR Valve

• Connect the supplied PTR valve

into the top socket marked “RELIEF

VALVE” and discharge according to

plumbing regulations.

• PTR Valves for the unit are rated at

1000kpa.

• The drain line from this valve must

run in a continuously downward

direction with the discharge end left

permanently open to atmosphere.

Warning: A separate drain

line must be run for this relief

valve. It is not permitted to

couple drain lines from relief

valves into a single common

drain line.

• The PTR Valve is not intended to

enable connection of the water

heater to supplementary energy

sources such as solar panels or

slow combustion stoves (refer AS/

NZS 3500.4.2 for guidance on these

types of installations)

Cold and Hot Water Connections

• Connect the cold water pipe to the

storage tank, according to local

regulations and the Plumbing Code.

• The hot water line should be

connected to the hot water outlet.

Tempering Valve

• A tempering valve is mandatory.

• Ensure it is commissioned correctly.

Incorrect commissioning can lead to

a lack of hot water.

• We recommend using an orange

top Reliance brand tempering valve.

Condensation Drain Line

• A condensation drain line is required

to be tted to carry discharge clear

of water heater.

• Condensate drain line should not be

connected to the PTR Valve drain

line but can exit to the same point.

Insulation

• It is recommended that all hot

water lines are insulated with high

temperature, UV resistant 13mm

closed cell insulation.
