Introduction
Thanks for choosing OptiTech air source heat pump for your hot water. Please read this
manual carefully before installation and operation.
Working Principle
The heat pump water heater system heats water by transferring the heat from the
surrounding air to the water using a refrigerant. The refrigerant is heated by a heat
exchanger that absorbs heat from the surrounding air (Figure 1).
Note:
The unit must have a minimum of 5 hours continuous power available at all times to allow
the unit to operate without affecting reliability.

the air inlet (fins)/air outlet of the heat
pump unit.
Attention!
Rotating
Object!
Could result
in injury.
5
Caution
Do not climb or put anything on top of the
unit. Do not apply any force to the piping.
Could result in injuries
from a fall or being
scalded.
Do not use the heat pump unit if the
supplied installation blocks have been
damaged.
Do not put anything susceptible to humidity
under the heat pump unit.
Water could drain
out. In addition,
condensation could
drop from the pipe
connections.
Ensure adequate ventalation at the exhaust
outlet for optimal performance.
Do not block the air inlet and outlet.
Could harmfully
influence performance and lead to
failure.
Remove any snow form the units after snowfalls.
Snow building up
around the heat pump
unit and hot water
storage tank unit could
result in malfunction
and failure.
Check the installation conditions of the unit.
Installation of the unit in the following places could result in accidents or failure and the performance of the
unit not being guaranteed:
Anywhere the lowest temperature reached is -8◦C.
Anywhere not completely flat, unstable or where drainage is difficult.
Ensure not to put anything around the heat pump unit. Could result in poor performance and
unexpected problems.
In winter in particular, please pay attention to any snow or frost.
Optitech do not supply installation blocks
or mounting hardware.
6
Caution
Do not use the shower or any hot water for
at least one minute after recovery from a
power cut.
Hot water may
unexpectedly exit from
the shower.
When using the pressure relief valve, be
aware of extremely hot water discharging
In the event of any abnormality, turn the
hot water breaker switch to “OFF”
Do not install the unit anywhere it will be
exposed to seawater.
WARNING:
THIS APPLIANCE DELIVERS WATER AT A
HIGH TEMPERATURE.
DANGER:
Failure to operate the relief valve at least
once every six months may result in the tank
exploding. Continuous leakage of water from
the valve may indicate a problem with the
water heater.
7
SAFETY PRECAUTIONS
The appliance is intended to be permanently connected to the water mains and not connected by a hose-
set.
Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
The appliance shall be installed in accordance with national wiring regulations.
DANGER: The operation of the thermal cut-out indicates a possibly dangerous situation. Do not reset the
thermal cut-out until the water heater has been serviced by a qualified person.
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 with the water
heater.
If the water supply pressure exceeds the rated pressure, a pressure reducing valve is to be fitted in the
installation.
The water may drip from the discharge pipe of the pressure-relief device and that this pipe must be left
open to the atmosphere;
The pressure-relief device is to be operated regularly to remove lime deposits and to verify that it is not
blocked.
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 maximum inlet water pressure is 0.5MPA, and the minimum inlet water pressure is 0.1MPA. If the
maximum inlet water pressure is exceeded, a pressure reducing valve needs to be added.
Installation
This OptiTech hot water heat pump system must be installed by a licenced person in consideration
of the following standards and regulations:
•AS/NZS 3500.4 National plumbing and drainage code hot water supply systems – acceptable
solutions.
•HB 263-2004 Heated water systems plumbing industry commission.
•AS/NZS3000 Electrical installations (known as the Australian/New Zealand wiring rules).
•Notice to Victorian customers from the Victorian Plumbing Industry Commission, the Victorian
Building Act 1993 requires that this OptiTech heat pump water heater system must be installed by
a licenced person. Only a licenced person will provide a compliance certificate showing that the
work complies with all the relevant standards. Only a licenced person will have insurance
protecting their workmanship.
•The unit has been specifically designed for domestic hot water heating and may not be suitable
for any other purpose.
•The unit is designed to operate when connected to the town water supply with an operating
pressure rated at 500kPa. To ensure the mains pressure does not exceed this, a pressure-limiting
device that complies with AS1357 can be connected to the town water supply line, but is not
essential.
•This system delivers hot water exceeding 55°C. Reference should be made to AS/NZS 3500.4
and/or local regulations relating to the need for temperature tempering devices.
•The unit must be stored and transported in an upright position. Failure to do so may render the
unit faulty. Such failure is not covered under any warranty agreements. Failure to comply with the
above conditions will void the warranty.
•Clean the nozzle with foam water, and fasten the PTR with a profiling tool. Apply a circle of
anaerobic glue evenly on the threads with more than 3 turns at the starting point of the safety
valve thread, and the threads must be covered with anaerobic glue; the PTR valve outlet faces
down to the ground, and the left and right deviation in the vertical direction does not exceed 15° ,
the thread of the PTR valve shall be screwed in at least 4 threads.
•The effect that the installation shall conform to the Plumbing Code of Australia (PCA).
8
•Installation should comply with the Australian Plumbing code AS/NZS 3500.4
•Magnesium rod should be checked regularly annually and replaced in time.
•Recommended Thermostat setting EG (55℃ to match the AS 4234
parameters) Figure 2: Typical Installation Layout

Trouble Shooting Guide
If there is any problem in the operation of the heat pump, please check the following things prior
to calling for support:
STATUS
POSSIBLE CAUSES
TREATMENT MEASURES
Low or no hot water is left in the
storage tank.
Stop using hot water and wait for about an
hour.
Consider a change of the electricity supply
from off-peak mode (length of power supply
hours may be too short for the water
heating cycle to cover the hot water
consumption).
No hot water
comes out of
water tap
Air removing procedure from the
heat pump system may be
insufficient.
Open the water drain plugs on the heat
pump unit to remove air from the water
circuit. (be careful of burning).
Filter on cold inlet connector
may be blocked.
Check the filter and remove if there is any
blockage.
Temperature
of hot water is
too low
Water flow speed may be
dropped due to the heat pump
piping being bent, crushed or
blocked.
Check if any of the piping is bent or
crushed. Remove any kinks if possible.
Pipes may be frozen.
If frozen area is found on the piping, melt
the ice on the pipe and provide a heat
insulation.
Stop valve is closed.
Open the valve.
Air absorption is not sufficient
due to a blockage on the
evaporator.
Remove the object blocking the air flow
through the evaporator (e.g. Fallen leaves,
grass, snow, etc.).
For those problems not listed in the list above, an inspection provided by a skilled engineer is required.
Please contact the distributor.
Caution:
Do not shut down the electricity supplied to the heat pump system even if you go away from home and
hot water is not in use for a long time. (Do not turn off!)
