INSTALLATION & OWNER’S MANUAL
Thank you very much for purchasing our product,
Before using your unit, please read this manual carefully and keep it for future reference.
ALL IN ONE Type Air-source Heat Pump Water Heater
HOT WATER CAN BE DANGEROUS
Warning – Hot water burns. As a safety precaution, young children should always be supervised around
hot water fixtures.
Heat pump water heaters can store water at temperatures that can cause scalding. Water temperatures
over 50°C can scald and care needs to be taken to ensure that injuries do not occur through incorrect
use of your water heater.
As heat pump water heaters can generate water temperatures in excess of 60°C, regulations require
that a tempering valve be fitted to the heater to prevent water temperatures going to the home exceeding a preset safe maximum. The tempering valve must be connected to the hot water outlet line from
the water heater. The valve must be fitted by an authorized plumber at the time of installation or in retrofitting to existing systems.
Care should be taken to avoid coming into contact with any pipe work or fixtures associated with the
water heater pipe lines.
Under NO circumstances should any ‘home handy man’ type modifications be
attempted.
• This appliance is not intended for use by persons (including children) with reduced physical sensory
or mental capabilities, or lack of experience and knowledge, that prevents them from using the appliance safely without supervision or instruction. Children should be supervised by a responsible
person for their safety to ensure that they do not play with the appliance.
• 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.
•
THE INSTALLATION MUST COMPLY WITH THE REQUIREMENTS OF AS/NZS 3500.4, AS/NZS 3000, and
all local codes and regulatory authority requirements. In New Zealand, the installation must conform
to the New Zealand Building Code G12.
The power supply must be protected by an individual circuit breaker at the main electrical supply
switchboard and rated to suit the booster size. The supply to the heat pump water heater can be operated directly from the switchboard or via a remotely mounted switch or time clock as requested by the
customer. The heater must be provided with a suitable means for disconnecting the power supply.
WARNING
This unit is required reliable earthing
before usage, may otherwise result in
death or injury.
If you can't make sure that your house power supply is earthed
well, please don't install the unit.
The unit must be installed by a licensed tradesperson and in
accordance with：
•
Midea installation instructions.
•
AS/NZS 3500.4-"National Plumbing and Drainage Code Hot
Water Supply Systems-Acceptable Solutions".
•
AS/NZS 3000-Wiring Rules.
•
Local authority regulations.
•
Buliding Codes of Australia
•
Local Occupational Health and Satety (OH&S) Regulations.
This water heater must be installed by a licensed person as required by the Building Act. Only a

1. BASIC OPERATION PRINCIPLE
We know from experience, the natural flow of heat, moves from a
higher to a lower temperature source, a heat pump can transfer heat
from a lower temperature source to a higher temperature source with
high efficiency.
The advantage of a heat pump water heater is that it can supply more
heat energy,
normally 3:1 times than input electricity power by
extracting the heat from ambient atmosphere in a free-of charge way
and transfer to Sanitary Hot Water. Compared to a traditional water
heater, such as electric water heater or gas burner water heater, their
efficiency is normally less than 1:1, which means you can dramatically
cut off the bill of family daily SHW by the application of heat pump
water heater, the following examples will show more details.
Power consumption comparison under the same condition to heat 1
ton of water from 15˚C to 55˚C.

3. BEFORE INSTALLATION
3.1 Unpacking
3.1.1 Accessories
3.1.2 How to transport
1) In order to avoid scratching or deforming
the unit surface, apply guard boards
to the contacting surfaces.
No contact of fingers and other things
with the vanes.
Don’t incline the unit more than 75°
in moving, and keep it vertical when
installing.
2) This unit is heavy, it needs to be carried by two or more persons,
othewise might cause injury and damage.
3.2 Location requirements
1) Enough space for installation and maintenance should be
preserved.
2)
The air inlet and outlet should be free from obstacles and strong
wind.
3) The base surface should be flat, surface should be inclined no
more than 2° and able to bear the weight of the unit and suitable
for installing the unit without increasing noise or vibration.
4) The operating noise and air flow expelled should not affect
neighbors.
5) No flammable gas nearby.
6) It should be convenient for piping and wiring.
7)
If it is installed in indoor space, it might cause indoor temperature
to decrease and noise, Please take preventive measures for this.
8) If the unit has to be installed on a metal part of building, make
sure the electric insulation meets the relevant local electric
standard.

Gradient limit>75°
CAUTION
● The earthing pole of socket must be well grounded, make sure
that power supply socket and plug are dry and connected tightly.
●
Before cleaning, be sure to stop the operation and turn the
breaker off or pull out the power plug. Otherwise, an electric
shock and injury may be caused.
● Water temperature over 50℃ can
cause severe burns instantly or
death from scalds.
Children,
disabled and elderly are at
highest risk of being scalded.
Feel water before bathing or
showering. Water temperature
limiting valves are required as
per AS 3500.
● Do not operate the unit with a wet hand. An electric shock may
be caused.
● The installation height of power supply should be over 1.8m, if
there is any water exposure, steps must be taken to separate
the power supply from water.
● A one-way valve must be installed on the water inlet side, as
well as an isolation value.
● It is normal for some water to be released from the PTR valve
during operation. But, if there is a large volume of water, call
your service agent for instructions.
After long term use, check
the unit base and fittings. If damaged, the unit may sink, resulting
in injury. Arrange the drain pipe to ensure smooth draining.
Improper drainage work may cause wetting of the building,
furniture etc. Do not touch the inner parts of the controller or
remove the front panel. Some parts inside are dangerous to
touch, and damage may be caused.
●
Do not turn off the power supply.
System will stop or restart heating automatically. A continuous
power supply for water heating is necessary, except service
and maintenance.
Hydrogen gas is extremely flammable, and may build up if no
water is drawn of for several weeks.
To reduce the risk of
injury under these conditions, it is recommended that the hot
water tap is opened for several minutes at the kitchen sink
before using any electrical appliance connected to the hot
water system. When hydrogen is present, there will probably
be an unusual sound such as air escaping through the pipe as
the water begins to flow. There should be no smoking or open
flame near the tap at the time it is open.

Installation & Owner‘s Manual
3.4 If installed in inclosed space
The water heater must be located in a space >15m³, and must have
unrestricted air flow. As an example, a room that has an 2.5 tall
ceiling and is 3 meter long by 2 meter wide would contain 15m³ .

3.3 Maintenance space requirements (unit: mm)
● The ambient air temperature must also be considered when
installing this unit, in heat pump mode the ambient air temperature must be above 5℃ and below 43℃.If the ambient air
temperature falls outside these upper and lower limits,the
electrical elements will activate to meet the hot water demand
and the heat pump will not operate.
●
The unit should be located in an area not subject to freezing
temperatures. A unit located in unconditioned spaces (i.e.,
garages, basements, etc.) may require the water piping, condensate piping, and drain piping to be insulated to shelter agianst
freezing.
