Trouble Shooting
The followings are not malfuncition
When the air conditoner is started, when the
compressor starts or stops during operation
or when the air conditioner is stopped,it som-
etimes sounds “ Bi- Bi-” or “Godo-Godo”. It is
the flowing sound of the refrigerant , not a
malfunction.
Water flowing sound is heard
Hua
Hua
This is caused by heat expansion or contra-
ction of plastics
Cracking sound is heard
It smells.
Air blown out from the indoor unit sometimes
smells. The smell results from smells of
furniture, paint , tobacco absorbed by indoor
unit.
During operation, white fog comes out of
indoor unit.

Electrical Wiring
Warning
Electrical construction should be made with specific mains circuit by the qualified personnel according
to the installation instruction. Electric shock and fire may be caused if the capacity of power supply
is not sufficient.
During arranging the wiring layout, specified cables should be used as the mains line, which accords
with the local regulations on wiring. Connecting and fastening should be performed reliably to avoid
the external force of cables from transmitting to the terminals. Improper connection or fastness may
lead to burning or fire accidents.
There must be the ground connection according to the criterion. Unreliable grounding may cause
electrical shocks. Do not connect the grounding line to the gas pipe, water pipe, lightening rod and
telephone line.
Attention
Only copper wire can be used. Breaker for electric leakage should be provided, or electric shock may
occur.
The wiring of the mains line is of Y type. The power plug L should be connected to the live wire and
plug N connected to null wire while should be connected to the ground wire. For the type with auxiliary
electrically heating function, the live wire and the null wire should not be misconnected, or the surface
of electrical heating body will be electrified. If the power line is damaged, replace it by the professional
personnel of the manufacturer or service center.
The power line of indoor units should be arranged according to the installation instruction of indoor units.
The electrical wiring should be out of contact with the high-temperature sections of tubing as to avoid
melting the insulating layer of cables, which may cause accidents.
After connected to the terminal tier, the tubing should be curved into be a U-type elbow and fastened
with the pressing clip.
Controller wiring and refrigerant tubing can be arranged and fixed together.
The machine can’t be powered on before electrical operation. Maintenance should be done while the
power is shut down.
Seal the thread hole with heat insulating materials to avoid condensation.
Signal line and power line are separately independent, which can’t share one line. [Note: the power line,

Concerning MRV Auto Restart function for H-MRV models
Haier Auto Restart function when the unit power drops down suddenly, the unit microprocessor will store the previous
working condition and when the power is on again, the unit will run as this memory.
Auto Restart function is designed basically on the MRV whole system, but it is suitable for each indoor unit individually.
If some of indoor units power cut down, but the outdoor unit and the other indoor units still work, maybe problems will
happen such as freezing at cooling mode and overload protection at heating mode on those indoor units without power.
Reason
When one or some indoor units power drops down and the other indoor units are still work, the indoor units without
the power, will keep the previous working condition before the power is off.
And expansion valve keeps open at a kind of opening rate condition as the previous requirement,so there is refrigerant
flowing in the exchanger, but the indoor fan stops working. If the units work at cooling mode, the indoor units without the
power will maybe make freezing. If the unit works at heating mode, maybe the outdoor unit compressor will stop because
of the pressure or temperature protection. This is our design basically on Auto Restart function currently.
Haier, Herewith, solemnly informs our customers, installers, distributors, etc. when making installation,
please make sure when the power is shut down whether artificially or accidentally, the whole system
including outdoor unit and all the indoor units must be off. If you do not make the installation as
our indication, Haier will not be responsible for any problem resulting from this.
Pay special care to the following and check after installation
