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,  
connecting line, signal line are provided by users. Parameters are shown as below: 3×(1.0-1.5) mm2;  
parameters for signal line: 2×(0.75-1.25)mm2( shielded 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
