Your air conditioner may be subject to any change owing to the improvement of Haier products.
MRV series multi zone air conditioning systems can operate multiple indoor units in heating or cooling. When in cooling, only units set to cool will run. Same logic applies for heating.
Turn power on for 12 hours prior to start-up to allow the crankcase heater adequate time to protect the compressor. All indoor units on the same refrigeration system should use the unied power switch to ensure that all indoor units are all powered on during system operation.
Product Features
1.Hanging-style installation to save space;
2.Automatic display of faults;
3.Function of central control, wired control,wireless control (optional from our company).
4.The air conditioner is provided with the function of compensation for power supply. During operation, when the power supply fails emergently and resumes again, the air conditioner returns to the working condition before power failure, if provided with compensation function.
5.The operating methods and functions are same although the shapes of indoor units are different. Therefore, the outline drawing of MVAW007MV2AA indoor unit is taken as an example for illustration.
Warning
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualied persons in order to avoid a hazard.
• This equipment should not be used or serviced by personnel who have not been properly trained in its operation and maintenance.
• Children should be supervised to ensure that they do not play with the appliance.
• The appliances are not intended to be operated by means of an external timer or separate remote-control system.
• Keep the appliance and its cord out of reach of children less than 8 years.

Safety

• This manual should be saved and stored close to this air conditioning equipment.
• There are two types if indications. Both are related to safety and should be strictly followed. " issues that pose a risk of major injury or death. "
injury.
• After installation and start-up commissioning, please give the manual to the user. The manual should be kept in safe place and close to the unit.
Caution" highlights issues that pose a risk of equipment or bodily
Warning" highlights
WARNING
• Installation and maintenance should be performed by an authorized agency. The wrong operation of this air condition equipment may cause water damage, electric shock or re.
• Please install the unit on the top of a solid foundation or structure which is strong enough to support the unit.
• The installation of this condition equipment should follow local building codes.
• Use the right cable size, secure the terminal rmly, organize the cables well and make sure no tension is added on cables. Cable insulation should not be damaged. Improper wire installation may lead to re.
• This unit is only compatible with R-410A refrigerant. If any other gas enters the system, it may lead to abnormal high pressure which may cause damage or injury.
• Only use branches supplied by Haier. Use of any other branches will void warranty.
• Keep the condensate drain pipe away from toxic gas vents to prevent possible pollution of indoor environment.
• Care should be taken to ensure that there are no refrigerant leaks. R-410A is a heavy gas and will displace oxygen. Ventilate the area if a leak if found.
• The unit is not explosion-proof. Please keep it away from ammable gases.
• The drain pipe should be installed per this manual to ensure proper drainage. The pipe should be well insulated to avoid condensation. Wrong installation may lead to water damage.
• Both liquid pipe and the vapor pipe should be also well insulated. Not enough insulation may lead to system performance deterioration or condensate formation.
• This equipment should not be used or serviced by personnel who have not been properly trained in its operation and maintenance.
• Children should be supervised to ensure that they do not play on or near the equipment.
• Keep the appliance and its cord out of reach of children.
• The appliances are not intended to be operated by means of an external timer or separate remote-control system.
CAUTION
• Grounding wire should be connected to the grounding bar. The grounding wire cannot be connected to the gas pipe, water pipe, lightening rod or the telephone grounding wire. Improper grounding may cause electric shock.
• A circuit breaker should be installed. If not, it may cause electric shocks or accidents.
• After installation, the air condition equipment should be powered on and passed the electric leakage current lest.
• If the ambient humidity is more than 80%, if the water discharge hole is blocked or the lter becomes dirty or the airow speed changes, this may lead to condensate water leaks. There may also be some drops of water spraying out.

Safety
Items with this warning sign concerning the product’s safety and the personal security must be performed strictly.
Items with this forbidding sign refer to absolutely forbidden behaviors. If not, they may cause machine damage or endanger operator’s personal safety.
Clean the lter regularly. Cooling or heating performance will be degraded if the lter is blocked, resulting in large power consumption, failure, and water dripping at freezing.
Avoid cold wind from blowing out. During heating running, the fan of indoor units will not rotate immediately as to prevent cold wind from blowing out.
Regulating Wind Direction: It is recommended not to make the wind deector downwards for a long time to avoid condensation at air outlet port during refrigerating or dehumidifying. Water dropping might appear at the air outlet port in refrigerating or dehumidifying mode.
Don’t touch the outlet while the ap is moving. Don’t put anything in the grid in case danger may occur.
Changing Wind Speeds: In the state of refrigerating, with automatic blowing mode, the wind speed automatically decreases when the room temperature approaches the setting. In the state of heating, when the room temperature reaches the setting temperature the compressor stops working and the fan turns to low wind or stops. Wind speed changes automatically in the dehumidifying mode.
Defrosting: During heating running, the air conditioner would defrost automatically if there is frost on heat exchanger of outdoor units. Do not rotate fans of both indoor units and outdoor units during defrosting. After nishing defrosting, the air conditioner will resume running automatically.
The machine operation must be controlled by the control.
Hints: As air conditioners absorb heat from the environment and release it to the room, heating effects will be inuenced by the temperature in and out of the room.

Safety
Attention
• Do not put any heating apparatus under the indoor units. The heat may cause distortion of the units.
• Pay attention to the ventilation to avoid anoxic injury.
• Do not place an open ame in the path of blowing air.
• Do not install in a corrosive environment. If the base collapses, the unit may fall and cause damage, product failure, personal injury or death.
• 3-minutes protection To protect the unit, there is a 3-minute time-out after the unit stops or after power is applied.
• Close the window to avoid outdoor air getting in. Curtains or window shutters can be put down to avoid the sunshine.
• Do not touch the power switch with the wet hand to avoid power shock.
• Turn off the system and remove power when servicing the unit.
• Do not use the unit for special purposes such as preserving foods, works of art etc. It is an air conditioner for comfort cooling / heating, not a precision refrigeration system.
Notices during Operation
• Use the correctly rated breaker or fuse. Improper breaker or fuse may lead to re, electric shock, explosion, personal injury or death.
• Do not permit water or steam to enter the unit and the wired controller. There is risk of unit failure, re, electric shock, personal injury or death.
• Turn off the power to save energy if the unit will be not used for a long period. If the unit is not powered off, it will consume power.
• Don't remove power while system is running.
• Do not clean the unit with water spray. There is risk of unit failure, re, electric shock, personal injury or death.
• Keep ammable gas or combustibles away from the unit. There is risk of product failure, re, personal injury or death.
• Please keep children away from this air condition equipment.
