Indoor Unit Operation & Installation Manual

AS162MCAHA AS182MCAHA

MRV series multiple air conditioning systems adopt the consistent running mode, by which, all indoor units can only be heating or refrigerating operation at the same time.

To protect the compressor, the air conditioning unit should be powered on for over 12 hours before using it. All indoor units of the same refrigerating system should use the unified power switch to ensure that all indoor units are in the state of being powered on at the same time during the operation of air conditioner.

Your air conditioner may be subject to any change owing to the improvement of Haier products.

Please ask the special maintenance station for installation and repair. Water leakage, electric shocks or fire accidents might be caused from improper installation if you conduct the installation by your own. The installation should be conducted properly according to this manual. Water leakage, electric shocks or fire accidents might be caused from improper installation. Please make sure to install the air conditioner on the place where can bear the weight of the air conditioner. The air conditioner canít be installed on the grids such as the non-special metal burglar-proof net. The place with insufficient support strength might cause the dropdown of the machine, which may lead to personal injuries. The installation should be ensured against typhoons and earthquakes, etc. The installation unconformable to the requirements will lead to accidents due to the turnover of the machine. Specific cables should be used for reliable connections of the wirings. Please fix the terminal connections reliably to avoid the outside force applied on the cables from being impressed on the cables. Improper connections and fixings might lead to such accidents as heating or fire accidents. Correct shapes of wirings should be kept while the embossed shape is not allowed. The wirings should be reliably connected to avoid the cover and the plate of the electrical cabinet lipping the wiring. Improper installation might cause such accidents as heating or fire accidents. While placing or reinstalling the air conditioner, except the specific refrigerant (R22), donít let the air go into the refrigeration cycle system. The air in the refrigeration cycle system might lead to the cracking or personal injuries due to abnormal high pressure of the refrigeration cycle system. During installation, please use the accompanied spare parts or specific parts. If not, water leakage, electric shocks, fire accidents or refrigerant leakage might be caused. Donít drain the water from the drainpipe to the waterspout where may exist harmful gases such as sulfureted gas to avoid the harmful gases entering into the room. During installation, if refrigerant leakage occurs, ventilation measures should be taken, for the refrigerant gas might generate harmful gases upon contacting the flame. After installation, check if any refrigerant leakage exists. If the refrigerant gas leaks in the room, such things as air blowing heaters and stoves, etc. may generate harmful gases. Donít install the air conditioner at the places where the flammable gases may leak. In case the gas leakage occurs around the machine, such accidents as fire disasters may be caused. The drainpipe should be properly mounted according to this manual as to ensure the smooth drainage. In addition, heat preservation should be taken to avoid condensation. Improper drainpipe mounting might cause water leakage, which will get the articles at home wet. The refrigerant gas pipe and liquid pipe should be heat insulated to preserve heat. For inappropriate heat insulation, the water caused from the condensation will drop to get the article at home wet.

Warning

If the air conditioner is transferred to a new user, this manual shall be transferred to the user, together with the conditioner. Before installation, be sure to read Safety Considerations in this manual for proper installation. The safety considerations stated below is divided into ì Warningî and ì Attentionî. The matters on severe accidents caused from wrong installation, which is likely to lead to death or serious injury, are listed in ì Warningî. However, the matters listed in ì Attentionî are also likely cause the severe accidents. In general, both of them are the important items related to the security, which should be strictly abided by. After the installation, perform test run to make sure everything is in normal conditions, and then operate and maintain the air conditioner in accordance with the User Manual. The User Manual should be delivered to the user for proper keeping.

Attention

The air conditioner should be effectively grounded. Electric shocks may occur if the air conditioner is ungrounded or inappropriately grounded. The wire for earthing shouldnít be connected to the connections on the gas pipe, water pipe, lightning rod or telephone. The breaker for electricity leakage should be mounted. If not, accidents such as electric shocks may happen. The installed air conditioner should be checked for electricity leakage by being powered.

Safety Considerations

Items with this warning sign concerning the productís 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 operatorís personal safety.

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 influenced by the temperature in and out of the room.

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 finishing defrosting, the air conditioner will resume running automatically.

Regulating Wind Direction: It is recommended not to make the wind deflector downwards for a long time to avoid condensation at air outlet port during refrigerating or dehumidifying. W ater dropping might appear at the air outlet port in refrigerating or dehumidifying mode.

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.

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.

Clean the filter regularly. Cooling or heating performance will be degraded if the filter is blocked, resulting in large power consumption, failure, and water dripping at freezing.

Donít touch the outlet while the flap is moving. Donít put anything in the grid in case danger may occur.

wait for a moment

Safety Considerations

Attention

Pay attention to the aeration condition to avoid anoxic symptom.

It is not allowed to put any heating apparatus under the indoor units, for the heat may cause distortion of the units.

Flammable apparatus should not be placed in the place where the air conditioner wind could reach directly, or incomplete burning of the apparatus may be caused.

Check the mount table of the air conditioner for damage for a long period of operation. If placed on the damaged table, the unit may drop down causing damage.

Plants and animals should not be put to the place where wind of the air conditioner blows directly, otherwise damage to them may be caused.

It cannot be used for the preservation of food, living creature, precise instrument and artworks, etc, otherwise damage may occur

Use the fuse with proper capacity . Metal wires and copper wires, etc., may cause fire or other faults.

Do not use water heater or like next to the indoor unit and the wired controller. Water/power leakage or short circuit may happen if the steam generating apparatus is working next to machine.

Defrosting during heating T o improve the heating effect, the outdoor unit will perform defrosting automatically when frost appears on the outdoor unit during heating (approximately 2-10 min). During defrosting, the fan of the indoor unit runs at a low speed or stops while that of the outdoor unit stops running.

Power should be cut off when the air conditioner is left unused for a long period. Power will be consumed if the air conditioner is not powered off. The power switch of the outdoor unit switch should be powered on 12 hours in advance before operation to protect the unit after a long period of storage.

3-minute protection To protect the unit, compressor can be actuated with at least 3-minute delay after stopping.

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 switch with the wet hand to avoid power shock.

Stop running and switch off the manual power switch when cleaning the unit.

During the operation of the control unit, donít switch off the manual power switch and the controller can be used. Please do not press the liquid crystal zone of controller to prevent damage

Cleaning the unit with water may cause electric shock.

Do not put flammable spray close to the air conditioner. Donít inject flammable spray towards the air conditioner, which may cause fire.

Fault Checkup

Please check the following when consigning repair service:

Symptoms

Reasons

W ater flow sound can be heard when starting operation, during operation or immediately after stopping operation. When it starts to work for 2-3 minutes, the sound may become louder, which is the flowing sound of refrigerant or the draining sound of condensed water.

During operation, the air conditioner may make the cracking sound, which is caused from the temperature changes or the slight dilation of heat exchanger.

The terrible smell, caused from walls, carpet, furniture, clothing, cigarette and cosmetics, attaches on the conditioner.

When switching it on again after power failure, turn on the manual power switch and the operating indicator flashes.

It displays the awaiting indication as it fails to perform refrigerating operation while other indoor units are in heating operation. When the operator set it to the refrigerating or heating mode and the operation is opposite to the setting, it displays the awaiting indication.

T o prevent oil and refrigerant from blocking the shutdown indoor units, refrigerant flows in the short time and make the sounds of refrigerant flowing. Otherwise, when other indoor units performs heating operation, white steam may occur; during refrigerating operation, cold air may appear.

When the conditioner is powered on, the sound is made due to the resetting of the expansion valve.

Check if it is in the state of Timer-ON and Timer-OFF. Check if there is a power failure.

Check if the manual power switch is turned off. Check if the supply fuse and breaker are disconnected. Check if the protective unit is working. Check if refrigerating and heating functions are selected simultaneously with the awaiting indication on line control.

Check if air intake port and air outlet port of outdoor units are blocked. Check if the door and windows are open. Check if the filtering screen of air cleaner is blocked with sludge or dust. Check if the setting of wind quantity is at gentle breeze or low wind. Check if the setting of operation is at the fan operation state. Check if the temperature setting is proper.

Only when the air cleaner is switched off and disconnected to the power supply can it be cleaned,

or electric shock and injury may appear.

Maintenance before and after Operating Season

Before Operating Season:

1. Please make the following checkup. If abnormal condition occurs, consult the after-service personnel.

There is no blockage in inlet port and outlet port of outdoor and indoor units. The ground line and the wiring are in the proper state

2. After cleaning, the air cleaner must be mounted.

3. Switch on to the power. After Operating Season:

1. In sunny days, blowing operation can be performed for half a day to make the inside of machine dry.

2. Electrical power should be cut down to economize electricity, or the machine will still consume power.Air cleaner and shell must be mounted after cleaning.

Cleaning Air Cleaner:

Donít rinse the air cleaner with hot water of above 50* to avoid fading and distorting. Donít put the air cleaner on the fir to dry to avoid catching fire.

Attention

Wipe dust with water or dust collector. (A) Wipe dust with dust collector.

(B) Clean it with soft bush in mild detergent if there is too much dust on it

Throw off the water and airing it in the cool dry condition.

Cleaning Wind Deflector:

Do not wipe the wind deflector with water forcibly to avoid the floss falling off.

Cleaning the air outlet port and the shell:

Donít use gasoline, benzene, diluents, polishing powder or liquid insecticide to clean them. Do not clean them with hot water of above 50* to avoid fading or distorting.

Attention

Wipe them with soft dry cloth. Water or neutral dry cleanser is recommended if the dust cannot be removed. The Wind Deflector can be dismantled to clean (as below).

Maintenance

Clean the machine (Cleaning ways are approximately same, taking AS182MCAHA indoor machine as example). Turn off the air conditioner before cleaning. Do not touch the machine if the hands are wet. Neither hot water nor solvent should be used in cleaning.

7.Close the inlet grid. Tips: The multiple photo-catalyst and the high efficiency sterilizer are efficient over a long period of time, which neednít replacing. (Ti02 nanoparticles in the multiple photo-catalyst can be activated by the UV light photo-catalyst from the UV light sterilizer, which has a long-lasting sterilizing effect. The multiple photo-catalyst doesnít need sunshine.) However, cleaning should often be done, which can be done with a dust collector or tapped gently after removal of the air cleaner, to improve the operating effect. Rinsing the multiple photo-catalyst and the high efficiency sterilizer with water is not allowed. When the high efficiency sterilizer stops operation, put it in cool dry environment. The exposure to sunlight for a long time is not allowed as to prevent reducing the sterilizing effect.

Before switching it on, test the supply terminal tier (L, N terminals) and grounding points with 500V megaohm meter and check if the resistance is above 1M*. It canít be operated if it is below 1M*. Connect it to the power supply of outdoor units to energize the heating belt of the compressor. To protect the compressor at startup, power it on 12 hours prior to the operation.

Check if the arrangements of the drainpipe and connection line are correct.

The drainpipe shall be placed at the lower part while the connection line placed at the upper part. Heat preservation measures should be taken such as winding the drainpipe esp. in the indoor units with heating insulating materials. The drain pipe should be made a slope type to avoid protruding at the upper part and concaving at the lower part on the way.
