1. Safety precautions

s Before installing the unit, make sure you read all the Safety precautions. s Please report to your supply authority or obtain their consent before connecting this equipment to the power supply system. Warning: Describes precautions that must be observed to prevent danger of injury or death to the user. Caution: Describes precautions that must be observed to prevent damage to the unit. Warning: Ask a dealer or an authorized technician to install the unit. For installation work, follow the instructions in the Installation Manual and use tools and pipe components specifically made for use with refrigerant specified in the outdoor unit installation manual. The unit must be installed according to the instructions in order to minimize the risk of damage from earthquakes, typhoons, or strong winds. An incorrectly installed unit may fall down and cause damage or injuries. The unit must be securely installed on a structure that can sustain its weight. If the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration in the room from exceeding the safety limit in the event of refrigerant leakage. Should the refrigerant leak and cause the concentration limit to be exceeded, hazards due to lack of oxygen in the room may result. After installation work has been completed, explain the Safety precautions, use, and maintenance of the unit to the customer according to the information in the Operation Manual and perform the test run to ensure normal operation. Both the Installation Manual and Operation Manual must be given to the user for keeping. These manuals must be passed on to subsequent users. : Indicates a part which must be grounded. Warning: Carefully read the labels affixed to the main unit.
Ventilate the room if refrigerant leaks during operation. If refrigerant comes into contact with a flame, poisonous gases will be released. All electric work must be performed by a qualified technician according to local regulations and the instructions given in this manual. Use only specified cables for wiring. The terminal block cover panel of the unit must be firmly attached. Use only accessories authorized by Mitsubishi Electric and ask a dealer or an authorized technician to install them. The user should never attempt to repair the unit or transfer it to another location. After installation has been completed, check for refrigerant leaks. If refrigerant leaks into the room and comes into contact with the flame of a heater or portable cooking range, poisonous gases will be released.
1.1. Before installation (Environment)
Caution: Do not use the unit in an unusual environment. If the air conditioner is installed in areas exposed to steam, volatile oil (including machine oil), or sulfuric gas, areas exposed to high salt content such as the seaside, the performance can be significantly reduced and the internal parts can be damaged. Do not install the unit where combustible gases may leak, be produced, flow, or accumulate. If combustible gas accumulates around the unit, fire or explosion may result. Do not keep food, plants, caged pets, artwork, or precision instruments in the direct airflow of the indoor unit or too close to the unit as these items can be damaged by temperature changes or dripping water. When the room humidity exceeds 80% or when the drainpipe is clogged, water may drip from the indoor unit. Do not install the indoor unit where such dripping can cause damage. When installing the unit in a hospital or communications office, be prepared for noise and electronic interference. Inverters, home appliances, high-frequency medical equipment, and radio communications equipment can cause the air conditioner to malfunction or breakdown. The air conditioner may also affect medical equipment, disturbing medical care, and communications equipment, harming the screen display quality.

1.2. Before installation or relocation
Caution: Be extremely careful when transporting the units. Two or more persons are needed to handle the unit as it weighs 20 kg, 44 lbs or more. Do not grasp the packaging bands. Wear protective gloves as you can injure your hands on the fins or other parts. Be sure to safely dispose of the packaging materials. Packaging materials, such as nails and other metal or wooden parts may cause stabs or other injuries. Thermal insulation of the refrigerant pipe is necessary to prevent condensation. If the refrigerant pipe is not properly insulated, condensation will be formed. Place thermal insulation on the pipes to prevent condensation. If the drainpipe is installed incorrectly, water leakage and damage to the ceiling, floor, furniture, or other possessions may result. Do not clean the air conditioner unit with water. Electric shock may result. Tighten all flare nuts to specification using a torque wrench. If tightened too much, the flare nut can break after an extended period.
1.3. Before electric work
Caution: Be sure to install circuit breakers. If not installed, electric shock may result. For the power lines, use standard cables of sufficient capacity. Otherwise, a short circuit, overheating, or fire may result. When installing the power lines, do not apply tension to the cables. Be sure to ground the unit. If the unit is not properly grounded, electric shock may result. Use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and molded case circuit breaker) with the specified capacity. If the circuit breaker capacity is larger than the specified capacity, breakdown or fire may result.
1.4. Before starting the test run
Caution: Turn on the main power switch more than 12 hours before starting operation. Starting operation just after turning on the power switch can severely damage the internal parts. Before starting operation, check that all panels, guards and other protective parts are correctly installed. Rotating, hot, or high voltage parts can cause injuries. Do not operate the air conditioner without the air filter set in place. If the air filter is not installed, dust may accumulate and breakdown may result. Do not touch any switch with wet hands. Electric shock may result. Do not touch the refrigerant pipes with bare hands during operation. After stopping operation, be sure to wait at least five minutes before turning off the main power switch. Otherwise, water leakage or breakdown may result.

4. Installing the refrigerant piping

4.1. Precautions

4.1.1. For devices that use R410A refrigerant
Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration oil applied to the flared sections. Use C1220 copper phosphorus, for copper and copper alloy seamless pipes, to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses specified in the table to the below. Make sure the insides of the pipes are clean and do not contain any harmful contaminants such as sulfuric compounds, oxidants, debris, or dust. Warning: When installing or moving the air conditioner, use only the specified refrigerant (R410A) to charge the refrigerant lines. Do not mix it with any other refrigerant and do not allow air to remain in the lines. Air enclosed in the lines can cause pressure peaks resulting in a rupture and other hazards. Liquid pipe Gas pipe A12, A18 6.35mm, 1/4 inch thickness 0.8 mm, 1/32 inch 12.7mm, 1/2 inch thickness 0.8 mm, 1/32 inch
