WARNING

Always have the unit installed by Authorized Mitsubishi

Representative or similar professional.

Improper installation by the user could result in problems such as

water leakage, electric shock or fire.

Always use the designated cables and connect them properly.

When connecting the terminals, make sure that external forces

from the cable is not being conveyed to the terminal and then

tighten it securely.

Improper or loose connections could cause excessive heat or fire.

Only use Mitsubishi-approved accessories, such as an air

cleaner, humidifier or electric heater.

Always have such accessories installed by an Authorized Mitsubishi

Representative or similar professional. Improper installation by the

user may result in water leakage, electric shock or fire.

Install the unit according to this Installation Manual.

If the unit is installed improperly, water leakage, electric shock or fire

may result.

Have all electric work performed by a properly licensed

electrician. Electric work should be performed in strict adherence

to procedures to this Installation Manual. Always provide a

dedicated power supply.

If the capacity of the power supply is inadequate, it could result in

problems such as electric shock or fire.

Authorized Mitsubishi Representative.

Improper repair could result in problems such as water leakage,

electric shock or fire.

CAUTION

PRECAUTIONS BEFORE INSTALLATION

Never use for special applications such as storing food, plants,

precision equipment or art.

The quality of these items may deteriorate.

Never use the unit in special environments.

Special environments with high concentrations of oil, steam or sulfuric

gases will reduce the performance of the air condition and cause its

parts to deteriorate.

Never install the unit where run-off could result in damage.

If the humidity in the room exceeds 80% or if the drain becomes

clogged, water may drain off of the indoor unit. When the unit is used

for heating, there may be drainage from the outdoor unit. If required,

provide collector drain for the outdoor unit.

Always provide adequate signal noise protection when installing

in facilities such as hospitals and communication stations.

Equipment at these facilities, such as inverters, in-house generators,

high-frequency medical equipment, two-way communication

equipment, may cause the air conditioner to operate improperly.

Conversely, the signal noise from the air conditioner may affect

the operation of medical equipment and two-way communication

equipment and this could interfere with the medical treatment being

given a patient or cause disturbances or interference in video

broadcasting equipment.

PRECAUTIONS BEFORE REMOVE AND ELECTRIC WORK

Route wiring so that there is no tension.

Tension could cause the wire to break and this could result in

excessive heat or fire.

Dispose of packing materials properly.

Use care when transporting the unit.

• Always use two or more people for lifting a product weight 20 kg or

more.

• Some products are packaged with plastic wrapping bands. Never use

these for lifting or transporting the product.

• Never touch the fins on the heat exchanger. They are sharp and

could cause cuts.

• Never allow children to play with the plastic bags used for packaging.

Always tear them up when disposing. A child could suffocate in these

bags.

PRECAUTIONS BEFORE TEST RUN

Never touch the switch with wet hands.

Electric shock could occur.

Never operate the air conditioner with the panel or guard

removed.

The hand could come in contact with rotating, hot or high-pressure

components. They could cause electrical shock or entanglement.

Never operate the air conditioner with the air filter removed.

Particles will enter into the air conditioner and cause damage.

Never turn off the power supply immediately after stopping the

unit.

Wait five minutes or more before turning off the power supply. Turning

off the power supply before that time could result in water leakage or

damage.

maintenance cover is installed.

Fig. 4-1

2. Connecting the pump wires to the control box of the indoor unit (Fig. 4-2)

(a) Insert the white connector into CN31 on the indoor P.C. board.

Since a connector has been inserted into both CNP and CN31 before

shipment, they must be removed.

(b) When wiring is complete, fasten the remaining cords with the band 3.

Fig. 4-2

When fastening lead wires

Power wires and low-voltage wires are separated inside the control box to prevent noise. Lead wires from the Drain Water Lift-

Up Kit also need to be separated, so fasten them to the lead wires located inside the control box as described below.

• Since the yellow wire is used for power, its remaining portion must be fastened to the lead wires from the power terminal block.

• Since the clear wire is used for low voltage, its remaining portion must be fastened to the pipe sensor lead wire.

5. Drain piping work

(1) Ensure that the drain piping is downward (pitch of more than 1/100) to

the outdoor (discharge) side. Do not provide any trap or irregularity on

the way. (Fig. 5-1)

(2) Ensure that any cross-wise drain piping is less than 20 meters

(excluding the difference of elevation). If the drain piping is long,

provide support bracket to prevent it from waving. Never provide any

air vent pipe. Otherwise drain may be ejected.

(3) Use a hard vinyl chloride pipe ø32 mm (1-1/4 inch) for drain piping.

(4) Ensure that collected pipes are 10 cm lower than the unit body’s drain

port. (Fig. 5-2)

(5) Do not provide any odor trap at the drain discharge port.

(6) Put the end of the drain piping in a position where no odor is

generated.

(7) Do not insert the end of the drain piping into any sewer where sulfuric

gases are generated.

(8) The intake of the drain piping can be made 55 cm higher than the

Indoor unit. If there are some obstacles under the ceiling, use elbows

to make it at least height according to the site. (Fig. 5-3)

(9) Be sure to use the supplied drain hose (Accessory).

Connect each connection with vinyl chloride adhesive. But never use

any adhesive over the indoor unit discharge port. Otherwise the Drain

Water Lift-Up Kit cannot be serviced later. Also, the end connection

may be eroded by resin and so cracked.

Note:

If the rise portion is long, there will be a lot of returned water in

an operation stop, generating slime or odor during off-season.

Ensure that the rise portion is at a minimum.

CAUTION

Pipe the drain piping to ensure that it discharges drain, and

insulate it to prevent dew condensation. A failure to the piping

work may cause water leakage and so wet your property.

connections.

• Be sure to confirm the above in a period of heating operation.

• Be sure to confirm the above before ceiling work is done in the case of a new construction.

(1) Turn on the SWE on the control board.

(2) Pour water into the drain pan using a kettle etc.

When pouring, make sure that the spout of the kettle is placed into the

drain pan to prevent water overflowing from the drain pan.

(Fig. 6-1)

(3) Turn on the main power of the indoor unit.

The drain pump will be forced to operate even if no remote controller

operation is performed.

Check the transparent drain socket to make sure that drain is

discharged.

(4) When it is confirmed that drain is discharged properly, turn off the main

power, and turn off the SWE on the control board.

* If the SWE remains turned on, the drain pump will be caused to

operate all the time, so make sure that it is turned off.

* The SWE must not be kept on for longer than 4 hours.

Check that all the wiring work has been completed. If so, reassemble the

covers in reverse order.
