PRECAUTIONS BEFORE TEST RUN
PRECAUTIONS BEFORE REMOVE AND ELECTRIC WORK
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.
Install the unit according to this Installation Manual.
If the unit is installed improperly, water leakage, electric shock or fire
may result.
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 clean-
er, 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.
Have all electric work performed by a properly licensed electri-
cian. Electric work should be performed in strict adherence to
procedures to this Installation Manual. Always provide a dedicat-
ed power supply.
If the capacity of the power supply is inadequate, it could result in prob-
lems such electric shock or fire.
Never modify the unit and always have repairs performed by an
Authorized Mitsubishi Representative.
Improper repair could result in problems such water leakage, electric
shock or fire.

.WARNING
.CAUTION
Never use for special applications such as storing food, plants,
precision equipment or art.
The quality of these items may deteriorate.
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 equip-
ment, 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.
Never operate the air conditioner with the air filter removed.
Particles will enter into the air conditioner and cause damage.
Route wiring so that there is no tension.
Tension could cause the wire to break and this could result in exces-
sive heat or fire.
Dispose of packing materials properly.
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 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.
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.
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. Achild could suffocate in these
bags.
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.

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 m
(excluding the difference of elevation). If the drain piping is long,
provide metal braces to prevent it from waving. Never provide
any air vent pipe. Otherwise drain may be ejected.
3. Use a hard vinyl chloride pipe VP-25 (with an external diameter
of 32 mm) 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 put the end of the drain piping in any drain where ionic
gases are generated.
8. The intake of the drain piping can be made 41 cm higher than
the drain discharge port. If there are some obstacles under the
ceiling, use elbows to make it at least height according to the
site. (Fig. 5-3)

Connect each connection with vinyl chloride adhesive. But never
use any adhesive over the indoor unit discharge port. Otherwise
the drain-up mechanism cannot be serviced later. Also, the end
connection may be eroded by resin and so cracked.
Fig. 5-3
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-sea-
son. Ensure that the rise portion is at a minimum.
Pipe the drain piping to ensure that it discharges drain, and
insulate it to prevent dew condensation. A failure to the pip-
ing work may cause water leakage and so wet your property.
6 Confirming drain discharge
1. Insert the enclosed connector➆into the red connector (2P) on the side of the
control box.
2. Remove the polyethylene plugBon the same side as the indoor unit piping.
3. Fill water into the feed water pumpAusing a feed water tank. In filling, be
sure to put the end of the pump in drain pan. (If the insertion is incomplete,
water may flow over the machine.)
4. Turn on the main power. The drain pump is forced to operate without any
remote controller operation. Make sure using a transparent drain hose(acces-
sory) that drain is discharged.
5. After confirmation, turn off the main power, remove the connector, and insert
the polyethylene plug into its original position, insulate drain hose.
AInsert the pump’s end 2 to 4 cm.
BRemove the polyethylene plug.
CAbout 1000 ml
DWater
EFilling port
Caution:
Make sure that the drain-up mechanism operates normally for discharge
and that there is no water leakage from the 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.
