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

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.

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 dedi-

cated power supply.

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

problems 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 sta-

tions.

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 equip-

ment 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 sulfu-

ric 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 packag-

ing. Always tear them up when disposing. A child 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.

•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.

•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.

•Use a hard vinyl chloride pipe O.D. ø32 for drain piping.

•Ensure that collected pipes are 10 cm lower than the unit body's drain port.

•Do not provide any odor trap at the drain discharge port.

•Put the end of the drain piping in a position where no odor is generated.

•Do not put the end of the drain piping in any drain where ionic gases are generated.

Water

Do not splash water on the drain pump coil or the

float switch wire through hole when pouring water.

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.

•Make sure that water is not leaking from the connection (e) on

the drain pump shown in the right figure.

5 Confirming drain discharge

5-1. Fill water into the feed water pump using a feed water tank. In filling, be sure to put the end of the pump or

tank in a drain pan. (If the insertion is incomplete, water may flow over the machine.)

✻ Do not splash water on the drain pump coil or the float switch wire through hole when pouring water.

5-2. Perform the test run in cooling mode, or turn on the switch SWE on the controller circuit board. (The drain

pump and the fan are forced to operate without any remote controller operation.) Make sure using a transpar-

ent hose that drain is discharged.

5-3. After confirmation, cancel the test run mode, and turn off the main power. When the switch SWE has been

turned on, turn it off, and attach the CONTROL BOX COVER and the DRAIN PUMP COVER in the original

positions.
