Installation Manual
This installation manual contains only the description of how to install the Drain water Lift-Up Kit PAC-KE04DM-F. For information about how to
wire and how to install air conditioning units, see the installation manual for them.
For your safety, first be sure to read “ 1 Safety Precautions “ described below thoroughly and then install the Drain water Lift-Up Kit PACKE04DM-F correctly.
1 Safety Precautions
● The following two symbols are used to denote dangers that may be caused by incorrect use and their degree:
. WARNING
. CAUTION
This symbol denotes what could lead to serious injury or death if your misuse the PAC-KE04DM-F.
This symbol denotes what could lead to a personal injury or damage to your property if you misuse the PAC-KE04DM-F.
● After reading this installation manual, keep it in a place where the final user can see it anytime he or she wants to it.
When someone moves, repairs or uses the PAC-KE04DM-F, make sure that this manual is forwarded to the final user.
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 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.
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.
PRECAUTIONS BEFORE TEST RUN
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.
Never touch the switch with wet hands.
Electric shock could occur.
Never operate the air conditioner with the air filter removed.
Particles will enter into the air conditioner and cause damage.
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 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.

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 2-wire cord (with a blue and a red connector) is used for power, its remaining portion must be fastened to the
power transformer’s primary side (white lead wire) and the lead wires from the power terminal block.
• Since the 2-wire cord (with a white a connector) is used for low voltage, its remaining portion must be fastened to the pipe
sensor lead wire.

5 Drain piping work (common to the all models)
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)
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.

6. Put the end of the drain piping in a position where no odor is
generated.
Fig. 5-3
7. Do not insert the end of the drain piping into any sewer where
sulfuric gases are generated.

Less than 300 mm
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.

Less than 550 mm
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.

6 Confirming drain discharge (common to the all models)
▲
Make sure that the Drain Water Lift-Up Kit 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.
1. Insert the connector ➃ into the test run connector (red) of the 2-wire
cord of the drain pump.

2. Remove the heat exchanger cover from the indoor unit.
(refer to 3-1 (2):Model P40 to P140VMH, P15 to P54NMHU)
(refer to 3-4 (2):Model P200 / P250VMH, P72 / P96NMHU)
3. 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.
(Photos 6-1, 6-2)
4. 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 hose to make sure that drain is discharged.
5. When it is confirmed that drain is discharged properly, turn off the
main power, remove the connector ➃ and insert the dummy connector ➄.
❇ If the connector ➃ remains inserted, the drain pump will be
caused to operate all the time, so make sure that it is removed
and dummy connector ➄ is inserted instead.
