► Before installing the unit, make sure you read all the “Safety

precautions”.

►

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.

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.

Contents

Warning:

• Ask the dealer or an authorized technician to install the air conditioner.

• Install the unit at a place that can withstand its weight.

• Use only specified cables for wiring. The wiring connections must be

made securely with no tension applied on the terminal connections. Also,

never splice the cables for wiring (unless otherwise indicated in this

document).
Failure

to observe these instructions may result in overheating or a fire.

• Use only accessories authorized by Mitsubishi Electric and ask the dealer

or an authorized technician to install them.

• Do not touch the heat exchanger fins.

• Install the air conditioner according to this Installation Manual.

• Have all electric work done by a licensed electrician according to local

regulations.

• If the air conditioner is installed in a small room, measures must be taken

to prevent the refrigerant concentration from exceeding the safety limit

even if the refrigerant should leak.

• The cut face punched parts may cause injury by cut, etc. The installers are
requested to wear protective equipement such as gloves, etc.

• When installing or relocating, or servicing 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.

If air is mixed with the refrigerant, then it can be the cause of abnormal

high pressure in the refrigerant line, and may result in an explosion and
other hazards.

The use of any refrigerant other than that specified for the system will

cause mechanical failure or system malfunction or unit breakdown. In the
worst case, this could lead to a serious impediment to securing product
safety.

oil to coat flares and flange connections, when use R410A or R407C
refrigerant.

• Do

not use the air conditioner where food, pets, plants, precision

instruments, or artwork are kept.

• Do not use the air conditioner in special environments.

• Ground the unit.

3.2. Installing the wall mounting fixture

3.2.1. Setting the wall mounting fixture and piping positions

► Using the wall mounting fixture, determine the unit’s installation position

and the locations of the piping holes to be drilled.

Warning:

Before drilling a hole in the wall, you must consult the building contractor.

 PKFY-P·VHM-E (Fig. 3-2)

3.2.2. Drilling the piping hole (Fig. 3-3)

► Use a core drill to make a hole of 75-80 mm diameter in the wall in the

piping direction, at the position shown in the diagram to the left.

► The hole should incline so that the outside opening is lower than the

inside

opening.

► Insert a sleeve (with a 75 mm diameter and purchased locally) through the

hole.

Note:
The

purpose

of the hole’s inclination is to promote drain flow.

3.2.3. Installing the wall mounting fixture

► Since the indoor unit weighs near 13 kg, selection of the mounting

location requires thorough consideration. If the wall does not seem to be
strong enough, reinforce it with boards or beams before installation.

► The mounting fixture must be secured at both ends and at the centre, if

possible.

Never fix it at a single spot or in any nonsymetrical way.

(If possible, secure the fixture at all the positions marked with a bold

arrow.)
Warning:

If possible, secure the fixture at all positions indicated with a bold arrow.

Caution:

• The unit body must be mounted horizontally.

• Fasten at the holes marked with

▲ as

shown by the arrows.

3.3. When embedding pipes into the wall (Fig. 3-5)

• The pipes are on the bottom left.

• When the cooling pipe, drain pipes internal/external connection lines etc are to
be embedded into the wall in advance, the extruding pipes etc, may have to be
bent and have their length modified to suit the unit.

• Use marking on the mount board as a reference when adjusting the length of the
embedded cooling pipe.

• During construction, give the length of the extruding pipes etc some leeway

.

BReference marking for flare connection
CThrough hole
DOn-site piping

3.4. Preparing the indoor unit

* Check beforehand because the preparatory work will differ depending on the

exiting direction of the piping.

* When bending the piping, bend gradually while maintaining the base of the

piping exiting portion. (Abrupt bending will cause misshaping of the piping.)

Extraction and processing of the piping and wiring (Fig. 3-6)

1. Connection of indoor/outdoor wiring ➡ See page. 8.

2. Wrap the felt tape 3 in the range of the refrigerant piping and drain hose which

will be housed within the piping space of the indoor unit.

•

Wrap the felt tape

3 securely from the base for each of the refrigerant piping

and the drain hose.

•

Overlap the felt tape 3 at one-half of the tape width.

• Fasten the end portion of the wrapping with vinyl tape.

ALiquid pipe
BGas pipe
CIndoor/outdoor connection cable
DDrain hose
EFelt tape 3

3. Be careful that the drain hose is not raised, and that contact is not made with the

indoor unit box body.
Do not pull the drain hose forcefully because it might come out.

Rear, right and lower piping (Fig. 3-7)

1) Be careful that the drain hose is not raised, and that contact is not made with
the indoor unit box body.
Arrange the drain hose at the underside of the piping and wrap it with felt
tape 3.

2)

Securely wrap the felt tape 3 starting from the base. (Overlap the felt tape at

one-half of the tape width.)
