Install The Indoor Unit On A Ceiling Strong Enough To Sustain Its Weight; Securing Installation And Service Space; Combing Indoor Units With Outdoor Units; Fixing Hanging Bolts - Mitsubishi Electric Mr.Slim PEA-RP200WKA Mode D'emploi

• Do not install unit at a site where combustible gas may generate, flow in, stagnate
or leak.
• Do not install unit at a site where equipment generating high frequency waves (a
high frequency wave welder for example) is provided.
• Do not install unit at a site where fire detector is located at the supply air side. (Fire
detector may operate erroneously due to the heated air supplied during heating
operation.)
• When special chemical product may scatter around such as site chemical plants
and hospitals, full investigation is required before installing unit. (The plastic com-
ponents may be damaged depending on the chemical product applied.)
• If the unit is run for long hours when the air above the ceiling is at high tempera-
ture/high humidity (due point above 26 °C), due condensation may be produced in
the indoor unit. When operating the units in this condition, add insulation material
(10-20 mm) to the entire surface of the indoor unit to avoid due condensation.
3.1. Install the indoor unit on a ceiling strong
enough to sustain its weight
Warning:
The unit must be securely installed on a structure that can sustain its weight. If
the unit is mounted on an unstable structure, it may fall down causing injuries.

5. Installing the unit

5.1. Hanging the unit body

 Bring the indoor unit to an installation site as it is packed.
 To hang the indoor unit, use a lifting machine to lift and pass
through the hanging bolts.

5.2. Transporting the heat exchanger unit
and the fan unit separately
 Refer to the "Manipulation Details" label on the unit for how to
separate the heat exchanger unit and the fan unit.
Caution:
Heat exchanger unit and the fan unit cannot be installed in separate locations.
Doing so will cause water leakage.

6. Refrigerant pipe and drain pipe specifications

To avoid dew drops, provide sufficient antisweating and insulating work to the refrig-
erant and drain pipes.
When using commercially available refrigerant pipes, be sure to wind commercially
available insulating material (with a heat-resisting temperature of more than 100 °C
and thickness given below) onto both liquid and gas pipes.
Be also sure to wind commercially available insulating material (with a form polyeth-
ylene's specific gravity of 0.03 and thickness given below) onto all pipes which pass
through rooms.
1 Select the thickness of insulating material by pipe size.
Pipe size
6.4 mm to 25.4 mm
28.6 mm to 38.1 mm
2 If the unit is used on the highest story of a building and under conditions of high
temperature and humidity, it is necessary to use pipe size and insulating mate-
rial's thickness more than those given in the table above.
3 If there are customer's specifications, simply follow them.
W (mm) L (mm)
1034 1324
Insulating material's thickness
More than 10 mm
More than 15 mm

3.2. Securing installation and service space

• Select the optimum direction of supply airflow according to the configuration of the
room and the installation position.
• As the piping and wiring are connected at the bottom and side surfaces, and the
maintenance is made at the same surfaces, allow a proper space properly. For the
efficient suspension work and safety, provide a space as much as possible.

3.3. Combing indoor units with outdoor units

For combining indoor units with outdoor units, refer to the outdoor unit installation
manual.
Hanging structure
• Ceiling: The ceiling structure varies from building to one another. For detailed
information, consult your construction company.
• If necessary, reinforce the hanging bolts with anti-quake supporting members as
countermeasures against earthquakes.
* Use M10 for hanging bolts and anti-quake supporting members (field supply).

5.3. Confirming the unit's position and fixing
hanging bolts
 Ensure that the hanging bolt nuts are tightened to fix the hanging
bolts.
 To ensure that drain is discharged, be sure to hang the unit at
level using a level.
Caution:
Install the unit in horizontal position. If the side with drain port is installed
higher, water leakage may be caused.
