Safety Precautions

• Read these Safety Precautions and perform installation work accordingly.
• The following two symbols include important notes concerning safety, so be
sure to read and follow them.
Warning:
This symbol denotes what could lead to serious injury or death if you
misuse the CMP-P·LW-D / CMP-P·LX-D / CMP-VLW-B.
Caution:
This symbol denotes what could lead to a personal injury or damage to
your property if you misuse the CMP-P·LW-D / CMP-P·LX-D / CMP-VLW-B.
• After reading this installation manual, give it and the instruction manual to the
end user.
• The end user should keep this manual and the indoor unit installation manual
in a place where he or she can see it at anytime. When someone moves or
repairs the CMP-P·LW-D / CMP-P·LX-D / CMP-VLW-B, make sure that this
manual is forwarded to the end user.
Warning:
• Ask your dealer or technical representative to install the unit.
- Any deficiency caused by your own installation may result in an electric
shock or fire.
• Firmly connect the wiring using the specified cables. Carefully check
that the cables do not exert any force on the terminals.
- Improper wiring connections may produce heat and possibly a fire.
• Be sure to select Mitsubishi-designated products when purchasing
separately retailed products such as a humidifier.
- Also, be sure to request the services of a specialist technician for
installation work, as installation by an untrained person (user, etc.) may
result in deficiencies such as leaks, electric shock or fire.
• Ensure that installation work is performed correctly in adherence to this
installation manual.
- Any deficiency caused by installation may result in leaks, electric shock or
fire.
• All electrical work must be performed by a licensed technician in
accordance to technical standards related to electrical facilities,
extension bylaws and the instructions given in this manual. And always
use a dedicated power supply.
- Insufficient electrical circuit capacity and/or installation deficiencies may
cause electric shock or fire.
• Never alter the installation setup. Talk to your retailer if repairs are
required.
- Repair deficiencies may cause leaks, electric shock or fire.
Prior to installation
Caution:
• Do not use this system for special applications such as the storage of
food, flora & fauna, precision instruments and works of art.
- Doing so may cause the quality of the item concerned to deteriorate.
• When installing this system in a hospital or communication facility, take
ample countermeasures against noise.
- Inverters, household generators and high-frequency communication
equipment may cause the air conditioner to malfunction or fail. Moreover,
the air conditioner may effect medical equipment or communication
equipment preventing patient therapy or interfering with image
transmissions or causing noise.
• Do not use in any special environment.
- Using in any place exposed to oil, steam and sulfuric gas may deteriorate
the performance significantly or give damage to the component parts.
• Do not install unit above items that if leaked upon would cause
problems.
- Moisture drips from the indoor unit if humidity exceeds 80% or the drain
outlet becomes blocked. Also, when the unit is used as a heater, the
outdoor unit's drain will drip, so, if necessary, also provide a confluent drain
for the outdoor unit.
Prior to Installation (Various Units) and Electrical Wiring
Caution:
• Wire the units so that there is no tension on the electrical wiring.
- Tension may cause wire breakage, heating or fire.
• Be sure to comprehensively dispose of packing material.
• Be sure to take ample precautions for transportation of the product.
- Products weighing 20 kg or more should not be transported by one person.
- Some products come packaged with polypropylene bands. Do not use such
bands when transporting the product, as doing so may cause accidents.
- The front side of the heat exchanger fan may cause cuts if touched with a
bare hand, so wear gloves and take care when handling.
- Plastic bags must be kept away from children. Also be sure to tear them
before throwing away to further reduce the risk of suffocation accidents.

Prior to Trial Operation
Caution:
• Do not touch switches with wet hands.
- Doing so may cause an electric shock.
• Do not run the system with the air filter removed.
- Doing so may cause the system to fail due to internal dirt blockages.
• Do not run the system with the panel and/or guard removed.
- Doing so may cause burn and/or electric shock injury due to contact with or
enmeshing in the machine, moving parts, high-temperature units and/or
highvoltage units.
• Do not turn OFF the power immediately after halting operation.
- Always wait at least five or more minutes before turning OFF the power to
prevent leaks and system failure.

3. Preparation Prior to Installation of
Decorative Panel
Check to see that the unit body has been suspended correctly prior to
installation of the decorative panel. For the unit body to be correctly installed, its
bottom surface must be raised above the ceiling surface at a height between
57 mm and 67 mm (see Diagram 2). Use the panel gauge at the top of the
cardboard box to adjust and check the main unit's installation position from the
short and long sides of the rectangular opening as shown in the following figure.
[Diagram 2] (P.2)
A Spirit level
B Ceiling opening dimension in the short side direction
C Main unit
D Check to see that the main unit is level using a spirit level.
E Ceiling opening dimension in the long side direction
F Panel gauge
G Install panel gauges in the directions suitable for the short side direction and the
long side direction as shown in the diagram.
H Ceiling opening ends
I Set the ceiling opening ends to this range. (Recomended 10 mm)
• Insufficient air flow, moisture dripping and panel warping may occur if the
unitbody is incorrectly aligned with the ceiling surface.
(The panel gauge is designed to show the standard installation positions.)
• Check to see that the ceiling opening has the following dimensions.
Model 40 dimensions: 1040 × 670
Model 63 dimensions: 1210 × 670
Model 100 dimensions: 1710 × 670
Model 125 dimensions: 1970 × 670
• Move the service panel in the order shown in Diagram 3 to remove it.
(Cushioning material is sandwiched between the panel frame and the panel.
Take out this cushioning and then remove the panel.)
