2. Selecting an installation site
2.1. About the product
Warning:
• Do not use refrigerant other than the type indicated in the manuals pro-
vided with the unit and on the nameplate.
- Doing so may cause the unit or pipes to burst, or result in explosion or fire
during use, during repair, or at the time of disposal of the unit.
- It may also be in violation of applicable laws.
- MITSUBISHI ELECTRIC CORPORATION cannot be held responsible for
malfunctions or accidents resulting from the use of the wrong type of
refrigerant.
• This unit uses R410A-type refrigerant.
• Piping for systems using R410A may be different from that for systems using
conventional refrigerant because the design pressure in systems using
R410A is higher. Refer to the Data Book for more information.
• Some of the tools and equipment used for installation with systems that use
other types of refrigerant cannot be used with the systems using R410A.
Refer to the Data Book for more information.
• Do not use the existing piping, as it contains chlorine, which is found in
conventional refrigerating machine oil and refrigerant. This chlorine will
deteriorate the refrigerant machine oil in the new equipment. The existing
piping must not be used as the design pressure in systems using R410A is
higher than that in the systems using other types of refrigerant and the
existing pipes may burst.
2.2. Installation site
• Install the unit in a place not exposed to rain. The BC controller is designed to
be installed indoors.
• Install the unit with adequate space around it for servicing.
• Do not install the unit in a place that would result in the piping length
restrictions being exceeded.
• Install the unit in a place not exposed to direct radiant heat from other heat
sources.
• Do not install the unit in any oily steamy place or near any machine that
generates high frequencies. Doing so may cause a risk of fire, erroneous
operation or dew drop.
• Allow enough space and access to ensure water piping, refrigerant piping
and electrical wiring can be easily connected.
• Avoid places exposed to the generation, inflow, accumulation or leakage of
flammable and sulfuric gases.
• Ensure a downward gradient of at least 1/100 for drain piping.
• Properly install the unit on a stable, load-bearing surface.
• Do not install the unit in a place subject to a large amount of steam. Using the
unit in a humid environment may cause condensation during a cooling
operation.
• If the inside of the ceiling on which the unit is installed becomes hot and
humid, operating the unit for a long time in such environment may cause
condensation. However, it poses no problem because condensation water will
flow into a drain pan. Though an area where condensation occurred may be
colored in white, it does not affect normal operation of the unit.
• Make sure that condensation water of the unit does not come into contact
with surrounding wirings.
1. For hanging from the ceiling [Fig. 2.2.1] (P.2)
• Provide an inspection hole 450 mm square in the ceiling surface as shown in
[Fig. 2.3.1] (P.2).
• Install the unit in a suitable location (such as in the ceiling of a corridor or in
the bathroom etc) away from places regularly occupied. Avoid installing in the
center of a room.
• Ensure a pull out strength of at least 60 kg per bolt for hanging bolts.
• Be sure to install the BC controller horizontally.
• Install the unit in a location where the noise from the BC controller will not
directly be heard.
• Install the unit in a location where the noise from the unit will not be a
problem. (Install indoor unit and BC controller at least 5 m away from each
other when installed in a space with low background noise, e.g., hotel rooms).
Sound pressure level is as follows.

*1. The sound pressure level values were obtained in an anechoic room.
Actual sound pressure level is usually greater than that measured in an
anechoic room due to the ambient noise and deflection sound.
*2. The sound pressure level values were obtained at the location below
1.5 m from the unit.
*3. The solenoid valve switching sound is 56 dB regardless of the unit model.
Warning:
Be sure to install the unit in a place that can sustain the entire weight.
If there is a lack of strength, it may cause the unit to fall down, resulting in
an injury.
Caution:
Be sure to install the unit horizontally.
