2. About the product
Warning:
• Do not use refrigerant other than the type indicated in the manuals provided
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 mal-
functions 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 con-
ventional refrigerant because the design pressure in systems using R410A is
higher. Refer to 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 Data
Book for more information.
• Do not use the existing piping, as it contains chlorine, which is found in conven-
tional 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.

6. Installation of unit and service space
6.1. Installation
• Using the anchoring holes shown below, firmly bolt the unit to the base.
[Fig. 6.1.1] (P.2)
Bases
• Be sure to install unit in a place strong enough to withstand its weight. If the base
is unstable, reinforce with a concrete base.
• The unit must be anchored on a level surface. Use a level to check after installa-
tion.
• If the unit is installed near a room where noise is a problem, using an anti-vibration
stand on the base of the unit is recommended.
Warning:
• Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a personal
injury.
• Have installation work in order to protect against earthquake.
Any installation deficiency may cause unit to fall down, resulting in a per-
sonal injury.
6.2. Service space
• Please allow for the following service spaces after installation.
(All servicing can be performed from the front of the unit)
