FTXM-V Series
Precautions on Installation
• Check the strength and level of the installation surface so that the unit does not cause
any operating vibrations or noise after installation.
• Fix the unit in place securely using foundation bolts, as in the figure. (Prepare 4
sets of 5/16 inch (M8) or 3/8 inch (M10) foundation bolts, nuts and washers; all sold
separately.)
• It is best to screw in the foundation bolts until their ends are 3/4 inch (20mm) from the
foundation surface.

Refrigerant piping must be kept to a minimum.
* Be sure to add the proper amount of additional refrigerant.
Failure to do so may result in reduced performance.
** The suggested shortest pipe length is 10ft (3m), in order to avoid
noise from the outdoor unit and vibration.
(Mechanical noise and vibration may occur depending on how
the unit is installed and the environment in which it is used.)
If strong wind blows into the air
discharge side from the front and
there is a danger that the fan may be
damaged, change the orientation of
the air discharge side of the outdoor
unit or use an air direction adjustment
grille (sold separately).
In sites with poor drainage, use
block bases for the outdoor unit.
Adjust foot height until the unit is
level. Otherwise, water leakage or
pooling of water may occur.

Install a plastic cover or equivalent.
Allow space for piping
and electrical servicing.
If there is a danger of the unit falling or overturning,
fix the unit with foundation bolts, or with wire or
other means.
