WARNING
Do not touch the fins. Otherwise, personal injury could result.
CAUTION
When carrying the unit, hold the handles on the right and left sides and be careful. If
the outdoor unit is carried from the bottom, hands or fingers may be pinched.
• Be sure to hold the handles on the sides of the unit. Otherwise, holding the suction
grille on the sides of the unit may cause deformation.

3. 5. Installation of the unit
• Install 4 anchor bolts at the locations indicated with arrows in the figure.
•
To reduce vibration, do not install the unit directly on the ground. Install it on a secure
base (such as concrete blocks).
• The foundation shall support the legs of the unit and have a width of 1 in. (50 mm) or
more.
• Depending on the installation conditions, the outdoor unit may spread its vibration
during operation, which may cause noise and vibration. Therefore, attach damping
materials (such as damping pads) to the outdoor unit during installation.
• Install the foundation, making sure that there is enough space for installing the
connection pipes.
• Secure the unit to a solid block using foundation bolts. (Use 4 sets of commercially
available M10 bolts, nuts, and washers.)
• The bolts should protrude 1 in. (20 mm) (Refer to the figure.)
•
If overturning prevention is required, purchase the necessary commercially available
items.

• Do not install directly on the ground, this
may result in equipment failure.
2” (5 cm) or over
CAUTION
In areas with heavy snowfall , where intake and outlet of the outdoor unit can become
blocked by snow. It is recommended that unit be installed under a canopy or elevated
on a high stand.
Failure to do so will result in poor heating performance and/or premature failure of
equipment.
In places where the outdoor temperature drops to 32 °F (0 °C) or lower, the drain
water may freeze and may stop up the drain or cause other outdoor unit trouble.
Therefore take measures so that the drain water will not freeze and clog the drain.
Please set up the outdoor unit in a high place and please do not arrange the frame of
installed stand under the drain port, because the water dropped from the drain port
repeats freezing and accumulating, and may block the drain port.
