(3) Installation
Securely fix the outdoor unit on the foundation to prevent collapse in a strong wind or an earthquake or noise due to loss of
level (leaning aside).
1) Secure the unit on the foundation with anchor bolts.
2) Anchor bolt size.
3) Verify drainage and drain pipe installation.
● Water will drain from the unit when it rains. Install the
unit at locations with good drainage and drain water to
the ditch. Also, avoid install the unit overhead as water
will drip from the unit. Plan drainage for the secondary
condensate tray if overhead installation is necessary.

anchor bolts. Otherwise, it will be difficult to remove the
pipe cover.
5) Securely fix the outdoor unit on the foundation to prevent

loss of level (leaning aside).
6) When using ordinary frames whose legs are narrower than
the legs of the outdoor unit, add a board under the legs of
the outdoor unit as shown in the figure before installation
to ensure all legs of the outdoor unit are adequately
supported on the frame.
