Measure and mark the position for the hanging rod.
Drill the hole for the angle nut on the ceiling and fix
the hanging rod.
•
The installation template is extended according to
temperature and humidity. Check on dimensions in
use.
•
The dimensions of the installation template are the
same as those of the ceiling opening dimensions.
•
Before ceiling laminating work is completed, be
sure to fit the installation template to the indoor unit.
NOTE
Be sure to discuss the ceiling drilling work with the
installers concerned.
•
Confirm the pitch of the hanging rod.
•
Hold the unit and hang it on the hanging rod with
the nut and washer.

•
Confirm with a level gauge that the unit is installed
horizontally and tighten the nut and bolt to prevent
unit failing and vibration.
•
Open the ceiling board along the outer edge of the
paper installation template.
•
Drain pipe must be in downward gradient for
smooth drainage.
•
Avoid installing the drain pipe in up and down slope
to prevent reversed water flow.
•
During the drain pipe connection, be careful not to
exert extra force on the drain connector at indoor
unit.
•
The outside diameter of the drain connection at the
flexible drain hose is 20mm.
•
Be sure to execute heat insulation (polyethylene
foam with thickness more than 8.0mm) on the drain
piping to avoid the condensed water dripping inside
the room.
•
Connect the main drain pipe to the flexible drain.
•
Feed water from flexible drain hose to check the
