• 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 covmpleted, be sure
to fit the installation template to the indoor unit.
NOTE
Be sure to discuss the ceiling drilling work with the
installers concerned.

• Hold the unit and hang it on the hanging rod with the
nut and washer.
• Adjust the unit height to 35.0mm between the indoor
unit bottom surface and the ceiling surface.
• 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 piping
for leakage.
