• Measure and mark the position for the hanging rod.
Drill the hole for the angle nut on the ceiling and fix
the hanging rod.

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

• Hold the unit and hang it on the hanging rod with the
nut and washer.
• Adjust the unit height to 35mm 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 8mm) 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.
• When the test is completed, connect the flexible drain
