• 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 tempera-
ture 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
installers concerned.
3. Unit Hanging

• Hold the unit and hang it on the hanging rod with the nut and
washer.
• Adjust the unit height to 30.0mm 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

4. Drain Pump Work
Indoor Unit
Pipe Clamp
Good
• 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.
5. Drain Test
Feed Water
Flexible Drain Hose
• 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 hose
to the drain connector on the indoor unit.
Note: This indoor unit uses a drain pump for condensed
water drainage. Install the unit horizontally to
prevent water leakage or condensation around the air
outlet.
• Open the air intake grille by pulling back the catchers
and removing it together with filter from panel.
• Install the front frame panel onto the indoor unit by
4 screws and tighten it completely to prevent cool air
leakage.
• Connect the LED wire and air swing wire to the indoor
unit.
Note: Install the front frame panel firmly to prevent cool
air leakage which will cause condensation and
water dripping.
