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 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.
Adjust the unit height to 35.0 mm 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
falling 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 20 mm.
Be sure to execute heat insulation (polyethylene foam with
thickness more than 8.0 mm) on the drain piping to avoid
the condensed water dripping inside the room.
