•	Apply thermal insulation the drain hose with the attached thermal
	insulation pipe.
	Set the both ends of the drain hose closely to the drain pan.
•	If a gap is generated on the matched section of the thermal insulation
	materials at the both ends, seal the section by winding the thermal
	insulation tape.

3. Drain piping

•Check the level of the air conditioner.

(Check that it is horizontally set or the drain port side of the air conditioner is set with an inclination within 1˚ downward.)

•Be sure to make a check port to the lower ceiling part of the drain up kit.

*Using the hose band, tighten the drain port and drain inlet of the drain pan. Also, be sure to set the screw section of the hose band toward upper side.

4. Cabling (See Fig. 2.)

•Remove cover of the electric parts box of the air conditioner body.

•Insert 3P connector (BLUE) of the drain up kit into the terminal No. CN068 (BLUE) in the electric parts box.

•Remove the short circuit connector (No. CN030) on the P.C. board in electric parts box.

•Insert 3P connector (RED) of the drain up kit into the terminal No. CN030 (RED) (Short-circuit connector is not used.)

•Clamp the cable in the electric parts box.
