(d) Installation of drain up kit

Fix the drain up kit on the right side of the

inside unit with tap screws.

Insert the drain hose fully and securely to

the drain sockets of the inside unit and the

drain up kit.

Connect the drain up kit's connectors for the

drain pump (red color 2P) and the float

switch (black 2P) to the connectors of the

control box. (The control box's connectors

for the drain pump and the float switch are

also red and blace respectively.) Note that

the control's connector for the float switch

is already connected to the inside unit's

connector for the float switch, so disconnect

them and connect it to the drain up kit's

connector for the float switch and fix it with the wire clamp.
