Installing Outdoor Unit
● When installing the outdoor unit, refer to "Precautions for Selecting the Location" and the "Indoor/Outdoor Unit
Installation Drawings".
● If drain work is necessary, follow the procedures below.

Drain Work
● Use drain plug for drainage.
● If the drain port is covered by a mounting base or floor surface, place additional foot bases of at least 3-15/16in in
height under the outdoor unit's feet.
● In cold areas, do not use a drain hose with the outdoor unit. (Otherwise, drain water may freeze, impairing
heating performance.)
1. Insert drain receiver (C) onto drain socket (A) and drain cap (B) beyond 4
projections around drain socket and drain cap.
2. Insert drain socket and drain caps into their matching drain hole ; Drain socket
(A) into drain hole I and drain caps (B) into drain hole II and III. After insertion,
turn them about 40° clockwise.

3. Connect vinyl hose on the market (internal diameter of 1 inch) to drain socket (A).
*If the hose is too long and hangs down, fix it carefully to prevent the kinks.
NOTE
If the drain holes of the outdoor unit are covered with the mounting bracket or the floor, raise the unit to provide a
space of more than 3-15/16 inch under the leg of the outdoor unit.

Refrigerant Piping
CAUTION
1) Use the flare nut fixed to the main unit to prevent cracking of the flare nut by age deterioration.
2) To prevent gas leakage, apply refrigeration oil only to the inner surface of the flare. (Use refrigeration oil for R410A.)
3) Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and gas leakage.
Align the centers of both flares and tighten the flare nuts 3 or 4 turns by hand. Then tighten them fully with the
torque wrenches.
Do not apply refrigeration oil to the flare
nut. Avoid tightening with over torque.
