Outdoor Unit Installation

1. 

Installing outdoor unit

1)  When installing the outdoor unit, refer to “Precautions for Selecting the Location” and the “Outdoor Unit Installation Drawings”.
2)  If drain work is necessary, follow the procedures below.

2. 

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 3-15/16 inch 

(100mm) in height under the outdoor unit’s feet.

• In cold areas, do not use a drain socket (A), drain caps (B) and 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 the other drain holes. After 

insertion, turn them about 40° clockwise.

(Be sure not to insert them into wrong drain 
holes, or there causes water leakage.)

(View from bottom)

NOTE

Check that the drain receiver (C) is correctly engaged with the projections of the drain socket (A) and drain cap (B). 
Otherwise, water leakage may result.

3)   Connect vinyl hose on the market (internal diameter of 1 inch (25mm)) to drain socket (A). 

(If the hose is too long and hangs down, fix it carefully to prevent the kinks.)

4)  Make sure that there is no water leakage from portion

, or 

III

.

NOTE

If the drain holes of the outdoor unit are covered with the mounting bracket or the floor, raise the unit to provide the space of 
more than 3-15/16 inch (100mm) under the leg of the outdoor unit.
