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.

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 drain hole
II
and
III
. After insertion,
turn them about 40° clockwise.

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
I
,
II
, 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.
