Installation Manual
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 drain
hole II and III. After insertion, turn them about 40˚ clockwise.
II
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 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.
