3-5. Checking the Drainage

After wiring and drain piping are completed, use the following
procedure to check that the water will drain smoothly. For this,
prepare a bucket and wiping cloth to catch and wipe up spilled
water.
(1) Connect power to the power terminal board (R, S
terminals) inside the electrical component box.
(2) Short the check pin (CHK) on the indoor control board and
operate the drain pump.
CAUTION
Be careful since the fan will start when you short the pin on
the indoor control board.
(3) Pour about 1,200 cc of water into the drain pan using a
siphon pump through the air outlet grille. (Fig. 3-15)

Check the water flow through the transparent drain pipe
and see if there is any leakage.
(4) When the check of drainage is complete, open the check
pin (CHK) and remount the insulator.
CAUTION
Use 4 × 8 tapping screws to fasten the drainage cover. If
the screws used are longer than 8 mm, it may make a hole
in the drain pan and cause leakage.
Removing the side panel
(1) Push the tab on both sides of the side panel inward (a)
to disengage the tab (first stage) and move the panel

3-6. Preparation for Suspending

This unit uses a drain pump. Use a carpenter's level to check
that the unit is level.

3-7. Suspending the Indoor Unit

(1) Follow the diagrams to make the holes in the ceiling.
(2) Depending on the ceiling type:
● Insert suspension bolts as shown in Fig. 3-17
Hole-in-anchor
Hole-in-plug
or
● Use existing ceiling supports or construct a suitable
support as shown in Fig. 3-18.
WARNING
It is important that you use extreme care in supporting
the indoor unit from the ceiling. Ensure that the ceiling is
strong enough to support the weight of the unit. Before
hanging the unit, test the strength of each attached
suspension bolt.
