07-115 SSHP_II 5/7/07 4:00 PM Page 54 CAUTION G Do not install an air bleeder tube as this may cause water to spray from the drain pipe outlet. (Fig. 3-100) G If it is necessary to increase the height of the drain pipe, the section directly after the connection port can be raised a maximum of 19-11/16 in. Do not raise it any higher than 19-11/16 in., as this could result in water leaks. (Fig. 3-101) G Do not install the pipe with an upward gradient from the connection port. This will cause the drain water to flow backward and leak when the unit is not operating. (Fig. 3-102) G Do not apply force to the piping on the unit side when connecting the drain pipe. The pipe should not U be allowed to hang unsupported from its connection to the unit. Fasten the pipe to a wall, frame, or other support as close to the unit as possible. (Fig. 3-103) 3-25. 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 (L1, L2 terminal) inside the electrical component box. (2) Remove the tube cover and through the opening, slowly pour about 43 oz. of water into the drain pan to check drainage. (3) Short the check pin (CN5 white) on the indoor control board and operate the drain pump. Check the water flow and see if there is any leakage. CAUTION Be careful since the fan will start when you short the pin on the indoor control board. (4) When the check of drainage is complete, open the check pin (CN5 white) and remount the insulator and drain cap onto the drain inspection port. CAUTION To mount the tube cover, use 5/16" (4 × 8 mm) tapping screws. Do not use long screws as they may puncture the drain pan and cause water leak-age. 54 Air bleeder Not good Fig. 3-100 Good 11-13/16 in. or less 19-11/16 in. or less Fig. 3-101 No good Upward gradient Fig. 3-102 Support pieces Good Fig. 3-103

CAUTION
●
Do not install an air bleeder tube as this may cause
water to spray from the drain pipe outlet. (Fig. 3-100)
●
If it is necessary to increase the height of the drain
pipe, the section directly after the connection port
can be raised a maximum of 19-11/16 in.
Do not raise it any higher than 19-11/16 in., as this
could result in water leaks. (Fig. 3-101)
●
Do not install the pipe with an upward gradient from
the connection port. This will cause the drain water
to flow backward and leak when the unit is not
operating. (Fig. 3-102)
●
Do not apply force to the piping on the unit side
when connecting the drain pipe. The pipe should not
be allowed to hang unsupported from its connection
to the unit. Fasten the pipe to a wall, frame, or other
support as close to the unit as possible. (Fig. 3-103)

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 (L1, L2
terminal) inside the electrical component box.
(2)
Remove the tube cover and through the opening,
slowly pour about 43 oz. of water into the drain pan to
check drainage.
(3)
Short the check pin (CN5 white) on the indoor control
board and operate the drain pump. Check the water
flow and see if there is any leakage.
CAUTION
Be careful since the fan will start
when you short the pin on the
indoor control board.
(4)
When the check of drainage is complete, open the
check pin (CN5 white) and remount the insulator and
drain cap onto the drain inspection port.
CAUTION
To mount the tube cover, use 5/16"
(4
×
8 mm) tapping screws.
Do not use long screws as they
may puncture the drain pan and
cause water leak-age.
