Installation of indoor unit
The drainage can be checked with the water level change
in the drain pan through the water inlet.
CAUTION
• Do not touch the drain pump.
Otherwise, an electric shock may be received.
• Do not impose external force on the float switch.
Otherwise, a failure may result.
5. On completion of the drainage check, shut off the power
supply and disconnect the power supply line.
6. Put the control box cover to the original position.
[After electrical work]
• After completion of 8. DUCT WORK provide approximately
1/4 gal of water gradually into the drain pan through the
water inlet on the bottom of the drain socket, and check that
the water is drained while the air conditioner is in cooling
operation according to 11. FIELD SETTING and 12. TEST
RUN. Make sure that the water is not spilled onto the electric
parts of the drain pump and others.
(3) Be sure to conduct heat insulation work on the follow-
ing portions, or otherwise water leakage may occur as
a result of dew condensation.

8. DUCT WORK
Pay the utmost attention to the following items and conduct
the ductwork.
• Check that the duct will not be in excess of the setting range
of external static pressure for the unit. (Refer to the technical
data sheet for the setting range. Each model has each setting
range of external static pressure.)
• Attach a canvas duct each to the air outlet and air inlet so that
the vibration of the equipment will not be transmitted to the
duct or ceiling.
Use a sound-absorbing material (insulation material) for the
lining of the duct and apply vibration insulation rubber to the
suspension bolts.
• At the time of duct welding, perform the curing of the duct so
that the sputter will not come in contact with the drain pan for
the filter.
• If the metal duct pass through a metal lath, wire lath, or
plate of a wooden structure, separate the duct and
trically.
• Be sure to heat insulate the duct for the prevention of dew
condensation. (Material: Glass wool or styrene foam; Thick-
ness: 31/32 in.)
• Be sure to attach the field supply air filter to the air inlet of the
unit or field supply inlet in the air passage on the air suction
side. (Be sure to select an air filter with a duct collection
ciency of 50 weight percent.)
• Explain the operation and washing methods of the locally
procured components (i.e., the air filter, air inlet grille, and air
outlet grille) to the customer.
• Locate the air outlet grille on the indoor side for the preven-
tion of drafts in a position where indirect contact with people.
• The air conditioner incorporates a function to adjust the fan to
rated speed automatically. (11. FIELD SETTING)
Therefore, do not use booster fans midway in the duct.
Connection method of ducts on air inlet and outlet sides.
• Connect the field supply duct in alignment with the inner side
of the flange.
• Connect the flange and unit with the flange connection screw
(3).
• Wrap aluminum tape around the flange and duct joint in order
to prevent air leakage.
