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 wiring.

6. Put the control box cover to the original position.

[After electrical work]

• After completion of

8. DUCT WORK

provide

approximately

1/4 gal (1 ) 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

OPERATION

. Make sure that the water is not spilled onto the

electric parts of the drain pump and others.

(3) Be sure to conduct thermal insulation work on the fol-

lowing portions, or otherwise water leakage may occur
as a result of dew condensation.

• Drain piping indoors
• Drain socket

• On completion of the drainage check, refer to the follow-

ing illustration, and use the provided large sealing pad
(6) and insulate the metal clamp (1) and drain hose (2).

DUCT WORK

Pay utmost attention to the following items and conduct
ductwork.

• Check that the duct will not be in excess of the setting range

of external static pressure for the unit. (Refer to Engineering
Data 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, protect the opening of the duct so

that the sputter will not come in contact with the drain pan or
the filter.

• If the metal duct pass through a metal lath, wire lath, or metal

plate of a wooden structure, separate the duct and wall elec-
trically.

• Be sure to insulate the duct for the prevention of dew conden-

sation. (Material: Glass wool or styrene foam; Thickness:
1 in. (25 mm))

• Be sure to attach a field supplied air filter to the air inlet of the

unit or field supplied inlet in the air passage on the air suction
side. (Be sure to select an air filter with a duct collection effi-
ciency of 50 weight percent.)

• Explain the operation and cleaning method of the field sup-

plied components (i.e., the air filter, air inlet grille, and air out-
let 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 supplied duct in alignment with the inner

side of the flange.

• Connect the flange and unit with the flange connection screw
