(2) Check the smooth draining of the piping on completion of
the installation of the piping.
[Before electrical work]
CAUTION
• A licensed electrical engineering technician must con-
duct electrical wiring work (including grounding work).
• If no licensed electrical engineering technician is avail-
able, take steps 3 and 4 after the test operation of the air
conditioner is finished.
1. Remove the control box lid, and connect the single-
phase electric wires to terminals L and N of the termi-
nal block and the ground wire to the ground terminal.
Perform wiring according to 10-1 CONNECTING POWER
SUPPLY, GROUND, REMOTE CONTROLLER, AND
TRANSMISSION WIRING in 10. WIRING EXAMPLE
AND HOW TO SET THE REMOTE CONTROLLER.
CAUTION
• In order not to impose tension on the wire connections, per-
form clamping securely with the provided clamp (8) specified
in 3 in 10-1 CONNECTING POWER SUPPLY, GROUND,
REMOTE CONTROLLER, AND TRANSMISSION WIRING.
2. Check that the control box lid is closed before turning the
air conditioner ON.
3. Provide approximately one liter of water gradually into
the drain pan through the water inlet on the bottom of the
drain socket or the outlet. Make sure that the water is not
spilled onto the drain pump.
4. The drain pump will operate with the power turned ON.
Check that the pump drains water smoothly. (The drain
pump will stop automatically in 10 minutes.)
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 lid to the original position.
[After electrical work]
• After completion of 8. DUCT WORK provide approximately
one liter 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 heat insulation work on the follow-
ing 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 heat insulate the metal clamp (1) and drain hose
(2).
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
datasheet 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
hanging 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 metal
plate of a wooden structure, separate the duct and wall elec-
trically.
• Be sure to heat insulate the duct for the prevention of dew
condensation. (Material: Glass wool or styrene foam; Thick-
ness: 25 mm)
• 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 effi-
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.
