Inspect the drainage conditions during cooling operation. Refer to the section of “TEST OPERATION” for details.
INSTALLING THE DUCT
• Connect the duct as indicated below.
<Air inlet side>
• Connect the duct to the inlet flange.
<Air outlet side>
• Connect the duct to the outlet flange.
• Wrap the outlet flange and the duct connection with aluminum tape or something similar to prevent air leakage.
• Connect the outlet flange and the unit using the screws.
NOTE
• Air filter is not a standard accessory, but please mount it at the air inlet side of the duct system.
• Insulate the duct to prevent condensation. (Material: glass wool or polyethylene foam, 25 mm thick)
• When soldering ducts, etc., wrap the product to prevent spartering.
ELECTRIC WIRING WORK
• All locally supplied parts and materials and electric works must conform to local codes.
• Use copper wire only.
• For electric wiring work, refer also to “WIRING DIAGRAM” attached to the unit body.
• For remote controller wiring details, refer to the installation manual attached to the remote controller.
• All wiring must be performed by an authorized electrician.
• A circuit breaker capable of shutting down power supply to the entire system must be installed.
• The resistance of the grounding must not exceed 100
Ω
.
• Ground the air conditioner.
Do not connect the ground wire to gas or water pipes, lightning conductor or telephone ground wire. Incomplete grounding may
cause electric shocks.
• Gas pipe - Ignition or explosion may occur if the gas leaks.
• Water pipe - Hard vinyl tubes are not effective grounds.
• Lightning conductor or telephone ground wire - Electric potential may rise abnormally if struck by a lightning bolt.
• If the fan rotates in reverse, adjust the phase sequence of the electric wires.
