• 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 spatter 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)
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 sid es.
• Connect the field supply duct in alignment with the inner side
of the flange.
• Connect the flange and unit with the flange connection screw
(field supply).
• Wrap aluminum tape around the flange and duct joint in order
to prevent air leakage.

CAUTION
Connect the flange and unit with the flange connection screw

GENERAL INSTRUCTIONS
1
Shut off the power before starting any work.
• All field supplied parts and materials and electric works must
conform to local codes.
• Use copper wire only.
• For electric wiring work, refer to also "Wiring diagram"
attached to the el. compo. box lid.
• For remote controller wiring details, refer to the installation
manual attached to the remote controller.
• All wiring must be performed by an authorized electrician.
This system consists of multiple indoor units. Mark each
•
indoor unit as unit A, unit B..., and be sure the terminal board
wiring to the outdoor unit and BS unit are properly matched.
If wiring and piping between the outdoor unit and an indoor
unit are mismatched, the system may cause a malfunction.
A circuit breaker capable of shutting down power supply to
•
the entire system must be installed.

• Refer to the installation manual attached to the outdoor unit
for the size of power supply wiring connected to the outdoor
unit, the capacity of the circuit breaker and switch, and wiring
instructions.
• Be sure to ground the air conditioner.
• Do not connect the ground wire to gas and water pipes,
lightning rods, or telephone ground wires.
Gas pipes : might cause explosions or fire if gas leaks.
•
Water pipes : no grounding effect if hard vinyl piping is used.
•
•
Telephone ground wires or lightning rods : might cause
abnormally high electric potential in the ground during
lighting storms.
