datasheet for the setting range.)
r 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.
r At the time of duct welding, perform the curing of the duct
so that the sputter will not come in contact with the drain
RCPHQTVJGƂNVGT
r If the metal duct passes through a metal lath, wire lath, or
plate of a wooden structure, separate the duct and wall
electrically.
r Be sure to heat insulate the duct for the prevention of dew
condensation. (Material: Glass wool or styrene foam; Thick-
ness: 31/32 in. (25 mm))

r Multiple number of indoor units are connected to one out-
door unit. Name each indoor unit as A-unit, B-unit ….. and
the like. When these indoor units are wired to the outdoor
unit and the Branch Selector unit, always wire the indoor
unit to the terminal indicated with the same symbol on the
terminal block. If the wiring and the piping are connected
to the different indoor units and operated, it will result in
malfunction.
r Make sure to ground the air conditioner.
Grounding resistance should be according to applicable
legislation.
