carbon steel (whose surface is zinc plated or undergoes other
rustproof treatment) or stainless steel.
The treatment of the ceiling varies between buildings. For
detailed measures, consult with the fitting-out staff.
Fix the pendant bolts firmly and reliably in light of the specific
situation.
Installation of the pendant bolt in different environments.
A. Wooden structure
Put rectanglar sticks across the beams, and set pendant bolts.
B. New concrete roughcast
Use embedded bolts, embedded pulling plugs, and embedded
stick harness.
D. Steel beam and girder structure
Set and use supportive angle steel.
Use a hoisting device to hoist the indoor unit, align it with the
installation screw, adjust the horizontality and then tighten it.
C. New concrete roughcast
Set it with embedded bushes or embedded bolts.

Installation Manual
The duct design must comply with the national heating air
conditioner pipeline design specifications.
The duct accessories and materials must be produced by
professional manufacturers.
In order to prevent air flow shorting, do not keep the air inlet pipe
near the air outlet pipe.
Install a filter at an easy-to-maintain place such as intake pipe.
(Otherwise, the duct will gather on the air heat exchanger and
lead to fault and water leak of the air conditioner.)
In order to suppress noise effectively, install noise suppression
and sound insulation devices, especially in the noise-sensitive
spaces such as meeting rooms.

Key points of duct connection
For connection of the flange plane, use non-flammable canvas
adapter to prevent transmission of vibration. For its size, see the

site) for connection.
All pipelines must be connected closely and soundly without
leak of air. The pipelines must be adiabatic and free from
condensation.
