Use Φ10 or bigger screws. The screw material is high-quality

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

indoor unit outline diagram. Use M6X20 screws (configured on

site) for connection.

All pipelines must be connected closely and soundly without

leak of air. The pipelines must be adiabatic and free from

condensation.
