INSTALLATION MANUAL FOR INDOOR UNIT
Angle steel for support
Hoisting screw
Suspending bolt
Requirements:
The indoor side drain hose should be thermal insulated.
The parts connected with indoor unit should be thermal insulated. Improper thermal
insulation may cause dew-forming phenomenon.
The drain hose should be downwards slant (over 1/100) and there should be no
S-shaped bend. Otherwise, abnormal sound may occur.
The horizontal length of the drain hose should be less than 20m. If the connection
pipe is too long, the supporting frame should be set every 1.5~2m to prevent pipe
from rise and fall.
For the centralized connection pipe, please perform work as the following Figure
shown.
Pay attention not to exerting external force to the connection part of the drain hose.
In order to normally drain water, the drain hose should be mated according to the
installation manual. In order to avoid dew-forming, thermal insulation treatment
should be done.
Improper connection pipe may cause water enter indoor.
