Haier AE122BCAAA (H2EM-18H03) manual Installation procedureInstall indoor unit, Confirm drainage

Installation procedureInstall indoor unit

*Notice

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.

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.

Material of connection pipe and thermal insulation
Material of connection pipe	Stiff PVC pipe VP 20mm (inside diameter)
Material of thermal insulation	Foam polyethylene pipe, thickness over 10mm

Confirm drainage

Perform test run to insure the condition of drainage, the connection part of the connection should not leak water. The confirmation must be performed even if install in winter.
