Installation Procedure
Drain pipe
! Caution
In order to drain water normally, the drain pipe shall be processed as specified in the installation manual and shall be thermal insulated to avoid dew generation. Improper hose connection may cause indoor water leakage.
Requirements
The indoor drain pipe shall be thermal insulated.
The connection part between the drain pipe and the indoor unit shall be insulated so as to prevent dew generation.
The drain pipe shall be slant downwards (greater than 1/100). The middle part shall not be of S type elbow, otherwise abnormal sound will be produced.
The horizontal length of the drain pipe shall be less than 20 m. In case of long pipe, suppo- rts shall be provided every 1.5 ñ 2m to prevent wavy form.
Central piping shall be laid out according to the following figure.
Take care not to apply external force onto the drain pipe connection part.
