Installation Procedures
• For proper drainage, the drainpipes should be connected according to the installation manual.
• Insulate the drainpipes to prevent exterior condensation.
• Follow local plumbing codes when connecting drainpipes.
Requirements:
• The drainpipe of the indoor unit should be insulated.
• Maintain a downward slope. Avoid waves or dips.
• The horizon length of the drainpipe should be kept with 65.6ft(20m). Under the condition of long pipes, supports can be
provided every 4.9-6.6ft(1.5~2m) as to avoid unevenness.
• The central piping should be connected according the following drawing.
• Take care not to apply external force on the connection of the drainpipes.
