4 DRAIN PIPING WORK
CAUTION
Install the drain pipe in accordance with the Installation Manual so that the water is drained completely, and insulate the pipes so that no condensation forms them.
Improper pipe installation could result in water leaking indoors on furniture, etc.
REQUIREMENT
•Insulate indoor drain pipes completely.
•Insulate the connection with the indoor unit. Incomplete insulation could result in condensation forming.
•Make sure that the drain pipe slopes downwards at a rate of 1/100 or more, do not route the drain pipe over another pipe, and do not create a trap.
These can all cause unusual sounds.
•Do not apply undue force to the drain pipe connection.
NG
Do not let the drain pipe slope upwards.
Do not leave the end of the drain hose in water. 
NG
Do not leave any undulations in the drain pipe.

Piping and Insulation
Arrange for the following materials on site for the pipe installation and insulation work.
Piping | Hard polyvinyl chloride pipe :nominal dia. (inner dia.) ; Ø20mm |
|
|
Heat insulator | Vesicant polyethylene : Thickness ; 10mm |
|
|
•When extending the drain hose, make the connection as shown in the figure at right.
REQUIREMENT
•Using adhesive agent for vinyl chloride, connect the hard vinyl chloride pipes certainly so that water does not leak.
•It requires several times to dry and harden the adhesive agent. (Refer to Guide Manual of the adhesive agent.) In this time, be sure not to apply force to the connecting section with the drain pipes.
•Because the drain is a gravity drain, the pipes outside of the unit must have a downward slope.
•Once the piping work is complete, pour water in the drain pan and make sure that the water drains completely.

Pipe and Drain hose formation
The drain pipe can be routed out of the rear, left, or right side of the unit.
When routing the drain pipe out the left or right side, align the pipe and drain hose as shown in the figure at right.
Make sure that the hose does not stick out the rear of the unit.
