1)  Perform the drain piping work only when draining from one place.

2)  Provide drain piping before indoor and outdoor piping connection. 

3)  Attach the drain socket to one of the several drain holes.

 

Fix the drain socket into the drain hole of the base using the catches to secure 

it in place.

4)  Connect the soft PVC hose I.D.15 mm as shown in the illustration.

5)  Make sure to provide drain piping with a downhill grade for easy drain flow.

6)  Glue the drain caps to close all the other unnecessary holes with the glue 

(Prepare in the field).

Note:

Apply the glue securely, as the glue (Prepare in the field) will work as seal to 

prevent water from leaking.

Use the adhesive for the rubber and metal.

Attention

The outdoor unit is provided with several holes for drainage at the bottom to 

make drainage easier. 

The  drain  socket  is  used  to  close  the  unnecessary  holes  and  centralize  the 

drainage when using the drain tube at the installation place.

Do not to use the drain socket in cold region. The drain tube can be frozen.

(1) Drain socket

(L) Soft PVC hose

(2) Drain cap

 WARNING

To avoid risk of fire, embed or protect the refriger

-

ant piping. 

External  damage  on  the  refrigerant  piping  can  be 

cause of fire.

After  the  leak  test,  apply  insulat

-

ing material tightly so that there 

is no gap.

When the piping is to be attached to 

a wall containing metals (tin plated) 

or metal netting, use a chemically 

treated  wooden  piece  20  mm  or 

thicker between the wall and the 

piping or wrap 7 to 8 turns of insula

-

tion vinyl tape around the piping.

To  use  existing  piping,  perform 

COOL  operation  for  30  minutes 

and pump down before removing 

the old air conditioner. Remake 

flare  according  to  the  dimension 

for new refrigerant.
