To connect the piping on left side, left-back, or left-
bottom

INFORMATION

The factory default is right-side piping. For left-side piping,
remove  the  piping  from  the  right  side  and  install  it  on  the
left side.

1

Remove  the  insulation  fixing  screw  on  the  right  side  and
remove the drain hose.

2

Remove the drain plug on the left side and attach it to the right
side.

NOTICE

Do  NOT  apply  lubricating  oil  (refrigerant  oil)  to  the  drain
plug when inserting it. The drain plug may deteriorate and
cause drain leakage from the plug.

3

Insert the drain hose on the left side and do not forget to tighten
it with the fixing screw; otherwise water leakage may occur.

Piping installation

6.1

Preparing refrigerant piping

6.1.1

Refrigerant piping requirements

NOTICE

The  piping  and  other  pressure-containing  parts  shall  be
suitable  for  refrigerant.  Use  phosphoric  acid  deoxidised
seamless copper for refrigerant.

▪ Foreign materials inside pipes (including oils for fabrication) must

be ≤30 mg/10 m.

Refrigerant piping diameter

Use the same diameters as the connections on the outdoor units:

Class

L1 liquid piping

L1 gas piping

20~42

Ø6.4

Ø9.5

6.1.2

Refrigerant piping insulation

▪ Use polyethylene foam as insulation material:

▪ with a heat transfer rate between 0.041 and 0.052 W/mK (0.035

and 0.045 kcal/mh°C)

▪ with a heat resistance of at least 120°C

▪ Insulation thickness

If  the  temperature  is  higher  than  30°C  and  the  humidity  is  higher
than RH 80%, the thickness of the insulation materials should be at
least  20  mm  to  prevent  condensation  on  the  surface  of  the
insulation.

6.2

Connecting the refrigerant piping

DANGER: RISK OF BURNING/SCALDING

WARNING

▪ Only  use  R32  as  refrigerant.  Other  substances  may

cause explosions and accidents.

▪ R32  contains  fluorinated  greenhouse  gases.  Its  global

warming  potential  (GWP)  value  is  675.  Do  NOT  vent
these gases into the atmosphere.

▪ When  charging  refrigerant,  ALWAYS  use  protective

gloves and safety glasses.

6.2.1

Guidelines when connecting the
refrigerant piping

Take the following guidelines into account when connecting pipes:

▪ Coat  the  flare  inner  surface  with  ether  oil  or  ester  oil  when

connecting  a  flare  nut.  Tighten  3  or  4  turns  by  hand,  before
tightening firmly.
