CAUTION

▪

Use the flare nut fixed to the unit.

▪

To prevent gas leakage, apply refrigeration oil ONLY to the inside of the flare. Use
refrigeration oil for R32.

▪

Do NOT reuse joints.

CAUTION

▪

Do NOT use mineral oil on flared part.

▪

NEVER install a drier to this R32 unit to guarantee its lifetime. The drying material
may dissolve and damage the system.

NOTICE

Take the following precautions on refrigerant piping into account:

▪

Avoid  anything  but  the  designated  refrigerant  to  get  mixed  into  the  refrigerant
cycle (e.g. air).

▪

Only use R32 when adding refrigerant.

▪

Only use installation tools (e.g. manifold gauge set) that are exclusively used for
R32 installations to withstand the pressure and to prevent foreign materials (e.g.
mineral oils and moisture) from mixing into the system.

▪

Install the piping so that the flare is NOT subjected to mechanical stress.

▪

Protect  the  piping  as  described  in  the  following  table  to  prevent  dirt,  liquid  or
dust from entering the piping.

▪

Use caution when passing copper tubes through walls (see figure below).

INFORMATION

Do NOT open the refrigerant stop valve before checking the refrigerant piping. When
you need to charge additional refrigerant it is recommended to open the refrigerant
stop valve after charging.

7.2.3 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.
