If  there  is  a  possibility  of  moisture  being  present  in  the  refrigerant  piping  (for
example,  water  may  have  entered  the  piping),  first  carry  out  the  vacuum  drying
procedure below until all moisture has been removed.

8.3.2 Precautions when checking the refrigerant piping

INFORMATION

Also read the precautions and requirements in the following chapters:

▪

"2 General safety precautions"

▪

"8.1 Preparing refrigerant piping"

 [

 91]

NOTICE

Use  a  2-stage  vacuum  pump  with  a  non-return  valve  that  can  evacuate  to  a  gauge
pressure of −⁠100.7 kPa (−⁠1.007 bar)(5 Torr absolute). Make sure the pump oil does
not flow oppositely into the system while the pump is not working.

NOTICE

Use  this  vacuum  pump  for  R32  exclusively.  Using  the  same  pump  for  other
refrigerants may damage the pump and the unit.

NOTICE

▪

Connect the vacuum pump to 

both

 the service port of the gas stop valve and the

service port of the liquid stop valve to increase efficiency.

▪

Make sure that the gas stop valve and liquid stop valve are firmly closed before
performing the leak test or vacuum drying.
