(1) As shown in the figure above, connect the vacuum
pump valve with gauge to the vacuum pump.
Note: When evacuating refrigeration and air
conditioning equipment that uses R1 , R
or
any other old refrigerant, attach a 5/1 flare
female x 5/1 flare male adapter with different
diameters to the intake of the pump.
Note: When continuing with the charging of the
chlorofluorohydrocarbon (freon) gas after the
evacuation operation, this job is made easier
by changing the charging hose (yellow) to the
AS VP 85MK hose for vacuum pumps.
( ) Proceed with the evacuation by following the directions
in the Instruction Manual of the vacuum pump.
( ) When the degree of vacuum indicated in the manual
of the refrigeration and air conditioning equipment
manufacturer has been reached, close the ball valve.
( ) Leave the units standing for at least 5 minutes, and
check that the pointer of the vacuum gauge does not
swing back.
(5) If the pointer should swing back, it means that there is
a leak somewhere so inspect the piping joins and other
such areas, make repairs, and resume the evacuation.
( ) Upon completion of the work, disconnect the hose which
is connected to the vacuum pump valve with gauge.

W arning
The vacuum gauge will be broken if a
positive pressure is applied to it.
As such, when the evacuation work is
completed, disconnect the hose which is
connected to the positive pressure side.
The vacuum gauge may malfunction or fail
if it is dropped or subjected to vibration.
If this gauge has been dropped or knocked
into something, immediately inspect it for
damage, cracks and deformation.
