(4) Procedure
a) Prepare N
2
gas cylinders and attach a pressure regulator to a N
2
gas cylinder.
b) Connect the vacuum gauge to SV2. Open SV2.
c) Connect a pressure proof hose to the outlet of the pressure regulator, then slightly open
a valve on the top of the cylinder in order to purge air being in the hose. After purging,
close the valve.
d) Connect the other end of the hose to SV1 and fix it with a hose band.
e) Check that V1, V2, V3, B, SV1, are fully closed.
f) Open the V3, B valve and then open SV1.
Note: B valve shall be closed after solution charge in the Chiller.
g) Using the pressure regulator, charge a small amount of N
2
gas into the Chiller.
h) Watch the vacuum gauge during charging of N
2
gas. When the pressure inside the Chiller
reaches to required pressure, close SV1, V3, and B valve, and then close the valve of the
cylinder.
i) Remove the hose from SV1 and place a cap of the service valve to the service valve.
j) Remove the pressure regulator, and vacuum gauge.
k) Close SV2.
