AIR RECHARGING
IN COMPRESSOR
Test the refrigeration
system by connecting
it electrically
before refilling operation.
This is necessary
to ascertain the
function
of the motor-compressor
and identify the defects
immediately,
if the defects have been found, empty the old
system of eventual
R-t 2 residue by breaking
off the end of
the extension
piece at its narrow point. (Figure 1)
Replace the filter and any damaged
component&
Unsolder
and pull off the piece
remaining
inside the service tube and
then attach an extension completely
with male Hansen and
last, solder it to the same tube again. (Figure 2)
It is necessary
to execute the soldering operation
with
valve open so that the fumes caused
by oil residue can
come out freely without
blowholes
between two tubes
during heating the point to be soldered.
The extension
fitted with the male Hansen is connected
to
the female
fitting of the vacuum
pump tube. (Figure 3)
Air evacuating
from the system
begins as soon as the
pump starts. The refrigeration
system must be kept under
vacuum
until the reading on the low-pressure
gauge
indicates vacuum
(0 absolute,
-1 atm., -760 mm hg) in any
case it is advisable
to keep the pump running for about
30 minutes.
