Check the sound of discharging gas from the
compressor when rubber caps are removed.
Take out the dryer from the package just before
use.
Note:
Set the compressor in the compressor room.
Joint the discharge pipe and compressor with
brazing.
D joint must place in compreesor room at
Cooling unit.
From the process of removing compressor until the process of setting compressor and dryer
(just before vacuum pumping process).
From the time just after pipe cleaning is completed until the process of setting compressor
and dryer (just before vacuum pumping process).
If pipe are being kept open to air, moisture will go into the refrigerating unit and it may cause a
malfunction in the refrigerating unit again.
Note:
Joint the gascharge pipe with brazing.
Remove rubber caps of compressor just before
compressor is installed.
Shape and length of pipe must be suitable
with Discharge pipe.
If there is no sound of discharging gas, never
use the compressor.
Joint the suction pipe and compressor with
brazing.
Insert the capillary tube ±15mm into the
dryer.
Bend the capillary tube at an obtuse angle of about 120o along 15mm from the cut end before
inserting the tube into the dryer. Then insert the tube until it is stopped by the bend. This is to
prevent the tube from going into the dryer too far and breaking the filter placed inside. Also this
insure that the tube goes into the dryer far enough not to be clogged with the filler metal during
brazing.
Break the package of dryer just before
use. This is to prevent dryer from
absorbing moisture in the air.
If the
package is bruise, as air has leakage
into the package, never use the dryer in
the package.
use dryer within the term of validity
(which is marked in the package).
