CHECK AND TEST 1

Note


Step 1

Discharge refrigerant.
Cut off the charging
tube with pliers.

Step 2

Click below link to get more details for brazing requirements, go to Annex B1

NOTE

Step 5

Install quick connector
onto re-brazed pipe.

Step 6
Inject nitrogen gas
with 1.57Mpa pressure
through quick connector
into pipe.

Step 7

Please follow drawing below to perform a leakage test for brazed joints in the compressor niche.

DIAGNOSIS 1

PROCEDURE 2

Note


Step 1

Clean paint off of
brazed joint.

Step 2
Cut off brazed joint
with leakage

Step 3

Use a larger copper tube to connect 2 ends of brazed joint.

Step 4
Braze the 2 ends.

CHECK AND TEST 2

Step 1

Inject nitrogen at 1.57Mpa
through quick connector
into pipe.

DIAGNOSIS 2


CHECK AND TEST 3


Step 1

Braze a piezometer
onto processing tube of
compressor.

Step 2

Charge nitrogen at
1.57Mpa through quick
connector into pipe.

Step 3

Do leakage test on
brazing points and
piezometer.

DIAGNOSIS 3

CHECK AND TEST 4

Step 1

Give the system
1.57Mpa Nitrogen, and
then observe if there is
rust and/or spotted holes
on pipes of compressor
niche and evaporator.

Note

Photo is not accurate,
but just to show the
technique.


Step 2
If it seems like there is a
hole there, apply soapy
water to the rusty area to
check.

DIAGNOSIS 4

PROCEDURE 2

Step 1

Clean paint off of
brazed joint.

Step 2
Cut off brazed joint
with leakage

Step 3

Use a larger copper
tube to connect 2
ends of brazed joint.

Step 4
Braze the 2 ends.

PROCEDURE 3

Step 1

Clean paint off brazed
joint of drying-filter.

Step 2

Cut off drying-filter.

Step 3

Cut off capillary and
shake to remove the cut
end.

Step 4

Braze one new drying- filter.

Step 5

Inject nitrogen (1.57Mpa) through quick connector into pipe for at least 3 min to blow remaining refrigerant away.

Step 6

Add quick connector onto processing pipe of drying-filter.

Step 7

Perform leakage test on
brazed joints of drying
filter and compressor
processing pipe.

Step 8

Vacuum and recharge.

Step 9

Block processing pipe twice with locking pliers.

Step 10

Leave locked pliers
attached to second
block and shake to cut
off the remaining pipe.

Step 11

Braze the ends and remove the pliers.
