Installing Evacuation and Recharging Equipment
1. Disconnect refrigerator from electrical supply.
2. If compressor was replaced, install correct sized
process tube adaptor on process tube. If compres-
sor was not replaced, cut process tube with tubing
cutter leaving as much tube as possible and install
correct size process tube adaptor.
3. Install correct sized process tube adaptor on
high-side process tube.
4. Attach refrigeration service gauge manifold to
system in following order:
•
Low-side (compound gauge) hose to suction
side process tube adaptor.
•
High-side (pressure gauge) hose to high-side
process tube adaptor.
•
Center port manifold hose before hand shut-off
valve to charging cylinder.
•
Center port manifold hose after hand shut-off
valve to vacuum pump.
Evacuating System
CAUTION: R-134a systems are particularly
susceptible to moisture contamination which
can only be prevented by evacuating the system
for a minimum of 30 minutes to attain a
minimum 29.9 inch (500 micron or lower)
vacuum.
To achieve the required levels of evacuation, a properly
maintained two stage vacuum pump in good condition is
required. It is absolutely essential to maintain your
vacuum pump according to the manufacturer’s
instructions including required oil changes at the recom-
mended intervals. Vacuum pump oil should always be
changed after evacuating a contaminated system.
Vacuum pump performance should be checked
periodically with a micron gauge.
1. Make certain that charging cylinder valve, hand
shut-off valve, and manifold gauge valves are closed.
2. Start vacuum pump.
Equipment Needed for Evacuation & Recharging:
•
Heated charging cylinder
•
Standard 3-port manifold gauge set:
4 charging hoses
Tee fitting with valve core stem removed
(Robinair No. 40396)
Hand shut-off valve (Robinair No.40380)
•
Two stage vacuum pump
•
Process tube adapter kit (Robinair No. 12458)
•
Tubing cutter
•
Pinch-off tool capable of making leak proof seal
•
Complete brazing torch set
•
Small 3-corner file
•
Grit cloth or Scotch-Brite
•
45% silver solder and flux
3. Open hand shut-off valve and slowly open both
manifold valves, turning counterclockwise, for two
full rotations.
CAUTION: If high vacuum equipment is
used, just crack both manifold valves for a few
minutes and then open slowly for the two full
turns counterclockwise. This will prevent the
compressor oil from foaming and being drawn
into the vacuum pump.
4. Operate vacuum pump for minimum of 30 minutes
to minimum of 29.9” (500 micron) vacuum.
5. Close hand shut-off valve to vacuum pump. Watch
compound gauge for several minutes. If reading
rises, there is leak in system, go to step 6. If no
leak is indicated, stop vacuum pump. System is now
ready for charging.
6. If leak is indicated, stop vacuum pump and
introduce small charge of refrigerant into system
by cracking valve on bottom of charging cylinder
until system is pressurized to 40 or 50 lbs psig.
7. Leak test low-side. Close compound gauge.
Run compressor for few minutes and leak test high-
side. When leak is found, recapture refrigerant using
EPA approved recovery system Repair and go back
to step 1.
Charging The System
CAUTION: Check the serial plate for the correct
refrigerant type. It is extremely important to
verify the type of refrigerant in the system before
starting any sealed system repairs.
CAUTION: After charging the system with liq-
uid, be certain to wait at least 5 minutes before
starting the compressor to give the refrigerant
a chance to disperse throughout the system.
Otherwise the compressor could be damaged
by attempting to pump excessive quantities
of liquid.
Preparing The Charging Cylinder:
1. Make certain that hand shut-off valve to vacuum
pump is closed.
2. Close high-side manifold gauge valve.
3. Set charging cylinder scale to pressure indicated on
cylinder pressure gauge.
4. Observe refrigerant level in sight glass. Subtract
amount to be charged into system and note shut off
point.
5. Open charging cylinder valve slowly and allow proper
charge to enter system.
