—Replacement of the refrigeration cycle.
1. When replacing the refrigeration cycle, be sure to
Discharge the refrigerant system using a FreonTM
recovery System.
If there is no valve to attach the recovery system,
install one (such as a WATCO A-1) before venting
the FreonTM. Leave the valve in place after
servicing the system.
2. After discharging the unit completely, remove the
desired component, and unbraze the pinch-off
tubes.
3. Solder service valves into the pinch-off tube ports,
leaving the valves open.
4. Solder the pinch-off tubes with Service valves.
5. Evacuate as follows.
1) Connect the vacuum pump, as illustrated figure
14A.
2) Start the vacuum pump, slowly open manifold
valves A and B with two full turns counterclock-
wise and leave the valves open.
The vacuum pump is now pulling through valves
A and B up to valve C by means of the manifold
and entire system.
CAUTION: If high vacuum equip-
ment is used, just crack valves A
and B for a few minutes, then open
slowly with the two full turns counter-
clockwise. This will keep oil from foaming
and being drawn into the vacuum pump.
3) Operate the vacuum pump vaccum for 20 to 30
minutes, until 600 microns of vaccum is
obtained. Close valves A and B, and observe
vacuum gauge for a few minutes. A rise in pres-
sure would indicate a possible leak or moisture
remaining in the system. With valves A and B
closed, stop the vacuum pump.
4) Remove the hose from the vacuum pump and
place it on the charging cylinder. See figure
14B. Open valve C.
Discharge the line at the manifold connection.
5) The system is now ready for final charging.
6. Recharge as follows :
1) Refrigeration cycle systems are charged from
the High-side. If the total charge cannot be put
in the High-side, the balance will be put in the
suction line through the access valve which you
installed as the system was opened.
2) Connect the charging cylinder as shown in figure
33B.
With valve C open, discharge the hose at the
manifold connection.
3) Open valve A and allow the proper charge to
enter the system. Valve B is still closed.
4) If more charge is required, the high-side will not
take it. Close valve A.
5) With the unit running, open valve B and add the
balance of the charge.
a.
Do not add the liquid refrigerant to the Low-side.
b. Watch the Low-side gauge; allow pressure to
rise to 39lbs.
c. Turn off valve B and allow pressure to drop.
d. Repeat steps b. and c. until the balance of the
charge is in the system.
6) When satisfied the unit is operating correctly,
use the pinch-off tool with the unit still running
and clamp on to the pinch-off tube. Using a tube
cutter, cut the pinch-off tube about 2 inches from
the pinch-off tool. Use sil-fos braze and braze
pinch-off tube closed. Turn off the unit, allow it to
set for a while, and then test the leakage of the
pinch-off connection.
