Equipment Needed for Evacuation & Recharging:
1. 1 - R-410A Refrigerant tank properly labeled and
color coded. (Do not mix refrigerants in the same
2. 1 - Recovery/Recycling unit.
5. 1 - External vacuum pump.
6. Process tube adapter kit (Robinair No.12458)
8. Pinch-off tool capable of making leak proof seal.
10. Complete brazing torch set.
12. Grit cloth or Scotch-Brite.
13. 45% silver solder and flux.
14. 1 - R-410A Gauge and Manifold set.
Installing and Operating Evacuation and
1. Disconnect electrical supply to unit.
2. Recover refrigerant before servicing the unit.
(See Recovering Refrigerant on page 6-12)
3. Repair or replace components as needed. Install
filter-drier into the sealed system.
4. Attach process tube adapter to filter-drier process
5. Attach the R-410A service gauge manifold set to
system in following order:
Use the shortest hoses available for connecting
the evacuation and recharging equipment.
a. Hose from process tube adapter to center port
before hand shut-off valve.
b. Low-side hose to vacuum pump
c. High-side hose to refrigerant tank. Note that the
refrigerant tank valve is at the bottom
6. Close the refrigerant tank valve.
7. Open the high and low side valves on R-410A gauge
set manifold. Open hand valve for hose leading to
8. Turn on vacuum pump. Operate vacuum pump for
