VACUUMING AND CHARGING
Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with
flare valve fittings.
Vacuuming
Before vacuuming, perform leak check for refrigeration
circuit. After the system piping are properly connected,
connect the flexible hoses to the correct charging nipples as
shown in the diagram. Ensure that flexible hose from charging
nipples are connected to the vacuum pump via standard
servicing valves and pressure gauges (gauge manifold).
Vacuum the air conditioner system to at least 500 microns
Hg. Do not start the unit when the system is engaged in
vacuuming.
Charging
Before charging, the vacuum must be held at 500 microns Hg
for at least 15 minutes, then break vacuum by charging R-22
refrigerant. Operate the unit for 15 minutes and ensure the
refrigerant charges is of correct by monitoring running current,
gas and liquid line pressures. Suction and discharge pipe
pressure should be in the region of 75 psig and 275 psig
generally.
After ensuring the system is correctly charged, remove flexible
hose from charging nipples and replace caps.
