Vacuuming And Charging
Vacuuming is necessary to eliminate all moisture and air from the system. The Series II Condensing Unit is
provided with flare valve fittings and charging nipples.
Vacuuming
After the system pipings are properly connected, connect the
flexible hoses to the correct charging nipples as shown in the
diagrams. Ensure that flexible hose from charging nipples are
connected to vacuum pump via standard servicing valves and
pressure gauges (gauge manifold). Vacuum the air conditioner
system to at least 500 microns Hg.
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 that
refrigerant charges is of correct quantity by monitoring running
current and suction and liquid line pressures. Suction and
discharge pipe pressures 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.
