CAUTION
Danger of Equipment Damage.
Avoid deep vacuum operation. Do not use compres-
sors to evacuate a system.
Extremely low vacuums can cause internal arcing and
compressor failure.
Damage caused by deep vacuum operation will void
warranty.
7 − Shut off the nitrogen cylinder and remove the manifold
gauge hose from the cylinder. Open the manifold gauge
valves to release the nitrogen from the line set and in-
door unit.
8 − Reconnect the manifold gauge to the vacuum pump,
turn the pump on, and continue to evacuate the line set
and indoor unit until the absolute pressure does not rise
above 500 microns (29.9 inches of mercury) within a
20−minute period after shutting off the vacuum pump
and closing the manifold gauge valves.
9 − When the absolute pressure requirement above has
been met, disconnect the manifold hose from the vacu-
um pump and connect it to an upright cylinder of R−410A
refrigerant. Open the manifold gauge valves to break the
vacuum from 1 to 2 psig positive pressure in the line set
and indoor unit. Close manifold gauge valves and shut
off the R−410A cylinder and remove the manifold gauge
set.

Polyol Ester Oil
IMPORTANT
Mineral oils are not compatible with R−410A. If oil
must be added, it must be a polyol ester oil.
The compressor is charged with sufficient polyol es-
ter oil. If oil must be added to the compressor in the
field, Copeland has approved Mobil EALt Arctic
22CC and ICI EMKARATEt RL32CF.
This system uses R−410A refrigerant which operates at
much higher pressures than HCFC−22. The provided liquid
line filter drier is approved for use with R−410A. Do not re-
place it with components designed for use with HCFC−22.
This unit is NOT approved for use with coils which use capil-
lary tubes as a refrigerant metering device.
Factory Charge
Units are factory-charged with the amount of R−410A refrig-
erant indicated on the unit rating plate. This charge is based
on a matching indoor coil and outdoor coil with 15 ft. (4.6 m)
line set. For varying lengths of line set, refer to table 2 for re-
frigerant charge adjustment.

Ounces per 5 feet (g per 1.5 m) adjust
from 15 feet (4.6 m) line set*
3/8 in. (9.5 mm) 3 ounce per 5 ft. (85 g per 1.5 m)
NOTE − *If line length is greater than 15 ft. (4.6 m), add this amount. If
line length is less than 15 ft. (4.6 m), subtract this amount.
