The compressor is charged with sufficient polyol
ester oil for line set lengths up to 50'. If line set
lengths longer than 50' will be required, add 1 oz. of
oil for every additional 10' of line set. Do not add any
more than 7 oz. of oil. Copeland has approved Mobil
EAL
TM
Arctic 22CC and ICI EMKARATE
TM
RL32CF for
use with these compressors when oil must be added
in the field.
The following procedure is intended as a general guide
and is for use on expansion valve systems only. For best
results, indoor temperature should be 70° – 80°F. Be sure
to monitor system pressures while charging.
1. Record outdoor ambient temperature using a digital
thermometer.
2. Attach high pressure gauge set and operate unit for
several minutes to allow system pressures to stabilize.
3. Compare stabilized pressures with those provided in
Table 4. Minor variations in these pressures may be
expected due to differences in installations. Significant
differences could mean that the system is not properly
charged or that a problem exists with some other
component in the system. Pressures higher than
those listed indicate that the system is overcharged.
Pressures lower than those listed indicate that the
system is undercharged. A temperature/pressure
chart for R410A refrigerant is provided in Table 5.
Verify adjusted charge using the approach method.
4. Outdoor temperature should be 60°F or above.
For
best results, use the same digital thermometer
used to check outdoor ambient temperature to
check liquid line temperature.
Verify the unit charge
