If line length is less than 15 ft., remove this amount.

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

in the field.
If the system is void of refrigerant, the unit must be
returned to the warehouse for exchange. Do not install
a unit which has been delivered void of refrigerant.

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
below in Table 5. 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 7 on page 12.
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
using the approach method. The difference between
