FIELd CHARgINg
Unit performance, efciency, and life depends,
to a large extent, on a proper system charge.
Time spent on getting the charge right at start-up
will payoff in the long run. Operating conditions
such as voltage, air ow, evaporator coil size,
and indoor and outdoor temperature and humidity
all have an effect on the system pressures and
superheat conditions.
Condensing units are factory charged for the
outdoor and indoor unit with 25ft. (7.6m) of
refrigerant lines. Charge must be added for the
interconnecting tubing.
These units should be critically charged to ensure
proper performance. Some systems may require
additional charging of refrigerant, depending on
line set lengths.
FINAL INSPECTION
Do a nal visual inspection of the entire installation.
Complete any nal details and clean up.
Review Unit and Remote Control Operation with
the homeowner/user.
Ensure homeowner/user is provided with all
manuals, warranty cards, etc.
R = T X (L-25)ft
R(oz): Additional refrigerant to be charged
