CHARGING WITH GAUGES
CAUTION
!
Refrigerant charging should only be carried out by a qualified air con-
ditioning contractor.
All units include a cooling charging chart for cooling. The heating
charging charts in Table 3 through Table 10 in this document use the
chart corresponding to the installed indoor coil. It can also be obtained
at
www.upgnet.com
under the Service Application Data section.
CAUTION
!
Compressor damage will occur if system is improperly charged. On
new system installations, charge system per tabular data sheet for
the matched coil and follow guidelines in this instruction.

Before using gauges, confirm that your gauges are accurate by
comparing the gauges against a calibrated pressure gauge that
has been calibrated against a national standard. If a calibrated
pressure gauge is not available, place a R-410A virgin refrigerant
container in a conditioned space long enough to come to tempera-
ture equilibrium with the surroundings. Then measure the tem-
perature of the air and the pressure of the refrigerant and compare
it to the following table:

Before measuring the pressures, use the method above to check the air
flow and then consult the table and match the liquid pressure to that air
flow.
