The installers should balance the air distribution system to ensure proper quiet air-
low to all rooms in the home. This ensures a comfortable living space.

These simple mathematical formulas can be used to determine the CFM in a resi-
dential or light commercial system.

Electric resistance heaters can use

CFM =

volts x amps x 3.414

1.08 x temp rise

Gas furnaces can use

CFM =

BTUH

∆

T x 1.08

An air velocity meter or airflow hood can give a more accurate reading of the sys-
tem CFM’s.

CHECKING REFRIGERANT CHARGE

Charge for all systems should be checked against the Charging Chart inside the
access panel cover. Before using the chart, the indoor conditions must be within
2°F of desired comfort conditions and system must be run until operating conditions
stabilize (15 min. to 30 min.)

IMPORTANT:

Do not operate the compressor without charge in system.

Addition of R-410A will raise pressures (vapor, liquid and discharge) and lower
vapor temperature.

If adding R-410A raises both vapor pressure and temperature, the unit is over-
charged.

IMPORTANT:

Use industry-approved charging methods to ensure proper system

charge.

CHARGING BY LIQUID PRESSURE

Liquid pressure method is used for charging systems in the cooling mode when an
expansion valve is used on the evaporator. The service port on the liquid service
valve (small valve) is used for this purpose.

Read and record the outdoor ambient temperature entering the condensing unit,
and the liquid line pressure at the service valve (the small valve). Locate the charg-
ing chart attached to the unit. The correct liquid line pressure will by found by find-
ing the intersection of the unit model size and the outdoor ambient temperature.
Adjust the liquid line pressure but either adding refrigerant to raise pressure or
removing refrigerant to lower pressure.

CHARGING UNITS WITH R-410A REFRIGERANT

Checking the charge, or charging units using R-410A refrigerant, differs from those
with R-22. The following procedures apply to units with R-410A refrigerant. These
procedures require outdoor ambient temperature, liquid line pressure and indoor
wet bulb temperature be used.

IMPORTANT:

ONLY ADD LIQUID REFRIGERANT CHARGE INTO THE SUCTION

LINE WITH R-410A UNITS. USE A COMMERCIAL METERING DEVICE TO ADD
CHARGE INTO THE SUCTION LINE WITHOUT DAMAGE TO THE COMPRES-
SOR.

1. Read and record the outdoor ambient temperature entering the condensing

unit.

2. Read and record the liquid line pressure at the small service valve.

!

CAUTION

THE TOP OF THE SCROLL COMPRESSOR SHELL IS HOT. TOUCHING THE
COMPRESSOR TOP MAY RESULT IN SERIOUS PERSONAL INJURY.
