TABLE 8
The above suction line temperatures are based upon 80°F dry
bulb/67°F wet bulb (50% RH) temperature and rated airflow
across the evaporator during cooling cycle.
FAN BLADE SETTINGS
Shown in Figure 9 are the correct fan blade setting
dimensions for proper air delivery across the outdoor coil.
Any service work requiring removal or adjustment in the fan
and/or motor area will require that the dimensions below be
checked and blade adjusted in or out on the motor shaft
accordingly.

SUCTION AND DISCHARGE TUBE
BRAZING
Compliant Scroll compressors have copper plated steel
suction and discharge tubes. These tubes are far more
rugged and less prone to leaks than copper tubes used on
other compressors. Due to different thermal properties of
steel and copper, brazing procedures may have to be
changed from those commonly used.
• To disconnect: heat joint Areas 2 and 3 slowly and
uniformly until braze material softens and the tube can
be pulled out of suction fitting. (See Figure 10.)
• To connect:
– Recommended brazing materials: silfos with
minimum 5% silver or silver braze material with
flux.
– Reinsert tube into fitting.
– Heat tube uniformly in Area 1 moving slowly to
Area 2. When joint reaches brazing temperature,
apply brazing material. (See Figure 10.)
– Heat joint uniformly around the circumference to
flow braze material completely around the joint.
– Slowly move torch into Area 3 to draw braze
material into joint. (See Figure 10.)
– Do not overheat joint.

SERVICE AND TROUBLESHOOTING
SERVICE HINTS
1. Caution homeowner to maintain clean air filters at all
times. Also, not to needlessly close off supply and
return air registers. This reduces air flow through the
system which shortens equipment service life as well as
increasing operating costs.
2. Check all power fuses or circuit breakers to be sure that
they are the correct rating.
3. Periodic cleaning of the outdoor coil to permit full and
unrestricted airflow circulation is essential.
PRESSURE SERVICE PORTS
High and low pressure service ports are installed on all units
so that the system operating pressures can be observed.
Pressure tables can be found in Table 9 in this manual
covering all models on cooling cycle. It is imperative to
match the correct pressure table to the unit by model
number.
REFRIGERANT CHARGE
The correct system R-22 charge is shown on the unit rating
plate. Optimum unit performance will occur with a
refrigerant charge resulting in a suction line temperature
(6” from compressor) as shown in Table 8.
