34. REFRIGERANT CHARGE
The correct system R-410A 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 18.
The suction line temperatures in Table 18 are based upon
80 degrees F dry bulb / 67 degree wet bulb (50% R.H.)
temperature and rated airflow across the evaporator
during cooling cycle. If charge quantity is in doubt,
reclaim and recharge to factory name plate quantity.
Total system charge for these models can be found in
Table 1.
35. FAN BLADE SETTING DIMENSIONS
Shown in Figure 21 is the correct fan blade setting
dimension for proper air delivery across the outdoor
coil.

36. LOW-NOX BURNER ASSEMBLY “N”
SUFFIX MODELS ONLY – U.S.
INSTALLATIONS ONLY
NATURAL GAS MODELS ONLY
Model numbers designated with an “N” are designed
for low NOx emissions which comply with all
California Air Quality Management District regulations
for nitrogen oxide emission levels. Refer to Figure 22
for NOx insert information.
* * IMPORTANT * *
For propane (LP) conversions the NOx
reduction screen inserts shown below must
be removed. This is accomplished by
removing the burner box assembly and
removing the NOx screens. Reassemble unit
properly before firing. Failure to remove the
NOx screens can result in improper operation
and malfunction of the burner system.
