Manual 2100-324Page 14FAN BLADE SETTINGSShown in Figure 9 are the correct fan blade settingdimensions for proper air delivery across the outdoor coil.Any service work requiring removal or adjustment in thefan and/or motor area will require that the dimensionsbelow be checked and blade adjusted in or out on themotor shaft accordingly.FIGURE 9FAN BLADE SETTING DIMENSIONSSUCTION AND DISCHARGE TUBEBRAZINGCompliant Scroll compressors have copper plated steelsuction and discharge tubes. These tubes are far morerugged and less prone to leaks than copper tubes used onother compressors. Due to different thermal properties ofsteel and copper, brazing procedures may have to bechanged from those commonly used.• To disconnect: heat joint Areas 2 and 3 slowly anduniformly until braze material softens and the tube canbe pulled out of suction fitting. (See Figure 10.)• To connect:– Recommended brazing materials: silfos withminimum 5% silver or silver braze material withflux.– Reinsert tube into fitting.– Heat tube uniformly in Area 1 moving slowly toArea 2. When joint reaches brazing temperature,apply brazing material. (See Figure 10.)– Heat joint uniformly around the circumference toflow braze material completely around the joint.– Slowly move torch into Area 3 to draw brazematerial into joint. (See Figure 10.)– Do not overheat joint.ledoM AnoisnemiD3A2411P1A8411P1A0601P"57.1"57.1"57.1TABLE 9The above suction line temperatures are based upon80°F dry bulb/67°F wet bulb (50% RH) temperature andrated airflow across the evaporator during cooling cycle.ledoMdetaRwolfriAFeergeD59DOerutarepmeTFeergeD28DOerutarepmeT3A2411P1A8411P1A0610P00410551007195-7575-5594-7406-8516-9565-45SERVICE AND TROUBLESHOOTINGSERVICE HINTS1. Caution homeowner to maintain clean air filters at alltimes. Also, not to needlessly close off supply andreturn air registers. This reduces air flow through thesystem which shortens equipment service life as wellas increasing operating costs.2. Check all power fuses or circuit breakers to be surethat they are the correct rating.3. Periodic cleaning of the outdoor coil to permit full andunrestricted airflow circulation is essential.PRESSURE SERVICE PORTSHigh and low pressure service ports are installed on allunits so that the system operating pressures can beobserved. Pressure tables can be found in Table 10 in thismanual covering all models on cooling cycle. It isimperative to match the correct pressure table to the unitby model number.REFRIGERANT CHARGEThe correct system R-22 charge is shown on the unit ratingplate. Optimum unit performance will occur with arefrigerant charge resulting in a suction line temperature(6” from compressor) as shown in Table 9.
