2 Sweat connect units are factory chargedwith refrigerant for a matching indoor coil plus 15 feet of field indoor coils are available with a thermal expansion valvesized for the most common usage. The refrigerant charge may need tobe changed for some indoor-outdoor unit combinations, elevation differ-ences or total line lengths. Refer to Application Data covering GeneralPiping Recommendations and Refrigerant Line Length (Part Number036-61920-001).SECTION II: SAFETYThis is a safety alert symbol. When you see this symbol onlabels or in manuals, be alert to the potential for and pay particular attention to the signal words DANGER,WARNING, or CAUTION.

3 DANGER indicates an imminently hazardous situation, which, if notavoided, will result in death or serious indicates a potentially hazardous situation, which, if notavoided, could result in death or serious indicates a potentially hazardous situation, which, if notavoided may result in minor or moderate injury. It is also used toalert against unsafe practices and hazards involving only property dam-ageINSPECTIONAs soon as a unit is received, it should be inspected for possible dam-age during transit. If damage is evident, the extent of the damageshould be noted on the carrier s delivery receipt.

4 A separate request forinspection by the carrier s agent should be made in writing. See LocalDistributor for more unit should be installed in accordance with all National, State andLocal Safety Codes and the limitations listed for the indoor unit, coil, and appropriate accessoriesmust also be outdoor unit must not be installed with any duct work in the airstream. The outdoor fan is the propeller type and is not designedto operate against any additional external static INSTALLATION may create a condition where the operation ofthe product could cause personal injury or property INSTALLATION , adjustment, alteration, service or mainte-nance can cause injury or property damage.

8 Observe all limitations andclearance outdoor unit must have sufficient clearance for air entrance to thecondenser coil, air discharge, and service access. See Figure : For multiple unit installations, units must be spaced a minimumof 18 inches apart (coil face to coil face).If the unit is to be installed on a hot sun exposed roof or a black-toppedground area, the unit should be raised sufficiently above the roof orground to avoid taking the accumulated layer of hot air into the an adequate structural REPLACEMENT/RETROFITThe following steps should be performed in order to insure proper sys-tem operation and the indoor coil, if required, to an approved R-22 coil/condensing unit combination with the appropriate metering the outdoor unit is being replaced due to a compressor burnout.

9 Then INSTALLATION of a 100% activated alumina suction-line filterdrier in the suction-line is required, in addition to the factoryinstalled liquid-line drier. Operate the system for 10 hours. Monitorthe suction drier pressure drop. If the pressure drop exceeds 3psig, replace both the suction-line and liquid-line driers. After atotal of 10 hours run time where the suction-line pressure drop hasnot exceeded 3 psig, replace the liquid line drier, and remove thesuction-line drier. Never leave a suction-line drier in the systemlonger than 50 hours of run INSTALLATIONThe unit should be installed on a solid base that is 2 above grade andwill not shift or settle, causing strain on the refrigerant lines and possibleleaks.

10 Maintain the clearances shown in Figure 1 and install the unit in alevel position. The base pad should not come in contact with the foun-dation or side of the structure because sound may be transmitted to length of the refrigerant tubing between the outdoor unit and indoorcoil should be as short as possible to avoid capacity and efficiencylosses. Excessive spacing of the outdoor unit from the home can resultin the refrigerant lines being restricted by trampling or being puncturedby lawn mowers. Locate the outdoor unit away from bedroom windowsor other rooms where sound might be effects of snow or sleet accumulating on the outdoor coil canbe eliminated by placing the outdoor unit where the prevailing winddoes not blow across the unit.
