evaporator coil, the intake air routing should be modi- fied as shown in figure 28.

2 − Use a #7 sheet metal screw to secure the intake pipe to the connector, if desired. A pilot indentation is provided in the slip connector to assist in locating and starting the fas- tener.

3 − Glue the provided 2" ABS plug into the unused ABS air intake connector on the opposite side of the cabinet with ABS or all purpose solvent cement.

1 − Use field−provided materials and the factory−provided air intake screen to route the intake piping as shown in figures 27 and 28. Maintain a minimum clearance of 3" (76mm) around the air intake opening. The air intake opening (with the protective screen) should always be directed either downward or straight out. Use 2" pipe and fittings only and make sure that the air intake does not extend more than 6" beyond the G61MP cabinet. The air intake connector must not be located near the floor. To avoid this complication in downflow applications which do not include a downflow
