CONDENSATE DRAIN HOLE

Fig. 7 Ð Condensate Connection Details

Fig. 8A Ð Condensate Trap (Using Tubing)

Fig. 8B Ð Condensate Trap (Using PVC Piping)

If the installation requires draining the condensate water away from the unit, install a ®eld-supplied 2-in. trap using 3¤4-in. OD tubing or piping to ensure proper drainage. See Fig. 8A and 8B. Make sure that the outlet of the trap is at least one in. lower than the unit drain pan condensate con- nection to prevent the pan from over¯owing. Connect a drain tube using a minimum of 3¤4-in. PVC, 3¤4-in. CPVC, or 3¤4-in. copper pipe (all ®eld-supplied). Do not undersize the tube. Pitch the drain tube downward at a slope of at least 1 inch in every 10 ft of horizontal run. Be sure to check the drain tube for leaks. Prime trap at the beginning of cooling season start-up. Allowable glues for condensate trap connection are: Stand- ard ABS, CPVC, or PVC cement.

B. Field-Duct Connections

NOTE: The design and installation of the duct system must be in accordance with the standards of NFPA for the instal- lation of nonresidence-type air conditioning and ventilating systems, NFPA 90A or residence-type, NFPA 90B, and/or local codes and ordinances.

Units have duct ¯anges on the supply- and return-air open- ings on the side of the unit. See Fig. 2-4 for connection sizes and locations.
