135. Open the filter clips which are located underneath thehood top. Insert the aluminum filter into the bottomfilter rack (hood divider). Push the filter into positionpast the open filter clips. Close the filter clips to lockthe filter into place. See Fig. 14.DIVIDERBAROMETRICRELIEFCLEANABLEALUMINUMFILTER FILTERHOODFILTERCLIPOUTSIDEAIRC08634Fig. 14 -- Economizer Filter Installation6. Caulk the ends of the joint between the unit top paneland the hood top.7. Replace the filter access panel.Step 9 — Install External Condensate Trap andLineThe unit has one 19 mm (3 / 4 -in.) condensate drainconnection on the end of the condensate pan and analternate connection on the bottom. See Fig. 15. Unitairflow configuration does not determine which drainconnection to use. Either drain connection can be usedwith vertical or horizontal applications.When using the standard side drain connection, ensure thered plug in the alternate bottom connection is tight. Dothis before setting the unit in place. The red drain pan canbe tightened with a 12.7 mm (1 / 2 --in.) square socket driveextension.To use the alternate bottom drain connection, remove thered drain plug from the bottom connection (use a 12 mm[1 / 2 --in.] square socket drive extension) and install it in theside drain connection.DRAIN(FACTORY-INSTALLED)PLUGCONDENSATE PAN (SIDE VIEW)STANDARDSIDE DRAINALTERNATEBOTTOM DRAINC08021Fig. 15 -- Condensate Drain Pan (Side View)The piping for the condensate drain and external trap canbe completed after the unit is in place. See Fig. 16.NOTE: Trap should be deep enough to offset maximum unit staticdifference. A 102 mm (4 in.) trap is recommended.MINIMUM PITCH25 mm (1 in.) PER3m (10 ft.)

Install a trap at least 102 mm (4-in.) deep andprotect against freeze-up. If drain line is installeddownstream from the external trap, pitch the line awayfrom the unit at 25 mm in 3 m (1-in. per 10 ft) of run. Donot use a pipe size smaller than the unit connection of19 mm ( 3/4 -in.).Step 10 — Make Electrical ConnectionsELECTRICAL SHOCK HAZARDFailure to follow this warning could result in personalinjury or death.Do not use gas piping as an electrical ground. Unitcabinet must have an uninterrupted, unbrokenelectrical ground to minimize the possibility ofpersonal injury if an electrical fault should occur. Thisground may consist of electrical wire connected tounit ground lug in control compartment, or conduitapproved for electrical ground when installed inaccordance with local electrical codes or in absenceof local codes, it is recommended that the U.S.A.standard ANSI/NFPA 70, National Electrical Code(NEC), be followed.! WARNINGNOTE: Check all factory and field electrical connectionsfor tightness. Field--supplied wiring shall conform withthe limitations of 33_C (63_F) rise.Field power wires are connected to the unit at line--sidepressure lugs on compressor contactor C and indoor fancontactor IFC (see wiring diagram label for control boxcomponent arrangement) or at factory--installed optionnon--fused disconnect switch. Use copper conductors only.NOTE: Make field power connections directly to lineconnection pressure lugs only.50TC
