c. Remove filler plate (A) and install air splitter (B) in place of filler plate.

d. Install filler plate (A) as shown in horizontal right application.

e. Remove condensate troughs (C) and install on opposite tube sheets.

f. Install hose onto plastic spout.

9. Install horizontal pan on right side of coil assembly with plugged condensate openings to rear of assembly.

10. Slide coil assembly into casing. Be sure coil bracket on each corner engages coil support rails.

11. Remove condensate drain knockouts from right side of coil access panel.

12. Reinstall access and fitting panels, aligning holes with tubing connections and condensate pan connections.

Make sure liquid and suction tube grommets are in place to prevent air leaks and cabinet sweating.

PROCEDURE 2—AIR DUCTS

Connect the supply-air duct over the outside of the 3/4-in. flanges provided on the supply-air opening. Secure the duct to the flange, using proper

fasteners for the type of duct used, and seal the duct-to-unit joint. If return-air flanges are required, install factory-authorized accessory kit.

Use flexible connectors between ductwork and unit to prevent transmission of vibration. When electric heater is installed, use heat-resistant

material for flexible connector between ductwork and unit at discharge connection. Ductwork passing through unconditioned space must be

insulated and covered with vapor barrier.

A. Ductwork Acoustical Treatment

Metal duct systems that do not have a 90° elbow and 10 ft of main duct to first branch takeoff may require internal acoustical insulation lining.

As an alternative, fibrous ductwork may be used if constructed and installed in accordance with the latest edition of SMACNA construction

standard on fibrous glass ducts. Both acoustical lining and fibrous ductwork shall comply with National Fire Protection Association as tested by

UL Standard 181 for Class 1 air ducts.

PROCEDURE 3—ELECTRICAL CONNECTIONS

All products from the factory utilize a new printed-circuit board (PCB) which has the low voltage circuit protective fuse (5 amp) and fan motor

speed tap selection terminal (SPT). (See Fig. 6.)

When a factory-approved accessory control package has been installed, check all factory wiring per unit wiring diagram and inspect factory wiring

connections to be sure none were loosened in transit or installation. If a different control package is required, see unit rating plate.

CAUTION: If a disconnect switch is to be mounted on the unit, select a location where drill or fastener will not contact

electrical or refrigerant components.

Before proceeding with electrical connections, make certain that supply voltage, frequency, phase, and ampacity are as specified on the unit rating

plate. See unit wiring label for proper field high- and low-voltage wiring. Make all electrical connections in accordance with the NEC and any

local codes or ordinances that may apply. Use copper wire only.

The unit must have a separate branch electric circuit with a field-supplied disconnect switch located within sight from and readily accessible from

the unit.
