Installation Instructions

Downflow Kit for EBP, EBX, EBW and EBV Series

These instructions must be read and understood completely before attempting installation.

Fire Hazard

The purpose of the subbase assembly is to maintain

a1" clearance to combustible materials.

Attach supply duct to inner flange of subbase.

Failure to do so can result in fire, bodily injury or

death.

The downfiow conversion for slope units

following items:

Coil bracket (1)

Coil baffle (1)

Screws (2)

Foam gasket (1)

requires the

WARNING: Before beginning any installation or

modification, be sure the main electrical disconnect

switch is in the OFF position. Tag the disconnect

switch with a suitable warning label. Electrical shock

can cause personal injury or death.

INTRODUCTION

Fan coils are factory-shipped for upfiow or horizontal-left

applications. This instruction covers the installation of

downfiow conversion kit on models EBP, EBX, EBW and

EBV fan coils. The kit provides a means of installing fan coils

in a downfiow position.

DESCRIPTION AND USAGE

The downfiow conversion kits are available for use on slope

and A-coil versions of previously mentioned fan coils. When

installed, the kit will provide proper condensate water

drainage, as well as a means of supporting the coil. See unit

Installation Instructions for proper kit part numbers.

The downfiow conversion for A-coil units requires the

following items:

Coil bracket (2)

Support strap (1)

Drainage hole plugs (2)

Angle (2)

Screws (4)

Air seal (1)

NOTE: The fan coils are factory shipped for upfiow or

horizontal-left applications. Installation of the Downfiow

Conversion Kit should be complete before the fan coil unit

is positioned to ensure side access required for installation

of the coil brackets.

NOTE: If unit has electric heat with a circuit breaker, refer

to electric heater Installation Instructions for repositioning of

breaker assembly.

INSTALLATION-A-COILUNITSONLY

1.Remove all panels and expose blower and coil areas.

2.Remove any shipping clips securing coil.

3.Remove complete coil/drain pan assembly.

4.Remove and discard horizontal drain pan from coil

assembly.

&Drill four 1/4-in. holes (2 on each side) in fan coil casing

at dimples provided. (See Fig. 1.)

6.Secure coil brackets (provided in kit) to casing sides. (See

Fig. 1.)

7.Install support strap (provided in kit) across front of unit as

follows:

a.Position flange on each end of strap between coil

bracket and casing insulation. (See Fig. 1.)

b.Secure support strap ends to coil brackets. (See Fig. 1.)

&Remove and discard 4 clips (on corners of coil) securing

coil assembly to rails for upflow applications.

9.Remove and discard factory-shipped air seal and drain

tube assembly. Install 1-piece sheet metal air seal

assembly provided with kit.

1&Tilt coil assembly back and slide angles (provided in kit)

over each inside wall of condensate pan. Pop- riveted flange

of angles should extend toward coil. (See Fig. 2.)

11.With fan coil in downflow position, slide coil assembly into

unit. (See Fig. 3.)

12.Reinstall all panels. Align holes in panels with tubing and

condensate connections. Casing was designed to allow 180

degree rotation of coil access panel and fitting panel.

1&Install 2 plugs that have been provided onto doors to seal

unit.

INSTALLATION- SLOPE COIL UNITS ONLY

1.Remove all panels and expose blower and coil areas.

2. Remove screw securing coil assembly to right side flange.

Remove complete coil/drain pan assembly.

&Drill two 1/4-in. holes in right side of casing at dimples

provided (unit in upflow position).

4.Place fan coil unit in downflow position.

&Secure coil bracket to left side of casing with 2 screws

provided. (See Fig. 4.)

&Remove top coil bracket from coil (2 screws).

b.Align holes in gasket with holes in top coil bracket.

c.Remove only half of the backing from the gasket.

&Apply exposed half of foam gasket to under side of top

coil bracket. (See Fig. 5.)

e.Remove remaining piece of backing from gasket and

press gasket into place.

f.Replace top bracket onto coil. The 2 screws must engage

the lanced holes.

&Install remaining coil baffle at coil end opposite the coil

headers. (See Fig. 6.)

a.Slide the longer flange of baffle between tube sheet and

end of condensate pan. Be sure notch in baffle is fully

seated below notch in tube sheet.

NOTE: The TXV sensing bulb must be insulated on slope

coils in horizontal right and downflow applications. Failure to

insulate bulb will result in performance loss.

7.Insulate TXV sensing bulb with cork tape or other

permanent insulating material.

&Invert coil assembly and slide it into unit with drain pan to

left side of fan coil. Secure coil assembly with screws. (See

Fig. 3.)

&Reinstall fitting panel, blower panel, and coil access panel.

Align holes in panels with tubing and condensate

connections.
