DOWNFLOW INSTALLATION

In this application, field conversion of the evaporator is required using

accessory downflow kit along with an accessory base kit. Use fireproof

resilient gasket, 1/8 to 1/4-in (3 to 6 mm) thick, between duct, unit, and

floor.

NOTE: 

To convert units for downflow applications, refer to Installation

Instructions supplied with kit for proper installation. For slope fan coils,

use  kit  Part  No.  KFADC0201SLP.  For  A-coils,  use  kit  Part  No.

KFADC0401ACL. Use fireproof resilient gasket, 1/8  to 1/4-in (3 to 6

mm) thick, between duct, unit, and floor.

NOTE: 

Gasket  kit  number  KFAHD0101SLP  is  also  required  for  all

downflow applications to maintain low air leak/low sweat performance.

HORIZONTAL INSTALLATION

Units must not be installed with access panels facing up or down. All

other  units  are  factory  built  for  horizontal  left  installation  (

Fig. 2

  and

Fig. 3

). When suspending unit from ceiling, dimples in casing indicate

suitable location of screws for mounting metal support straps (

Fig. 2

).

For horizontal applications having high return static  and humid return

air, the Water Management Kit, KFAHC0125AAA, may need to be used

to assist in water management.

CAUTION

!

PRODUCT OR PROPERTY DAMAGE HAZARD

Failure to follow this warning caution may result in product or property

damage. 

The conversion of the fan coil to downflow requires special procedures

for  the  condensate  drains  on  both A-coil  and  Slope-coil  units.  The

vertical  drains  have  an  overflow  hole  between  the  primary  and

secondary drain holes. This hole is plugged for all applications except

downflow, and must be used for downflow.  During conversion process,

remove plastic cap covering vertical drains only and discard. Remove

plug  from  overflow  hole  and  discard.  At  completion  of  downflow

installation, caulk around vertical pan fitting to door joint to retain low

air leak performance of the unit.
