Installation guide

A. Upflow Installation
If return air is to be dueled through a floor, sc'l unit on flOOl over opening and use 1/8- to I/d-in thick fireproof resilient gasket between duct, unit,
and floor
Side return is a field option on slope coil models ("ut opening per dimensions (See Pig. 2) A fleld-seppbed botlom closure is required
B. Downflow Installation
I11this applicaflon, field conversion of tile evaporator is required using accessoly do_snflow kit along with ari accessory base kit Use fireproof
resilient gasket, 1/8- to l/4-in thick, between duct, unit, and floor.
NOTE: IZ_ convert ulgts for downflow epplicaflons, refer to Installation lnslruc_ions supplied with kit fol proper installation. FOl slope _ln coils,
use kit Part No KFADC0201SLP For A Pan coils use kit Par_ No KFADC0401 ACE Use fireproof resilient gasket, 1/8- m l/4-in thick, between
duct, unit, and floor
NOTE: Gasket kit number KFAHD01OISLP is also required for all downflow appbeations to maintain low air leak/low sweat performance.
CAUTION: The conversion of the fan coil to downflow requires special procedures for the condensate drains on both
A-coil and Slope units. The vertical drains have an overflow hole between the primary and secondary drain holes. This hole
is plugged for all applications except downflow, but must be used for downflow. During the conversion process, remove the
plastic cap covering the vertical drains only and discard. Remove the plug from the overflow hote and discard. At completion
of the downfiow installation, caulk around the vertical pan fitting to door joint to retain the low air leak performance of the
unit. Failure to follow this CAUTION coutd result in minor personal injury or product and property damage.
C. Horizontal Installation
Units must not be installed with access panels Pacing up or down All units are factory built for horizontad left installaflon. (See Fig 3 and 8) When
suspending unit from ceiling, dimples in c_sing indicate suitable locagon of screws for mounting metM support straps. (gee Fig 3)
CAUTION: For optimum condensate drainage performance in horizontal installations, unit should be leveled along its
length and width. Failure to follow this CAUTION could result in minor personal injury or product and property damage.
NOTE: Modular units can be disassemhled and componems moved separately to installation area fol reassemhly fhis process accommodates
small scuttle holes and limiting entrances to installation sites. (gee Pig 4)
