Fig. 7 -- A--Coil in Horizontal--Right Application
E. Horizontal Right Conversion of Units With A--Coil
To convert units for horizontal right installations:
1. Remove blower and coil access panels. (See Fig. 6.)
2. Remove metal clip securing fitting panel to condensate pan.
Remove fitting panel.
3. Remove 2 snap--in clips securing A--coil in unit.
4. Slide coil and pan assembly out of unit.
5. Remove horizontal drain pan support bracket from coil sup-
port rail on left side of unit and reinstall on coil support rail
on right side of unit.
6. Convert air--seal assembly for horizontal right.
a. Remove air--seal assembly from coil by removing 4
screws. (See Fig. 6.)
b. Remove air splitter (B) from coil seal assembly by re-
moving 3 screws. (See Fig. 6--factory--shipped inset.)
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 ap-
plication.
e. Remove condensate troughs (C) and install on opposite
tube sheets.
f. Install hose onto plastic spout.
7. Install horizontal pan on right side of coil assembly.
8. Slide coil assembly into casing. Be sure coil bracket on each
corner of vertical pan engages coil support rails.
9. Reinstall 2 snap--in clips to correctly position and secure
coil assembly in unit. Be sure clip with large offset is used
on right side of unit to secure horizontal pan.
10. Remove two oval fitting caps from left side of the coil, ac-
cess panel, and fitting panel.
11. Remove insulation knockouts on right side of coil access
panel
12. Remove 2 oval coil access panel plugs and reinstall into
holes on left side of coil access panel and fitting panel.
13. Install condensate pan fitting caps (from Step 10) in the
right side of the coil door making sure that the cap snaps
and seats cleanly on the back side of the coil door. Make
sure no insulation interferes with seating of the cap.
14. Reinstall access and fitting panels, aligning holes with
tubing connections and condensate pan connections. Be
sure to reinstall metal clip between fitting panel and vertical
condensate pan.
Make sure liquid and suction tube grommets are in place to prevent
air leaks and cabinet sweating.
F. Downflow Installations
UNIT OR PROPERTY DAMAGE HAZARD
Failure to follow this 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
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 hole and discard. At completion of the
downflow installation, caulk around the vertical pan fitting to
door joint to retain the low air leak performance of the unit.
CAUTION
!
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. (3.2 to 6.4mm) 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 fan
coils use kit Part No. KFADC0401ACL. Use fireproof resilient
