Instruction manual

1. Recover system refrigerant.
a. Attach gage/manifold set to service valves.
b. Start unit in cooling mode.
c. Front seat (close) liquid line service valve.
d. Operate unit until vapor pressure reaches 5 psig (35kPa).
e. Turn off electrical supply to outdoor unit.
f. Front seat (close) vapor service valve.
g. Recover any remaining refrigerant.
NOTE: All condenser coils hold only a factory-supplied amount of refrigerant. Excess refrigerant, such as in long-line applications, may cause
compressor internal pressure relief valve to open (indicated by sudden rise in vapor pressure) before vapor pressure reaches 5 psig (35kPa). If this
occurs, turn off electrical supply to outdoor unit immediately, front seat (close) vapor service valve, and recover any remaining refrigerant.
2. Turn off electrical supply to indoor unit.
3. Disconnect condensate drain line.
WARNING: Do not use torch to remove components. Oil may catch fire causing personal injury or death. Use tubing
cutter.
4. Disconnect liquid and vapor lines from indoor coil (use a tubing cutter to cut the lines).
5. Remove coil access blower and fitting panels.
6. Remove 1 screw securing coil to unit casing.
7. Remove coil/pan assembly from unit.
8. Place assembly on a flat surface. Remove 2 screws securing coil support columns to pan. (See Fig. 2.)
9. Rotate columns 90°, pull away from coil, and remove columns from assembly.
10. Remove remaining 2 screws securing coil to condensate pan.
11. Remove coil from condensate pan.
12. Discard old drain pan and supports
13. Remove kit from carton.
14. Snap metal pan support (ski) into bottom of drain pan.
15. Slide coil into pan assemble.
16. Snap in supports.
17. Secure coil to pan with 2 sheet metal screws.
18. Re-install coil/pan assembly into unit casing.
19. Secure with 1 screw into unit casing.
20. Install new fitting panel.
21. Replace coil access blower panels.
22. Connect drains.
a. Cap openings must be removed.
b. Use a knife to start the opening near the tab and, using pliers, pull the tab to remove the disk.
c. Clean the edge of the opening if necessary and install the condensate line.
d. Caulk around the lines where they exit the fitting to retain the low leak rating of the unit.
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 overlow 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. Failure to follow this CAUTION could result in minor personal injury or product and property damage.
