Installation Instructions
Horizontal Drain Pan
for EBP, EBX, EBW and EBV Series Fan Coils
These instructions must be read and understood completely before attempting installation.
All units must have the horizontal drain pan kit installed for
either left or right hand applications.
CAUTION
A field-fabricated auxiliary drain pan, with a sepa-
rate drain is REQUIRED for all installations over a
finished living space or in any area that may be
damaged by overflow from the main drain pan. In
some localities, local codes require an auxiliary
drain pan for ANY horizontal installation.
Refer to Installation Manual for electric furnace or
fan coil for additional information.

INSTALLATION / SLOPE COILS
If it is determined that the system does not have
leaks, and the refrigerant is not contaminated,
proceed as follows:
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 on Pg. 2)
9. Rotate columns 90 degrees, 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. Reconnect liquid and vapor refrigerant lines and
condensate drain line. Install filter drier(s) if necessary.
NOTE: tf a torch is used to unbraze the line set, protect the
fitting panel with a wet cloth or braze shield as necessary.
23. Evacuate line set and indoor coil.
24. Back seat (open) liquid and vapor service valves.
25. Turn on electrical supplies to indoor and outdoor units.
26. Check system refrigerant charge and operation.
