INSTALLATION / A-COIL HORIZONTAL LEFT
See Fig. 3
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.
19. Resecure coil with retaining clips.
20. Install fitting panel.
21. Replace coil access blower panels and filter door.
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.
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, filter and
filter door.
6. Remove coil retaining clips.
7. Remove coil/pan assembly from unit.
8. Place assembly on a flat surface in the vertical position
facing liquid and suction lines.
13. Remove kit from carton.
14. Remove existing cindensate trough from A-coil and
install on opposite side of A-coil
14. Add drain tube to left drainport on airsplitter
15. Set coil into pan assembley with pan drains facing out.
18. Re-install coil/pan assembly into unit casing.
