Specifications subject to change without notice.
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 refrigerant is recovered. 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.
PERSONAL INJURY HAZARD
Failure to follow this caution could result in personal
injury.
Use of torch may cause oil to catch fire, resulting in
personal injury or death. To remove components use
tubing cutter only.
CAUTION
!
4. Disconnect liquid and vapor lines from indoor coil. Use a
tubing cutter to cut the lines.
5. Remove coil access 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.
9. Rotate columns 90°, pull away from coil, and remove
columns from assembly.
10.Remove two screws securing coil to condensate pan. (See
Figure 26)
11. Remove coil from condensate pan.
12.Attach new painted Top Seal to new coil using brass
colored screws included with packaging. (See Figure 26)
13.Remove screw at bottom of coil extension and reuse to
attached Coil Baffle in same location. Long side of baffle
toward pan. (See Figure 26)
14.Install new coil into condensate pan using two original
screws and two support columns.
15.Install new coil pan assembly into unit and secure with one
screw previously removed from unit casing.
16.Reinstall coil access panel.
17.Reconnect liquid and vapor refrigerant lines and
condensate drain line. Install new filter drier(s).
NOTE: If a torch is used to unbraze the line set, protect the
fitting panel with a wet cloth or braze shield as necessary.
18.Evacuate line set and indoor coil to 500 microns, back seat
(open) liquid and vapor service valves.
19.Turn on electrical supplies to indoor and outdoor units.
20.Check system refrigerant charge and operation. See Split−
System Residential Air Conditioners and Heat Pump
Service Manuals for further information.
