a. Disconnect the reheat wire harness from the bottom of the contactor in the electric box.
b. Unplug the low-voltage quick connect for the reheat safety wires.
c. Pull the conduit and wires into the unit’s blower and coil assembly section.
11. Humidifier—Optional Component
a. Disconnect the humidifier wire harness from the bottom of the contactor in the electric
box.
b. For infrared humidifiers: Remove the quick-connect plugs from the following low-voltage
connections: 35-5 and 35-6 (safety under pan), 35-3 and 35-4 (humidifier make-up valve),
and 8-5 and 8-7 (high water alarm).
c. Disconnect 35-3 and 35-4 from the control board.
d. Pull the conduit and wires into the unit’s blower and coil assembly section.
12. Condensate Pump—Optional Component
a. Disconnect the condensate pump’s high-voltage wiring harness.
b. Remove the low-volt wires from terminal strips #24 and #55.
c. Pull the conduit and wires into the unit’s blower and coil assembly section.
13. Disconnect the air sail switch wires and pull them into the electric box.
14. Smoke Detector—Optional Component
a. Remove the smoke detector cover.
b. Remove the plug connector from the smoke detector and pull it into electric box.
c. Remove the wires from terminal strips #91, 92, 93 and route them into the smoke detector
box.
d. Remove the sensing tube from top of the smoke detector.
The wand and tube will remain attached to filter and electric-box assembly.
15. Close the electric-box cover and the accent panel.
16. Remove the pull bar that supports the accent panel from the left end of unit, otherwise it will
fall out when the compressor section is removed.
17. Evacuate and recover all refrigerant from the DSE.
Air-cooled units are shipped with a nitrogen holding charge.
NOTICE
Risk of compressor oil contamination with moisture. Can cause equipment damage.
We recommend front-seating the compressor service valves. Front-seating the valves keeps
the nitrogen or refrigerant charge in the compressor and prevents moisture from
contaminating the compressor oil.
18. Cut the insulation and pull it back from the piping.
19. Cut the refrigerant piping with a tubing cutter; if there is no Schrader fitting, let the nitrogen
bleed out before cutting all the way through the pipe.
NOTE: We do not recommend un-sweating refrigerant connections.
20. Immediately cap and seal all piping that has been cut, including the suction and liquid lines.
