10. Turn ON power and verify that operation has been restored.

Electric Reheat with Modulating SCR Control (Special Option)

The electric reheat is an open coil type with a frame constructed of galvanized steel. Reheat is installed on the air
discharge side of the cooling coil. The reheat helps maintain room dry bulb conditions when the system calls for
dehumidification. The reheat section includes primary and may include secondary safety switches to protect the
system and unit from overheating. The electric reheat is paired with a solid-state modulating SCR controller for fast
and infinitely variable proportional control to precisely control room setpoint and extend heater life. The SCR
controller shall come with solid state relays, a status LED and a heatsink.
Reheating elements do not normally require maintenance. However, they may accumulate a film of dust or dirt
when unused for extended periods of time. When energized, the burning debris can create smoke or an unpleasant
odor. To help avoid a problem, periodic cleaning is recommended.

7.22.1 Electric Reheat Element Checklist

1. Check wire connections (inside reheat box).
2. Check reheat wires for wear or damage. Repair as needed.
3. Check for any physical damage on the heating element. Repair as needed.
4. Periodic Cleaning:
a. Turn OFF power all electric power sources to the unit.
b. Use lock-out tag-out protection.
c. Use a small portable vacuum cleaner to remove any dust or debris from the reheat elements.
d. Turn ON power.

Run or Start Capacitor Replacement

The run or start capacitor for a permanent-split capacitor motor is an important electric device that can lead to
serious problems for the system if not operating properly. It is one of the most frequent causes for malfunction of
the motor or the compressor. The actual replacement procedure is not very difficult to perform but requires careful
attention and good manual skills.
1. Turn OFF all remote electric power source to unit before maintenance or servicing.
2. Use lock-out tag-out protection.
3. Remove all fan motor and compressor fuses for safety reasons. Remember to replace after finish with
change out.
4. Time is required for the capacitor charge to dissipate. This may take approximately 30 seconds for the
charge to dissipate. Be careful not to touch any electrified parts.
