Installation
WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power cannot be inadvertently energized. For variable
frequency drives or other energy storing components provided by Trane or others, refer to the
appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors.
Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect
power and discharge capacitors before servicing could result in death or serious injury.
WARNING
Fire Hazard!
The BAYHTRA, BAYHTRB, BAYHTRD, BAYHTRU, and BAYHTRW heater kits require a one inch
clearance from the supply ductwork to any combustible materials. Failure to allow proper
clearance could result in combustible materials catching on fire which could result in death,
serious injury, or property damage.
1.
Remove heater compartment access panel and unit control box access panel. See
Figure 2
.
Note:
On downflow units with or without duct work installed or horizontal units without ductwork
installed, remove horizontal supply cover from the rear of the heater compartment.
2. Remove insulation to expose perimeter of removable panel in the vestibule panel. See
Figure 2
.
3. Clip or cut the retaining tabs around the perimeter of the removable panel.
4. Remove the panel.
5. Check the opening in the vestibule panel. Remove any metal burrs or slivers that could damage
or pinch the heater elements resulting in a short circuit when elements are installed in the
opening.
Note:
Locator tabs on the vestibule panel support the electric heat assembly and secure the
inward edge of the electric heat accessory control panel. Slits in the insulation should allow
the tabs to protrude through the insulation and be visible. However, it may be necessary to
work the insulation back from the tabs and slightly bend the tabs outward if difficulty is
encountered engaging the electric heater panel or the electric heat accessory control panel.
