Installation Mechanical

 WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper

lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to

disconnect power before servicing could result in death or serious injury.

Installing the Unit

Follow the procedures below to install the blower coil unit.

Horizontal Units, Model BCHC

Install horizontal units suspended from the ceiling with 3/8” threaded rods that are field provided.

There are two knockouts in each corner of the unit for installation of the threaded rods. Ensure the

ceiling opening is large enough for unit installation and maintenance requirements.

BCHC Installation Procedure

Materials needed:

• threaded rods, 3/8” (4)

• nuts (8)

• flat washers or steel plates (8)

• vibration isolator hangers or turnbuckles (4)

1. Determine the unit mounting hole dimensions. Prepare the hanger rod isolator assemblies,

which are field provided, and install them in the ceiling. Trane recommends using threaded rods

to level the unit. Consult the unit nameplate or “Dimensions and Weights,” p. 15 in t his man ual

for the unit weight. See Figure4 for proper horizontal unit installatio n.

2. Remove motor access panels and filter access panels.

3. Punch out the eight knockouts in the top and bottom panels.
