Face and Bypass Damper Add-on Filter
Section
HAB units equipped with face and bypass damper s may have
the add-on filter section specified as an option. Add-on filter
sections ship separately and are field installed. Figure 14
shows the add-on filter section placement. Use the following
steps as guidelines for filter section installation.
1. Slip add-on filter section over the face and bypass
damper front.
2. Secure filter section to damper using field-supplied short
sheet-metal screws inserted into factory-punched holes.
3. Verify screws do not hinder damper operation.

− Not all installations require a starter (some
motors utilize a contactor).
• Ensure all filters are installed. Perform filter check
with all doors and panels in place.
• Never assume the voltage and phase on the unit
nameplate is the same was the motor wired.
• Check alignment of the sheaves and ensure the
setscrews are tight.
• Check for proper rotation of the blower pulley.
• Check motor phase and rotation.
− Exchanging two of the three leads at the unit
junction box.
− Exchanging leads inside the motor junction box can
reverse the rotation of single-phase motors. Refer to
the motor nameplate.
• Check amperage draw of the motor. The
amperage draw should not exceed the nameplate
amps shown on the motor serial plate.
