Installing PCO Cabinet
The PCO cabinet may either be installed on a level
installation deck or platform adjacent to the air handler or it
may be suspended from the rafters using metal strapping.
If straps are used, take care when attaching straps to the
PCO cabinet. Ensure fasteners do not interfere with
internal components of the PCO cabinet. Filter, PureAir
Insert and control box must be able to slide freely into the
cabinet.

and water solution to wash all new duct and transition
surfaces.
2. Use the air flow directional label on the inside of the
PCO cabinet to orient the PCO unit. Properly position
the PCO cabinet next to the return air opening of the
air handling unit. Use sheet metal screws (1”
maximum length), rivets or other appropriate
fasteners to secure PCO cabinet to the return air side
of the air handling unit.
3. Use sheet metal screws (1” maximum length) to fasten
the return air duct to the other side of the PCO cabinet.
4. Use aluminum foil tape or water-based mastic to seal
all joints between the PCO cabinet, air handler and
duct.
5. In high humidity applications, wrap PCO cabinet with
2” foil-faced insulation (foil on the outside) to prevent
condensation.
