1. Plan installation so that ceiling penetration is located within ceiling tiles
or panels without necessitating cuts in any ceiling suspension main
runners or cross tees. If required, a maximum of one runner or cross
tee may be cut to accommodate desired damper location. Cut ends must
be supported by a minimum 12 steel wire gauge (3mm) vertical hanger
wire.
2. Position radiation damper on the inlet side of the fan so that the arrow in
the damper will point UP in the finished installation. Attach the damper
to the fan using #8 (M4) sheet metal screws (provided). There must be a
minimum of two connections on each of two opposite sides. Care must
be taken to ensure that the fasteners do not interfere with the closing of
the damper curtain. For best results, use mounting holes provided. Use
of a plastic grille requires that a minimum 5/8” (16mm) wide ceiling
support ange of steel (not provided) be attached to the radiation
damper around the inlet face, using #8 (M4) sheet metal screws or
1/4” (6mm) diameter bolts with nuts. There must be a minimum of two
connections on each of the four sides. Care must be taken to ensure that
the fasteners do not interfere with the closing of the damper curtain.
3. Mount fan/damper assembly to the deck or ceiling structure above or
adjacent to the assembly. If the assembly is hung from the structure
above, a minimum 12 steel wire gauge (3mm) hanger wire must be
used. There must be a minimum of two wires on each of two opposite
sides. If the assembly is directly mounted to the adjacent structure, use
#8 (M4) sheet metal screws or 1/4” (6mm) diameter bolts with nuts to

mechanically fasten it to the structure. Position fan/damper assembly
so that the inlet face of the radiation damper is flush with the finished
surface of the ceiling. Ceiling opening must be no larger than the inlet
opening of the damper.
4. Attach the grille supplied with the fan over the inlet face of the radiation
damper using #8 (M4) sheet metal screws (provided). There must be a
minimum of one screw on each of two opposite sides. For best results,
use mounting holes provided.
