MOUNTING
The Universal Mounting Bracket System with multiple mounting points aids the
installation using industry standard materials like threaded rod and plumbers strap.
The CDB8 Unique Housing design allows for the removal of the all drive compo-
nents without the need to remove the housing from the duct connections. In addi-
tion, the electrical box connection point can be easily positioned every 45 degrees
around the motor axis to aid in installation. Motor can be positioned in any orienta-
tion from horizontal to vertical shaft down Important: motor must not
be
mounted with the Shaft Up.
HORIZONTAL MOUNTING WITH IEK8 IN-LINE ELBOW KIT
When mounting for a horizontal application, the IEK8 8” In-Line Elbow kit allows
the CDB8 to be installed In-line, maintaining a straight line exhaust duct. Replaces
42” section of straight duct. It Includes (2) 8” diameter sweep elbows, (1) 12” length
and (1) 4” length of 8” diameter duct. Use tapered transitions prior to and after
elbows if duct size of manifold is larger. DO NOT use sheet metal screws to join
sections. Aluminum duct tape is preferred. Follow all local codes and use suitable
methods for supporting CDB8 and all attached duct, (See Figure A).
VERTICAL MOUNTING
The unique housing design of CDB8 with the inlet collar and outlet collar on the
same plane allows the CDB8 to be used as a 90 degree elbow. Use tapered transi-
tions if duct size of manifold is larger. DO NOT use sheet metal screws to join sec-
tions. Aluminum duct tape is preferred. Follow all local codes and use suitable
methods for supporting CDB8 and all attached duct, (See Figure B).
WIRING
The CDB8 must be wired by a qualified installer (an individual properly licensed and/or trained) in accordance with these instruc-
tions and in accordance with all local codes or in their absence, with the current editions of NFPA 70, National Electrical Code in
the U.S. or CSA C22.1-12 Canadian Electrical Code in Canada.
All wiring from the CDB8 to the Dryer Exhaust Fan junction box must be appropriate Class 1 wiring as follows: installed in rigid
metal conduit, intermediate metal conduit, rigid non-metallic conduit, electrical metallic tubing, Type MI Cable, Type MC Cable, or
be otherwise suitably protected from physical damage.
NOTE: The wiring diagrams shown in this manual do not include the use of the COP2DB Constant Pressure Controller. See
COP2DB manual for wiring diagram.
