INSTALLATION

UNPACKING
PREPARATION
Upon receipt, immediately inspect the carton for damage during transit. Signs of rough handling
may indicate internal damage in the air cleaner. Carefully unpack the unit and examine it for
concealed shipping damage. If the unit is damaged, contact the carrier to file a claim.
Carefully read the entire manual before starting installation. Authorities having jurisdiction should
be consulted prior to installation. Permits may be required. If there are no local codes, installation
should conform to the National Electrical Code. The electrical supply, volts, amps, hertz, and
phase, must correspond to that on the unit rating plate. Refer to dimensional drawings for the inlet
and supply dimensions for the duct connections, electrical inlets, and unit clearances before
setting the unit in place. The supply side duct opening at the discharge end of the unit is small
and operates at high velocity. A gradual transition to the larger supply duct should be used and
extra care taken to prevent the accidental dislodging of internal duct insulation in the transition.
Take note of the side clearance required to access blower motor and drive belts, and the space
required to replace the filters. Recommended minimum side clearance is 25" on the door side
and 12" on the power side.
The Series 3000 can be wired for 230 or 460 line voltage. Typical running amps at 230 volts
range from 8.3 to 13 amps depending on the filter configuration and external static load. The
schematic below illustrates the wiring required for each line voltage. The control box will
accommodate conduit from 1/2" to 1 1/4" in each of two bottom knockouts. Field wire the unit with
wire suitable for a 30 amp service and a full load of 13 amps.
