CAUTION
The MULTI-FLEX is equipped with a side mounted junction box. All 115V AC units have an ON/OFF
switch and
cord with plug. Three phase units have wiring terminated inside junction box; motor starters and disconnects are not
supplied with the unit (unless purchased as an option), and must meet local and National Electrical Code. Motors
are typically multiple voltage type (e.g. 115/230 or 208/230/480). Make sure connections in motor junction box
correspond to the line voltage you plan to use. Three phase motor starters (manual or magnetic type) must have
properly sized thermal overloads for the voltage and current required at the motors.
Motor checkout should be performed with the unit running,
all filters in place and cabinet doors closed
.
Measured motor current readings should be equal to or below motor nameplate rating. These specifications can be
found on the motor name plate or in the specifications section of this manual.
The single phase 115V AC motors supplied in the MULTI-FLEX have thermal overload protection.
Motor rotation may be changed, if required, by reversing two internal motor leads located under the wiring
cover. The motor cover plate shows an internal schematic of the motor and should be consulted for this operation.

CABINET DOORS MUST BE CLOSED WHEN RUNNING BLOWER. MOTOR WILL BE
OVERLOADED IF RUNNING WITH DOORS OPEN.
WHEN USING THE MULTI-FLEX IN THE PORTABLE CONFIGURATION, DO NOT OVER EXTEND
THE POWER CORD REACH. DISCONNECTING THE POWER SOURCE WHILE UNIT IS IN
OPERATION CAN CAUSE SPARKING.
