EC (Electronically Controlled) MOTOR SPEED CONTROL
If your unit
contains the
ECsmart
Motor
please follow
these wiring
diagrams:
Fans are designed to operate with simple on/off switches, or can be wired into sophisticated controls. Some fan models are designed to
run at variable speed while others are single speed only. Varying a single speed fan will cause the motor to fail.
Fan labels should indicate whether or not fan is variable speed. If unsure contact a Canarm representative with the fan model number at
our head office.
OPERATION
MAINTENANCE
These fans are used in a variety of applications and therefore maintenance schedules will vary. In general, no more than 1/16" of dirt
build-up should occur on blade, motor, guard, and louvers for proper fan operation and to prevent premature failure. The complete fan
should be washed down on a regular basis to maintain the high efficiency of the fan. Particular care should be taken to clean louvers, fan
blades front and back, and front guards for better air moving performance. The motor should be kept clean to prevent overheating and
premature failure. As with all mechanical equipment scheduled inspections should include checking that all hardware is secure and blade
set screws are tight. We suggest as a minimum, that this be done after every grow out, in livestock applications.
WARNING
MOTORS ARE EQUIPPED WITH AUTOMATIC OVERLOAD PROTECTION AND MAY RESTART
WITHOUT WARNING. ALWAYS DISCONNECT POWER BEFORE ATTEMPTING TO SERVICE.
WARNING:
VARIABLE SPEED FANS SHOULD HAVE THE MINIMUM SPEED SET TO OPEN THE FAN
LOUVERS A MINIMUM OF 1" TO ENSURE PROPER MOTOR COOLING AND PREVENT PREMATURE
MOTOR FAILURE.
