1. A qualified electrician in accordance with all local and National Electrical Codes should do all wiring.
2. Ensure power supply is disconnected and locked out prior to making electrical connections.
3. Wire the motor according to the wiring diagram on motor label or on the sticker inside the motor wrap. All motors should be wired to
the same rotation as indicated on the sticker on the top plate.
4. Leave enough slack in the wiring to allow for motor movement when adjusting the belt tension.
5. Excess wire must be restrained in order to prevent it from entering the pulley, shaft or wheel rotating area.
6. Disconnect switches are recommended and should be located near the fan in order to, swiftly cut off power in case of an emergency
and maintain complete control of the power source.
Some single phase direct drive motor’s running RPM can be adjustable with a variable speed control (please contact factory for more
information). The speed control knob starts at off position, then high to low adjust range. At high speed, the speed control would allow the
motor running at its maximum RPM. Dial the knob to the low side would let the speed control regulate the voltage on the motor to reduce
the RPM.
A minimum speed adjustment is needed to limit the motor RPM range. Follow this procedure to set the minimum speed.
1. Motor must be in servicing status to allow the minimum speed setting. Motor would not slow down unless proper load is applied.
Motor RPM would be changed under different system (static pressure).
2. Turn the main control knob to the lowest speed position.
3. Locate and adjust the minimum speed setting, it can be found on the control box itself.
4. Motor RPM range would be from full RPM to the RPM just set.
The lowest minimum voltage that may be applied to the motors is 65VAC. Running at lower voltage can cause premature failure
to the motor.
For 3 phase motors, a variable frequency drive (VFD) is required to adjust motor speed.

STANDARD WIRING INSTRUCTIONS
1. Install roof curb, caulk and flash to ensure the water tightness.
2. Rotate the blower wheel by hand. Wheel should not be rubbing against the housing inlet. If rubbing occurs, loosen the set screws on
the wheel hub and shift the wheel to obtain clearance. Then re-tighten all set screws.
3. Complete all subsequent duct connections.
4. Secure the fan to the curb cap. Do not lift the unit by the hood or motor. Lift the unit by horizontal supports on direct drive or by motor
mounting plate for belt drive unit.
5. Use at least 8 proper fasteners to connect the blower base to the roof curb.
6. Verify if the power supply is compatible with the equipment.
7. Make sure the power line is shut down before wiring the motor to power line.
8. Remove top cap, connect power line to the motor/disconnect switch as indicated.
9. For all up blast units, the electrical supply enters the motor compartment through the vent tube.
10. Ensure all fasteners and set screws are tightened.
11. Place the top cap back on the hood.
12. Caulk and flash the fan base including the fan base corners and roof curb to ensure good water tightness.

Power is connected to the motor and control module through the
junction box and wiring harness provided.
Note: For 115VAC operation the blue jumper provided (taped to wire
harness) must be inserted into motor power
connector. See diagram.
Caution: Operating the motor at 208-230VAC with the jumper will cause significant damage to the motor.
AC Supply - 115/208-230VAC
EC motors are equipped with a control module that allows for accurate manual adjustment
of motor speed. Motor speed range is from 300 to 1800rpm or maximum rpm for that
model.
The control module features a 4 digit LED display that indicates % demand of full speed
and motor speed in rpm. The display also indicates an error code message for minor
diagnostics if required.
Motor speed can be changed by adjusting the speed control pot located on the control
module. A small screwdriver can be used to make the speed adjustment.

EC (Electronically Controlled) MOTOR SPEED CONTROL
Note: EC motors have a soft start
feature. When the power is turned on
the control module gathers information
from the motor then begins the start up
process. After a few seconds the motor
will start to turn and reach full set speed
in 10-15 seconds.

All up-blast models are UL/cUL listed, they are capable to meet UL705 Supplement SC for Commercial Kitchen application:
• The National Fire Protection Association (NFPA) publication NFPA 96 is the primary source for this application. Also consult local
authorities for all other applicable codes and guidelines before installation.
• Exhaust fans used in kitchen ventilation applications must have external wiring. (Wiring must not be installed in the airstream).
• Installation must include a means for inspecting, cleaning and servicing the exhaust fan. (Curb hinge, grease collector and outdoor
disconnect switches are available for purchase as accessories)
• No dampers can be used in the system.
RESTAURANT EXHAUST APPLICATION
1. Lock out all power sources.
2. Inspect all fasteners and set screws and tighten as required.
3. Inspect belt alignment and tension where applicable.
4. Confirm power source voltage and motor voltage are the same and that the motor is wired correctly.
5. Rotate the wheel to ensure that neither the fan blade nor the belts come into contact with the housing.
6. Inspect the fan and the ductwork to ensure they are free of debris.
7. Check to ensure that all guards and accessories are securely mounted.
PRE-START INSPECTION
Turn the fan on and inspect for the following:
1. Direction of rotation.
2. Improper motor amperage.
3. Excessive vibration.
4. Unusual noise.
5. Improper belt tension or alignment (only applicable on belt-drive unit).
If a problem is discovered shut off the fan and refer to the section on troubleshooting to discover the cause of the problem. The fan should
be inspected after 30 minutes, 8 hours & 24 hours of operation to ensure all fasteners are tight and belts are properly tensioned and aligned.

FAN TROUBLESHOOTING
Disconnect and secure to the OFF position all electrical power to the fan prior to inspection or servicing. Failure to comply with this safety
precaution could result in serious injury or death.
1. Ventilator should be checked at least once a year. For critical or severe applications a routine check every two to three months is
suggested.
2. Guard to be kept free of debris. Easily installed/removed using the integrated twist lock tabs. Gently twist the guard tab so that it slips
under the support arm to lock in place. Guard is easily removeable for fan servicing and cleaning. No tools are required.
3. When moving or installing a belt, don’t force the belt over the sheave. Loosen the motor mount so that the belt can be easily slipped
over the sheave.
4. The belt, on belt driven units, should be removed and carefully checked for cracks, ply separation or irregular wear. A small
irregularity in the contact surface of the belt will result in noisy operation. If any of these defects are apparent the belt should
be replaced. At the same time check the sheaves for chips, dents or rough surfaces that could damage the belt.
5. The correct belt tension is important. Too tight a belt will result in excess bearing pressure, which can cause premature bearing failure
and may cause the motor to overload. Too loose a belt will result in slippage, which will burn out belts. Proper belt deflection should
be 1/64” (half way between sheave centers) for each inch of belt span when a force of approximately 5 lbs. is applied.
6. The belt alignment should be checked to be sure that the belt is running perpendicular to the rotating shafts. Motor and drive shafts
must be parallel.
7. A periodic inspection of all fasteners should be carried out to ensure they have not loosened due to vibration. Particular attention
should be paid to fasteners attaching the wheel to the shaft and those attaching the shaft to the bearing.
