Please read and save these instructions for future reference. Read carefully before attempting to assemble, install, operate or maintain the product described. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or property damage!

Model CW

Direct Drive

Model CW is a direct drive centrifugal sidewall exhaust fan. These fans are specifically designed for wall mounted application. Performance capabilities range up to 6,400 cfm (10,874 m3/hr) and up to

3 in. wg (747 Pa) of static pressure. The maximum continuous operating temperature for fan sizes 098-200 is 400°F (204°C) and for fan sizes 060-095 is 160°F (71°C). CW fans are available in fourteen sizes with nominal wheel diameter ranging from 9 to 20 inches (229 mm to 508 mm) (060 - 200 unit sizes). Each fan shall bear a permanently affixed manufacturer’s engraved metal nameplate containing the model number and individual serial number.

Model CWB

Belt Drive

Model CWB is a belt drive centrifugal sidewall exhaust fan. These fans are specifically designed for wall mounted application. Performance capabilities range up to 12,500 cfm (21,200 m3/hr) and up to 2.75 in. wg (685 Pa) of static pressure. The maximum continuous operating temperature is 400°F (204.4°C).

CWB fans are available in nineteen sizes with nominal wheel diameter ranging from 9 to 30 inches (229 to 762 mm) (098 - 300 unit sizes). Each fan shall bear a permanently affixed manufacturer’s engraved metal nameplate containing the model number and individual serial number.

Only qualified personnel should install this fan. Personnel should have a clear understanding of these instructions and should be aware of general safety precautions. Improper installation can result in electric shock, possible injury due to coming in contact with moving parts, as well as other potential hazards. Other considerations may be required if high winds or seismic activity are present. If more information is needed, contact a licensed professional engineer before moving forward.

DANGER

Always disconnect, lock and tag power source before installing or servicing. Failure to disconnect power source can result in fire, shock or serious injury.

CAUTION

When servicing the fan, motor may be hot enough to cause pain or injury. Allow motor to cool before servicing.

CAUTION

Precaution should be taken in explosive atmospheres.

1.Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the National Fire Protection Agency (NFPA), where applicable. Follow the Canadian Electric Code (CEC) in Canada.

2.The rotation of the wheel is critical. It must be free to rotate without striking or rubbing any stationary objects.

3.Motor must be securely and adequately grounded.

4.Do not spin fan wheel faster than max cataloged fan RPM. Adjustments to fan speed significantly effects motor load. If the fan RPM is changed, the motor current should be checked to make sure it is not exceeding the motor nameplate amps.

5.Do not allow the power cable to kink or come in contact with oil, grease, hot surfaces, or chemicals. Replace cord immediately if damaged.

6.Verify that the power source is compatible with the equipment.

7.Never open access doors to a duct while the fan is running.
