Greenheck CUE-080 Installation Manual

Model CUE Direct Drive Upblast Centrifugal Roof Exhaust Fan

Pre-Starting Checks

Check all fasteners for tightness. The wheel should rotate freely and be aligned as shown at right. Wheel position is preset and the unit tested at the factory. However, movement may occur during shipment, and realignment may be necessary. Centering (height alignment) may be accomplished by loosening the set screws in the wheel and moving the wheel to desired position.

Installation

Upon receiving unit, check for any damage and report it immediately to the shipper. Also check to see that all accessory items are accounted for.

Move fan to desired location and fasten securely through mounting holes in base. Shims may be necessary depending upon roofing material thickness. The diagram below shows dimensions for Model CUE.

Access to the motor compartment is accomplished by removing the screws designated “R” in the drawing below. The cover can then be removed and placed on a flat surface in an area protected from strong winds that could blow it off the roof.

The voltage rating of the motor must be checked for compatibility to supply voltage prior to final electrical connection. For NFPA - restaurant applications, the electrical supply must enter the motor compartment through the breather tube. For other non-flammable applications, the electrical supply can be routed through the conduit chase between the curb cap and the bottom of the motor compartment. Consult local code authorities for your specific requirements.

IMPORTANT: UL/cUL 762 Installations are for Restaurant Applications.

A, B, and C motor RPMs are only approved for this installation. All must include the suffix “G”.

A drain trough is provided on all CUE fans for one point drainage of residue. Some means of collection of this residue must be provided by either placing a container directly under the trough or by utilizing an adapter to direct the residue to another location.

13/4"

Dimension “A” is the inside dimension of the curb cap. The roof curb should be 1-1/2" less than the curb cap to allow for roofing and flashing.

*May vary depending on motor size.

Dimensional Data

Wheel Rotation

Direction of rotation is very critical. Improper rotation will result in loss of performance, excessive horsepower and possible motor burnout. Check rotation by energizing the unit only momentarily. The rotation should be as shown in the diagram at right and should be in the same direction as the rotation decals affixed to the unit.

Maintenance

Motor maintenance is generally limited to cleaning and lubrication (where applicable). Cleaning should be limited to exterior surfaces only. Removing dust buildup on motor housing ensures proper motor cooling. Greasing of motors is only intended when fittings are provided. Many fractional motors are permanently lubricated and should not be lubricated after installation. Motors supplied with grease fittings should be greased in accordance with manufacturers’ recommendations. With motor temperatures under 104°F (40°C), the grease should be replaced after 2000 hours of running time as a general rule.

Wheels require very little attention when moving clean air. Occasionally, oil and dust may accumulate causing imbalance. When this occurs, the wheel and housing should be cleaned to ensure smooth and safe operation.

All fasteners should be checked for tightness each time maintenance checks are performed prior to restarting unit. A proper maintenance program will help these units deliver years of dependable service.

Troubleshooting

NOTE: Before taking any corrective action, make certain unit is not capable of operation during repairs.
