GREENHECK SP-A70 Ceiling Exhaust And Inline Fans

Product Information

The Model SP and CSP Ceiling Exhaust and Inline Fans are designed for clean air applications where low sound levels are required. These fans offer options and accessories such as lights, motion detectors, ceiling radiation dampers, and speed controls. They are available in various models and sizes.

Product Usage Instructions

1. Before attempting to assemble, install, operate, or maintain the fan, please read and save the provided instructions for future reference.
2. Observe all safety information to protect yourself and others.
3. Failure to comply with the instructions may void the product warranty and result in personal injury or property damage.
4. For optimal performance, use the shortest and straightest duct routing possible when connecting the fan to the outside of the building.
5. Avoid installing the fan with smaller ducts than recommended.
6. Consider using insulation around the ducts to reduce energy loss and inhibit mold growth.
7. Note that fans installed with existing ducts may not achieve their rated airflow.
8. Use rigid metal duct for optimal fan performance.
9. Keep duct runs short.
10. Seal duct joints and exterior penetrations with caulk or similar material to create an air-tight path and minimize heat loss and gain.
11. Place/wrap insulation around the duct and/or fan to minimize condensation buildup.
12. Seal duct joints with tape.
13. Consider purchasing additional insulation, roof cap with built-in damper, power cable, wall cap with built-in damper, round ducts, and round elbows separately if needed.
14. Refer to the recommended duct dimensions based on the specific model of the fan.
15. For reduced fan noise, consider using fiberglass ductboard instead of metal ductwork. Flexible duct connections can also help reduce sound transmission.
16. Consider the location of the fan before installation. Insulated ductwork, flexible duct connections, or placing the fan in a remote section of ductwork can help meet required sound levels in critical sound installations.
17. It is highly recommended to use an intake filter with these fans to prevent excess dirt accumulation on wheels and motors, which can lead to reduced performance and imbalance.

• Fan/Light combination not to be installed in a ceiling thermally insulated to a value greater than R40.

CAUTION! For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors.

Typical Installation

The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow. Rigid metal duct is recommended for optimal fan performance. Ensure duct joints and exterior penetrations are sealed with caulk or other similar material to create an air-tight path and to minimize building heat loss and gain and reduce the potential for condensation. Place/wrap insulation around duct and/or fan to in order to minimize possible condensation buildup within the duct, as well as minimize building heat loss and gain.

Other Installation Considerations

• Ductwork and Noise
  Fiberglass ductboard is a better choice than metal ductwork for reducing fan noise and is highly recommended for low sound applications. Where metal duct is used, sound transmission can be reduced with flexible duct connections between the fan and the duct.

• Sound and Location
  The location of these fans must be taken into consideration before installation. In critical sound installations, insulated ductwork, flexible duct connections or placing the fan in a remote section of ductwork are solutions to meeting the required fan sound levels.

• Filters
  The addition of an intake filter is highly recommended for these fans, even in clean air environments excess dirt can accumulate on wheels and motors causing reduced performance and imbalance. Filters, once installed, should be checked and cleaned periodically to maintain performance. Washable aluminum mesh filters specifically designed for these fans are available, please consult your representative for more information.

Prepare the Fan

Power Assembly
If power assembly (motor, wheel, and scroll) is not installed in housing, insert the electrical plug into fan socket, then slide scroll end of power assembly into fan housing. Attach by using two sheet metal screws provided .

Remove Wiring Knockout
Remove either top or side wiring knockout, depending on wiring direction, by bending it back and forth to break tabs.

Ductwork
Check ductwork to see if the fan’s discharge requires rotation from horizontal to vertical discharge.

Fan Rotation
To rotate from horizontal to vertical discharge A Models Only

• A50-510, 710, 780 Models
  Remove the two screws holding the power assembly in and pull power assembly out. Rotate power assembly 180 degrees and put back into fan. Use the same screws to reattach power assembly to fan housing. Flip fan over and remove the four screws holding the discharge duct and damper assembly. Exchange the assembly with plate mounted on top of fan, as shown in these illustrations .

• A700, 900-1500 Models
  Remove the eight screws holding the access panel or collar as shown in picture. Rotate the fan housing so the discharge is facing up. Replace access panel or collar and screws.

Ceiling Radiation Damper (CRD)
If fan is to be used in a fire resistive membrane ceiling, a ceiling radiation damper must be used. If the ceiling radiation damper is already mounted to the fan from the factory, proceed to Install the Fan.

To mount the ceiling radiation damper to fan, make sure grille attachment tabs are facing down. Then place the inlet part of the fan into the ceiling radiation damper collar, and use self-tapping sheet metal screws (by others) to screw through the damper collar and into the fan housing. If the fan/light combination is being used, make sure ceiling radiation damper has an electrical plug in it. The electrical plug must be inserted into the fan. Make sure the electrical wire will not interfere with damper operation as shown in figure below.

General Maintenance Suggestions

Ceiling exhaust fans require very little maintenance, but since small problems over time left unchecked could lead to loss of performance or early motor failure, we do recommend that the unit be inspected periodically (once or twice a year). The fan motor and wheel should be checked for dust and dirt accumulations. Dirt buildup can lead to loss of performance and motor overheating. Cleaning can be accomplished by brushing off any dust that may have accumulated. Even filtered units can accumulate build-up and should be checked when cleaning filters. The motor should be checked for lubrication at this time. Lubricate only those motors which have an oil hole provided. A few drops of all purpose oil (SAE 20) will be sufficient.
