Dimensions

Refer to the diagram for dimensions.

A diagram illustrating the fan dimensions and wall opening is provided.

Installation Instructions

Step 1: Construct the framed opening to the correct size according to the Wall Opening dimensions on Page 1. See Figure 1.

A diagram shows the framed opening in relation to the ceiling and wall.

Step 2: Insert fan into the framed opening from the inside. Place (2) Fastener [D] under the top (2) Fastener [A]. See Figure 2A. While lifting fan up tight to framing, fasten top of fan with the (2) Fastener [A] and [D]. See Figure 2B. Next, fasten bottom of fan, then both sides with remaining (6) Fastener [A]. Install flashing around opening tight to fan and caulk around fan to seal. If fan and shutter needs to be mounted flush to inside wall, See Figure 3 for framing details.

Diagrams illustrate fan installation with fasteners and framing.

Step 3: Remove packaging from cone and guard sections.

Step 4: Place cone sections on ground with rounded side down. See Figure 4.

A diagram shows four cone sections laid out.

Step 5: Stand (2) cone sections up and fasten with (2) Fastener [B] and [C] in the upper 2 holes. See Figures 5A and 5B. Finger tighten only.

Step 6: Stand next cone section up and fasten to previous cone sections as in Step 3. Stand last cone section up and fasten on both sides be sure to only use the upper 2 holes. Finger tighten only.

Diagrams show the assembly of cone sections using fasteners.

Step 7: Lift cone assembly up and slide onto outlet of fan and fasten using (4) Fasteners [B] and [C]. See Figure 6. Finger tighten only. Bolts must be installed from inside to outside.

Diagram shows fastening the cone assembly to the fan outlet.

Step 8: Remove Fasteners [B] and [C] in outer holes. Insert guard into cone with the guard eyelets facing away from you. Make sure each eyelet lines up with a hole in the cone sections, and secure with the (4) Fasteners [B] and [C], previously removed. DO NOT tighten bolts at this time. See Figure 7A, 7B.

Diagrams illustrate inserting the guard and its attachment.

Step 9: Push cone sections together at each joint to tighten cone around guard. Tighten wafer head bolts and nuts at all joints, taking care not to overtighten. Tighten all bolts holding guard in place.

If fan was ordered with 'PR' style shutter proceed to Step 10. If the 'PV' style shutter was ordered then proceed to Step 12.

'PR' Style Shutter Installation

Step 10: Insert Airfoil shutter into fan by sliding the top flange of shutter under top retaining clips and pressing bottom of shutter inward. See Figure 8.

Diagram shows the 'PR' style shutter being inserted.

Step 11: When shutter is in place, open shutter by pulling down on tie-bar, reach into fan through the shutter blades and latch shutter in place with the draw latches in 2 places. See Figure 9.

NOTE: Shutter protrudes from fan 2 15/16". Provide adequate guarding to protect shutter.

Installation is now complete, proceed to Electrical Wiring Section.

Diagram shows the 'PR' style shutter latched in place.

'PV' Style Shutter Installation

Step 12: Slide shutter into back of fan. See Figure 10A. Fasten shutter in place by rotating the side and top shutter clips over the shutter flanges. See Figure 10B. Installation is now complete, proceed to electrical wiring section.

Diagrams show the 'PV' style shutter installation.

Electrical Wiring

Recommended Wire Routing:

As the power cable exits the back of motor form a drip loop and then run power cable down along motor mount and "Zip" tie the cable to motor mount to prevent cable from getting tangled in the prop. See Figure 11. Then run the cable out the drain hole to the circuit breaker or control panel.

A diagram illustrates recommended wire routing.

WARNING: High Voltage, disconnect power before installation.

All wiring should be installed in accordance with National, State, and Local electrical codes. Fans used to ventilate livestock buildings or other rooms where continuous air movement is essential should be connected to individual electrical circuits, with a minimum of two circuits per room. For electrical connection requirements, refer to diagram on motor nameplate and to information enclosed with the Aerotech environmental control to be used.

Single Phase Fans: Motor overload protection should be provided for each fan. A Circuit Breaker Switch or slow blow motor type fuses must be used. See Figure 12. See Aerotech form QM1400 for proper size.

NOTE: A safety cut-off switch should be located adjacent to each fan.

A wiring diagram for single-phase motor overload protection is provided.

KEY:

• L1 = Line 1
• L2 = Line 2
• L3 = Line 3
• H = Hot
• N = Neutral
• G = Ground

Maintenance

The following inspection and cleaning procedures should be performed monthly:

1. INSPECT PROPELLER: Check that propeller is secure on motor shaft and that there are no signs of damage. The blades are of a self-cleaning design and should not require maintenance.
2. CLEAN regularly for best results:
   • FAN MOTOR: Remove any dust accumulation from motor using a brush or cloth. (DO NOT use a pressure washer). A clean motor will run cooler and last longer. At the same time, verify that the motor is secure in its mount.
   • SHUTTER: Carefully clean dust from shutter blades and frame so that shutter opens and closes freely. A brush or cloth should be used.
   • GUARD: Clean any dust or feathers from fan guards using a brush. Dirty guards can reduce airflow.
3. CHECK FASTENERS: For safety, all fasteners should be inspected. Tighten any loose connections.
4. INSPECT FAN CONTROL: With power disconnected, inspect all electrical connections. Wiring should be secure and in good condition. Remove any dust build-up from control case and sensor using a soft brush or cloth. NEVER CLEAN ELECTRICAL EQUIPMENT WITH A PRESSURE WASHER!

WARNING: High Voltage, disconnect power before servicing.

WARNING: Moving parts, disconnect power before servicing.

WARNING: Do not power wash.

Trouble Shooting

WARNING: High Voltage, disconnect power before servicing.

WARNING: Moving parts, disconnect power before servicing.

Winterizing Fan

In most climates, it is probable that the ventilation system will never need to operate at a total capacity during the colder winter months. Consequently, it is advisable to "winterize" those fans which will not be used in cold weather to avoid unnecessary heat loss and condensation.

To winterize, turn fan control "off". Install the insulated closure panel over the fan intake. If you don't have an insulated closure panel, a piece of rigid insulation material can be used. Remember the insulation panel must be removed before warmer weather returns.

NOTE: At least one single speed fan should be left uncovered and with power available to provide air movement in the event of variable speed control difficulties.

Winter Weather Protection

To prevent cone or fan damage from snow or ice sliding off building roof, weather protection must be provided. A weather shelter may be constructed to cover the entire fan, See Figure 13, or snow guards may be placed on the roof, See Figure 14.

Diagrams illustrate weather shelter and snow guard placement.

Snow Guard Suppliers

Note: Snow guards are designed to prevent sudden, dangerous snow and ice slides when attached to the building roof according to manufacturers recommendations. The supplier listing above is given as a reference only. Aerotech does not endorse any specific snow guard product and no performance warranty is implied.

IMPORTANT

Aerotech Ventilation Systems Product and System Warranties DO NOT cover cone or fan damage from external sources.
