CANARM FGI Fiberglass Exhaust Fan Instruction Manual

GENERAL SAFETY

Rotating parts, (pulleys, shafts and belts) on fans should not be exposed. Where these components are not protected by ductwork, cabinets or covers, appropriate guards should be employed to restrict exposure to rotating parts. Access doors should not be opened with the fan operating to avoid foreign objects being drawn into the system. On initial start-up, a careful inspection should be carried out to ensure no foreign material is present which could become airborne in the system.

Read installation and operation instructions carefully before attempting to install, operate or service Canarm Fiberglass Fan. Failure to comply with instructions could result in personal injury and/or property damage. Retain instructions for future reference

GENERAL INFORMATION

Congratulations on the purchase of your new high performance fiberglass fan. This fan is made of materials that ensure long lasting performance and is designed with features that make it one of the most efficient and easy to use and care for fans available today. Your fan comes completely assembled except for the steel turn clips that can be quickly assembled into the pre- drilled holes around the outside flanges of the fan. All fans are tested for proper operation before leaving the factory. Your fan should be installed into a wood frame (see Chart #1 for dimensions).

INSTALLATION

FGl36 and FG48 Models
Remove the fan from the shipping crate. A hardware bag is secured to the motor support arm. The hardware bag contains 8 turn clips, 8 nylon washers, 8 #10-24 x 3/4″ stainless steel screws, and 8 nylon insert nuts. This hardware is for the turn clips that hold the shutter assembly in place. Assemble the 8 turn clips to the pre-drilled 1/4″ holes. For each of the 8 turn clips insert the screw through the hole from the back of the flange, slide on a nylon washer, then the clip, and thread the nut. Tighten the turn-clips with a Phillips screw driver and a 3/8″ socket wrench (see Figure 1-B).

All Fan Models
With the shutter removed, slide the fan into the framed opening. Push the fan up against the top of the frame to be sure the fan slopes downward for drainage to the outside. There are pre-drilled 5/16″ holes for securing the fan with lag bolts. Secure the 4 sides being sure the inside dimensions of the fan are consistent between flanges and square so that clips and shutters will operate correctly (see Figure 1-A). Also it is recommended that you caulk the perimeter of the fan for improved insulation

CAUTION

IF USING EXPANDING FOAM TO INSULATE, MAKE SURE EXPANSION PRESSURE DOES NOT DAMAGE THE HOUSING.

ELECTRICAL CONNECTIONS

If your fan is not provided with a cord, use the following procedure to wire the fan.
**WARNING

**High Voltage, disconnect power before servicing.

When bringing power to the fan, water-tight cable and connectors should be used. The cable will be brought to the motor through the slot provided in the top of the shutter and allowances in length of cable should be considered. Bring the cable down below the height of the motor then back up to the connector in the side of the motor. This will prevent moisture from running down the cable into the motor. On some models, there are holes punched along the lengths of the arms. It is recommended that you use cable ties provided in hardware bag to attach cable to arm (see Figure 2).

Make sure the cord will not interfere with the blade or louvers. To protect the cable, place the grommetting supplied over the shutter notch edges (see Figure 3). The motors supplied with these fans are dual voltage l 20/240V (except for 48″ Direct Drive – 240 volt only), but 240V is recommended to reduce power consumption.

(NOTE: Fans are factory pre-wired for 240V. Follow motor nameplate directions if 120V is desired).

NOTE: Some fans are available with 3 phase motors. These are not factory pre-wired. Follow your local electrical codes for wire sizing based on load, voltage and distance from the power source and use approved electrical connections

OPERATION

Fans are designed to operate with simple on/off switches, or can be wired into sophisticated controls. Some fan models are designed to run at variable speed while others are single speed only. Varying a single speed fan will cause the motor to fail.

Fan labels should indicate whether or not fan is variable speed. If unsure contact a Canarm representative with the fan model number at our head office.

WARNING: VARIABLE SPEED FANS SHOULD HAVE THE MINIMUM SPEED SET TO OPEN THE FAN LOUVERS A MINIMUM OF 1″ TO ENSURE PROPER MOTOR COOLING AND PREVENT PREMATURE MOTOR FAILURE.

MAINTENANCE

These fans are used in a variety of applications and therefore maintenance schedules will vary. In general no more than 1/16″ of dirt buildup should occur on blade, motor, guard, and louvers for proper fan operation and to prevent premature failure. The complete fan should be washed down on a regular basis to maintain the high efficiency of the fan. Particular care should be taken to clean louvers, fan blades front and back, and front guards for better air moving performance. The motor should be kept clean to prevent overheating and premature failure. As with all mechanical equipment scheduled inspections should include checking that all hardware is secure and blade set screws are tight. We suggest as a minimum, that this be done after every grow out, in livestock applications.

WARNING
MOTORS ARE EQUIPPED WITH AUTOMATIC OVERLOAD PROTECTION AND MAY RESTART WITHOUT WARNING. ALWAYS DISCONNECT POWER BEFORE ATTEMPTING TO SERVICE

WARNING

Moving parts, disconnect power before servicing.

BELT DRIVE FAN

Belt drive fans are equipped with an automatic belt tensioner and v-belt. The rotary tensioner will compensate for any wear or stretching of the belt. No adjustments are necessary. Belt will however wear after extensive use. Fan performance will be sacrificed if worn belt is used. Listen for belt “squeeling” on startup. This would indicate that the belt requires changing or tightening.

The tensioner provides adequate tension when the alignment marks are between 2 and 3. (See Figure 4.) To adjust tensioner, loosen the 3/8″ bolt at the back of tensioner. Using a 15/16″ wrench on the front hex, torque the tensioner clockwise until the alignment mark is at 3. Hold the tensioner at this setting while you tighten the 3/8″ bolt to secure the tensioner in this position. Check drive alignment using a straight edge to make sure the belt is centered on the idler. If pulleys are not properly aligned, belts will wear prematurely.

NOTE: Use NLGl2 lithium base grease to ensure compatibility with original grease.

CAUTION: Do not use pneumatic grease guns. Slowly introduce grease with manual gun otherwise bearing seals will be destroyed.

**WARNING

** Moving parts, disconnect power before servicing.

WARNING

WARNING
MOTORS ARE EQUIPPED WITH AUTOMATIC OVERLOAD PROTECTION AND MAY RESTART WITHOUT WARNING. ALWAYS DISCONNECT POWER BEFORE ATTEMPTING TO SERVICE, OR REMOVING SHUTTER.

REPLACEMENT PARTS: See attached appendices for replacement parts.

ACCESSORIES

Canarm provides a full line of controls from simple on/off thermostats to sophisticated multiple staging controllers and PC based controllers. Winter covers are available for colder climates where the fan is shut down for the winter. Performance enhancing cones are available for 24″ to 50″ sizes. These can improve performance and efficiency by approximately 5% for FG50, 7% for FG36 fans, and 9% for FG24 fans.
