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 PLF Series Exhaust Fan. Failure to comply with instructions could result in personal injury and/or property damage. Retain instructions for future reference.

GENERAL INFORMATION

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 metal 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

PLF12 to PLF24 Models

Simply remove the fan from the carton and proceed to next section.

PLF36 Models

Remove the fan from the shipping pallet by removing the 6 screws holding the fan to the pallet. A hardware bag is secured to the motor support arm. The hardware bag contains 8 turn clips, 8 nylon washers, 8 10 - 24 × 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 holes. There are 3 holes down each side flange and 1 on each of the top and bottom flanges. 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. Secure the 4 corners with lag bolts. Secure the 4 sides, being sure the inside dimensions of the fan are consistent between flanges so that clips and shutters will operate correctly (see Figure 1-a). This will also ensure that the orifice is not deformed, which may cause the blade to hit the tunnel of the fan.

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 BE SURE POWER IS OFF AT THE ELECTRICAL PANEL BEFORE SERVICING

WARNING ALL ELECTRICAL WORK SHOULD BE PERFORMED BY A QUALIFIED ELECTRICIAN.

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 that was supplied over the shutter notch edges (see Figure 3). The motors supplied with these fans are dual voltage 120/240V (except for 36" 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.

EC (Electronically Controlled) MOTOR SPEED CONTROL

If your unit contains the ECsmart Motor please follow these wiring diagrams:

Please contact Canarm Ltd. for any, and all questions related to electrical or control connections to our EC motors.

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 build-up 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.

BELT DRIVE FAN

Belt drive fans are equipped with an automatic belt tensioner. The rotary tensioner will compensate for any wear or stretching of the belt. No adjustments should be 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. Tightening can be done by moving the screw location on the tensioner bracket. (see figure 4) (Although we recommend replacing the belt).

Lubrication: Belt drive fans are provided with bearing blocks that are pre-lubricated & sealed. They have a double contact seal and steel slinger that prevents most contamination. However, since the bearings are to operate in very damp and dirty conditions, re-lubrication is recommended. The grease fitting of the unit should be carefully cleaned before use and the grease should be introduced slowly. Under normal conditions, the bearings only need re-lubrication every 3 years. Nonetheless, we recommend that each bearing receive one pump from a grease gun (or until fresh grease is pushed out), every time the unit is washed down (especially if detergent is used.)

NOTE: Use NLGI2 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.

Moving parts, disconnect power before servicing.

WARNING

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

Figure 4 Adjusting Belt Tensioner

Remove Bolt

Change screw hole placement. Moving screw towards belt will increase tension.

Use screw from step 2 as pin location for tensioner. Reassemble bolt from Step 1.

NOTE: Remove belt before making adjustments.

ACCESSIONS

Canarm provides a full line of controls from simple on/off thermostats to sophisticated multiple staging controllers and PC based controllers.
