Frequently Asked Questions - HVA24T10075 Canarm

What are the installation prerequisites for the HVA24T10075 fan?

Installation requires a framed wall opening according to the dimensions in the manual (see Typical Installation section). The fan must be securely fastened, and a certified electrician must perform the electrical connection. Ensure power is off before any handling.

How to wire the fan?

Follow the connection diagram on the motor nameplate. Use a properly sized cable, and prevent excess wire from entering the shaft and impeller area. A disconnect switch must be installed nearby to cut power in an emergency.

What safety instructions must be followed?

Turn off power at the electrical panel before any wiring. Do not install the fan in an environment containing combustible materials or gases. If the fan is mounted less than 2 meters from the ground, guards must be used. All electrical work must be done by a qualified electrician.

How to adjust belt tension?

Belt deflection should be 1/64 in per inch of span (midway between pulley centers) when a force of about 5 lbs is applied. Loosen the motor nuts to adjust tension, then retighten. Never force the belt onto the pulley.

When and how to lubricate bearings?

Bearings should be lubricated semi-annually (more frequently in severe conditions) with a high-quality lithium-based grease. With the unit running, add grease slowly using a manual grease gun until a slight bead appears at the seal. Do not overlubricate.

What to do in case of excessive vibration?

Check possible causes: loose impeller or pulley, improperly tensioned belt, bent shaft, unbalanced impeller, loose fasteners, worn bearings. Consult the Troubleshooting section of the manual for corrective actions.

Why is the motor overloaded?

Possible causes: static pressure higher than expected, impeller rotation in wrong direction, incorrect fan speed, defective motor. Check rotation direction, speed, and system pressure.

How to reduce excessive fan noise?

Check belt tension and alignment, bearing condition, impeller balance, and that all fasteners are tight. Noise can also come from high air velocity or lack of insulation.

What periodic maintenance is recommended?

Inspect the fan at least once a year, ideally every 2-3 months. Check fasteners, belt tension, alignment, lubricate bearings, clean dust from motor, panel and wheel. Replace worn belts.

How does the warranty work?

Canarm warrants the fan against defects in materials and workmanship for one year from the date of purchase. They will repair or replace the defective unit (return freight prepaid). The warranty does not cover labor or transportation for removal/reinstallation. Contact customer service before any return.

INSTALLATION CONTINUED

1. Tighten all nuts, bolts and setscrews prior to fan start up (as some may have loosened during shipping).
2. On belt driven fans make sure that the belts are tensioned and aligned correctly.
3. Ensure that all protective guards and other safety devices are installed properly prior to fan start up.

WARNING: GUARDING SHOULD BE USED IF FANS ARE MOUNTED LOWER THAN SEVEN FEET (2 METRES) OFF FLOOR OR GROUND LEVEL.

STANDARD WIRING INSTRUCTIONS

1. A qualified electrician in accordance with all local and National Electrical Codes should do all wiring.
2. Lock off all power sources before any wiring is to be performed.
3. Leave enough slack in the wiring to allow for motor movement when adjusting the belt tension.
4. Excess wire must be restrained in order to prevent it from entering the shaft and propeller area.
5. Disconnect switches are recommended and should be located near the fan in order to, swiftly cut off power in case of an emergency and maintain complete control of the power source.
6. Some motors may have to be removed in order to make the connections in the motor terminal box.
7. Follow the wiring diagrams on the motor nameplate.

1. Wall Fans

• Extend the proper gauge wire to the fan motor.
• Restrain excess wire from entering the shaft and propeller area

2. Wall Fans with Cabinets

• Remove guard from cabinet.
• Drill a hole through the cabinet at a convenient location and pull the wires through (never wire through the guard).
• Restrain excess wire from entering the shaft and propeller area

OPERATION

Pre Start Inspection

• Lock out all power sources
• Inspect all fasteners and set screws and tighten as required
• Inspect belt alignment and tension
• Confirm power source voltage and motor voltage are the same and that the motor is wired correctly
• Rotate the fan blade to ensure that neither the fan blade nor the belts come into contact with the housing
• Inspect the fan and the ductwork to ensure they are free of debris
• Check to ensure that all guards and accessories are securely mounted
• Check to be sure the propeller rotation is correct

OPERATION CONTINUED

Typical Installation - Refer to page 7

Start Up

Turn the fan on and inspect for the following.

• Direction of rotation
• Improper motor amperage
• Excessive Vibration
• Unusual Noise
• Improper belt tension or alignment

If a problem is discovered shut off the fan and refer to the section on troubleshooting to discover the cause of the problem. The fan should be inspected after 30 minutes, 8 hours and 24 hours of operation to ensure all fasteners are tight and belts are properly tensioned and aligned.

MAINTENANCE WARNING

Disconnect and secure to the OFF position all electrical power to the fan prior to inspection or servicing. Failure to comply with this safety precaution could result in serious injury or death.

• Ventilators should be checked at least once a year. For critical or severe applications a routine check every two to three months is suggested.
• When removing or installing a belt don't force the belt over the sheave. Loosen the motor mount so that the belt can be easily slipped over the sheave.
• The belt, on belt driven units, should be removed and carefully checked for cracks, ply separation or irregular wear. A small irregularity in the contact surface of the belt will result in noisy operation. If any of these defects are apparent the belt should be replaced. At the same time check the sheaves for chips, dents or rough surfaces that could damage the belt.
• The correct belt tension is important. Too tight a belt will result in excess bearing pressure, which can cause premature bearing failure and may cause the motor to overload, too loose a belt will result in slippage, which will burn out belts. Proper belt deflection should be 1/64" (half way between sheave centers) for each inch of belt span when a force of approximately 5 lbs. is applied.
• The belt alignment should be checked to be sure that the belt is running perpendicular to the rotating shafts. Motor and drive shafts must be parallel.
• A periodic inspection of all fasteners should be carried out to ensure they have not loosened due to vibration. Particular attention should be paid to fasteners attaching the wheel to the shaft and those attaching the shaft to the bearing.
• The standard pillow blocks on belt driven fans are factory lubricated. These bearings should be lubricated on a semi annual basis (more frequently in severe applications) using a high quality lithium based grease. With the unit running add grease very slowly, using a manual grease gun, until a slight bead of grease forms at the seal. Be careful not to unseat the seal by over lubricating or by using excessive pressure. When the bearings are obstructed from view use no more than three injections with a hand operated grease gun.
• Dust and dirt on the exterior surface of the motor, fan panel and the entire fan wheel should be removed, at intervals determined by the severity of the application, to ensure proper service life and safety.
• For additional safety information refer to AMCA publication 410-96, Safety Practices for Users and Installers of Industrial and Commercial Fans

Belt Tension

BELT AND PULLEY REPLACEMENT

In the course of regular maintenance the belts and pulleys may have to be changed and or adjusted the recommended procedure is as follows.

• Do not change the pulley pitch diameter in order to tension the belts. This will result in a change in the fan speed.
• Loosen the nuts on the motor plate or motor in order to reduce the belt tension such that the belts will easily slip over the pulleys. Never force the belts over the rim of the pulley.
  Loosen the setscrews on the pulleys and remove from either the motor or fan shaft using a two or three jaw puller.
• Remove any shaft imperfection such as setscrew mark using a file or emery cloth.
• Install the replacement pulleys tightening all setscrews to the recommended torque rating (see chart) and ensuring that they are properly aligned.
• Pulley alignment is achieved by moving the pulleys on their respective shafts or moving the entire motor until the pulleys are correctly aligned (see figure). Using a square with one edge parallel to the motor shaft adjust the pulleys until the other edge is parallel to the belts.
• Slip the belts over the pulleys then adjust the motor/ motor plate until the proper tension is reached (1/64" deflection, half way between pulley centers, per inch of belt span when pressed firmly).
• Tighten the motor plate/ motor adjusting nuts in place.

PULLEY ALIGNMENT

M0112_NOV 2020 Page 4 of 8WWW.CANARM.COM

REplacement

Canarm Ltd. uses pillow block bearings.

Before removing the bearings mark the positions of the fan blade, bearings and pulley on the shaft.
Note the clearance between the fan blade and the venturi.
- Remove the pulley and fan blade from the shaft using a puller.
- Unbolt the bearings and remove the shaft and pillow blocks as one unit.
- Clean the shaft and remove any marks using a file or emery cloth then remove the bearings using a bearing puller.
- Inspect the shaft and replace if necessary.
- Mount the new bearings on a section of the shaft that is not worn by tapping the inner ring face using a soft mallet.
Align the setscrews on the bearings and then tighten one setscrew on each bearing.
- Loosely install the bearings on the bearing mount.
- Rotate the shaft to find the center of free movement.
Install the propeller adjusting the bearing location to center the blade in the venturi.
- Tighten the bearing bolts to the proper torque rating
- Turn the propeller by hand the propeller should rotate freely with the same resistance as before the bearing bolts were tightened.
- Tighten all setscrews to the proper torque rating
Install pulley and adjust belt tension.

You should go through the start up steps as outlined above.
