Frequently Asked Questions - 936 Canarm

How to install the Canarm 936 fan?

Before installation, ensure the wheel rotates freely. Attach the fan pulley to the shaft, then mount the motor pulley. Position the motor on the base, align the pulleys and tension the belt using the adjusting bolt. Refer to the assembly diagram in the manual.

What is the ideal belt tension?

The ideal tension is the lowest tension at which the belt does not slip during startup under maximum load. Excessive tension wears out bearings prematurely. Check after 50 to 100 hours of operation.

How to align the fan pulleys?

The straight edge of the drive pulley face must be parallel to the belt. Use a ruler to check alignment. Adjust the motor position on the base if necessary.

When should the bearings be replaced?

In case of abnormal noise or excessive play. To replace, loosen the set screws, remove the old bearing. Install the new one by turning the locking collar in the direction of rotation until tight, then tighten the set screw.

How to clean the fan wheel?

Disconnect power. Periodically clean the blades with a lint-free cloth. Buildup of material can unbalance the wheel and cause failure.

What is the grounding procedure?

A ground wire must be connected from the motor housing and unit frame to an appropriate electrical ground. Ensure power is off and locked out before any connection.

Can I use a lubricant other than Shell Alvania for the bearings?

It is recommended to use Shell Alvania #2 or S3. Excessive greasing or incompatible lubricant can damage seals and bearings.

How to check the rotation direction of the wheel?

Momentarily power the unit and observe rotation. The wheel must rotate in the indicated direction. If reversed, swap two electrical phases.

What to do if the belt slips?

Increase tension using the adjusting bolt. If the belt is worn or cracked, replace the entire set of belts with a matched set. Do not use belt dressing.

What are the risks if rotating parts are not guarded?

Rotating parts (pulleys, shaft, belts) can cause serious injury. They must be protected by ducts, cabinets or covers. Do not open access doors during operation.

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/Delhi 400/800/900 Series. Failure to comply with instructions could result in personal injury and/or property damage. Retain instructions for future reference.

BEFORE YOU BEGIN

Inspect unit for damage, report any shipping damage to carrier. Check all fasteners, re-tighten as required. Rotate the blower wheel by hand to ensure free rotation. If rubbing occurs, loosen the set screw(s), re-position the wheel to the shaft center, re-tighten set screws.

INSTALLATION

1. Prior to installing the motor, ensure the wheel rotates freely by turning by hand. If rubbing occurs, loosen the wheel set screws and re-position the wheel to the centre of the shaft. Retighten all set screws.
2. Establish the preferred discharge direction and re-tighten by fastening through the frame holes located at the bottom of the blower.

MOTOR, PULLEYS & BELTS

1. Mount the blower pulley on the blower shaft and tighten the set screw securely on the key of the shaft.
2. Mount the motor pulley on the motor shaft. Leave some clearance between the pulley and the motor end bell.
3. Position the square head bolts in the groove of the motor mounting bracket and install the motor loosely on the bracket using the hardware provided. Bolt the motor adjusting leg to shaft side of the motor base.
   NOTE: This may not be applicable if an optional motor plate was purchased (see Figure 5).
4. With the adjusting bolt in the minimum position, install the V belt(s) within the sheave grooves. Position the motor on the motor bracket to ensure proper pulley alignment (see Figure 6) and tighten the motor mounting hardware to secure the motor position. (A straight edge across the face of the driven pulley should be parallel to the belt once proper alignment has been achieved).
   NOTE: Adjustments in the variable speed pulley require pulley realignment.
5. Tighten the adjusting bolt to tension the V-belt and lock in place using the keps nut (see Figure 4).
   NOTE: Ideal belt tension is the lowest tension at which the belt will not slip during start up.

WARNING

EXCESSIVE BELT TENSION IS THE MOST FREQUENT CAUSE OF BEARING WEAR AND RESULTING NOISE. PROPER BELT TENSION IS CRITICAL FOR QUIET EFFICIENT OPERATION.

Ideal belt tension is the lowest value under which belt slip will not occur at peak load conditions.

ELECTRICAL

WARNING

ENSURE POWER SUPPLY IS DISCONNECTED & LOCKED OUT PRIOR TO MAKING ELECTRICAL CONNECTIONS.

Before connecting the motor to the electrical supply, check the electrical characteristics and wiring instructions as indicated on the motor nameplate or inside the conduit box cover to ensure proper voltage and phase. Complete electrical connections as indicated.

WARNING

A GROUND WIRE MUST BE CONNECTED FROM THE MOTOR HOUSING TO A SUITABLE ELECTRICAL GROUND.

WARNING

A GROUND WIRE MUST BE CONNECTED FROM THE UNIT CHASSIS TO A SUITABLE ELECTRICAL GROUND.

OPERATION

1. Complete the electrical connections, energize the unit momentarily and ensure proper wheel rotation.
2. Apply full power.
3. With all ducts attached, the access doors in place and the air system in full operation, measure the motor current and ensure that it is less than the rated full load motor amperage as indicated on the motor nameplate.

MAINTENANCE

WARNING

ENSURE POWER SUPPLY IS DISCONNECTED & LOCKED OUT PRIOR TO MAKING ELECTRICAL CONNECTIONS.

1. Inspect and tighten all bearing collar and wheel set screws after the first 50 to 100 hours of operation and periodically thereafter.
2. Follow motor manufacturer's instructions for motor lubrication. Remove any excess lubrication.
3. Check the drives.

a. Tighten set screws on pulleys, wheel and bearing locking collars.
b. Check belt tension and alignment.
c. Replace cracked or worn belts.

1. Blower bearings are permanently lubricated and require no further lubrication.
2. Inspect V-belts for wear and proper tension. If it is necessary to replace one belt on a multiple belt drive, replace all the belts with a matched set. Do not use belt dressing.
3. Clean the blower wheel periodically. Material build up on the blades can cause wheel imbalance which may result in wheel or bearing failure.
4. To reinstall replacement ball bearings on spider bearing bracket assemblies, press the locking collar against the inner ring of the bearing and turn in the direction of the shaft rotation until engaged. Insert a drift pin into the pin hole and tap lightly to set. Tighten set screw on locking collar firmly. (see Figure 7). If replacing the pillow block bearings, simply loosen the set screws and remove the mounting hardware. When re-installing, bolt the pillow block to the T-bar support, then position the set screw to be parallel and on top of the key stock of the shaft. Torque set screw to specified values.
5. Spider bracket bearings come pre-lubricated from the manufacturer, and require no re-lubrication. Pillow block bearings are pre-lubricated by the manufacturer. Generally, these bearings should be lubricated at six to twelve month intervals. The recommended lubricant is Shell Alvania #2 or S3. A small amount of grease should be added slowly when the shaft is rotating. Note: Over greasing may cause damage to the bearing. Avoid rupturing the bearing seal.
6. Should further service to the blower be necessary, refer to the exploded view illustration (see Figure 8).
