Frequently Asked Questions - PW-8SX Canarm

What is the first thing to do before installing the PW-8SX fan?

Before installation, carefully inspect the packaging for any damage. Note any damage on the bill of lading and claim immediately from the carrier. Verify that the wheel rotates freely and no debris is present.

How to secure the fan to its foundation?

The fan must be installed on a solid and level foundation. Use the 3/8 inch diameter holes provided for this purpose to secure it. The use of vibration isolators is recommended.

What are the electrical risks to be aware of?

Ensure the power supply is locked in the OFF position before any wiring. A ground wire must be connected from the chassis to a suitable electrical ground. All electrical work must be performed by qualified personnel in accordance with local codes.

What to do if the fan wheel rubs against the venturi?

Loosen the bolts securing the inlet to the housing and adjust it until the wheel rotates freely. Also check the set screw of the wheel on the motor shaft and retighten if necessary.

How to maintain the PW-8SX fan?

Establish a regular maintenance procedure. Inspect the fan at least once a year. Check all fasteners, as vibrations can loosen them. Disconnect power before any intervention. Clean the wheel and housing with compressed air.

What are the signs of a ventilation problem?

Reduced airflow may indicate improper wheel rotation, debris in the unit or ducts. Excessive vibration may be due to an unbalanced wheel or loose hardware. If abnormal noise occurs, stop the unit and inspect.

How to check the direction of rotation of the wheel?

Briefly power the unit and observe the direction of rotation of the wheel. It must match the direction indicated on the label. If not, check electrical connections (phase reversal).

What to do if the fan does not start?

Check the power supply: circuit breakers and fuses. Make sure the voltage matches the motor requirements. If the problem persists, the motor may be defective and should be replaced. Contact Canarm.

What is the warranty for the Canarm PW-8SX fan?

Canarm warrants the fan against defects in materials and workmanship for one year from the date of purchase. Canarm will repair or replace the unit or its parts, returned freight prepaid. The warranty does not cover labor or transportation.

Can I use the fan without ducting?

Yes, but if the inlet or outlet is not ducted, you must install adequate protection to prevent contact with high-speed rotating parts. Install a protective guard.

INSTALLATION

1. Carefully remove the PW and any associated parts from its crate. The skid can be used to help lift it to its installation site.
2. Inspect the unit and make sure the fan wheel rotates freely. Inspect all hardware and fasteners, some may have loosened during shipping. Make sure the unit is free of all foreign debris. Use caution when lifting the unit, some models may be very heavy.
3. The blower should be installed on a properly designed foundation. It can be secured using the multiple 3/8" diameter holes provided
4. If you need to modify the unit for any reason to install it, do so under the supervision of a licensed mechanical contractor or contact Canarm before making any alterations.
5. Once secured, complete all required duct connections. Any un-ducted orifice should be guarded to avoid contact with rotating parts.
6. Make sure the motor compartment is free and clear and can be accessed in case of service. Rotate the wheel, it should spin freely and not make any sound that would indicate the wheel is rubbing against any debris or the venturi itself.
7. All Wiring must be completed by qualified personnel only and done in accordance with local codes. Refer to the motor's name plate for details. Ensure branch power supply matches the motor requirement. Phases, voltages and amperage available on the circuit.
8. Caution: Always ensure the power is locked out in the off position prior to performing any electrical work.
   When complete, have qualified personnel inspect the unit prior to energizing. 9.
9. Briefly energize the unit and ensure the wheel rotation matches the sticker indicating proper rotation direction. If it does not, check your electrical connections. Check that the amperage drawn matches the motor's FLA as indicated.
10. If you notice any irregular vibration, shut the unit off, lock out power supply, and inspect it. Listen for any irregular sounds. Refer to the trouble shooting section of this manual, or contact Canarm if you need assistance.

ELECTRICAL

WARNING

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

WARNING

ENSURE POWER SUPPLY IS DISCONNECTED AND 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 as shown below. Complete electrical connection as indicated

WARNING

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

PRE-START INSPECTION

Set the main power breaker switch to "OFF" & lockout the power supply. 1.

1. Check all fasteners on the unit and those that may mount the unit to its foundation. Some may have vibrated loose during shipping or handling during set up.
2. Rotate the wheel to ensure that it rotates freely and nothing comes in contact with the housing. If it does see Fig. 4.
3. Verify branch power, and that your motor is wired and suitable for its supply. Failure to do so may cause damage or lead to premature motor failure (Fig. 2).

Check to ensure that all guards and accessories are securely mounted (Fig 3). 5.

1. Once the unit's hardware and power supply are verified, you may proceed to test the unit. Remove any power lockouts and proceed with unit activation.

START UP

Turn the fan on and inspect for the following immediately:

1. Any unusual sound or vibration.
2. Direction of wheel rotation
3. Improper motor amperage

If a problem is encountered, shut off the fan and refer to the section on troubleshooting to discover the cause of the problem. The fan should then be inspected after 30 minutes, 8 hours & 24 hours of operation to ensure all fasteners are tight and the unit is operating correctly.

MAINTENANCE

1. All maintenance and wiring should be completed by qualified personnel in accordance with National & Local Codes.
2. It is recommended to establish a regular maintenance procedure that works within your organization. The ventilator should be inspected at least once a year. More regular inspections are recommended in critical applications.
3. The unit should be shut off and its electrical supply locked out prior to engaging in any maintenance activities.
4. It is recommended to inspect all fasteners periodically. Vibration over time may loosen them.
5. If any new or unknown symptoms are found, refer to the troubleshooting section of this manual or contact Canarm.
6. NOTE: The fan should operate within its design and duty point in the HVAC system. Use outside of its specification could cause damage to the fan or the larger system its connected to.
7. Check static pressure and any accessories like dampers. Check the amperage draw of the motor. These things can be early indicators of issues within the fan or system its connected to.
