SAFETY INSTRUCTIONS

NOTICE
DVK100B fans are not explosion-proof and should not be used when a potentially explosive situation exists. Do not use where temperatures will exceed 140 F/60 C.

1. Ensure that the electrical service to the fan is locked in the “OFF” position. Do not re-establish the power supply until the fan and activation device are completely installed.

2. DVK100B fans are not suitable for outdoor use.

3. This unit has rotating parts! Safety precautions must be exercised during installation, operation, and maintenance. Turn the impeller by hand to make sure it rotates freely.

4. For general ventilation use only. Do not use to exhaust hazardous or explosive materials and vapors.

5. To reduce the risk of fire, electric shock, or injury to persons — observe the following:
   a. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the factory.
   b. A qualified person(s) must perform installation work and electrical wiring in accordance with all applicable codes and standards, including fire-rated construction.
   c. The combustion airflow needed for the safe operation of fuel-burning equipment may be affected by this unit’s operation. Follow the heating equipment manufacturer’s guidelines and safety standards as published by the National Fire Protection Association (NFPA), the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE), and local code authorities.
   d. When cutting or drilling into walls or ceilings, take care not to damage electrical wires or other hidden utilities.
   e. Ducted fans must always be vented to the outdoors when used to exhaust moist/humid air.

6. Check the voltage at the fan to see that it corresponds to the motor nameplate.

DVK100B-C KIT

Kit includes:

CURRENT SENSOR

The CS120V-AF current sensor has a preset actuation point (1.25 amp min) that enables automatic activation of the DVK duct fan when the dryer is operating and causes the fan to shut off when the dryer cycle is complete.

FAN INSTALLATION

WARNING
Disconnect and lock out the power supply before performing any installation work.
Working on or near energized equipment could result in death or serious injury.
NOTE: The DVK100B dryer booster fan is designed for use in duct runs with an equivalent length between 25 and 110 feet.
NOTE: An auxiliary lint trap (LT100) may be installed between the dryer and the booster fan.
STEP 1. FAN LOCATION
The fan should be mounted a minimum of 15’ from the dryer outlet. Allow sufficient access to the fan for recommended maintenance. Affix ‘Fan Location Label’ in a visible place.

STEP 2. INSTALL FAN
Attach mounting brackets to the fan housing (Figure 1a or Figure 1b).
Please note the airflow direction arrow located on the box cover. Secure the fan to support at the selected location. The fan may be mounted in any position; however, vertical orientation is recommended to reduce condensation build-up in the fan. The terminal box should be positioned for easy access. STEP 3. CONNECT DUCT
A rigid duct is recommended to optimize fan performance. If using a flex duct, it should be stretched as smoothly as possible. For duct runs in unheated spaces, an insulated duct is recommended to reduce the effects of condensation. Connect the duct to the inlet and outlet ends of the fan housing by means of mounting clamps or duct tape and seal to prevent air leakage and loss of fan performance.

CURRENT SENSOR INSTALLATION

STEP 4. INSTALL CURRENT SENSOR
To house the current sensor, secure an approved electrical box to the existing dryer electrical box.
(Alternatively, the current sensor may be mounted at the breaker panel. Consult a qualified electrician).
Securely mount the current sensor in the electrical box. From inside the dryer electrical box, disconnect the neutral (white) power supply wire, loop it through the center of the current sensor, and reconnect it.
STEP 5. CONNECT WIRING
Refer to the wiring diagram on page 4. Reattach all electrical box covers before applying power.

TROUBLESHOOTING

WARNING
Only qualified personnel should work on electrical equipment. Working on or near energized equipment could result in death or serious injury.

1. If the fan fails to start, consult the wiring diagram to ensure proper connection.
2. Check the incoming supply for proper voltage.
3. Ensure that the electrical service to the fan is locked in the “OFF” position.
4. Use a meter to test for continuity across the fan motor leads.
5. If the motor leads show continuity, rewire the fan and current sensor.
6. Turn on the electrical supply and restart. If the fan fails to start, remove the sensor from the circuit.
7. Connect the incoming power supply directly to the fan motor. Turn on the power to the fan.
8. If the fan fails to start, please contact the factory.

RECOMMENDED MAINTENANCE

WARNING
Disconnect and lock out the power supply before performing any maintenance.
Working on or near energized equipment could result in death or serious injury.

1. Fan bearings are sealed. No additional lubrication is necessary.
2. Periodic inspection, based on usage, should be performed to ensure that the fan impeller is not obstructed. The fan should be inspected a minimum of every six (6) months.
3. Excessive fan noise or vibration may indicate an obstructed impeller.
4. To inspect and clean the impeller:
   a) Remove the duct from the fan inlet and remove any obstruction from the impeller.
   b) Reconnect the duct to the fan.
   c) Turn the power supply on.
