Installation Instructions for
Model KDRE
Installation
1. The compactness and adaptability of the KDRE Series fans permit easy installation. The fans are shipped fully assembled and can be mounted at
any angle. For various mounting, see figures on the following page.
2. Because this unit has rotating parts, safety precautions should be exercised during all phases of installation, operation and maintenance.
3. CAUTION: “For General Ventilation Use Only. Do Not Use To Exhaust Hazardous Or Explosive Material and Vapors.”
4. Remove unit from package and inspect within 15 days after receipt. If damaged, report damage to carrier. Do Not operate this unit with visible
damage to the blower or impeller assembly.
5. CAUTION: “This unit has an unguarded impeller. Do not use in locations readily accessible to people or animals.”
WEAR HAND PROTECTION AND STAY CLEAR OF SHARP EDGES!
6. Screen guards must be installed when fan will be within reach of personnel, within (7) feet of the working area, or when
advisable for safety.
7. PLEASE read the entire manual before installing.
Warnings
DO NOT CONNECT POWER SUPPLY until fan is completely installed. Make sure electrical service to the fan is locked in “OFF” position.
1. All fans are suitable for use with solid-state speed control. Three phase units must be wired through a motor contactor.
2. WARNING! TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS - OBSERVE THE FOLLOWING:
a. Use this unit in the manner intended by the manufacturer. If you have any questions, contact your manufacturer’s
representative or contact us directly.
b. CAUTION: Before installation, servicing or cleaning unit, switch power off at service panel and lock the service disconnection means to prevent
power from being switched on accidentally. When the service disconnection means cannot be locked, securely fasten a prominent warning
device, such as tag, to the panel.
c. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and
standards, including fire-rated construction.
d. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back
drafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those
published by the National Fire Association (NFPA), and the American Society for Heating Refrigeration and Air-Conditioning Engineers (ASHRAE),
and the local code authorities.
e. When cutting or drilling into wall and ceiling, do not damage electrical wiring and other hidden utilities.
f. Ducted fans must always be vented to the outdoors.
g. If this unit is to be installed over a tub or shower, it must be marked as appropriate for the application and be connected to a GFCI (Ground
Fault Circuit Interrupter) - protected branch circuit.
h. NEVER place a switch where it can be reached from a tub or shower.
3. WARNING! Check voltage at the fan to see if it
corresponds to the motor name plate.
WARNING
Before installation, servicing or cleaning unit, switch power off at service panel and lock
the service disconnecting means to prevent power from being switched on accidentally.
When the service disconnecting means cannot be locked, securely fasten a prominent
warning device, such as a tag, to the service panel.
