ELECTRICAL CONNECTION
Do not connect power supply until tan is completely installed. Make sure electrical service to the tan is locked
in "on' position.
1. All units are suitable for use with solid-state speed control.
2. This unit has rotating parts and safety precautions should be exercised during installation, operation and maintenance.
3. CAUTION: " For General Ventilation Use Only. Do Not use to exhaust Hazardous or Explosive Materials and Vapors".
4. WARNING: To reduce the risk of fire, electric shock, or injury lo persons - observe the following:
a. Use this unit only in the manner intended by the manufacturer. If you have questions, contact the factory.
b. Before servicing or cleaning, switch power off at service panel and lock service panel to prevent fan from
being switched on accidentally.
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 flow is needed for proper combustion and exhausting of gases through the flue (chimney) of
fuel burning equipment to prevent backdrafting. Follow the heating equipment manufacturer's guidelines
and safety standards such as those published by the National Fire Protection Association (NFPA), the American
Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) and the local code authorities.
e. When cutting or drilling into wall or ceiling, do not damage electrical wires or other hidden utilities.
f. Ducted fans must always be vented to the outdoors.
g. Install fan at least five feet above the floor.
h. Acceptable for use over a bathtub or shower when installed in a GFCI protected branch circuit.
i. NEVER place a switch where it can be reached from a tub or shower.
5. Warning! Check voltage at the fan to see if it corresponds to the motor nameplate.
Guards must be installed when fan is within reach of personnel or within seven (7) feet of working level or
when deemed advisable for safety.
WIRING INSTRUCTIONS
STEP 1.
Remove the screws securing the terminal box cover plate located on the fan motor mounting bracket. All fan motor
and capacitor connections are pre-wired to an electrical terminal strip. A ³ ₈" romex type cable restraint connector will
be needed to secure the wiring through the knockout provided on the side of the terminal box.
STEP 2.
Bring incoming electrical service through the romex connector and the fan electrical service opening (Refer to 1"
opening, Dimensions 'G' & 'H'). Be sure to place the connector nut over the wiring coming into the terminal box.
For Models RVF4 – RVF8XL, the fan motor capacitor is loose in the terminal box. Move the capacitor to allow
access to the terminal strip (see lllustration #3). There are two open ports on the terminal strip. Using a small
regular screwdriver, tighten the neutral (white) wire of the incoming supply under the open terminal strip port
labelled 'N'. Tighten the line (black wire of the incoming supply under the open terminal strip port labelled 'L'.
Secure the ground wire beneath one of the terminal box mounting screws as indicated in the illustrations.
STEP 3.
Secure the romex connector. Secure the incoming supply with the romex connector. Place the capacitor back into
the terminal box. Replace the fan terminal box cover.
All fan motor and capacitor connections have been pre-wired from the factory. No additional fan wiring is necessary.
TROUBLESHOOTING
If fan fails to operate, please check the following:
1. Consult wiring diagrams (page four of these instructions) to assure proper connection.
2. Check motor lead wiring, capacitor leads and incoming supply leads to assure definite contact.
3. If possible, use a meter to test for continuity across the fan motor leads. In order to do this, the capacitor
must be disconnected (do not test the capacitor - it will not meter continuity). If motor leads show continuity,
consult factory for a replacement capacitor.
MAINTENANCE INSTRUCTIONS
1. Since fan bearings are sealed and provided with an internal lubricating material, no additional lubrication is necessary.
2. When using in a dryer boosting application, DISCONNECT POWER SUPPLY and check impeller periodically
for lint buildup.
No other maintenance is necessary.
