1. The compactness of the FG/K series, plus the adaptability to be mounted in any position, permits easy installation. This straight-thru air flow fan can be mounted at any angle from horizontal to vertical.

2. Because this unit has rotating parts, safety precautions should be exercised during this phase 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. For FG/K Series fans, if bracket is used to mount fan, refer to illustration 1. If suspending fan with hanger straps, refer to illustration 2.

6. To attach duct work, use duct tape at inlet and outlet to assure good seal. If using FANTECH FC clamps: attach FC clamps and insert screws through clamp into inlet and outlet flanges.
   CAUTION: Use 1/2″ sheet metal screws to secure duct work to inlet and outlet. It is critical that the screw penetrate the metal of the inlet flange but not so far as to bind the impeller. It may be necessary to angle screws away from impeller.
   CAUTION: If not using FANTECH FC clamps use 1/4″ screws.

7. Screen guards must be installed when fan will be within reach of personnel, within seven (7) feet of working area, or when advisable for safety.

8. An appropriate duct termination device (roof cap, wall cap, louvered shutters, etc.) are to be used with this fan.

WARNINGS

1. WARNING! 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 any questions, contact your manufacturer’s representative.
   b. Before 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.
   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 Protection 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 exhaust 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.

2. WARNING! TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK.

INSTALLATION DIAGRAM FOR MODEL FG/K DUCT FANS

1. When installing, keep the number of elbows and bends to a minimum. If necessary, long radius elbows or bends are
   recommended.

2. Duct sealant, caulk, or tape should be applied to all seams, including around the opening in the wall or ceiling on the interior and around exterior building penetrations, to prevent air leakage and maximize air performance.

3. Flex, spiral, or snap lock ducting may be used. If using rigid duct, Fantech FC clamps are recommended to connect duct work to the fan (see illustration 2). FC clamps make an air tight seal at the connection points and reduce vibrations transmitted throughout the duct system. If screws are used, do not locate them in the entrance duct less than half an inch from the housing (see illustration 3).

4. To minimize static pressure losses and promote adequate airflow, minimize duct run lengths where possible. If using flex duct, keep duct runs straight and taut.

5. If installing in an unconditioned space, covering the fan with insulation is recommended to prevent condensation from forming.

6. For general ventilation applications, at least 8 ft of insulated flexible duct shall be installed between the exhaust or supply grille(s) and the fan.

The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow.

Illustration 1

Use long screws (bracket-wall) to mount the bracket and short screws (bracket-fan) for fan.

Illustration 2

Illustration 3
When connecting duct to the fan, do not screw less than 1/2″ from the housing, it may block the blades.

SPECIAL WIRING PRECAUTIONS

All installation should be wired according to the following diagrams.
Failure to comply will cause the motor to “hum” or not work.
Maximum torque that can be applied to the terminal block screws is 0.79 Nm (7 lb-in).

Note:
Cable gland must be used for outside applications.

Note:
Model FGC comes pre-wired with three prong power cord.

Note:
Fans are furnished with either 120V motors or 230V motors. The motors are not dual voltage.

TROUBLESHOOTING

If fan fails to operate, please check the following:
a. Consult wiring diagrams included to ensure proper connections.
b. To ensure proper contact, check motor lead wiring, incoming supply wiring and capacitor connections.
c. If possible, use a meter to test for continuity between fan leads.
Please note capacitor will show no reading if tested with meter.

MAINTENANCE

1. Since fan bearings are sealed and have been provided with an internal lubricating material, no lubrication is necessary.
2. Once a year, remove any airborne particles in the impeller. No other maintenance is required.

For installations in which the fan is connected to a range hood, or if an exhaust grill connected to the fan is located above or near the cooking surface, as shown, be sure to observe the following safety warning:

WARNING!!
TO REDUCE THE RISK OF FIRE, USE ONLY METAL DUCTWORK.
Use only galvanized steel ductwork in accordance with all applicable codes.
NOTE : If the fan is not connected to a range hood, or a grill in the vicinity of the cooking surface, other approved ducting may be used. Check your local codes.)

TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE :
A. Never leave surface units unattended at high settings. Boilovers cause smoking and greasy spillovers that may ignite. Heat oils slowly on low or medium settings.
B. Always turn hood ON when cooking at high heat or when flambeing food (i.e. Crepes Suzette, Cherries Jubilee, Peppercorn Beef Flambé’).
C. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
D. Use proper pan size. Always use cookware appropriate for the size of the surface element.

TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE TOP GREASE FIRE, OBSERVE THE FOLLOWING :
A. SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS. If the flames do not go out immediately, EVACUATE AND CALL THE FIRE DEPARTMENT.
B. NEVER PICK UP A FLAMING PAN – You may be burned
C. Do not use water, including wet dishcloths or towels – a violent steam explosion will result.
D. Use an extinguisher ONLY if:

1. You know you have a Class ABC extinguisher, and you already know how to operate it.
2. The fire is small and contained in the area where it started.
3. The fire department is being called.
4. You can fight the fire with your back to an exit.

For updated documentation please refer to www.fantech.net

To ensure quiet operation of ENERGY STAR® qualified inline and remote fans, each fan shall be installed using sounds attenuation techniques appropriate for the installation.
For bathroom and general ventilation applications, at least 8 feet of insulated duct shall be installed between the exhaust or supply grilles(s) and the fan. For kitchen range hood remote ventilation applications, where metal duct is generally required by code, a metal sound attenuator shall be installed between the range hood and the fan.
