the transport securing device before the fan is ready for immediate installation.
Do not remove the transport securing device until the fan is being installed on the duct or the
roof curb. The motor shaft could be damaged.
NOTE
All single phase fans are shipped with a capacitor and junction box connected via conduit. The
capacitor is located INSIDE the junction box. Please do not discard.

3. Mechanical installation
3.1 Positioning
In accordance with NFPA 96, roof mounted fans shall have their discharge outlet at least 40 inches above the roof surface.
3.2 Installation on steel duct
y Insert the adapter (FR) into the grease duct, where the long collar engage-
ment ensures safe anchoring. (See g. 2).
y If necessary, the adapter can be secured by means of long self-tapping
stainless steel screws into the side of the collar through the chimney wall.
Do not obstruct the grease ow.
y Place the neoprene gasket (not shown) on top of the adapter.
y Remove the transport securing device (if present) holding the motor shaft
and impeller in place.
FR
y Place the exodraft fan on the neoprene gasket centered over the cutout.
y Open the fan and secure the fan onto the adapter, through the pre-drilled
holes in the bottom, with lag bolts or self-tapping sheet metal screws, one
at each corner.
y Check the gasket to insure that it forms a complete seal.
CAUTION
Never place hands or ngers on top of fan base when closing
3.3 Installation on roof curb
y If the fan is supplied with a curb cap, secure the cap to the roof curb with
self-tapping sheet metal screws
(see g. 3).
y Place the neoprene gasket on the top of the curb cap with the hole centered
over the curb cap opening (not shown).
y Remove the transport securing device (if present) holding the motor shaft
and impeller in place.
y Place the fan on the neoprene gasket centered over the cutout.
y Open the fan and secure the fan onto the roof curb, through the pre-drilled
holes in the bottom, with lag bolts or self-tapping sheet metal screws, one at
each corner.

4. Electrical installation
4.1 Electrical requirements
Power requirements are dependent on the fan size and can be found on page 5.
DANGER
Turn o electrical power before servicing. Contact with live electric components can cause shock or
death.
NOTICE
If any of the original wire supplied with the system must be replaced, use similar wire of the same temperature rating. Otherwise, insulation may melt or degrade, exposing bare wire.
4.2 Wiring diagram for GSV 200-315
The connection diagram below shows how the fan is connected to the fan speed control and the power source (see g. 6).
Use a 2-conductor wire of min. 14 AWG with ground. Wiring must be run outside the duct, but can be run between the
duct and the roof curb.
Fig. 5 shows the wiring of the capacitor in the junction box.

4.3 Wiring diagram for GSV 400-450
The connection diagram below shows how the fan is connected to the power source (see g. 7).
Use a 3-conductor wire of min. 14 AWG with ground. Wiring must be run outside the duct, but can run between the duct
and the roof curb.
If variable speed is required, a variable frequency drive (VFD) can be used. This will eliminate the need for a magnetic
starter as shown. For installation and wiring, please refer to the instructions shipped with the VFD.

4.4 Dual voltage motor wiring
GSV 400-450 can operate at either 3 x 208-230 VAC (default) or 3 x 380-420 VAC.
The motor wiring terminals in g. 8 show default jumper positions for 3 x 208-230 VAC operation.
Fig. 8
If the application requires 3 x 380-420 VAC operation, the jumper positions must be changed according to g. 9.

After wiring, make sure the motor is rotating in the proper direction. This is marked on the motor end cover. If the rotation
is incorrect, swap the two wires going to the motor terminals, U1 and W1.
5. Start-up and conguration
5.1 System testing
y Check the voltage with the motor nameplate rating.
y Check that the transport securing device holding the motor shaft and impeller in place has been removed.
y Determine if the impeller is free and has not been subject to misalignment in shipping or installation.
y Apply power and check that the impeller is rotating in the direction of the arrow on the side of the top motor cover.
All exodraft fans run in a clockwise direction when viewed from the top. Double check if three phase motor is
tested on temporary wiring. Switching any two leads will reverse the rotation.
5.2 Adjusting the fan speed
y Start all heating appliances connected to the chimney with the fan installed. Set the fan speed control to the speed
where no spillage is experienced anywhere in the system.

6. Maintenance and troubleshooting
6.1 Maintenance intervals
The exodraft Grease Fan is designed for prolonged use. For dirty or grease-laden exhaust, inspect the impeller after (3)
months and set up a periodic inspection based on these ndings. Clean as required.
The fan motors are equipped with permanently lubricated sealed ball bearings. They require no lubrication.
6.2 Cleaning
WARNING
Do not open the motor housing unless power to
the grease fan has been disconnected
y Loosen the two Phillips screws in the front of the unit.
y Tilt the top of the fan by lifting on the handle. Make sure the
locking arm holds the top of the fan before letting go.
y If necessary, use grease remover and a high-pressure cleaner
to clean the impeller and the inside fan base.
y A scraper may also be used.
CAUTION
Never place hands or ngers on top of fan base when closing.
