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
• Insert the adapter (FR) into the grease duct, where the long collar engagement ensures safe
anchoring (See Fig. 2). 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.
• Place the neoprene gasket (not shown) on top of the adapter.
• Remove the transport securing device (if present) holding the motor shaft and impeller in place.
• Place the fan on the neoprene gasket centered over the cutout.
• 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.
• Check the gasket to insure that it forms a complete seal.
Caution: Never place hands or ngers on top of
fan base when closing
Fig. 2
FR
3.3 Installation on Roof Curb
• If the fan is supplied with a curb cap, secure the cap to the roof curb with self-tapping sheet metal
screws (see Fig. 3).
• Place the neoprene gasket on the top of the curb cap with the hole centered over the curb cap
opening (not shown).
• Remove the transport securing device (if present) holding the motor shaft and impeller in place.
• Place the fan on the neoprene gasket centered over the cutout.
• 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.
• Check the gasket to insure that it forms a complete seal.

4. Electrical Installation
4.1 Electrical Requirements
Power requirements depend on the fan size. They can be found on page 4.
Danger: Turn off 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 250-315
The connection diagram below shows how the fan is connected to the fan speed control and the power
source (see Fig. 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 Fig. 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 3x208-230 VAC (default) or 3x440-480 VAC.
The motor wiring terminals in Fig. 8 show default
jumper positions for 3x208-230 VAC operation.
If the application requires 3x440-480 VAC
operation, the jumper positions must be changed
according to Fig. 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
• Check the voltage with the motor nameplate rating.
• Check that the transport securing device holding the motor shaft and impeller in place has been
removed.
• Determine if the impeller is free and has not been subject to misalignment in shipping or installation.
• Apply power and check that the impeller is rotating in the direction of the arrow on the side of the top motor
cover. All EXHAUSTO fans run in a counterclockwise 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
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 EXHAUSTO 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
• Loosen the two Phillips screws in the front of the unit.
• 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.
• If necessary, use grease remover and a high-pressure
cleaner to clean the impeller and the inside fan
base.
• A scraper may also be used.
Caution: Never place hands or ngers
on top of fan base when closing.
