6. Installation & Troubleshooting
• Mount the fan on a stable platform via mounting brackets.
• Slide the mounting clamps over air duct
• Slide the air duct onto the flanges on the fan
• Tighten the clamps down with a flat-head screwdriver or a hex socket.
• Plug the 110V plug into a wall outlet to turn on the fan.
If the product had been in storage for more than six months, insulation resistance
must be tested before use. Resistance to ground should be 20MΩ or more. Before
starting the fan, use hands to drive impeller to insure smooth impeller rotation without
obstruction. After connecting the power, observe the impeller rotation direction to be in the
same direction with the nameplate. After confirming everything is functioning properly,
leave it running for half an hour (30 minutes) to test the whether motor will have issues
with overheating or undesirable noises. If the fan does not exhibit any signs of abnormal
operations, it is safe to use and install.
To extend fan life, it is recommended that air filters and one-way valves be installed
on the fan’s inlet and outlet.
The circular fan must only be used indoors and be mounted with non-adhesive
materials. Keep fan clean from dust and foreign contaminants. Both ends of the fan must
be connected to the pipeline.
7. Repairs and Maintenance Notes
Under normal operating conditions, the fan should be cleaned every six months.
Clean any dirt that may have accumulated inside the chassis and dust on the impeller, etc.
Do not use water or any other liquid cleaning agent; use only a clean brush or a clean dry
cloth to wipe away any loose dirt or dust. Proper cleaning ensures the fan operates at
maximum efficiency against the impact of dust without impacting air flow. If it is used in
environments that contain heavy dust, cleaning should occur more often to prevent the
accumulation of dust that would impact normal operations.
Disassembly of the fan is extremely convenient.
• Remove the metal clamps from the flanges
• Remove the duct from the fan
• Dismount the fan from the mounting surface
• Remove the four screws that holds the fan housing
• Remove the junction box screw
• Remove 4 screws from the mounting bracket.
