Frequently Asked Questions - COS-668WRC90 Cosmo
How do I install the Cosmo COS-668WRC90 range hood?
The manual provides detailed installation instructions. Generally, you need to mount the chimney to the wall, connect the duct to the outside, and wire the hood to a grounded 120V outlet. We recommend a professional installer for safety.
How often should I clean the aluminum mesh filters?
For optimal performance, clean the filters every month. They are dishwasher-safe; simply remove and wash. Let them dry completely before reinstalling.
Can I use this range hood in recirculation mode?
Yes, the hood can be used with a charcoal filter (not included) for recirculation when ducting is not possible. Follow the manual to install the optional charcoal filter.
What is the warranty period?
Cosmo offers a 1-year limited warranty covering manufacturing defects. Parts and accessories are covered separately. Contact technical support for details.
How do I replace the LED lights?
Turn off the power, remove the light cover, and detach the LED module. Replace with an identical LED module (available from Cosmo) and reinstall.
Why is the motor running but there is no suction?
Check if the duct is blocked or the filter is clogged. Also ensure the backdraft damper is open. Clean or replace filters if needed.
What duct diameter is required?
The exhaust outlet is 150 mm (6 inches). For best airflow, use a rigid or flexible duct of the same diameter with minimal bends.
How do I select different fan speeds?
Use the push buttons on the control panel. Typically, the low/medium/high speed buttons control airflow intensity. Press the same button again to turn off.
Are the filters dishwasher-safe?
Yes, the aluminum mesh filters can be placed in the dishwasher. Use a gentle cycle and avoid high heat drying to prevent warping.
