Operating Instructions

The SUN AIR exhaust hood is designed to effectively remove grease-laden vapors, smoke, and heat from your commercial cooking area. Proper operation ensures a safe and comfortable working environment.

General Operation:

1. Power On: Activate the exhaust fan system and hood lights before commencing any cooking operations.
2. Fan Speed: Adjust the fan speed as needed to effectively capture and remove cooking effluents. Higher heat and grease production may require higher fan speeds.
3. Monitor Performance: Regularly observe the hood's performance to ensure adequate capture and containment of smoke and vapors.
4. Power Off: After cooking operations are complete, allow the fan to run for a short period to clear any residual smoke or odors before powering down.

Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your exhaust hood, as well as for fire safety. Adhere to a strict cleaning schedule.

Cleaning Procedures:

• Grease Baffle Filters: Remove and clean the stainless steel grease baffle filters regularly (daily or weekly depending on usage). They can be washed with hot soapy water or in a commercial dishwasher. Ensure they are completely dry before reinstallation.
• Grease Cup: Empty and clean the grease cup frequently to prevent overflow and fire hazards.
• Hood Interior and Exterior: Wipe down the interior and exterior surfaces of the hood with a mild detergent and a soft cloth. Avoid abrasive cleaners that can scratch the stainless steel finish.
• Light Fixtures: Clean the high-temperature light fixtures as needed. Ensure power is off before cleaning or replacing bulbs.
• Ductwork: Regular inspection and cleaning of the exhaust ductwork by a certified professional is recommended to prevent grease buildup, which is a significant fire risk.
