How to Install and Maintain a Commercial Kitchen Electrostatic Smoke Filter?

The installation and maintenance of a commercial kitchen electrostatic smoke filter directly impacts its purification efficiency, service life, and safety. The following are detailed installation and maintenance procedures to help restaurant operators implement standardized procedures:

I. Installation Steps for a Commercial Kitchen Electrostatic Smoke Filter

1. Pre-Installation Preparation

Site Survey: Confirm the installation location and ensure adequate space, good ventilation, and convenient connection to the oil smoke duct.

Equipment Inspection: After unpacking, inspect the purifier and accessories to ensure they are intact. Verify that the device model and air volume match the exhaust duct size. Tool Preparation: Prepare a power drill, wrench, sealant, and fireproof cotton. If wiring is required, perform the installation by a licensed electrician.

2. Specific Installation Procedure

Securing the Equipment:

Mount the purifier horizontally on a stable bracket or wall. Secure it with expansion screws to ensure it does not wobble during operation.

Connecting the Exhaust Duct:

Connect the purifier's air inlet to the stove hood duct, and the air outlet to the fan duct. Seal the joints with sealant or fireproof cotton. If the duct is too long, add brackets in the middle to secure it.

Electrical Connection:

Connect to a power source that meets the specifications according to the manual. Install a leakage protection circuit breaker. Ensure the ground wire is securely connected (to prevent the risk of electric shock).

Fan Matching:

The fan should be installed behind the purifier's air outlet, and the fan's air volume should be slightly larger than the purifier's (to ensure that all cooking fumes enter the purifier to prevent backflow). Commissioning and Operation:

After powering on, check whether the device starts up normally (e.g., the sound of electric field discharge and the status of the indicator lights). Run for 3-5 minutes and observe whether the exhaust is smooth and whether there are any abnormal noises or oil leaks. If any abnormalities are detected, immediately stop the device and inspect.

II. Maintenance Methods for Commercial Kitchen Electrostatic Smoke Filters

1. Daily Inspection

Before starting the device, check whether the power supply is normal, whether the wiring is loose, and whether the connection between the purifier and the pipe is tight.

During operation, observe the device for any unusual noises or odors, and whether there is any noticeable oil smoke overflowing from the exhaust vent (if any, it may be a clogged filter or electric field failure).

After shutting down, inspect the device for any oil dripping from the body and clean the surrounding area promptly to prevent oil accumulation and fire.

2. Regular Cleaning

Cleaning Frequency:

For locations with high oil smoke production: Clean every 15-30 days;

For locations with low oil smoke production: Clean every 1-2 months.

Cleaning Procedure:

Disconnect the power supply and wait for the device to cool. Disassemble and clean components such as the filter, electric field, and oil collection tray (refer to the manual to avoid damaging components through forceful disassembly).

Cleaning Method:

Filter/Oil Collection Tray: Soak in hot water and a neutral detergent for 30 minutes. Remove any oil residue with a soft brush. Rinse, let dry, and reinstall.

Electric Field: Spray with a special detergent, let it sit for 10 minutes, then rinse with a high-pressure water jet. After drying, check that the electrodes are aligned and free of oil residue.

Internal Cleaning:

Wipe the purifier's internal casing with a damp cloth to remove any accumulated oil and ensure there is no accumulation of oil.

Reassembly:

Install components in the reverse order of disassembly, ensuring that the interfaces are sealed and the electrical connections are secure.

3. Regular Maintenance

Electrical System: Check the power cord, plug, and switch for aging, and the electric field terminals for looseness or oil accumulation. Ensure proper insulation.

Fan and Ducting: Clean any accumulated oil in the exhaust duct. Check the fan impeller for balance and the belt for looseness to avoid overloading the purifier due to duct blockage. Core Components: For electrostatic purifiers, check for deformation of the electric field and broken electrode pins. For filter-type purifiers, check the filter for damage and replace it promptly if any.

4. Special Situation Handling

If the purifier suddenly shuts down, first check the power supply and leakage protection circuit breaker. After eliminating any circuit faults, check whether excessive oil contamination has triggered the overload protection.

If purification performance is significantly reduced (thick smoke coming from the exhaust vent), this may be due to a clogged filter/electric field, insufficient fan airflow, or an incompatible device model. Targeted troubleshooting is required.

III. Maintenance Precautions

Safety First:

Always disconnect the power supply during cleaning and maintenance. Do not directly rinse live parts with water. Regularly check that the equipment is properly grounded to prevent static electricity from causing fires.

Use Approved Cleaning Agents:

Avoid using strong acids or alkalines to clean the electric field or filter to prevent corrosion. (Specialized fume cleaners are recommended.)

Maintain a Maintenance Log:

Record the time, content, and abnormalities of each cleaning and maintenance to track equipment status and identify potential problems.

Replacing Consumables:

When consumable parts such as filters and sealants reach the end of their lifespan, they should be promptly replaced with genuine parts to minimize degradation in purification performance.
