Cleaning & Maintenance »

The Midtherm canopy range is designed to provide a long-lasting, high quality finish and high performance grease extraction. To ensure the system continues to extract grease safely whilst maintaining an hygienic, corrosion-free finish, it is essential that regular maintenance procedures be implemented.

Canopies

Canopies require bi-annual inspection to ensure trouble-free operating. All grease drain points should be checked for blockages and cleaned as required. Grease collection trays should be emptied as required.

Filters

All filters are provided with grips for easy removal and insertion. Appliances should be isolated before cleaning to avoid unfiltered air entering the system and depositing grease (causing a potential fire hazard). Depending on cooking load, filters should be cleaned regularly to ensure optimum working conditions. It is recommended that the filter and collection drawers are cleaned once a week to prevent accumulation of dirt, grease, grit, etc. Both mesh and baffle type filter cells are sized to facilitate their cleaning with any commercial dishwashing machine. Alternatively, soaking for 15 minutes in a warm degreasing agent can also clean mesh-type filters. DO NOT USE AGGRESIVE CLEANING SOLUTIONS.

Fans

Check fans regularly for undue noise or vibration. Cleaning the fan impeller often cures any vibration. Always ensure the electrical supply has been isolated before carrying out any inspection work on the fan. Check that the flexible couplings, where fitted, are secure and undamaged. Fan motors with grease fittings should be lubricated using a low pressure grease gun with shell alvania no. 3 grease.

Ducts

An annual inspection should be carried out to ensure there is no accumulation of congealed grease in the ductwork. The HVCA recommended cleaning periods for extract ductwork is either 3 Monthly (Heavy Use: 12-16 hours per day), 6 Monthly (Moderate Use: 6-12 hours per day) or Annually (Light Use: 2-6 hours per day).

UV Filtration

The incorporation of an Ultra-Violet Filtration system in a kitchen canopy set-up can reduce or remove common issues associated with kitchen extract systems, ie. the build up of grease creating a fire risk or the nuisance of odours from kitchen environments.

UV Filtration works by using UVC lamps to break down organic material by a combination of photolysis and ozonolysis and destroys odours more efficiently and cost effectively than conventional filtration systems.

Advantages of UV Filtration »

• Drastically reduces airborne grease particulate
• Destroys cooking odours
• Reduces fire risk in ductwork
• Works automatically
• Helps protect downstream plant, filtration and heat exchangers
• Potential for low level discharge
• Lower operating costs compared with carbon based systems
• Reduces ductwork cleaning
