Steps to ensure safety and
prolong performance during inactive periods

Sometimes your equipment need to be stopped for long periods of time.  Electrolux Professional wishes to provide you with some measures that will prolong the life of your machines and ensure they will be kept to their top performances and safe to use again in the future.

ATTENTION
Before carrying out any operation, remember to wear suitable PPE (personal protective equipment) such as: glasses, masks, gloves, safety shoes, suitable work clothes, etc.
In case of doubt, please refer to your local Electrolux Professional service agent: they will be happy to support you.

A. Idle preparation:

• Clean all surfaces from dust, debris and grease. Avoid using detergents containing abrasive substances, steel wool, brushes or steel scrapers
• Once the surfaces are clean, protect all stainless-steel surfaces of tables, neutral surfaces, storage and preparation areas with a thin layer of petroleum jelly in order to preserve the integrity of the material.
• Whenever possible, cover with a plastic sheet to avoid accumulation of dust, making sure it doesn’t stick to the surface, so that no crevice corrosion is triggered

B. Recovering from idle:

• Clean all surfaces from the protective film, then sanitize all the surfaces which could be in contact with foodstuffs. Caution: chlorine-based products are sanitizing but alter the protective layer of the stainless steel and shall not be used.
• It is recommended to use dedicated products based on hydrogen peroxide or quaternary ammonium. Ethanol with biocidal properties can also be used.
• After the sanitization thoroughly rinse with water and a damp cloth and carefully dry all stainless steel surfaces in order to prevent oxidization.
• In case the surfaces were not properly cleaned before the idle time, refer to the instructions provided above.
• Remember to ventilate the premises during these actions.

A. Idle preparation:

• Thoroughly clean burners, trivets and surfaces with a damp cloth. Make sure the cloth doesn’t leave any lint.
• Carefully clean the tip of thermocouples with a brush with no metal bristles.
• Take high care preventing gas nozzles to get blocked or clogged.
• Clean and dry oven chamber – leave oven door ajar to allow air to circulate inside, unless there is a risk of dust, insects, pests, etc. getting into the cavity.
• Close any gas valves and isolate gas supply at the nearest isolation point.

B. Recovering from idle:

• Open the gas valves.
• Check the flames consistency (max, min) per each burner.
• Ovens: before operating, check any presence of vermin and act accordingly.

A. Idle preparation:

• In case of sticking residues, gradually increase the temperature to the maximum possible in order to cause pyrolysis of these. Once charred and the element temperature has dropped, use hot degreasers such as C40 Degreaser (code 0S1841), which works at 175 °C or at a lower temperature with a soft cloth and lukewarm soapy water.
• If necessary, use a scraper: starting from the furthest part of the surface, pull the scraper towards you, removing any sticky deposit. Be careful not to damage the surface.
• The use of cold water or ice cubes is strictly prohibited, as it would cause a thermal shock and damage your cooking elements.
• Empty and clean any grease/dirt collecting drawer, basin or bucket.
• For direct cooking surfaces (such as griddle, braising pan), once the surfaces have been degreased and washed, heat up for at least 5 minutes to dry them, then switch off the heating and coat them with a thin film of vegetable oil.
• Where possible, lift hob and clean underneath.

A. Recovering from idle:

• Electrical heated equipment: set the power/temperature at the minimum for at least 1 hour to prevent electric heating elements fault due to possible accumulated humidity.
• In case surfaces were not properly cleaned when stopping activities, first carry out the operations as per the ‘Idle preparation’ section.
• Cooking surfaces does not need sanitization with chemical agents as the working temperatures provide the same effect: remember, before carrying out the first cooking, heat up at max power for some minutes.
• On direct cooking surfaces, renovate the vegetable oil coating.

A. Idle preparation:

• Drain any oil from tanks in all cases and have it disposed through the usual recycling channel. It is recommended not to filter it for reuse, in particular because of the concentration of acrylamide and release of ketone and aldehyde (oxidation of oil and absorption of moisture).
• Fill tanks with water and 10% vinegar, then pour some spoons of baking soda; fierce boil some minutes for an effective cleaning. The following draining will also degrease and clean hoses, taps, buckets and oil filtration systems.
• Once cleaned, carefully dry any surface.
• Clean any baskets, detachable basket supports, etc. in a dishwasher.
• Finally, put the basket(s) in the tank and cover with the lid (where available).

B. Recovering from idle:

• Electrical heated equipment: set the power/temperature at minimum for at least 1 hour to prevent electric heating elements fault due to possible accumulated humidity.
• In case oil was not drained from the tanks before stopping activities, first carry out the operations as per the ‘Idle preparation’ section. WARNING for solid oil/grease (like palm oil): melt oil down for draining it, as heating up normally might provoke the oil to take fire.
• Before operating, check any presence of dust, insects, pests, etc. and act accordingly.

A. Idle preparation:

• Wait for the tanks and the residual water to cool down, then completely drain them. Do not drain water from pasta cooker if hot: failure to follow this indication may damage the tank. Descale any limestone deposit with a suitable product (or hot white vinegar). Check the condition and the presence of seals on the drain plugs. Remove debris, then rinse and dry all stainless steel surfaces finally protecting them as per the section “Stainless steel – painted / coated surfaces – equipment in general” indications.
• Close any water supply valve.

B. Recovering from idle:

• Open water supply valves and fill tanks before any switch ON (failure to follow this indication might damage the tank).
• Electrical heated equipment: set the power/temperature at minimum for at least 1 hour to prevent electric heating elements fault due to possible accumulated humidity.
• In case the water was not drained at the time of the idle preparation, follow the relevant indications.
• Before restarting to work, it is recommended to carry out the sanitization operations like reported in the section “Stainless steel – painted / coated surfaces – equipment in general”.

A. Idle preparation:

• Check if any visible water leakage from underneath (in case, a specialized engineer is required).

A. Idle preparation:

• Carry out full cleaning as per weekly routine, including the daily cleaning plus the extra-operations to be performed every week. Use the detergent C41 – code 0S2292 (which works at 175 °C or at a lower temperature)- allowing to soak for 1 minute.
• All parts (including the working top, the glass, the upper plate, the cooking chamber, the choke cover and the steam exhaust chamber) need to be clean and thoroughly degreased: disassemble the parts according to the user instruction manual. After cleaning the glass, protect it with the “high temperature silicone pad” (code 653527).
