Maintenance
Do not hose wash UL approved controls; use only a light hand wash and wipe dry
procedure.
Cleaning regime
A typical cleaning regime consists of the 5 stages.
• Pre-rinse
• Detergent rise
• Rinse
• Disinfectant rinse
• Final rinse
Cleaning solutions
Detergents are typically alkaline solutions with a PH value of 5 to 6. Disinfectants typically
contain Chorine or Ammonia. Every 3-4 weeks it is typical to revert to acid based cleaning
solution to remove any build up of lime scale on stainless steel parts.
For specific cleaning applications please refer to the supplier of the cleaning solutions.
Always observe safety data sheet provided by the manufacturer of the cleaning solutions.
If chlorine based cleaning solutions are used on grade 304/304L stainless steel there is a risk
of corrosion appearing within a short time. A higher specification 'marine grade' 316
stainless offers more resistance to corrosion by virtue of its molybdenum content.
Cleaning in accordance with the individual system paragraphs will reduce/eliminate micro-
biological contamination to an acceptable level. Prior to a production run a swab test should
be carried out to ensure that the required level of hygiene is maintained for food production.
If a hose wash is to be used the maximum safe wash down conditions are as follows:
• Water jet nozzle is < 12.5mm (1/2") diameter.
• Water delivery rate is <105 litres/minute (23 gallons/minute).
• The distance of the nozzle from the equipment is 2.5 - 3.0 meters (8.0 - 10 feet).
• Never direct water into bearings.
Cleaning
Belt conveyor versions
• Isolate the electrical and pneumatic supplies to the conveyor.
• If your conveyor system uses a harsh construction search head (white plastic liner) then
hose down or steam cleaning can be used in place of washing with mild detergents.
