5.5 Cleaning Regime
A typical cleaning regime consists of five stages:
1. Pre-Rinse
2. Detergent Rinse
3. Rinse
4. Disinfectant Rinse
5. Final Rinse
Never immerse the Pneumatic Actuator as it will cause permanent internal
corrosion.
5.6 Cleaning Solutions
Detergents are typically alkaline solutions. Disinfectants typically contain Chlorine 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 will reduce / eliminate microbiological 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.
Information about IP69K rating relates ONLY to an IQ3X Rectangular Head, NOT the
conveyor system.
Both the Standard and Harsh versions of the metal detector have been designed and tested to
meet IP69K water pressure between 1160 - 1450 psi @between 3.69 - 4.2 gallons per minute @ 80
centigrade.
Water is sprayed @ a distance between 3.9 - 5.9 inches @ angles of 0, 30, 60 & 90 degrees for 30
seconds @ each angle. Nema equivalent is PW12 which is slightly less rigorous.
Prior to starting cleaning procedures ensure that the head control panel cover fixing
screws have been tightened to 4Nm torque to maintain the integrity of the IP69K
rating for the head; preventing ingress of water or condensation.
