MAINTAINANCE AND
CLEANING
STERILISER CLEANING
Water quality and a clean chamber are vital to the correct
operation of the system.
The chamber and all wetted parts should be cleaned
regularly in order to maintain adequate operating
conditions. Load containers should be chosen to minimise
loss of the contents into the steriliser, e.g. ideally do
not use plastic bags inside steriliser baskets but use a
purpose-made steriliser container designed to catch
leaking waste. Please ask your supplier for details of
containers for your machine.
CHAMBER CLEANING
The chamber should be cleaned internally to prevent
build-up of contaminants, and we would suggest that
for a machine in daily use. The chamber should be
checked once a week and cleaned if necessary. For other
applications cleaning should be at monthly intervals or
more frequently if needed.
• Open the door as normally
• Remove all trays or shelves
• Clean the base of the chamber with hot water. Do
not use an abrasive cleaner or one which may leave
soluble residues that would remain in the pipework and
contaminate the water
• Take care not to damage the sensors, or to displace
them in any way
• Wash the sensors with hot water and a soft cloth. Rinse
if required with clean warm water
• Dry the chamber with paper or cotton towels. Do not
leave fragments of paper or lint behind
• Wipe the gasket with a wet cloth moistened with a little
detergent
• Do not use chlorine bleach cleaners inside the stainless
steel chamber. Water and detergent should be
used to wash the chamber out when required, and a
“scotchbrite” scouring pad may be used carefully. Do
not damage the gasket or the gasket mating surface
Limescale in chamber
Where limescale has built up you may use an acid-free
kettle descaler or bathroom limescale remover type of
product to dissolve the limescale but please ensure this
does not contain bleach.
CABINET AND GENERAL CLEANING
•
Cabinet stainless steel and painted surfaces:
The cabinet surfaces may be cleaned with a damp cloth
moistened with water and a little household detergent
or detergent based non-bleach spray cleaner
• Do not use abrasives or chlorine-based cleaners or
bleaches on the cabinet or chamber and do not spray
cleaners directly onto cabinet surface
• If stubborn marks persist use a soft cloth moistened
with a very small amount of methylated spirits. Do not
use IPA or similar solvents or aqueous cleaners, as
these will damage the transparent window
•
Touchscreen and control panel:
Clean with a cloth moistened with a little water.
Alternatively you can use spectacle cleaning wipes
suitable for plastic lenses
•
Labels
(e.g. on panel work) for printed labels on the
panels wipe gently with a cloth moistened with a little
water and optionally a spot of detergent. Do not rub
hard, use solvents or abrasives or you will destroy the
printing
•
Working parts
to clean, steel, brass, aluminium parts
etc., or other working parts use a soft cloth moistened
with “WD40” or “duck oil” or similar. If that is not
available, use a little white spirit / turpentine. Do not
use other solvents such as IPA (rubbing alcohol), or
strong aqueous cleaners
