1.4 Instrument Rack
• Prerequisite for an effective machine
cleaning is appropriate and rinsing
oriented loading of the racks.
• Articulated instruments must be open.
• The sieve trays must not be over-
loaded.
• The spray arms must be able to al-
ways freely rotate
• Large surface instruments must
placed on sieve trays that they do not
encumber the cleaning of other in-
struments with their spray shadow.
• Components of motor system may
only be machine processed if the
manufacturer has approved such han-
dling in connection with special proce-
dures and retainer equipment. Simple
tools and accessories may be proc-
essed just like surgical instruments.
1.5 AN Rack
Inappropriate loading (improperly placed) anes-
thesia hoses may tear loose from their retainer
and thus impede the wash arm in its rotation.
The disconnected respiration hose will thus be
inadequately rinsed and will remain unclean.
The drying process is prolonged, is delayed if
water remnants found in water sacks of hoses
cannot be drained
Effect of rack loading characteristics on dryer performance
Critical areas such as flanges of containers, OP shoe heels, water sacks in hoses, turned over bowls, im-
permeable hollow places of instruments, where water remnants cannot be completely drained and hence
must be evaporated.
