Miele Laboratory Glassware Washer G 7883 - Manual (Page 23)

Loading the machine
– Always load items in a way that all
surfaces are exposed. This ensures
that the items will be properly
cleaned.
– Do not nest any items inside other
items. Keep each item separate.
– Hollow vessels must be arranged for
complete inside exposure to the
cleaning water.
– Hollow vessels should be inverted
and placed in suitable baskets and
inserts so that water will have
unrestricted access and exit.
– Deep-based items should be
arranged at an angle, so that water
can run off easily.
– Tall, narrow pieces should be placed
in the center of the basket for best
water coverage.
– Baskets and inserts with an adapter
must be properly connected.
– The spray arms must not be blocked
by items that are too tall or hang
through the baskets.
– To avoid corrosion, only load
stainless steel instruments in good
condition.
– Do not use this machine to wash
nickel-plated items or discolored
(oxidized) aluminum items.
– Do not load plastics unless they are
heat-resistant.
Prepare items before loading
^ Empty all glassware before loading
into the machine. Comply with all
applicable infection-control
regulations.
^ Remove all agar residue from petri
dishes.
^ Remove any blood clots and blood
residue.

sealing wax residue, etc.
,
Ensure that no acid or solvent
residues, especially hydrochloric
acid or chlorides, get inside the
machine.
Special preparations before
operating the machine
Items effected by heavy contamination
that resists removal, such as vacuum
grease, paper labels, etc., can affect
the cleaning and rinsing of the whole
load. Pre-treat these items before
loading.
Lab equipment that is contaminated by
microbiological material, pathogens,
propathogens, genetically altered
material, etc., may need to be sterilized
before being washed in the machine.
The user is responsible for this
decision.
