9. USING OF THE ACCESSORIES
9.1 SOME EXAMPLES
In order to wash items in "LTC" or "STC" type
baskets, place the baskets on the "PS" (basic rack) or
"PSBT" (basic rack with spray arm) after removing one
or more "GS" (support grilles). Check that the basket is
correctly fitted on the rods of the rack designed for
that purpose. Reinstall the grids for any washing
operation that does not require the use of "LTC" or
"STC" type baskets.
Note : The "PST" should only be positioned at the
bottom level of the washer chamber where washing
action is provided by the lower spray arm. The "PSBT"
can be positioned on any level.
It is extremely important that the items to be washed
are prevented from moving in order to obtain correct
cleaning and to avoid breakage of fragile items. Items
that can be easily moved or knocked over when
loaded on the "PST" or "PSBT" rack should be
secured in place. The "GC" hold down screen should
be used for "PST" or "PSBT" racks. The "GCI" hold
down screen should be used for injector racks.
In the case of washing items with small diameter openings such as volumetric flasks, it is very important that the
flow rate of the injectors used must be lower than the flow capacity of the flasks to be washed in order to avoid
a gradual filling of the flasks during the washing cycle. If the diameter of the opening is too small to allow the
water to escape from around the injector the mechanical action of the injector can be absorbed by the water
contained in the glassware giving poor cleaning results. It is imperative to use baskets with injectors of proper
diameter and, above all, to secure lightweight items with a "GC" or "GCI" hold down screen.
