Connect the drain hoses to the connections marked for chromate waste, rinse waste and
emergency overflow.

Route the drain hose for dichromate waste into the cover of the canister and make sure the
drain hose for the rinse water and that for emergency overflow end in the drain pipe previously
laid. The drain hose for emergency overflow must be open to air. Avoid siphon formation at all
times!

Insert the valve hoses accordingly. These were partly removed from the valves for
transportation. This prevents the hoses from sticking or pressure being applied to a point in the
hose over an extended period.
9.
Secure the hose boxes in the appropriate pump holders:
Sample/acid pump, left (rear position), reagent pump, right (center position). The direction of
flow of the sample and reagent must be counterclockwise.
