Checking other vertical pumps for leaks
Use this procedure to test for leaks from other vertical pumps: the sampling wash pump
(SCP), dilution wash pump (DCP), dilution discharge pump (DOP), reagent dispensing
pumps (RP1 and RP2), and reagent wash pumps (RWP1 and RWP2).
1. To determine if any of these pumps are leaking, inspect the upper portion (1)
(cylinders, L-ring holders, tubes and fittings) of the vertical pumps.

2. If the pump is leaking, you must replace the pump seal. To replace the pump seal,
call your local technical support provider or distributor.
