Replacing the dispensing cartridge

1. Completely unscrew the safety ring of the dispensing cartridge by

hand and remove the dispensing cartridge.

2. Screw the new dispensing cartridge into the valve block and tigh-

ten the safety ring by hand.

3. Carry out a function check for leaks.

Discharge valve

1. After disassembling the discharge tube (see 'Replacing the

discharge tube', page 43), use the mounting tool to unscrew the
discharge valve (Fig. 1).

2. Screw in the new discharge valve first by hand, then tighten it

securely with the mounting tool (the threads should no longer be
visible).

Note:

A function test must always be carried out after dismantling.

Caution:

Always install the valve provided for the specific instrument types
(see 'Ordering data', page 46). For the VITLAB

®

Dispenser TA

2

model, an identical filling valve is used, but different discharge
valves. To distinguish between them, the discharge valves of the
VITLAB

®

Dispenser TA

2

are marked 'Pt-Ir' or 'Ta'. Be sure that only

the filling valve specified for the VITLAB

®

Dispenser TA

2

with mark-

ing 'S' (sapphire) is used.

15. Dismantling instrument

Caution:

The valve, telescoping filling tube, dispensing tube, and recircula-
tion valve and recirculation tube if present, are full of reagent! For
this reason, always perform a standard cleaning before dismantling
the instrument. Follow the safety instructions (page 28)!

Note:

The dispensing cartridge has been calibrated at the factory. Thus,
calibration after replacement can be omitted.
Rinse the instrument thoroughly before use, and discard the first
sample dispensed. Avoid splashes.
Depending on the application requirements, cleaning for trace
analysis is to be carried out (page 42).
The dispensing unit must not be disassembled!
