Afterwards, use a fluid box cleaner. Check all bores
as well and then clean the rest of the fluid box
body.
Step 4 (cartridge base)
For the cartridge base, start with the fluidic brush
to clean all bores and openings of the cartridge
base.
Next clear the bore with a cleaning rod.
Finally use a fluid box cleaner to clean the wide
opening of the bore.
Important note!
If you use a cartridge base without integrated luer
lock, you need to clean the Fluid Box Connector
Luer Lock as follows. Otherwise, you can continue
with the next step.
Push a cleaning rod through the bore of the Fluid
Box Connector Luer Lock several times to remove
any residues of the medium.
Clean the center bore of the Fluid Box Connector
Luer Lock using a fluidic brush.
Clean the openings and thread of the Fluid Box
Connector Luer Lock using a fluid box cleaner. Use
it for the outside and the end of the bore.
Step 5 (tappet sealing)
For the tappet sealing, clean the bore of the tappet
sealing carefully with a fluidic brush.

Afterwards, clean the outside of the tappet sealing.
Keep using the fluidic brush, especially for the
outer edge.
Then clean the inner rim of the tappet sealing with
a cleaning rod.
Clean the outside of the tappet centering piece
first with a lint-free cloth.
Use a fluidic brush for the bore of the tappet
centering piece.
Important note!
There is no tappet centering piece, if you use a 2G
tappet rod.
Step 6 (valve body)
Clean the valve with a lint-free cloth.
Step 7 (O-ring)
Clean all O-rings with a lint-free cloth.
Tab. 30: Clean all components by hand
– Dry all the components in the air or with compressed air. For nozzle inserts we recommend to
use the MDT 324 Nozzle Insert Cleaning Holder.
INFORMATION
A two finger seesaw test is necessary to check if the tappet rod runs smoothly through the tappet
centering screw. Otherwise, the parts have to be cleaned again.
In case you still have parts which are not completely clean after the fine purification, repeat the
corresponding cleaning steps for those components several times, if necessary. If that is still not
helping, contact our Technical Support.

9.4.5 Assembling of the Fluid Box and the Tappet
Re-assemble the valve and its components as follows.
Unusual (connector BY)
In the exceptional case that you removed the
connector BY as well, you have to mount it first.
Place the fluid box body on the receptacle of the
mounting body. Align the bore on the fluid box
body with the bore on the mounting body (see
circles). The fluid box body will fit into the mounting
body, if the mounting direction is correct.
Push the Connector BY through the mounting body
into the bore of the fluid box body. Screw the
Connector BY tight (clockwise) by using an MDT 327
(for newer revisions of the Connector BY you can
also use a hexagon key 2.5 or the Torque Wrench
Tool VM with the Bit Hexagon Key 2.5). Torques are
depending on the material of the mounting body
(stainless steel 90 – 100 cN.m, PEEK 70 – 80 cN.m).
Important Note!
Do not press the fluid box body while fastening the
Connector BY, otherwise, it cannot correctly grip
into the fluid box body.
Step 1 (O-ring)
In case that you removed the O-ring, you have to
mount it onto the fluid box body.
Pull the O-ring over the fluid box body with a pair of
tweezers. Be careful not to damage the O-ring.
Step 2 (tappet sealing)
Use the MDT 328 - Tappet Sealing Changing Tool to
press the Tappet Sealing PE/PTFE/HT into the fluid
box body until it sits tight. When the tappet sealing
sits tight, you will hear a light noise.
Step 3 (tappet centering piece)
Press the tappet centering piece into the fluid box.
Use the MDT 328 to make sure the tappet centering
piece rests flat on the tappet sealing.
Important note!
When using a 2G tappet rod, do not use a tappet
centering piece.
