Step 2 (O-ring)
In case that you received the O-ring separately, 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 3 (tappet sealing)
Use MDT 328 - Tappet Sealing Changing Tool to press
the Tappet Sealing PE/PTFE/HT into the fluid box
body until it sits tight.
Step 4 (tappet centering piece)
Press the tappet centering piece into the fluid box
body. Use the wide end of the MDT 323 - Nozzle Insert
- Squeezing Out Tool TA. Make sure the tappet
centering piece rests flat.
Important note!
You do not need a tappet centering piece, if you use a
2G tappet rod.
Step 5 (tappet and tappet centering screw)
Screw the Tappet Centering Screw BY into the fluid
box. Do not screw it tight yet. Screw it only for two
rotations.
Important note!
Before mounting, please place a small droplet of
Tappet Grease TF (Order no. 1014637; droplet size ca.
2 mm) on the tappet and another on the tappet
spring (for placing see blue arrows in the picture).
Make sure that the tappet tip is free of grease. Rotate
the tappet and pull it in and out for three times to
spread the grease.
Place the tappet spring over the Tappet Centering
Screw BY.
Push the tappet rod through the tappet spring into
the Tappet Centering Screw BY. Make sure the tappet
goes through the tappet sealing.

Screw the Tappet Centering Screw BY completely into
the fluid box (torque 100 – 140 cN.m) with MDT 303 -
Nozzle Insert Changing Tool.
Make sure the three pins of the MDT 303 fit exactly
into the three holes of the Tappet Centering Screw
BY. Turn the MDT 303 clockwise while pressing it
down slightly to the fluid box.
Combine the MDT 303 with MDT 327 for a better
leverage.
Step 6 (nozzle insert)
Clip the nozzle insert into the fluid box. Use the small
hole of MDT 327 - Multi-Function Tool to pick up the
nozzle insert and to place it. Make sure the nozzle
insert sits flat.
Step 7 (nozzle fixation nut)
Screw the nozzle fixation nut clockwise onto the fluid
box. Use MDT 327 Multi-Function Tool.
Step 8 (cartridge base)
Place the cartridge base onto the fluid box and fix it
with the tightening screw. Screw the tightening screw
clockwise with MDT 327 Multi-Function Tool (torque
120 – 140 cN.m).
Important note!
In case you use a Cartridge Base without integrated
luer lock, you need to screw the Fluid Box Connector
Luer Lock into the top bore of the cartridge base CH.
Use the open-ended wrench of the MDT 327
(hexagon screw size M8, torque stainless steel 100 –
120 cN.m, PEEK 40 – 60 cN.m).
Optional (isolation body)
For thermally sensitive applications, you might use an
isolation body. Pull it onto the fluid box, until it clips
in. Screw it tight with the two screws for the isolation
body (torque 40 – 50 cN.m). Use the MDT 329 - L-
Shape hexagon Key 2 mm.
Step 9 (adjust screw)
Open the adjust screw completely. Screw counter-
clockwise. Use MDT 327 Multi-Function Tool.

Step 10 (fluid box)
Turn the locking lever by 180° from “Close” to “Open”
position.
Push the fluid box carefully in a 45° angle onto the
valve.
Straighten the fluid box and close the locking lever.
Optional positions
The bayonet fluid box has three different locking
positions (1: 90°, 2: 0°, 3: +90°) in which the valve can
be operated. To fix in locking position 1, mount the
fluid box at position a. To fix in locking position 2 or 3,
mount the fluid box at position b.
Step 11 (cartridge holder)
Screw the cartridge holder on top of the valve body
(torque between 40 – 50 cN.m). Use the MDT 329 or a
hexagon socket key size 2. Depending on the size of
the cartridge, you have to select the correct cartridge
holder. Hook the heater connection of the fluid box
into the cartridge holder (see blue arrow).
Step 12 (cartridge)
Push the cartridge through the cartridge holder and
screw it clockwise into the thread of the cartridge
base.
