consult our Technical Support at once (see Page 7). Do not start the system in incomplete state.

6.2 First Assembling of the Valve

This chapter describes how to ready your microdispensing system for the first dispensing session.

Always make sure all screw couplings sit tight (torque values in paragraph 3.3.11, page 19).

INFORMATION

Some parts preassembled

Some elements of the equipment are usually delivered in preassembled state. In those cases, you

can omit the respective steps.

Proceed as follows:

Picture Explanation

Step 1 (fluid box body)

Information!

This step will be optional, if you re-assemble the

valve later, since usually you would not remove

the Connector BY from the mounting body.

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 in the first picture). The fluid box body will

sit in the mounting body.

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 MDT

306 - Torque Wrench Tool VM with the Bit

Hexagon Key 2.5). Torques are depending on the

material of the mounting body (stainless steel 120

– 140 cN.m, PEEK 70 – 80 cN.m).

Important Note!

Do not press the fluid box body while fastening

the Connector BY. Otherwise, the Connector BY

cannot correctly grip into the fluid box body.

Step 2 (O-ring)

Pull the O-Ring-BY over the fluid box body.

Step 3 (cartridge base)

Mount the cartridge base onto the fluid box. Use

MDT 327 or the MDT 306 - Torque Wrench Tool

VM with BitVM-A to fix the cartridge base with the

tightening screw by screwing clockwise (torque

110 – 120 cN.m).

Important Note!

There are two types of cartridge base: Cartridge

Base CH (without integrated luer lock) and

Cartridge Base CHI (with integrated luer lock). If

you use a Cartridge Base CH, 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).

Step 4 (tappet sealing)

Push the tappet sealing with the wider side down

onto the pin of an MDT 328. Push the MDT 328

with the tappet sealing straight into the fluid box.

When the tappet sealing sits tight, you will hear a

light noise.

Step 5 (tappet centering piece)

Press the tappet centering piece into the fluid box

body. Use the MDT 328 to make sure the tappet

centering piece is lying straight on the tappet

sealing.

Important Note!

When using a 2G tappet rod, you do not need a

tappet centering piece.

Step 6 (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.

Push the tappet rod with the tappet spring

slightly into the tappet centering screw. Place a

small droplet of Tappet Grease TF (Order no.

1014637; droplet size ca. 2 mm) on the tappet and

another on the tappet centering screw (for

placing see blue arrows in the picture). Make sure

that the tappet tip is free of grease. Rotate the
