1. OPERATING INSTRUCTIONS

The operating instructions contain important information.

• Read the instructions carefully and follow the safety instructions
in particular.

• Keep the instructions in a location where they are available to
every user.

• The liability and warranty for Type 6628 are void if the operating
instructions are not followed.

2. INTENDED USE

The rocker solenoid valve Type 6628 is designed for analytical,
medical and laboratory applications. It is predominantly used to dose,
fill, mix, and distribute liquids and gases.

• Do not use Type 6628 outside without taking suitable protective
measures.

• Operate only when in perfect condition and pay attention to correct
storage, transportation, installation and operation.

2.1. Predictable Misuse

• Do not use Type 6628 in potentially explosive area.

• Do not make any internal or external changes to Type 6628.

3. BASIC SAFETY INSTRUCTIONS

These safety instructions do not make allowance for any contin­gencies and events which may arise during installation, operation
and maintenance.

WARNING!

Danger – high pressure!

• Before loosening lines or valves, turn off the pressure and vent
the lines.

Risk of burns/risk of fire if used continuously through hot
device surface!

• Keep Type 6628 away from highly flammable substances and
media and do not touch with bare hands.

• Do not obstruct the heat release required for operation.

To prevent injury, ensure the following:

• Secure equipment/device from unintentional actuation.

• Only trained technicians may perform installation and mainte­nance work.

• After an interruption in the power supply, ensure that the pro­cess is restarted in a controlled manner.

• Observe the general regulations of technology.

Electrostatic sensitive components/modules!

Observe the requirements in accordance with EN 61340-5-1 and
5-2 to minimize/avoid the possibility of damage caused by a sudden
electrostatic discharge!

5. INSTALLATION / DISASSEMBLY

5.1. Fluid Installation

WARNING!

Risk of injury from high pressure in the equipment.

• Before loosening lines or valves, turn off the pressure and vent
the lines.

Installation position: any position, preferably with actuator above.

→ Clean pipelines and flange connections.
→ Install dirt filter in the direction of flow in front of the valve (mesh

size 5 μm).

WARNING!

Risk of medium escaping if seal is seated incorrectly

• Make sure that the supplied seal fits properly.

• Use only connection plate of adequate quality and with a flat
surface.

→ Drill holes according to

Screws

drilling pattern
(dimensions see data
sheet).

→ Insert the seal into the

valve.

→ Correctly assign fluid

5.2. Electrical Installation

Electrical power supply: Tolerance ± 10 %
Permissible residual ripple: Tolerance ± 10 % of the nominal

voltage

Power consumption: 5 W

5.3. Disassembly

WARNING!

Risk of injury from hazardous media.

• Before loosening lines or valves, flush out hazardous media,
depressurize and drain the lines.
