Machine installation diagram

 

  1. Power connection
  2. USB cable
  3. Pneumatic hose
  4. Suction unit
  5. External compressed air supply
  6. Data cable of supported suction units (optional)
  7. Control cable of the switching unit (optional)
  8. Suction hose
  9. Switching unit (optional)

You can either use the switching unit including the control cable or the data cable of supported suction units. The data cable must be provided by the manufacturer of the suction unit.

Establishing the electric connection

The machine requires an uninterruptible power supply for proper operation.

  1. Plug the provided power cable into the mains connection on the connection panel of the machine.

  2. NOTICE! To avoid job interruptions, install an uninterruptible power supply (UPS), type online / VFI (IEC 62040-3, Class 1) if there are regular power failures or frequent mains voltage fluctuations.

  3. Insert the plug of the cable into a socket that is protected by a Residual Current Device / Ground Fault Circuit Interrupter.

Installing the pneumatics

You can find specific values and additional requirements in the chapter on technical data. Technical data

The machine requires the compressed air for the following tasks:

  • For the opening and closing of the collet chuck during tool changes.
  • For the spindle sealing air which prevents foreign bodies from entering the spindle.
  • For the sealing air in the working chamber that keeps machining debris away from sensitive machine parts.

Overview compressed air regulator

The machine is connected to the external air supply via a compressed air regulator. You can use this regulator to monitor and regulate the pressure of the incoming air.

The compressed air regulator is supplied with the machine and needs to be mounted on the side of the machine housing when installing the machine. The regulator has the following connections:

  • 1/8” internal thread, fitted with male compressed air connector to connect the external compressed air supply
  • 6 mm push-in fitting to connect the machine.
NOTICE

Failure of the water separator caused by a wrong alignment of the compressed air regulator

The compressed air regulator must always be mounted in an upright position because otherwise the water separator will not work.

  • Mount the compressed air regulator in an upright position.

On the left side of the machine are 2 drill holes that you can use to mount the compressed air regulator on the machine.

  • Mount the compressed air regulator in an upright position, using the oval-head screws provided in the drill holes.

 

Installing the pneumatic hose

 

  1. Close the main external compressed air supply valve.
  2. Use the provided pneumatic hose to connect the right pneumatic connection of the compressed air regulator to the pneumatic connection of the machine.
  3. Connect the external compressed air supply to the left pneumatic connection of the compressed air regulator.
  4. Thoroughly verify that all external pneumatic hoses are properly seated in their corresponding connections and that the hoses and connectors are undamaged.
  5. If all hoses and connectors are properly installed and undamaged, open the external compressed air supply valve.

Adjusting the air pressure with the compressed air regulator

Setting the air pressure is only necessary if the air pressure shown by the pressure gauge does not lie between the minimum and maximum air pressure. You can find specific values and additional requirements in the chapter on technical data.

 

  1. Rotary knob for pressure regulation
  2. Pressure gauge for monitoring the outgoing air pressure
  3. Bowl of the water separator
  4. Discharge screw

  1. Pull the rotary knob on top of the compressed air regulator slightly upwards.

  2. Turn the rotary knob in the desired direction:
    • Turn it in the “+” direction to increase the pressure
    • Turn it in the “-” direction to decrease the pressure
  3. Push the rotary knob down again.
    • The knob is locked and cannot be changed inadvertently.

Requirements for the suction unit

You can find specific values and additional requirements in the chapter on technical data. Technical data

  • Use a suction device with the following properties only:
  • Designed for the commercial use in the dental sector
  • Equipped with a filter of the filter class M
  • Equipped with safety devices which protect you from static discharges (e. g. through an anti-static suction hose)

Installing the suction unit

You can install the suction unit as follows:

  1. Read the documentation for the suction unit. Follow the operating and safety instructions at any time.

  2. Check if the connection of the suction hose has an outer diameter of 45 mm.

     

  3. If the diameter is different, adjust either the hose or the hose adapter supplied with the suction unit.

    Alternative: Use the optional hose connection of vhf.

    Example: Suction hose with hose adapter

    or

    Hose connection

  4. Insert the suction hose into the opening for the suction unit on the machine. Make sure that the suction hose is properly seated.

    5.  

  5. Continue with the installation of the suction unit as described in the documentation of the unit.

If you cannot connect the suction hose of the suction unit directly to the machine, install the hose connection as follows:

  1. Obtain the hose connection from customer service.
  2. Turn the thread of the hose connection counterclockwise until the connection is completely open.

    3. If the thread gets detached from the hose connection, place it onto the connection again and turn it clockwise once so that it is screwed to the connection again.

  3. Insert the suction hose of the suction device completely into the hose connection on the side of the thread.

    4.  

  4. Turn the thread of the hose connection clockwise as far as you can.
  5. Insert the hose connection into the opening for the air extraction system of the machine. Ensure it is firmly connected.

 

Installing the switching unit

If you want the machine to automatically switch the suction unit on and off, but a data cable is not available, you can use the optional switching unit. The switching unit is not available worldwide.

  1. Connect the power cable of the suction unit to the switching unit.
  2. Connect the control cable of the switching unit to the air extraction interface at the connection panel of the machine.
  3. Plug the switching unit into a power socket.
