*ES 1/7 Bp Pack

**Optionally available

The ES 1/7 Bp is a mobile, battery-operated spray unit for surface disinfection.

To optimize the adhesion of the disinfectant solution to sloping, vertical or hard-to-reach surfaces, the disinfectant solution can be electrostatically charged by switching on a high-voltage cascade.

1. Remove the suction pipe from the tank.

   ---

   

2. Push the suction pipe into the socket on the device as far as it will go.

1. Charge the battery pack (see operating instructions and safety instructions for the battery pack and the charger).

1. CAUTION

   Risk of injury and damage if the battery pack is not engaged!

   A battery pack that is not properly engaged can fall out and cause injury or damage.

   Make sure that the battery pack engages correctly in the battery mount.

   Push the battery pack into the battery mount on the device until the battery pack audibly latches into place.

1. DANGER

   Danger of eye damage, skin and mucous membrane irritation, breathing difficulties and symptoms of poisoning when handling disinfectants!

   Contact with disinfectants can cause serious eye damage, skin and mucous membrane irritation and breathing difficulties. The ingestion of disinfectants can lead to symptoms of poisoning such as nausea, headache and vomiting.

   Avoid contact with eyes, skin and mucous membranes. When working, wear suitable safety goggles or a face mask as well as electrostatically dissipative protective gloves and safety shoes in accordance with EN ISO 20344. The insulation resistance must not exceed 100 MΩ.

   Wear a suitable respirator of class FFP2 or higher. Do not breathe the spray mist and aerosols and ensure good ventilation.

   Do not drink disinfectant or disinfectant solution.

   Observe the safety and handling instructions on the product labels or in the disinfectant's safety data sheets.

   Fill the disinfectant into the round bottle up to the MAX mark shown.

   ---

   

2. Screw the dosing head onto the round bottle.

1. Turn the tank approx. 45° clockwise and remove it.

   (Not required when putting into service for the first time).

   ---

   

2. DANGER

   Danger to life and risk of serious illness through the use of unsuitable disinfectants or incorrect concentration, dosage or contact time!

   If unsuitable disinfectants are used for the application, or if disinfectants are applied in too low a concentration or amount, or if the specified contact times are not adhered to, then their effectiveness can be reduced or completely lost.

   Use only suitable disinfectants, and follow all the manufacturer's instructions for use, mixing ratio, dosage and contact time.

   Squeeze the round bottle in the middle until the required amount of disinfectant has flowed into the dosing head.

   ---

   

   Take the following into account:

   1. The specifications of the detergent manufacturer for the mixing ratio of disinfectant and fresh water

   2. the corresponding scale on the dosing head

   3. the capacity of the tank

3. Open the cover on the dosing head.

4. Fill the disinfectant into the tank.

   ---

   

5. Close the cover on the dosing head.

6. Fill the tank with clean fresh water (max. 40°C) until a disinfectant solution is mixed in the required concentration.

   Fill the fresh water at most up to the MAX mark shown.

   ---

   

7. Place the tank on the device and turn it approx. 45° counterclockwise.

   ---

   

1. ATTENTION

   Risk of damage from dry running!

   When operating the device with or without an empty tank, there is a risk of damage from the pump running dry.

   Only operate the device as long as the tank is attached to the device, and there is disinfectant solution or fresh water in the tank.

   Vent the device before using it for the first time and if necessary.

   ---

   

2. Hold the device so that the nozzle is pointing upwards at an angle of approx. 45° and not at yourself or a third party.

3. Press the ON / OFF button.

   The device switches on.

   Operate the device until the disinfectant solution emerges from the nozzle in the form of an uninterrupted, finely atomized spray cone.

   The device is now ready for use.

   ---

   

• The disinfectant solution should be applied by a steady pendulum movement of the device, at a speed similar to the application of spray paint.

  Work from top to bottom on vertical and sloping surfaces.

• Switch on the electrostatic charge of the disinfectant solution in order to optimize the film formation and adhesion to sloping, vertical or difficult to reach surfaces. To do this, press the ON / OFF switch for electrostatic charging on the top of the unit to the "Blitz" position. Press to position "0" to switch off.

  ---

  

  Note

  Be sure to touch the ground contact on the ON / OFF button.

  Do not wear insulating, but rather electrostatically dissipative gloves and shoes in accordance with EN ISO 20344 with an insulation resistance of max. 100 MΩ, otherwise the device will not be earthed, and the electrostatic charge will not function.

  To achieve an optimal electrostatic effect, the potential equalisation can optionally be carried out by means of a functional earthing, see chapter Earth the unit (optional).

• If the capacity of the battery pack is almost exhausted, the device switches off.

  Note

  In order to avoid a damaging exhaustive discharge of the battery pack, the device switches itself off before the battery pack is completely discharged.

  Take the battery pack out of the unit and charge it, see chapter Ending operation.

• In the event of work interruptions, before transport and after the end of work, press the locking button.

  The ON / OFF button is locked, and the unit is protected against unintentional switching on.

  ---

  

To optimise the electrostatic effect, the unit can be earthed. To do this, use the optionally available sets, see chapters Description of the device and Spare parts list.

1. Plug the earthing plug into an earthed socket.

   ---

   

2. Connect the earthing cable to the earthing plug.

3. Connect the earthing cable to the earthing connection.

   Note

   To extend the operating radius of the unit if necessary, connect another earthing cable using the adapter as shown.

1. Loop the shoulder strap around so that the pad rests on the shoulder.

   ---

   

2. Attach the snap hook of the shoulder strap into the eye at the top of the device.

3. If necessary, adjust the length of the shoulder strap.

   ---

   

   1. Shorten the shoulder strap: Hold the length adjuster firmly and pull on the end of the strap.

   2. Lengthen the shoulder strap: Hold the length adjuster firmly and pull the strap opposite the end of the strap.

1. Fill the tank, see chapter Filling the tank.

6. Move the device in even pendulum movements over the area to be treated, and apply the disinfectant solution as a closed film.

   Note

   If the electrostatic charge is switched on, it can lead to unpleasantly noticeable electrostatic discharge through the operator. If you find this uncomfortable, switch off the electrostatic charge using the ON / OFF switch for electrostatic charge.

7. Release the ON / OFF button.

   The device switches off.
