2.1.5
Manual slide valve/Remote control
The manual slide valve (1) is used for adhering and releasing
the load and, in the case of an optional radio remote control, as
a backup in the event of a remote control failure.
Press in and move to the right is suction. Press in and move to
the left is release.
When using a radio remote control (2), the manual slide valve
must be set to open (On). Button 2 (On) on the remote control
serves for adhering the load. To release the load, buttons 1
(Off) and 3 (Off) must be operated simultaneously.
2.2
Lifting loads
Place the vacuum unit on the clean and dry product to be picked up, whilst avoiding tilting. Make sure the load is evenly
distributed. Make sure that all locking pins are fixed correctly and securely.
The negative pressure will gradually increase in the vacuum tank and the rest of the system. The suction cup is placed on
the element to be lifted. Set the manual slide valve to open, (B-
D) or press the “On” button of the transmitter (BER-DER).
The suction cup is now in connection with the vacuum tank. When the vacuum gauge indicates
–0.7 bar and the green
light has come on, the device is ready to lift. When the negative pressure drops below -0.7 (as indicated by the vacuum
gauge and/or red light), the lifted product must be put down immediately. The defect in the vacuum unit must be remedied
first before you can start working with the vacuum unit again. Alternatively, the element to be lifted may be too porous for
this vacuum unit. The speed at which the vacuum builds up depends on the size of the suction cups and the density of
the product to be lifted (false air factor).
2.3
Transporting a load
Avoid sudden movements of the load.
The user operating the remote control must always clearly and unambiguously inform the co-user of his intended actions.
Always keep an eye on the vacuum gauge. Never lift loads when the vacuum of -700 mbar has not yet been reached. If
the needle of the pressure gauge moves into the red danger zone, lower the load immediately.
Make sure the vacuum is not switched off when a load is being moved.
2.4
Putting down a load
Put down the load on a safe, clear and flat surface so that it cannot shift or topple over.
Only release the load when it stands securely on the ground. Do not grab hold underneath the load when it is being
lowered, because this may cause serious injuries. The manual load is released when the manual slide valve (1) is set to
Off, (B-D) or when the two Off buttons on the transmitter (2) are pressed simultaneously. (BER- DER) The connection
between the vacuum unit and the suction cups is interrupted now. Air is allowed underneath the suction cup at the same
time, causing the load to be released.
