Page 5: Introduction
Pneumatic presses series M INTRODUCTION We thank you for your trust, which you demonstrated by purchasing our pneumatic press. In order for it to be used successfully and for a long period we ask you to follow the instructions and warnings for a safe and proper use. The instructions are intended for the operator and they should always be kept at hand. -
Page 6: General Safety Precautions
General safety precautions Due to its moving parts and to the pressure in the drum, the pneumatic press may be a threat to its environment. Therefore, strictly observe safety precautions when operating the press. Unqualified and unauthorized person is not allowed to use the press. -
Page 7: Safety Devices
Pneumatic presses series M Safety devices The press is equipped with safety devices which ensure safe work and undisturbed operation of the press. 4.3.1 Emergency STOP button When you push the emergency STOP button the press immediately stops its operation. Never use the emergency STOP to interrupt the grapepress normal running. -
Page 8: Overload Relays
Presses with axial filling can also be equipped with a sound alarm. The alarm is triggered if the pressure is exceeded or the press is overfilled. Make sure not to exceed the max. pressure allowed douring the filling of the press. -
Page 9: Mounting And Storage Of The Press
Pneumatic presses series M The PS_10,_12 and _16 size presses have hoisting openings in the hatch brackets. Attach the hoisting strap or lined steel rope hooks in the openings. To unload and transport the press, apply appropriate lifting equipment (forklift, lift) and hoisting straps or lined steel ropes. -
Page 10: Switching On The Press
SWITCHING ON THE PRESS Electrical connection The electrical connection of the press must be carried out by skilled personnel (electrician)! Electrical connections (including earth lead and protection) should be performed in accordance with applicable standards. Electrical diagrams are attached to the manual! Connect the press to the required source of electrical power (single phase, three phase). -

Page 13: Pneumatic Press Operation
Pneumatic presses series M Pneumatic press operation Pneumatic press is a technical-oenological process tool designed for controlled pressing of grapes. It allows the wine- maker to actively intervene in the processes in the course of pressing, to continually adjust and govern the processes. Soft pressing of grapes or lees by means of a membrane and compressed air prevents mechanical damaging of grapes (less damage to the hard parts of grapes) and in turn minimises the leaching of undesired ingredients. -

Page 15: Materials
Pneumatic presses series M An electric motor with reduction gear drives the drum via a chain transmission. Prior to each filling of the drum / rotation of the drum, suction fix the membrane to the drum walls by means of the vacuum pump. -
Page 16: Press Drum
Press drum The press drum is constructed according to pressure vessel guidelines (PED 97/23/EC). The horizontal shape of the drum, combining large length and small diameter, allows faster outflow of juice, which results in less sediment in the must. On the inside, the drum is lined with an impermeable membrane shaped to cover half of the drum surface. -
Page 17: Control Box
Pneumatic presses series M Control box The automatics (controller) provide for proper flow of the pressing process in accordance with the set parameters. The press can be fitted with AE automatics (factory preset programmes) or AV automatics (factory preset programmes that can be set and adjusted during the pressing process). -
Page 18: Optional Equipment
Optional equipment 8.8.1 Strainer on the collection pan outlet Install the strainer on the drain opening from the inside. The strainer traps pips and other particles from the must; thereby, only pure liquid passes from the collection pan into the container. - Page 19 Pneumatic presses series M The dimensions of the hatch depend on the press type. 1 – mounting bracket 2 – fixing screw 3 – door handle 4 – door cover To perform maceration, follow these instructions: Before filling the press, rotate the drum to bring the hatch to its top position. Insert drain channel plugs.

Upon the first switching of the cooling medium the surplus air from the in-between room between the cooling jacket and the drum should be released. The venting is performed by unwinding the screw on the venting connector.

Page 25: 10 Cleaning Of The Pneumatic Presses
Pneumatic presses series M 10 CLEANING OF THE PNEUMATIC PRESSES Before performing any maintenance, disconnect the press from electricity. Be careful not to wet the electric equipment (control panel, electric cabinet, electric motor) with the water jet. Protect the control panel with an impermeable foil (polyvinyl) when washing the press. When the press is cleaned by chemical substances (only cleaning substances for pneumatic presses can be used), the worker is directly exposed to possible dangerous effects of these substances, used for cleaning. -

Page 27: Reassembly Of The Draining Channels
Pneumatic presses series M Step 4: Remove the draining channel plugs on the drum exterior. Step 5: Following this procedure, remove all drain channels and remove them from the drum. Clean the channels with water. Clean the drum interior as well. During washing, the drum should be orientated so that the water can drain out of the cleaning opening, or in case the press does not have such an opening, out of the drain channel. -
Page 28: Cleaning Of The External Parts Of The Press
When washing, move the hose in and out for maximum effect. Use the same procedure to clean all channels. Optional: Integrated high-pressure cleaner with hose and nozzle (optional on PST) The high-pressure cleaner is built into the press. The cleaning procedure is the same as described above. -
