Operating the device
Place the stainless steel press basket onto the base frame. Subsequently, insert the filter cloth/press
bag (not shown) into the press basket; at the bottom ofthe basket, fold the bag outside in. At the top,
the bag is folded to the outside; this makes filling of the fruit pulp easier. Place a container
underneath the drain. The press can now be filled with the fruit pulp.
lt
is not necessary to fill the
bag completely; pressing is much easier to complete with less fruit pulp. Fold down the bag over the
fruit pulp, and place the lid on top. Place the washer over the spindle and install clamping nut and
connect the Hydro Press to the main power supply, using the quick disconnect. Subsequently, open
the water supply line.
The incoming water (max. 3 bar) applies pressure to the sl
urry
. Press the top of the breather valve
until the air has been completely removed from the diaphragm. The juice flows through the press
basket into the chute ofthe Hydro Press Once the water pressure has reached 3 bar, the reliefvalve
opens automatically and the water discharges below. The water pressure can be read off the
pressure gauge and regulated by using the water tap. To do this, the tap is closed when the normal
pressure is exceeded. Once the pressure has dropped, the tap can be slightly opened again. The
pressure gauge is a simple way of how to monitor the working condition of your Hydro Press. A
regulating valve (pressure reducing valve) is advantageous and is most probably already installed in
the line and preset to 3 bar. N ow, the water tap can be closed again. Please wait until the juice has
completely drained. Open the water drain in order to drain the rubber diaphragm. Press the breather
valve again in order to fi.11 the diaphragm with air. The draining water may be collected in a
container and recycled later for cleaning the fruit or watering the garden. Once the water has
stopped draining, the Hydro Press is depressurized and the clamping nut can be loosened. Remove
the washer and the Iid. After all juices have been extracted, the bag pulled out, and the pomace
removed.
Even more juice can be yielded if during the starting phase a little more time will
be
allowed for the
juice to drain. This will cause the flow path inside of the sl
urry
to remain open.
lt
can be easily
regulated by opening and closing the water tap. Grind your fruit with the perfect mill, gaining a
perfect fruit pulp (fine and not too coarse) - Please also refer to our fruit mill. A slurry that is too
fine may generate problems with the press and makes the drainage ofthe juice very difficult. At the
same time, a coarse grind may prevent an optimum juice yield. Grapes must be removed from their
stems and well crushed.
Cleaning, maintenance, storage
Please clean the press as soon as possible after each use in order to prevent the sweet juices or fruit
residue to dry inside the press. Simply use water and a brush/sponge or cloth to clean the press.
Never use a wire brush or other abrasive cleaning equipment. The press cloth can also be cleaned
thoroughly with water. The cloth may be laundered in the washing machine, using laundry
detergent and a low water temperature (max. 30
°
C).
In order to ensure a long service life of the diaphragm, the press should
be
stored, if possible, in a
dark room sheltered from the environment and protected from sunlight. Continuous exposure to
sunlight (UV/ozone) causes synthetic rubber products to age faster and become brittle.
