• The machines are equipped with an ampere
meter, which can be used to monitor the whole
drying operation . Any value below 4 amperes
indicates an optimum air flow when the com-
pressor is in operation . Areas which are es-
pecially moist generate a higher flow resis-
tance . The DA 3 is able to focus on exactly the-
se areas and can therefore significantly reduce
drying times . Please note that because the en-
tire compressor performance is focused on
only one drill hole, it can make sense to ope-
rate the compressor in the 4-5 ampere range .
This allows high concentrations of moisture to
be drawn off both quickly and effectively . The
ideal number of suction and post-arc current
openings can only be checked when the DA3
has opened all the channels (off) .Values over 5
amperes indicate that the compressor is not
running economically . The compressor should
not be operated at this setting over a longer
period .
• The VE4-S must be protected by a power sup-
ply with 16 A 1~ 230V/N/PE .
• The electrical supply is protected accordingly
during operation with the VE 4 and VE 6 .
• We recommend using a starting current limiter
from the Trotec programme if problems with
blown fuses arise in old buildings during opera-
tion with the VE 4 or VE 6 .
• The VE4-S is equipped with a service socket
(max . stress 6,3 A; 1~ 230 V N / PE) . The socket
is protected by a safety fuse on the control panel .
• The air is suctioned in and discharged through
a side channel compressor turbine .
Starting up
• When using a four point distributor (fig .4), please
make sure that the yellow connecting stoppers,
which are screwed into the distributor, are
screwed on tight . Please screw on tightly if
this is not the case . Only unscrew the necessary
number of stoppers required for the dying process
prior to starting up the unit .
• WARNING: When using a four point distributor,
at least 1 air inlet must be opened during ope-
ration due to the power of the unit .
• The turbines in the VE-series are special high
performance designs, which have been opti-
mized for restorative drying. You should there-
fore NEVER switch on the turbines if the con-
nection stoppers are completely closed; the
immense force could warp the drive shaft,
thus resulting in a financial write-off . Each
motor is tested in the plant before delivery and
delivered ready-to-use .
• Operating range/Limit range:
Operating range: The ampere meter indicates
values around 4 amperes .
Limit range: If values of more than 5 amperes
are indicated, the installation has to be chan-
ged . No operation of the compressor .

• Connect the compressor to the appropriate power
supply . The unit is immediately ready for ope-
ration .
• Press the ON/OFF switch .
Shutting down
• Press the ON/OFF switch .
• Wait until the motor has stopped and the turbine
is no longer rotating .
• Screw the stoppers which were removed be-
fore the unit was started up back into place
and tighten accordingly .
• The motor must reach a complete standstill
before it is switched on again, as this may
otherwise result in a write-off .
Cleaning and maintenance
• Always remove the main plug from the main
supply before carrying out cleaning and main-
tenance work .
• Remove the lid from the housing and clean
with compressed air – not with water . If the
housing of the unit has been cleaned with
water, then the housing must be completely
dry before the unit is installed .
• Please check all cables and plugs regularly for
any signs of wear and tear or damage . Dama-
ged cables or plugs must be replaced immedi-
ately .

• The turbines are special designs with specified
performance curves and only suitable for the
transportation of clean air and clean gases . If
the transportation medium contains solid par-
ticles or other forms of contamination, then a
filter must be installed on the suction side (e .g .
water separator, micro filter) .
• The bearings in the turbine are completely en-
cased, maintenance-free, special high tempe-
rature bearings . The grease packing lasts a whole
product life-time .
• Maintenance and repair should only be carried
out by the firm TROTEC .
