3. INSTALLATION, OPERATION, FILLING PROCEDURE
3.1. INSTALLATION OF THE COMPRESSOR UNIT
The compressor frame is equipped with anti-vibration
mounts and thus a machine base or special means of secur
ing the compressor are not necessary.
The compressor unit is not seawater resis
tant. At operation in salty air spray com
pressor with anticorrosive protection (e. g.
Quicksilver Corrosion Guard). Electric
driven units should be operated and stored
below deck. Units with petrol engine should also be
stored below deck after the filling process.
Outdoor location
For installation observe the following:
- Locate the unit level.
- On units with petrol engine it is most important that only clean air
be used, position compressor in direction of wind so that exhaust
fumes are blown away from the unit. It is good practice to have
an intake hose of at least 3 m length with pre-filter and intake fil
ter. Pre-filter to be located 2 m above ground. See Abb. 11 and
chapter 4.5.1. This arrangement will ensure necessary spacing be
tween exhaust outlet and air inlet.
Abb. 11 Outdoor location
Wind
Exhaust gas
- The use of a windvane is recommended. Turn unit as soon
as wind direction changes.
- On petrol or diesel engine, operation unit must only be lo
cated outdoors, never indoors.
- Take care that no vehicles are in direct vicinity with en
gines running.
- Do not operate unit in the vicinity of open fire (flue gas!).
Indoor location
- Ensure adequate ventilation.
- Here too, air must be free from exhaust fumes and haz
ardous vapours (e.g. smoke, solvent vapours, etc.).
- If possible install unit in such a manner that the com
pressor fan can get fresh air from outside, for instance
through an opening in the wall. Distance from wall should
be at least 0.5 meters.
Never operate petrol driven units indoors
!
3.2. ELECTRICAL INSTALLATION
For installation of electrical equipment observe the follow
ing:
- In the annex of this instruction manual you will find the
standard schematic diagrams valid for the respective
compressor unit. To connect the compressor control sys
tem, use only the diagram contained in the control box of
the unit, because any deviations from the standard dia
grams according to order are marked there.
- Observe regulations of local electricity supply company.
- Connection must be carried out by an expert only. Units
which are operated with 380/400 V are delivered with an
electric plug. All other units are delivered without a plug
and have to be equipped with a suitable plug depending
on the country.
- Ensure correct installation of protective conductor.
- Check conformity of motor and control device tension
and frequency with those of electric network.
- Adjust motor protection, thermal overload relay. For start
over contactor adjust to motor amperage rating. For start
via star-delta contactor adjust to motor amperage rating
x 0.58.
For example: motor amperage rating = 10 Amp.:
adjust relay to 10 x 0.58 = 5.8 Amp.
- Fuse motor correctly (see table below; use slow-blow
fuses, only).
