4. Installation - Operation
General Specifications
High pressure compressors are complete units for filling cylinders with compressed air at 225 bar (3200 psi) and
330 bar (4700 psi). They are mostly used for compressing breathing air for divers, fire brigades, military, paint ball
applications, etc.
Mistral is a 3 staged, piston, air cooled compressor with 3 cylinders, 2 intercoolers and 1 final aftercooler,
condensate separator after the second stage aftercooler, accompanied with automatic and manual drain, pressure
control in all stages of compression, with pressostat and mechanical safety valve as well as one filtering stage at the
final pressure (after the third stage):
The Final Filter (dehumidification) contains Molecular Sieve and air purification with Activated Carbon.
Installation - First start of the compressor
All compressors are tested and pre-adjusted by the manufacturer before they are shipped to the buyer.
They can start their operation immediately on the following conditions that are considered necessary, for safety
and ease.
Anyone who will be handling the unit must read carefully all contents of this manual so as to have full knowledge of
the product.
1. Choose carefully the installation place of the compressor. The place must not be burdened by unfavorable
environmental conditions (toxic substances – explosives – fumes – dirt – debris etc.
2. Place the compressor in a well-ventilated area. Make sure that the intake air for the compressor is clean
and cool. Prevent the hot cooling air from recirculating to the cooling air intake. Make sure that foreign
objects cannot get into the compressor with the intake air. Make sure that the intake air does not contain
any smells, fuel or fumes, explosive or inflammable gases or harmful substances.
3. Turn the compressor using the fly-pulley and make sure it turns freely. Do the same after overhaul of the
unit or a long-term out of service period.
4. Check the rotation direction (follow the arrow) by pressing instantly the start-stop button. The same check
should be carried out after any service or reconnection of electrical supply.
5. Before any start of the compressor, check oil level. It should be between the minimum and maximum limit.
6. The compressor should be placed in a completely horizontal position. If during operation there are
vibrations, adjust the anti-vibration pads of the stand until vibrations are minimized.
7. Start the compressor by pressing the start button on the electrical box.
8. When Main Switch is installed: After turning on the main switch, user must first press the reset button
and then the start button in order to start the compressor.
9. Stop the compressor by pressing the stop button on the electrical box when the pressure reaches the
maximum or when the final stage safety valve opens. In auto-stop version the compressor stops
automatically at the pre-adjusted final pressure.
10. After stopping the compressor open the manual drains (one under the separator and one under the final
filter) so as to remove condensate.
11. During every start of the compressor (in versions without auto drains), open only the drain valve of the
nd
2
stage. Then during the regular operation of the compressor open both 2
every 15 minutes.
ATTENTION:
Larger oil quantity may increase pressures inside the block, cause leaks of larger oil quantity in the pneumatic air
resulting in the creation of chars in the valves, burden the filters and affect their life duration, as well as the quality
of breathing air.
Smaller amount of oil means inadequate lubrication affecting the life duration of the compressor.
