3. INSTALLATION AND PUTTING INTO SERVICE
3.1. Installation
CAUTION Observe safety instructions!
Always stay away from the danger zone of a load being lifted!
3.1.1. Compressor installation
Keyword Instructions

Installation site
Ground: even, horizontal, firm

Check load carrying capacity of floor.

Air: as cool, clean and free of frost as possible, as low humidity as
possible Temp.: +3°C (37°F) ‐ +40°C (104°F) *

Sufficient ventilation of compressor room

Air intake must be unobstructed

Place air intake opening in a position where loose objects cannot be
drawn in.

Ensure installation site has sufficient lighting (for reading of instruments,
carrying out maintenance, etc.)

Lifting work
Secure all loose and swinging parts, before lifting the compressor.

Use an appropriate lifting vehicle (weight according to data sheet)

Always stay away from the danger zone of a load being lifted

Pipelines, pressure lines
Before assembling pipelines, remove all flanges, plugs, caps and sacks
using a drying agent.

Ensure that the pressure system can expand from the compressor to the
aftercooler or air system due to heat. Make sure it does not come into
contact with flammable materials.

Exhaust Exhaust ducts must have a diameter at least equal to that of the cooler
surface and should be 3m in max. length with one bow of 90°; for longer
ducts, use an additional fan with a capacity 20% greater than the
compressor ventilator

When using multiple units, make sure no compressor can draw in the
heated exhaust of another compressor.
*in case the ambient temperature is higher, please consult your dealer or the manufacturer

3.2. Connections
3.2.1. Compressed air connection
The unit's piping has been installed ready for operative use.
You must follow the following advice when connecting the unit to the compressed air system:
Keyword Instructions
Pressure
Connection
Shut‐off valve
Condensate
The unit must only be connected by an electrician
Observe the following when connecting the unit to the mains
3.2.2. Electrical diagram
See annex
3.2.3. Electrical connections
The unit has been wired so as to be ready for immediate use. You only need to connect the unit to the mains.
Keyword Instructions
Voltage
Direction of rotation
Fuses
Connection
Attention: Do not use plug if it's possible

Use fittings and pipe lines suitable for the operating pressure.

Do not operate the unit at a final pressure greater than that specified on
the name plate

A check valve between the unit and the compressed air system is not
necessary as one has already been installed in the unit itself.

Connect unit to the compressed air system stress‐free, and free from
vibration (via a flexible hose for ex.)

We recommend you also install a shut‐off valve to enable you to carry out
maintenance work on the compressor without having to remove pressure
from the compressed air system.

An automatic condensate drain can be installed after the aftercooler to
remove condensation from the compressed air

Only connect the unit to the supply voltage specified on the name plate of
the motor.

Follow correct direction of rotation! Anticlockwise when viewed from the
front.

Checking the rotational direction see chap. 3.3/3.4. Not necessary for
frequency‐controlled compressors

A primary fuse and master switch with EMERGENCY‐STOP function must be
installed by the Operating Company. The switch must have a capacity at
least 1.1 times the rated output of the motor and must be uniquely
assigned to the unit.

Ensure that the electrical network is sufficiently fused (see data sheet)

Lay the supply cable safely so that
people cannot trip over it.

Lead the cable with the wires L1, L2, L3, N and PE through corresponding
screw fittings (we do not recommend to use plugs) into the connection
cabinet.

Connect the wires to the appropriate terminals L1, L2, L3, N and PE
