3. Foundation:
• The compressor must be installed on anti-vibration mounts, acquired by the client. The set must be leveled
and the mounts must be adequate for the equipment's weight and vibration.
• The compressor models with vertical tank must be fixed on the machine room floor to avoid tipping.
• Compressors on wheels: In order to prevent damage to the compressor, it must only operate on a level
base or as recommended with a maximum of 15° (Figure 6.9). If the compressor is operating on an inclined
plane (maximum of 15°) the wheels must be chocked to prevent unwanted rolling.
4. Positioning:
• Keep a minimum clearance of 0.8m (32") from any wall or obstacle and minimum height of 2m (787") to
guarantee good ventilation during operation and for ease of eventual maintenance.
• Properly mark and delineate an area around the compressor to alert and prevent collisions with the equip-
ment (Figure 6.10).

5. Pneumatic connection:

• When connected to the compressed air network, the discharge connection must be fixed by means of a fle-
xible hose or expandable gaskets so that forces (loads), thermal expansion, tubing weight, mechanical and
thermal shock or obstruction will not be transmitted to the air tank. Non-observance of these orientations
may cause physical damage to the compressed air tank.
• For tank mounted product versions, the hose for the connection with the air network must support a minimum
temperature of 60º C. For the versions AD, the temperature must be 150º C.
6. Compressed air quality:
In applications where the required air must be free of solid particles and/or oil, (for example: medical, hospital,
dental, food applications, among others) oil free air compressor models must be used, connected to special air
filters after the compressor or next to the application area. Consult the manufacturer or SCHULZ AUTHORIZED
DEALER for more information.

7. Electrical connection:

• Consult a specialized technician to evaluate the general conditions of the electrical network and select the
adequate supply and protection devices.
• Existing legislation and standards in safety and low-voltage electrical installation must be followed, accor-
ding to the installation's location and country.
• Supply cable must be dimensioned according to the motor power, network voltage and distance to the elec-
trical source. See orientations in Table 6.2.
• Before connecting the equipment to the electrical supply, check if the compressor's voltage matches the
local voltage.
• In the Direct starter version (Three-Phase) it is necessary to install before the compressor, in the distribution
panel, phase failure and phase sequence relay and 3-pole circuit breaker/fuses, as shown in Table 6.2.
