Table of Contents in these instructions. If spare parts are received without this certificate, there is a risk that these are not genuine Sauer spare parts. In such an istance please contact our Customer Service.
Emergency service (international): +49 172 4 14 63 94 E-Mail: service@sauersohn.de Web: www.sauersohn.de Note! If you have questions regarding your Sauer Compressor, please state Compressor model and serial number (see chapter 11 “Spare Parts and Accessories” or nameplate on the compres- sor).
1.6 Specific instructions Lists General lists are hyphenated. e. g.: Compressor cooling consists of – fan wheel, – fan wheel cage, and – cooler assembly. Instructions Individual instructions or multiple instructions requiring action but where the sequence is of no importance are normally denoted by a bullet-point.
Safety Safety 2.1 Conditions of use This Sauer Compressor must be used for the compression of air. The Sauer Compressor must not be used at ambient temperatu- res below +5 °C. Any other use not as specified, requires the ex- plicit consent in writing from J.P.
2.3 Safety information - Warning & Caution The safety information in these instructions is presented as ’high’ risk and ’lower’ risk, as follows: Warning - Danger! High risk. Ignoring this safety information can cause personal injury, or death, and significant equipment damage. Caution - Note! Less risk.
Safety labeling affixed to the machine must not be altered or re- moved. Replace damaged or lost safety labels immediately with an approved replacement. Sauer compressor models with an EC Manufacturer's Declarati- on or EC Declaration of Conformity are marked with the following safety labels:...
The fusible plug can only be used once. If it blows, it needs to be replaced with a new one. As an alternative to the fusible plug, the Sauer compressor can be fitted with a temperature sensor to protect against a compres- sor cooling failure.
(see Chapter 4). The Sauer compressor can be arranged with a sound-dampening enclosure to reduce the noise. This sound-dampening enclosure is available as optional accessory from J.P. SAUER & SOHN. Danger! When the compressor is operated without sound-dampening en- closure, hearing protection should be worn when working near to the compressor.
2.8 Personal safety Only personnel authorised by J.P. SAUER & SOHN are permitted to Service the Sauer Compressor! Before commencing work they must have read and understood the instructions in the Manual, and must be familiar with all safety devices and safety regulati- ons.
Safety 2.9 Personal protection The user should provide personal protection (e.g. hearing protec- tion, safety boots, etc.) for the operator, or Service engineer car- rying out any work on the Sauer compressor.

The condensate is drained through a drain line. As a drain valve, a solenoid valve is installed in the drain line. The drain valve is draining/ open as long as the Sauer compressor is switched off. The drain pressure relief valve should close some seconds after starting, to allow the Sau- er compressor to run-up against pressure.
3.4 Compressor Control System - Indicators and Control Note! If the Compressor Control system is supplied by J.P. SAUER & SOHN read the documentation supplied. On the front of the Compressor Control, the following indicators and control features can be found:...

• Immediately on receipt of the Sauer Compressor it should be checked for completeness and any damage. • The transport company and J.P. SAUER & SOHN must be no- tified immediately of any damage to the packing or the ma- chine.
Transport and Installation 5.2 Storage before Installation If the Sauer Compressor has to be stored before installation, do not unpack, and store in the following conditions: – temperature: +5 to +40°C; – relative humidity 30 … 95%, non-condensing; – dry area, under a roof and protected against the weather;...
Note! If in doubt regarding the suitability of the intended place of instal- lation, please contact J.P. SAUER & SOHN. Sauer can provide help with the design of a ventilation, system if required. For proper installation observe the installation instructions and the following.

5.5 Stop/Start pressure switch setting(s) Note! Any final pressure switch should be connected directly to the compressed gas storage vessel to ensure a proper compressor operation. Keep in mind the pressure drop between the compressor and the compressed gas storage for setting the maximum pressure. The safety valve of the final stage will blow if the set value of pressure is too high.
Transport and Installation 5.6 Filling with oil Note! Unless otherwise ordered, Sauer compressors are delivered without oil. Oil filler Dipstick Danger The compressor's crankcase oil sump must be filled with oil be- fore initial operation! Use recommended lubricating oil (see Chapter 10: “Lubricant Table”).

Operation 6.1 Safe operation Danger! Only authorised persons are permitted put into operation and operate the Sauer Compressor! Danger! Turn on and start the compressor only if – it has been checked for proper working condition; – all tools and foreign objects are removed from the machine.
6.2 Operation modes When the power supply to the Sauer compressor is turned on, it can be started with one of the following two operational modes: – Normal operation mode “Manual“: The compressor starts and keeps running until it is stopped or turned off with either the operation mode selector or the main switch.
7. If necessary, correct any faults. See also Chapter 7 “Trouble- shooting“. 8. Complete the start up journal and send it to J.P. SAUER & SOHN service department. The start up journal is in the Ap- pendix of this Manual.

Storage, Preservation – “lay-up” procedure Storage, Preservation – “lay-up” procedure 9.1 Safety when storing and removing Danger! The compressor shall only be removed and “laid up” by trained specialists of the owner. These specialists must be familiar with the protection devices and regulations before starting the work. Any work on the electrical installation must be carried out by qualified electricians only.
If idle, every 4 weeks perform a test run for at least 30 minutes. Additional corrosion prevention measures are not required. When the Sauer compressor is to be layed-up for more than 12 weeks, preservation with a flushing or preservation oil is recom- mended.
