The CP Compressors should never be operated beyond its capabilities or in any way which does not comply with the instructions contained in this operating and maintenance guide. Chicago Pneumatic Compressors will decline any responsibility if these instructions are not respected. This equipment has been factory tested and satisfies normal operating conditions: they must not be exceeded as this would place the machine under abnormal stress and effort.

Section 1 - Description A - General Information The Chicago Pneumatic Compressors CP model air compressor is a compressed air unit and is presented as an entire unit completely assembled and tested. It is driven by an electric motor and enclosed in a sound proof cowling which is necessary for proper cooling. The compression element is a single-stage, oil-refrigerated, rotary screw compressor. The oil is stored in a vertical tank, which is fitted with an oil separator.

Water outlet Manual condensation water draining Water inlet Automatic condensation water draining Unplug and decompress the compressor before maintenance 6. Hot parts DANGER This symbol identifies immediate hazards which will result in severe personal injury, death or substantial property damage.
Section 2 - Installation Prevailing wind A - Handling The CPVS Compressor must always be handled with care. It may be lifted either with a forklift truck or by means of a travelling crane. In the latter case, precautions must be taken so as not to damage the unit's cowling. L Flexible fitting V B - Room The CPVS is designed to operate in a frost-free environment, supplied with air at a temperature of no more than 104 °F.
F - Electric cabling Each CPVS is wired for a pre-determined voltage, i.e. 460 V. NEVER OPERATE THE CPVS ON A VOLTAGE OTHER THAN THAT SHOWN ON THE ELECTRIC CABINET. The electric current supply to the CPVS must comply with the following table : Type of cable to be used : Power cable size (for a maximum 32.8 ft length) VOLTAGE CPVS Model 460 V 40 AWG4 50 AWG3 60 AGW1 75 AWG0 SAFETY REGULATIONS It should be remembered that safety regulations require : • An earth socket to be used.
Section 3 - Implementation A - Preparation for start-up Before starting the set for the first time, the operator must get to know the different systems. The main locations which have to be examined are shown on the figures. IMPORTANT Before start up, make sure that transport red wedges have been effectively removed. ATTENTION The power circuit must be turned whenever adjusting electrical equipment or to prevent accidental starting.
Section 4 - Operation Key fig. 4 A - Air and oil circuits 20 Compressor 21 Suction element The air is sucked into the compressor through a filter (rep. 23). This air passes through the compression element where it is mixed with oil injected during compression. Inside the oil tank, the compressed air is pre-deoiled by shocks, then flows through the oil separator (rep 49).
Section 5 - Options A - Level detection bleed valve (Fig. 6) 2 - Option overview - This option is used as a replacement for the standard filter 1 - Description The BEKOMAT type level detection bleed valve allows all air consumption to be avoided while the compressor is not running. 2 - Option overview - There is no air consumption due to the level detection system : an inductive sensor detects the level of condensation and thus controls the opening of the electric bleed valve.
3 - Technical features Operating temperature : -104 °F to + 194 °F C - Pre-filtration panels Fig. 8 • Binding of the air / oil separator before 6000 Hours thus an increase in maintenance cycles and maintenance costs. Access to the filtering medium is allowed by removal that does not require any particular tool. The panel frame can be unlocked manually in order to clean the medium. Exceptional longevity of the medium that is quick to take apart.
D -Automatic restarting 1 - Description This management system enables the compressor to be restarted automatically after a power outage. 2 - Option overview Not available in standard version in order to prevent any incident during maintenance operations carried out by an untrained person. This option is proposed in cases where the production of compressed air should suffer only the minimum periods of shutdowns. The standard microcut time accepted by AIRLOGIC is approximately : 250 ms.
G - Centrifugal separator (See B Section 3) Fig. 13 1 - Description This device allows bleeding of the condensates formed in the air cooler. 2 - Description of the option The cooling of the compressed air allows the suction air to be dried, thus removing the humidity that collects in the bottom of the separator after being condensed in the aftercooler. The condensates are evacuated from the separator through a trap with a solenoid drip valve or a trap with level detector if this option is installed.
Section 6 - Specific information for CPVS 40-50-60-75 Refer also to the chapters concerning the standard machine. "CPVS" compressors are compliant with the Electromagnetic compatibility in industrial environments Standards 50081-2 and 50082-2 A - Description (cf Section 1) Standard equipment A electronic frequency adjusting device replaces the star-delta starter. A fuse holder section switch completes CP standard's safety devices.
D - Commissioning 1 - Preparation for start-up (See Section 3). ATTENTION The power circuit will have to be cut off when adjusting the electrical equipment or if inadvertent start-up is to be avoided. Before start-up, check the following points: 1 - Ensure that the unit has a suitable earth, 2 - Check the oil level in the compressor, NOTE: the tank was filled in the factory with a suitable oil. See Section 8 - A for the quality of oil to be used and for the oil renewal conditions.

Under normal operating conditions, the CPVS compressor must provide full satisfaction.
Section 7 - Maintenance The summary on the CP instrument panel shows at a glance the type and periodicity of operations to be carried out for the compressor to function correctly. The maintenance period is limited to several essential operations. It is strongly recommended that the power supply be cut off during any adjustment or repair.
A - Oil level and change (see fig. 19) (see B Section 1) The recommended oil used for the first compressor fill up is a mineral oil with the following properties : - viscosity: 40 cSt at 104 °F viscosity index: 90 minimum antioxidant additives anti-rust additives anti-foam additives THE FIRST OIL CHANGE MUST BE CARRIED OUT AFTER THE FIRST 500 HOURS OPERATION.
D - Oil and air cooler Fig. 20 - Oil return pipe The aluminium oil and air cooler is a vital part in the CPVS system. Please take care of this element. To prevent the nest of tubes from being deformed or damaged, when assembling or disassembling the radiator unions and hoses, the radiator sleeves' must be kept rotating by means of a wrench. The outer surface of the nest of tubes must always be kept clean in order to enable proper heat transfer.
Section 8 - Operating incidents The staff in charge of maintenance of the CP Compressor must become fully acquainted with this machine, in order to be able to easily diagnose any anomaly. Under normal operating conditions, the CP compressor must provide full satisfaction. A - Main incidents The main incidents likely to occur are listed below, along with the remedies to be applied. The markers of the indicator lights relate to the control panel. Observed defects Possible causes 1.
