GENERAL 3-3 System Diagram 3-3-1 CSOF-M3PL(H), CSOF-M5PL(H) [ Fig.3-7 ] System Diagram The CSOF-M Series are an oil-free scroll air compressor. In an operation, a main motor is run to initiate the compression at an airend. The external air is filtered through a suction filter before entering into the airend. The compressed air is stored into an air tank via a check valve (non-return valve). The temperature of the compressed air discharged from the airend is at least 392℉.
GENERAL 3-3-2 CSOF-S8PL(H), CSOF-S10PL(H) [ Fig.3-8 ] System Diagram The basic principle of the CSOF-S8PL(H) and CSOF-S10PL(H) is equal to that of CSOF-M3PL(H) and CSOF-M5PL(H). However, the CSOF-S8PL(H) and CSOF-S10PL(H) have two airends to sequentially be started up depending on the load to be used. As there is no air tank in the compressor, a drain valve is used on the discharge end to drain the condensate water generated during the compression.
INSTALLATION 4.0 Installation 4-1 Inspection When you receive the compressor please inspect it closely. Upon delivery, carefully check the compressor for damage during transportation. If goods are received in damaged condition, it is important that you notify the carrier and insist on a notation of loss or damage across the freight bill. [ Fig.4-1 ] Name plate 4-2 Handling 4-2-1 Handling by a forklift When handling by a forklift, make sure that forks completely extend through the width of the unit. (Fig.
INSTALLATION 4-3 Installation 4-3-1 Where to Install Coaire air compressor is designed for the indoor use. The ventilation facility and piping affect the performance and the service life of the compressor. Please follow the instructions in the user’s manual. [ Fig.4-4 ] Installation of the Air Compressor 4-3-2 Ventilation Poor ventilation in the compressor room may raise the temperature of the air discharged.

INSTALLATION 4-4 Requirements for the Piping 1) Use a larger diameter and install the pipe without an excessive bending to reduce the pressure drop. 2) Always place a branch pipe on the top of a main pipe to reduce the discharge of oil or water. 3) For the compressed air pipes, reduce the number of sections bending and connecting, and the number of valves installed to reduce the pressure loss. 4) The increased pressure loss requires a high discharge pressure of the air compressor.
INSTALLATION 7) It is recommended that the thickness of the cable shall allow more than the minimum requirement specified for a power condenser, and the length of the cable shall be within 1.5 m. No wiring is necessary if there is a power condenser with a sufficient capacity in the bus conductor. 8) Leave intact the factory specification of the overcurrent protection device. If the change is unavoidable, keep the set values within the range specified in the user’s manual.

Also check if the indicator lamps are normally on in the control panel.
FUNCTIONAL DESCRIPTIONS 6.0 Functional Descriptions 6-1 Airend An oil free scroll airend is the most important part in the compressor. In any case, the oil is not entered into the compression chamber. As the inside of the compression chamber is delicate, entering the dusts or foreign substances results in a serious damage to the compressor. The airend consists of precision parts, and needs a special jig for a repair and maintenance.
FUNCTIONAL DESCRIPTIONS 6-3 Fan Fan is key part to keep proper temperature of airend, please keep clean and periodically remove dust and foreign object not to dysfunction. [ Fig.6-3 ] FAN 6-4 Cooler A cooler element is an aluminum cooler that is designed to be used up to 217.5 psi. Dust may increase the temperature in the cooler pin, which needs to be cleaned with the compressed air or a detergent on a regular basis. When cleaning, cover the electric parts to keep the water out.
CONTROL 7.0 Control 7-1 Controller Coaire air compressor uses a controller based on a microprocessor for an optimal operation of the compressor. The controller is a system that precisely determines the time to adjust the capacity to save the energy, gives an alarm to prevent the accident before happens, and notifies the information necessary for repair and maintenance. The system ensures the best automatic operation optimized by the set conditions and the machine conditions.

MAINTENANCE 8.
MAINTENANCE 8-3 Maintenance 8-3-1 Regular Maintenance of the Airend 1) Check if there is any abnormal vibration or noise during a routine operation, and contact the nearest distributor, if necessary. 2) There are two types of the scroll airend: Low Pressure (115 psi) and High Pressure (140 psi). The maintenance period is different by type specified in the identification plate attached on an airend. The standard specification of Coaire airend is a low pressure type.
MAINTENANCE 8-3-3 Adjustment of the Belt Tension Adjust the belt tension in first 500 hrs after the purchase, and every 3,000 hrs (6 months) thereafter in the following procedures. 1) Use a tension-meter to measure the displacement of each belt. 2) Loose the anchor bolt on the motor base, and use the tension adjusting bolt to adjust the tension with reference to the [Table 8-1]. 3) Align the motor, and tighten the anchor bolt on the motor base.

Do not check and replace the belt until the compressor is stopped and the main power is turned off. 2) Only use the belt specified by Coaire for a replacement. Do not use old and new belts mixed, and replace the entire set of belts all at once.
MAINTENANCE 8-3-6 Check valve CAP Compressed air leakage may come from suction filter originated form check valve leakage. In severe case, airend SPRING Back-lash occurred. This case may cause severe damage to SEAT airend because of foreign objects from outside. To prevent VALVE BODY possible defect, check valve every 2,500hours 1) Screw CAP open . 2) Check spring tension and SEAT of Check valve 3) Replace valve when it has been damaged. [ Fig.
TROUBLESHOOTING 9.0 Troubleshooting 9-1 Overview The following flow diagrams show the procedures to repair the typical failures. If the alarm is on and the compressor is stopped, do not restart the operation until the cause is clearly addressed and eliminated.
