GENERAL 3-3 System Diagram 3-3-1CSOF-S3PL(H), CSOF-S5PL(H) [ Fig. 3-3 ] System Diagram The CSOF-S 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℉.
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.

OPERATION 5.0 Operation 5-1 Commissioning ( Initial Operation ) 5-1-1 Structure of the Controller [ Fig. 5-1] Control Button 5-1-2 Checklists before the Commissioning 1) Check if the voltage of the main power is within a normal range specified. 2) Cut the main power to connect the power line to the control panel. 3) Check the connection of pipes, a power supply and a grounding. 4) Fully open a stop valve on the discharge pipe of the compressed air.
OPERATION 5-2 Routine Operation 5-2-1 Checklists before the Operation Check the following conditions before starting the operation. 1) Connect the main power 2) Push the “On/Off” switch into “On” and check the compressor is well started up, and the indicator lamp are normally on.
OPERATION 5-2-4 Stop 1) Push the “On/Off” switch into “Off”. 2) Turn the main power off. 3) Check if the internal pressure is completely discharged from the compressor. 5-2-5 Operation Log Regularly record the information about the operation events in the operation log to early find the failure of the compressor and to prevent the accident before happens. The information includes the discharge pressure, operating time, maintenance items and the time to replace the parts.
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 Cooler & Fan The cooler assembly consists of an air cooler, a cooling fan, a fan motor and a fan shroud (duct). 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. [ Fig.6-3 ] Fan [ Fig.

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 tensiometer 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.
MAINTENANCE 8-3-5 Cleaning the Suction Filter 1) Check the contamination level every 500 hrs. 2) Replace the heavily contaminated filter even before the replacement period. 3) Blow the element with the compressed air outward, and then by the side. 4) Keep dust and foreign substances out of the compressor during the assembly. [ Fig.8-6 ] Suction filter cleaning Caution A suction filter significantly affects the service life of an airend. Make sure to use only the genuine Coaire suction filter.
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. Always turn the main power off, and remove the pressure from the compressor prior to a repair and maintenance.
