The ANEST IWATA OIL-FREE SCROLL COMPRESSOR, available in models SLE-2/2H, SLE-3/3H, and SLE-5/5H, is designed to provide oil-free compressed air for various applications. This instruction manual serves as a comprehensive guide for safe, efficient, and long-lasting operation of the compressor.

Function Description

The ANEST IWATA OIL-FREE SCROLL COMPRESSOR is an air compressor that generates compressed air without the use of oil in the compression chamber. This design ensures that the output air is free from oil contamination, making it suitable for applications where air purity is critical. The compressor operates by using scroll technology, which involves two interleaved spiral-shaped scrolls—one fixed and one orbiting—to compress air. This method is known for its quiet operation, smooth performance, and energy efficiency.

The compressor is designed to deliver consistent air pressure, with specific maximum and minimum control pressures depending on the model (e.g., 116 psi for SLE-2, SLE-3, SLE-5 models, and 145 psi for SLE-2H, SLE-3H, SLE-5H models). It is equipped with a control system that manages the compression process, ensuring that the unit operates within specified pressure ranges. The system includes a pressure switch that monitors and regulates the discharge pressure.

For electrical safety and proper operation, the compressor requires a specific electrical source (e.g., 1Phase, 208-230V, 60HZ with VFD soft starter; 3Phase, 208-230V, 60Hz with VFD soft starter; 3Phase, 460V, 60Hz with Magnetic starter). It also features protection mechanisms, such as an overcurrent protector (thermal protector for magnetic starter, VFD Equipped for VFD soft starter), to prevent damage from electrical faults.

The compressor is designed for indoor installation in a safe, clean, and well-ventilated area, free from flammable gases, organic solvents, corrosive gases, excessive dirt, and dust. Proper grounding is essential to prevent electric shock. The unit is intended solely for compressing air and must not be used with respiratory equipment or for life support applications.

Usage Features

The compressor is designed for straightforward operation, with clear instructions provided for installation and test run procedures. Before initial use, users are advised to inspect the product for any shipping damage and verify that all accessories, including the instruction manuals, base covers, rubber mats, and ball valve, are present.

Installation involves securing the unit on a level floor to minimize vibration and noise. Adequate space around the compressor is required for safe inspection and maintenance. Proper ventilation is crucial, especially when operating in enclosed spaces, to dissipate heat and prevent overheating. The manual provides guidelines for British Thermal Unit (BTU) output for different models to assist in selecting appropriate ventilation.

Piping connections should be made with a rubber hose and flexible tube to prevent vibration transfer to the main piping, which could affect the compressor's print board. It is also recommended to install drain valves at low points in the piping system to remove condensate.

Electrical wiring must be performed by a qualified electrician, adhering to specified cable sizes and breaker requirements to prevent electric shock, fire, or serious injury. The main electric source must always be turned off before any inspection or wiring work. The unit must be securely grounded.

During the test operation, users are guided to check for proper air receiver piping connection and open the compressor air outlet ball valve. The compressor's start-up and pressure increase should be monitored. If reverse rotation or abnormal sounds are detected, the unit must be stopped immediately, the main electric source turned off, and two of the three phases changed to correct the rotation. The maximum and minimum control pressures are to be verified by operating the unit with the ball valve closed and then gradually reducing pressure.

The compressor is designed to operate within an ambient temperature range of 36°F to 104°F. Operating outside this range can lead to unit failure, freezing, or a shorter lifespan.

Maintenance Features

Regular maintenance and inspection are critical for ensuring the safe, efficient, and long operating lifetime of the ANEST IWATA OIL-FREE SCROLL COMPRESSOR. The manual provides a detailed maintenance schedule based on operational hours or years, whichever comes first. These intervals are based on an ambient temperature of 86°F, with recommendations to shorten maintenance periods in warmer or more severe operating conditions.

Key maintenance tasks include:

• Drain: Daily draining of the air receiver is required.
• Abnormal Sound/Vibration: Daily inspection for any abnormal sounds or vibrations.
• Ventilation Fan: Smooth rotation of the ventilation fan should be checked regularly.
• Intake Filter: The intake filter should be blown clean with an air gun and replaced if dirty.
• Intake Metal Wire: The intake metal wire needs to be cleaned periodically.
• Safety Valve: The safety valve should be checked by lifting its stem at maximum pressure to ensure air blows out.
• Belt: The belt should be inspected, readjusted, or replaced as needed. Belt tension is crucial; if the V-belt makes a slipping sound at startup, it indicates a need for readjustment or replacement. An exclusive tool is required to measure belt tension, and a distributor should be contacted for this service.
• Intake Hose/Nylon Pipe: These components should be inspected and replaced if cracks or hardening are observed.
• Magnet Switch: Inspect and replace as necessary.
• Motor Insulation: Check the motor insulation periodically.
• Motor: Inspect and replace the motor if abnormal.
• Pulley: Check the pulley groove for wear.
• Temperature Sensor: Measure the resistance of the temperature sensor and replace if abnormal.
• Pressure Sensor: Check the operation of the pressure sensor and replace if abnormal.
• After Cooler: Clean the outside of the after cooler.
• O-rings and Check Valve: These parts should be replaced according to the schedule.
• Air End Seal Parts/Re-grease: Inspect and re-grease the air end seal parts using genuine Iwata grease.
• Air End Fan FS-OS Fins: Clean these components.
• Air End: Replace the air end as per the maintenance schedule.

The manual emphasizes the use of genuine parts for maintenance to prevent equipment failure and ensure optimal performance. Air intake filters are not covered under warranty, and users are advised to keep extra filters on hand. For items marked with an asterisk (*) or those requiring specialized knowledge, users are instructed to contact the shop where the compressor was purchased or a qualified electrician.

The document also includes a troubleshooting guide to help users identify and remedy common problems, such as the compressor not starting, caution/condition displays, lack of exhaust pressure increase, safety valve activation, and abnormal sounds. This guide provides potential causes and corresponding remedies, with a clear distinction between tasks users can perform and those requiring professional assistance.
