Note the installation requirements: When replacing the coupling components, follow the equipment specifications to ensure that the coaxiality and other installation parameters meet the standards, and avoid secondary damage.

Replacement and Maintenance Precautions If the components show signs of aging and cracking of the hose, leakage at the joints, damage to the reinforcement layer, or bulging, they must be replaced immediately to prevent leakage of high-pressure media, which could cause safety hazards or affect system operation; When replacing, it is essential to use the original Fx1050Xf type components to ensure that their dimensions, pressure resistance level, and joint sealing are consistent with the original components. Non-original components may cause installation difficulties or premature damage due to poor compatibility; During installation, pay attention to the bending radius of the hose (it must not be less than the specified value, usually 6-8 times the diameter of the hose), avoid excessive twisting or stretching, and keep away from high-temperature components and rotating parts. If necessary, use pipe clamps for fixation to reduce vibration and wear.

Replacement and Maintenance Suggestions If you find that the hose has bulges, cracks, aging and hardening, joint leakage or exposed reinforcement layer, it must be replaced immediately to avoid explosion under high pressure and potential safety accidents; When replacing, use the original AC hose to ensure that the pressure resistance level, joint sealing performance and system match. Non-original hoses may have insufficient pressure resistance or poor interface sealing due to poor material quality; During installation, avoid excessive bending or twisting of the hose (the bending radius should be greater than 5 times the diameter of the hose), keep away from high-temperature components (such as exhaust pipes) and sharp objects, and use special pipe clamps for fixation to prevent vibration wear.

Replacement and Maintenance Precautions If you find that the return oil pipe has corrosion perforations, damaged interface threads, deformed pipes, or leaks, it must be replaced immediately; otherwise, it will cause oil loss, insufficient lubrication, and lead to wear of the main engine. When replacing, it is necessary to use the original factory metal return oil pipe to ensure that the size, interface are consistent with the original components, and avoid installation difficulties or leakage due to mismatch issues. During installation, check whether the sealing parts (gaskets, O-rings) are in good condition. If necessary, replace them simultaneously; when tightening the interface, operate according to the specified torque to prevent excessive tightness from causing thread damage or insufficient tightness that leads to leakage.

Faults and Maintenance Suggestions Common Problems and Solutions: Poor or blocked drainage: This is often caused by accumulated impurities. You can disassemble the valve body to clean the filter screen. In severe cases, the original valve needs to be replaced. Valve always closed or always open: This may be due to a fault in the electromagnetic valve coil or damage to the controller. You need to check the circuit and replace the corresponding components. Leakage: Caused by aging seals. It is recommended to directly replace the entire drainage valve (the original kit includes all seals). During maintenance, it is necessary to regularly (every 3 months) check if the wiring is loose, clean the drainage outlet, ensure that the winter environmental temperature is not lower than 0℃, and prevent freezing and cracking.

Replacement and Maintenance Recommendations: Replacement Cycle: Generally, replace the filter every 1,000 - 2,000 hours or 6 months (whichever comes first). In environments with high dust concentration (such as mines, cement plants), this period should be shortened to 500 - 800 hours. Replacement Indicators: If the intake resistance becomes excessively high (over 100 - 150 mbar, which can be observed through a pressure gauge), if the compressor's exhaust volume decreases, or if there is abnormal noise from the main unit, it is necessary to immediately check and replace it. Maintenance Tips: During daily maintenance, the filter element can be removed. Use compressed air to blow off the surface dust from the inside out (pressure ≤ 5 bar), but do not wash it with water; during replacement, clean the interior of the filter housing to ensure there are no residual impurities.
