Yuanyin Cola Machine – Filter Cartridge Replacement Step-by-Step Tutorial
I. Filter Cartridge Removal Steps (In Chronological Order)
Hold the filter housing body, rotate the lower structure to separate it, and remove the old filter cartridge.
Disconnect the water inlet hose: press the clasp and keep it in the retracted/spring-back state, then pull out the hose. Do not pull forcefully.
Fit the dedicated filter wrench onto the filter housing connection, turn the filter housing assembly counterclockwise to loosen it, and complete the removal.
II. New Filter Cartridge Installation and Reset Procedure (In Chronological Order)
Pre-rinse the new filter cartridge with clean water, then install it into the filter housing.
Align the positioning holes of the filter housing and the filter cartridge for installation (may be installed upside down). Ensure the seal is properly seated. Do not force assembly without proper alignment.
First tighten the filter cartridge manually, then use the dedicated wrench to perform the final clockwise locking. The wrench is mandatory and cannot be omitted.
Insert the water inlet hose fully to the bottom and confirm it is securely clasped. Restore the system in the order of “water → electricity → air”. Perform the water and air supply tests to ensure the equipment operates normally.
III. Key Operational Requirements
Operation Step Key Requirement Note
Hose Disconnection Press the clasp and keep it retracted, then pull out the hose Manual operation, no special tool required
Filter Housing Removal Turn counterclockwise Must use the dedicated filter wrench
Filter Cartridge Installation Align the positioning holes; ensure seal is properly seated Do not force assembly without proper alignment
Final Locking Hand-tighten initially + final clockwise tightening with wrench Wrench is mandatory and cannot be omitted
System Reset Insert water inlet hose fully; restore in specified order Water → Electricity → Air; order must not be reversed
IV. Core Conclusion
Filter cartridge replacement for the Yuanyin cola machine is a standardized mechanical operation requiring no electronic adjustments. The entire procedure relies on physical structure coordination and the use of dedicated tools. Proper alignment of the positioning holes and final tightening with the wrench are the core rigid requirements for ensuring sealing reliability. Both are indispensable; failure to follow either may result in equipment water leakage or abnormal air supply.
