Vaillant rubber feet for aroTHERM split – set of 4, replacement mounting feet (MPN 0020252091)
Set of 4 Vaillant rubber feet designed as replacement mounting feet for aroTHERM split heat pump units. These grommet-style feet provide vibration damping and stable support for outdoor or indoor installation where compatible with the aroTHERM split range. Intended for service, repair or component replacement to restore correct mounting and reduce noise transmission, the set replaces worn or damaged mounting feet to maintain operational stability of the heat pump.
The rubber feet are made to absorb vibration and reduce structure-borne noise, helping to protect the heat pump and its mounting surface. As direct replacement parts, they match the original mounting geometry and material properties for a reliable fit. The set of four allows full replacement of the unit's feet in a single service operation, and the resilient rubber material resists weathering and compression under normal operating conditions.
Shut down and isolate the heat pump according to the manufacturer's safety instructions before beginning work. Remove the existing mounting feet by loosening any retaining hardware and extracting the old grommets. Fit the new rubber feet into the original mounting points, ensuring correct orientation and full seating. Reinstall any fasteners to the specified torque and verify that the unit sits level and stable on all four feet. After installation, reconnect power and perform a functional check to confirm reduced vibration and correct operation.
Inspect the replacement feet periodically, especially after extended operation or exposure to severe weather. Replace the set if signs of cracking, excessive compression, or other deterioration appear. Use only compatible mounting feet designed for the aroTHERM split series to ensure proper fit and performance.
