The device is used to press the inlet and outlet tubes into the evaporator. The operator places the evaporator in the prepared base and then puts the appropriate tubes into the two sliding holders. Subsequently, the tubes are manually pushed to the evaporator. After this step, the operator starts the machine cycle using the two-hand control. During this cycle, the evaporator is clamped, the tubes are pressed and the OK stamp is stamped. After the end of the cycle, the press tools are pulled apart and the upper clamps are released, then the operator can remove the finished evaporator.
