We want to assure you that the installation height does not have any impact on the performance of the machine. However, it does affect the comfort level for the buyer during usage. With that in mind, we sincerely recommend installing the machine at a height that is suitable for comfortable usage. A height aligned with the user's height or at eye level is considered ideal for a pleasant and convenient experience. We genuinely care about your satisfaction and want to ensure that you can use the machine comfortably.
