This document is an installation, operation, and maintenance manual for Mr. Steam residential steambath generator systems, covering models MS90E – MS400E and MSSUPER1E – 6E.
Function Description:
The Mr. Steam steambath generator systems are designed to produce steam for residential steambath enclosures. These units heat water to create steam, which is then delivered to a steam head within the steambath room, providing a relaxing and therapeutic steam bathing experience. The systems are controlled by various Mr. Steam controls (iSteam®, AirTempo®, iTempo/Plus®, iTempo®, Home Wizard®, and iGenie®), which allow users to set temperature and duration. Optional features like AutoFlush® and AromaSteam® enhance the user experience and system maintenance.

- Water Quality: Recommended feedwater quality includes hardness (1-5 gpg), P. Alkalinity (85-410 ppm), T. Alkalinity (200-500 ppm), and pH (8.0-11.4). An AutoFlush® system is recommended for generator longevity in hard water areas.
Usage Features:
- Controls: Compatible with Mr. Steam iSteam®, AirTempo®, iTempo/Plus®, iTempo®, Home Wizard®, and iGenie® controls for setting temperature and duration.
