HOW THE STEAM GENERATOR FUNCTIONS The steam generator uses an immersion-type, capacity water heater to raise the water to the boiling point, producing steam vapor. The steam escapes from the heating vessel through a pipe which connects to the steam head in the steam bath enclosure. Multiple controls are designed into the system to provide protection and shutdown in the event of equipment malfunction or ihip!opei operation. Controls are included for monitoring internal temperature and water level; a safety valve provides protection in the event of steam blockage. The water level in the vessel is maintained by an automatic low-water sensor and water fill solenoid. A solid-state circuit board monitors the system and cycles the unit in response to remote steam bath temperature controllers and timers. INSTALLATION

•

MS (residential) series steam bath generators should be properly sized for the volume of the serviced steam bath area. To determine the proper unit model for your needs, find the cubic volume of the area to be serviced by multiplying the interior length

x width x height (in feet). Check the Specifications to be sure that your system will meet these requirements. For proper operation, the shower or tub enclosure should be sealed on all sides, top and bottom, and have a fully-closing door. For both existing and new installations, ensure that enclosure walls and ceiling are covered with a water-resistant, non-corrosive surface such as tile, formica, fiberglass or deck paint. Before installing the unit, carefully read the following preliminary installation information and requirements data to be sure that your system can be installed safely and easily, providing you with long-term use and enjoyment. LOCATING THE STEAM GENERATOR UNIT Select a location as near as possible to the steam bath enclosure, but no further away than 25 feet. Typical locations, shown in figure 6, include: (a) a linen closet, (b) vanity cabinet, (c) attic, or (d) basement. Install the unit to allow access to the front panel door, drain valve, plumbing and electrical connections for maintenance purposes. Standard brass or copper fittings are recommended for all water and steam line connections. The use of unions to make all plumbing line connections is highly recommended.

Figure 6. Typical Locations

Caution Do not install the steam generator unit in an unheated attic or basement where the temperature may fall below freezing. The steam generator unit can be placed directly on the floor, shelf-mounted from wall studs, or hung from ceiling joists. Refer to Figure 7 for complete installation dimensions and details concerning location of plumbing and electrical connections.

Note For maximum operating efficiency, install the unit on a solid, properly-leveled surface.

USING TUB/SHOWER AS A STEAM BATH If you are planning to use an existing shower or tub/shower as a steam bath, be certain that it is completely sealed on all sides, top and bottom. The door should be fully-gasketed to prevent steam leakage. Walls and ceiling should be completely covered with a water-resistant, non-corrosive surface.

CONSTRUCTING A SEPARATE STEAM ROOM If you are planning to build a separate steam room, the following requirements should be considered: 1. Steam area must be completely enclosed, with full walls, doors, floor and ceiling. Size of enclosure and choice of steam generator must be compatible. 2. Use a full-gasketed door for best sealing. 3. If tile-type flooring is used, install anti-skid strips or treads for safety.

7. Slope ceiling slightly away from the bench area to prevent condensate from dripping on the bench. 8. Avoid use of exposed or untreated materials which are subject to rot. PREPARING PLUMBING CONNECTIONS All plumbing must be performed in strict accordance with local codes, by qualified personnel. Obtain the water supply from the nearest water line. Making the connection to the hot water line, rather than the cold will provide operating economy as it takes less energy to raise hot water to the steam point. Observe the following requirements: 1. MS steam generators require a 3/8-inch water line connection (3/8-inch NPT). Larger-diameter piping will require a suitable adapter. Use unions for pipe connections to simplify post-installation maintenance. 2. Make sure that the water inlet line is clear of foreign materials by flushing the line thoroughly before completing the connection to the unit. 3. Always install a strainer with an easily - removable filter screen (no. 100 mesh) in the inlet V:‘,-.1 4. Do not install a valve in the steam outlet line the unit! The steam line connections are 1/2 - inch NPT: use brass or copper piping for steam line connections and insulate steam lines for safety and reduction of heat losses. 5. For installations in a shower stall or new room, locate the steam head between 6 to 12 inches from floor level, with the slotted end facing downward. For tub/shower enclosures, install the steam head within 6 inches above the tub ledge. When used on shower stall with acrylic or other non-heat resistant floors, install shower head approximately 20-30 inches from the floor. 6. Pitch steam piping to avoid valleys, which tend to collect condensate.

4. Walls and ceiling, must be tiled or otherwise waterproofed.

7. Where local codes permit, provide a connection to the drain outlet (1/2-inch NPT). Pitch drain line downward since draining is aided by gravity.

5. Provide a floor drain and hose for washing-down. 6. Provide a bench seat, sloped slightly to allow for run-off of steam condensate and wash-water.

8. Where permitted by local codes, plumb the safety valve to the drain line, making sure that no valve can impede flow from the safety valve.

plumbing and electrical hookups and clearance to operate DRAIN valve.

PREPARING ELECTRICAL CONNECTIONS All electrical wiring must be done strictly in accordance with National and Local Codes and be installed by qualified personnel. Observe the follow-

2. Connect 3/8" NPT water line to WATER INLET fitting. Use of brass piping and unions is recommended. Install a shutoff valve between the unit and the water feed line.

ing requirements: 1. Minimum supply wiring sizes are 10 AWG for models MS-65 (4.5 kw), MS-90 (5 kw) and MS-150 (6 kw); 8 AWG for MS-225 (7.5 kw) and MS-300 (8.5 kw); 6 AWG for MS-400 (9.7 kw). 2. Supply wiring should be suitable for operation at temperatures of 194 degrees F., (90 degrees C.) minimum, and be rated and sized in accordance with the kw, voltage and phase of the steam bath and electrical codes. 3. The steam generator unit must be connected to electrical ground via the ground terminal in the case, beneath the power contactor. 4. Install a separate circuit breaker ON-OFF switch between the main AC supply and the steam generator unit. Use a 30-ampere circuit breaker for all models except the MS-225, MS-300 and the MS400, which require a 50-ampere breaker.

•

3. Drill a 1-1/8" hole into the steam bath enclosure for connection to the steam head. Locate the steam head as instructed in "Preparing Plumbing Connections". Connect 1/2" NPT steam line between STEAM OUTLET fitting and steam bath. A slight slope to the steam line will help avoid condensate accumulations. Insulate exposed steam piping for safety and reduction of heat losses. 4. Install steam head (1/2" NPT fitting) onto the steam line termination so that slotted steam outlet faces downward. Do not install a shutoff valve on the steam line!

5. Connect 1/2" NPT drain valve to DRAIN fitting, where allowed by local codes. This drain is used for periodic cleanout to remove accumulated contaminants. As an alternative, the drain line can be plumbed directly into the steam line, only if the elevation of the steam bath generator is higher than the steam outlet, for another alternative, omit the drain line completely and empty the contents of the unit into a receptical of some type.

INSTALLING THE STEAM GENERATOR 1. Install the unit directly on a level floor or sturdy,

level raised platform or shelf, minimum dimensions 18" wide by 14" deep, with adequate support. For proper steam generation, the unit must be leveled, in an upright position. Provide adequate room about the front, rear and right sides to allow for maintenance access, connection of

6. Plumb safety valve to drain line, where permitted by local codes.

SCHEMATIC

MAINTENANCE Mr. Steam steam generators are designed for unattended operation and require little maintenance. Other than periodic draining, maintenance procedures are not required. Every 2 months, or more often in "hard" water conditions, the drain valve should be opened for approximately 10 seconds, flushing out accumulated materials, salts and other particulates which are natural byproducts of boiling water. Note: for best results, this should be done immediately after using the steam generator, while contents are still hot and with the timer off! The unit will refill automatically when power is reapplied. In areas of hard water, a water softener is recommended in order to prevent calcium build up which is not covered under Sussman's limited warranty for parts.

Refer to the schematic diagrams, Figures 9 and 10, and the disassembly view, Figure 11, and the accompanying parts list. Use the schematic diagram as part of a troubleshooting aid for checking electrical circuits and wiring interconnections. Refer to the disassembled view for identification, removal/replacement of components. Index numbers assigned to this view are keyed to the associated parts list, which may be used for ordering parts. When ordering, identify the part by its name and part number, as well as the unit model number.

TROUBLESHOOTING AND REPAIRS

The steam generator unit is designed with built-in fail-safe features so that it will shut down automatically in the event of excessive temperature or insufficient water supply. Before troubleshooting the unit itself, check outside the steam generator to see if other problems are causing the trouble, then refer to the troubleshooting chart.
