Plumbing Installation Instructions

LISTED 995C

WARNING: Elderly persons, pregnant women, or those suffering from heart disease, high blood pressure, diabetes, or who are otherwise not in good health, do not use this device unless

directed to do so by a physician. Also, do not use steambath while under the influence of alcohol.

IMPORTANT: the warranty of this product is voided if it is used in a commercial application or for anything other than a residential steambath installation.

The Steamist “SM” Generator comes factory assembled, carefully wired and tested.

The Plumbing Installation must conform to local and national codes. All electrical power should be turned OFF when working with Steam Generator.

1. Pre-Installation

Be sure that the proper size Steam Generator has been selected by using the sizing page in the “Full

Line Brochure,” “Pricing Guide,” “The Generator Sizing Guide,” Architectural Guidelines,” or in the

Residential Systems/Steambath Product Information section of the Steamist web site www.steamist.com.

CAUTION: An improperly sized Steam Generator may NOT produce the amount of steam necessary to reach selected temperature.

IMPORTANT: Refer to page 4 for model required for cubic foot rating.

The Steam Generator should be located as close as possible to the Steam Room/Shower or tub enclosure. Steam pipe should NOT exceed twenty-five feet in length. If the steam pipe exceeds ten feet, use an appropriate pipe insulation rated for a minimum of 212°F. Possible locations include Vanity, Closets, Attic (insulated), or Basement near bath area. The serial number plate should be visible and the Steam Generator should be accessible for service. Refer to Installation Suggestion on the page

4. Do NOT install Generator outdoors, in a moist humid area, or in an area where parts may freeze or corrode. Also, do NOT install near flammable

materials such as paints, thinners, gasoline, etc. The steam line and safety valve reach a temperature of 212°F during operation and should be appropriately protected to prevent personal injury by accidental contact.

2. Plumbing Rough-In

Plumbing rough-in is required for the water supply and steam line, this should be completed before the walls are closed. For operation, the “SM” Steam Generator

requires a ⅜” O.D. copper tubing to the fitting on the

generator for water inlet and ¾” copper or brass pipe for steam outlet.

NOTE: Safety Valve should be connected to a minimum ¾” indirect waste or as required by local plumbing codes. In the unlikely event this valve should open, the discharge must be directed to prevent damage to the home.

Water Inlet - A water line should be roughed-in from

existing ½” hot or cold water pipe. Using a ½” x ⅜”

tee, cut and solder tee into the existing water line.

(See Figure 3 on page 3). Solder a piece of ⅜”

copper tubing into tee. Rough-in for water supply is now complete.

Steam Outlet - Rough-in the steam line using a minimum of a ¾” copper or brass pipe, do NOT use black iron or galvanized pipe, it will rust and discolor the wall of the steam bath. The steamhead location should be 18” above the shower floor or 6” above the rim of the bathtub, as far from the seating area as possible.

CAUTION: No shut-off valve can be installed in the steam line. Do NOT create traps or valleys in this line which would trap condensation and block the flow of steam. The steam pipe should be pitched toward the Steam Generator allowing condensation to run back toward the Steam Generator (preferred), or toward the steamhead.

3. Steam Generator Installation

The Steam Generator should be mounted in a location convenient for hook-up and service by the Plumber and Electrician.

CAUTION: The steam generator is designed to be used ONLY in an upright and level position, to do otherwise would damage the unit and void the warranty.

The steam generator can be mounted to a wall or set on the floor. However, the unit must be secured. To secure the unit to a vertical wall, loosen the two screws holding the electrical access cover, remove cover (see Figure 1). Located inside the cabinet near the top left and right corners are mounting holes. Place top cover back and secure.

Connect the 3/8” water supply, described in Section 2 to the Steam Generator by first soldering a 3/8” valve into the previously installed water line. The valve must be kept in an open position during normal operation. In areas where high water pressure may be a problem a water hammer arrestor or a pressure regulator should be installed. Complete water supply by connecting 3/8” copper tubing from the valve to the water inlet compression fitting. Refer to Plumbing Diagram below.

IMPORTANT: Do NOT use a “saddle valve” or piercing type valve for water connection.

Connect the steam line from rough-in location described in Section 2 to the ¾” nipple on the steam generator using a union.

In the shower, place the center of the escutcheon onto the steam pipe and screw the steamhead into place. Care must be taken not to scratch the steamhead or escutcheon with wrench. Be sure the steam slot in the steamhead is facing down. After the plumbing connections are complete the electrician may finish wiring the unit.

WARNING: When installing a steam pipe into a steam room made out of Acrylic, Cultured Marble, Corian, Swanstone, Resin, Plastic or an equivalent type of material, consult the manufacturer of the material for their recommendation on location of the steam pipe. Verify that the type of material used for the construction of the steam room is rated for a steam room environment. When installing a steam pipe, in the mentioned material type rooms, it is very critical in making sure that when the steam pipe protrudes into the steam room that it is centered in its 1¼” hole and does not touch the edge of the wall material around the steam pipe.

IMPORTANT: An optional steam diffuser (Not Included) is strongly recommended for small steam rooms. This option helps to better diffuse the steam and makes the steambath more comfortable. This option may not be necessary in larger steam rooms where the bather is sitting a few feet away from the steamhead.

IMPORTANT: Install

steam head 18” above

the shower floor or 6”

above the rim of the

Bathtub.

Master/Slave Installation Instructions

Introduction:

The System-30 consists of one SM-15 Master and one SM-15 Slave. The Master/Slave generators are 15 kilowatts each. This instruction sheet is to be used in conjunction with the standard SM-15 Electrical and Plumbing instructions (Pub. No. 323 and 324). All connections both plumbing and electrical must be kept completely separate.

Danger: To reduce the risk of explosion. DO NOT interconnect the steam outlets.

Operation: The Master/Slave generators operate as two completely separate generators. The steam bath controls are connected to the Master Generator. When the Master Generator is started up from the controller, it then turns on the Slave Generator and both units produce steam at the same time.

NOTE: The following specifications apply to each of the two Generators, wired and plumbed separately.

InstaMist

Info

Warning: Do not turn on the power to the steam generator until the installation is

complete and the unit is ready to test/use. If the steam generator will not be in use for long periods of time (over 6 months) the power to the steam generator should be turned off.

Important: In order for the InstaMist feature to function, water must always be in the tank. For this reason the Optional Auto-Drain can NOT be used with any InstaMist generators.

The Steamist InstaMist Feature (-IM) is only available as a factory installed option on the following Models: SM-5, SM-7, SM-8, SM-11, SM-12, SM-15, System-18, System-24, and System-30.

Live Power

Connecon

The Steamist InstaMist generators feature pre-heat function, which provides a generous volume of steam in under a minute. This new feature maintains an average water temperature of 180°F in the stainless steel reservior. When the steam generator is activated, the pre-heated water inside the steam generator quickly reaches the boiling point, allowing steam to flow out in under a minute.

All Steamist steam generators with or without InstaMist are factory assembled and tested. There are no additional Plumbing or Electrical requirements needed in the field for generators with the InstaMist feature. The installation instructions for the plumber and the electrician are provided with the steam generator and need to be followed.
