STEAM ROOM GUIDELINES
1. Steam room must be completely enclosed, with full walls, door, floor and ceiling.
2. It is recommended that a gasketed door is used for steam containment.
3. To prevent slip and fall hazards, non-slip flooring or non-slip floor strips must be installed in the steam room.
4. Check the suitability of any materials with Delta Faucet Company. Walls and ceilings must be constructed of water-resistant, non-corrosive surfaces,
such as tile, marble, or other non-porous material. Avoid the use of plastic which may not be rated for the 212°F temperature of the steam exiting
the steam head.
5. The ceiling should be sloped to "minimize" dripping of condensation. The recommended slope is 2" per foot.
6. Provide a floor drain.
7. No heating, venting or air conditioning devices should be installed inside the steam room.
8. Windows that are part of the steam room should be double paned and tempered safety glass.
9. For optimum performance, limit steam room ceiling height to 8 feet. Exceeding 8 feet may require a higher-rated steam generator.
NOTE: Max. ceiling height is 10 feet.
Pre-Installation
1. Be sure that the proper size Steam Generator has been selected by using the sizing page in the Full Line Brochure, Pricing Guide, The Genera-
tor Sizing Guide, The Configurator Tool Guide, or in the Residential Systems/Steam bath Product Information section of the Delta website - www.
deltafaucet.com.
2. For optimum performance, the Steam Generator should be located as close as possible to the Steam room, Shower or tub enclosure using a ¾"
copper pipe (1/2" copper pipe is also acceptable, but not preferred due to the potential for increased system noise). If the steam pipe exceeds ten
feet, it should be insulated using appropriate pipe insulation rated for a minimum of 212º F. Maximum steam pipe distance should be kept under
25 feet but not exceed a total of fifty linear feet. Refer to Installation Suggestions.
Plumbing Rough-in
1. Plumbing is required for the water supply and steam line. This should be completed before the walls are closed. For operation, the 5P-EST04,
5P-EST06, 5P-EST07 & 5P-EST10 Steam Generator requires a ⅜" O.D. copper tubing to the fitting on the Generator for water inlet and a ¾"
copper or brass pipe for steam outlet.
NOTE: Pressure safety valve should be connected to a minimum 3/4" indirect waste or as required by local plumbing codes. In the event this valve
should open, the discharge must be directed to prevent damage to the home.
2. Water Inlet - Rough in a water line, 120 PSI max, to the hot or cold supply. A shut off valve with a 3/8" connection to the steam generator is to be
provided at the generator location (see Figure 3).
3. Steam Outlet - Rough in the steam line using a 3/4" copper or brass pipe; do NOT use black iron or galvanized pipe; it will rust and discolor the
wall of the steam bath. Do NOT use any plastic type pipe or fittings. The steam head location should be 12" to 18" above the shower floor or 6"
above the rim of the bathtub, and should be as far from the seating area as possible.
No shutoff 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 allowing condensation to run back
toward the Steam Generator (preferred), or toward the steam head. When installing multiple steam generators DO
NOT interconnect the steam pipes. The steam line and safety valve reach a temperature of 212°F during opera-
tion and should be appropriately protected to prevent personal injury by accidental contact.
Steam Generator Installation
The Steam Generator should be mounted in a location convenient for hook-up and service by the plumber and electrician.
1. 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, loos-
en the two screws holding the electrical access cover. Remove cover. Located inside the cabinet near the top left and right corners are mounting
holes. Place top cover back and secure.
2. Connect the 3/8" water inlet to a shut off valve as described in Plumbing rough-in step 2 (above). The valve must be kept in an open position
during normal operation. In an area where water hammer is a problem install a water hammer arrestor in the line. Refer to Figure 2.
IMPORTANT: Do NOT use a "saddle valve" or piercing type valve for water connection.
3. Connect the steam line from rough-in location described in Section 2 to the 3/4" nipple on the Steam Generator using a union (not supplied).
An improperly sized Steam Generator may NOT produce the amount of
steam necessary to reach selected temperature.
Do NOT install near flammable material such as paints, thinners, gaso-
line, etc.
Steam generators must NOT be installed outdoors, in moist, humid
areas, in areas prone to freezing, or in extreme heat such as an unventi-
lated attic. To do so will void the warranty.
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.
