Before Installing

Read these instructions before installation or service. Although each MS steambath generator has been fully qualified for shipment by MrSteam, the following must be reviewed for proper, safe and enjoyable steam bathing.

Verify that the model and accessories are correct, including incoming line voltage.

Ensure steambath generator has been correctly sized for the steambath room. Pay particular attention to room volume and construction. If any questions, please refer to MrSteam Size and Selection.

Marble or glass walls or ceilings, or exterior walls enlarge the room’s size, requiring a generator larger than one based only on the room’s cubic foot (L x H x W) volume.

The physical size of the unit, clearance for plumbing servicing and its distance from the steam room must all be considered before final installation.

Warning!

MrSteam steam generators are connected to 240V line voltage and contain live electrical components. All installation and service to be performed by qualified electricians and plumbers only. Installation or service by unqualified persons may void the warranty.

Recommendations for Steamroom Construction

  1. The steam room must be completely enclosed with full doors, walls, floor and ceiling. All crack and joints must be filled with a silicone sealer.
  2. The steam room must be watertight: walls, ceilings and floors must be made of waterproofed materials such as tile, cement, marble, etc. Ceramic tile is the most commonly used material for steam rooms. It should be well grouted and properly sealed. Avoid the use of untreated and exposed materials which are susceptible to decay or corrosion.
  3. Insulation should be utilized within the walls, ceilings, etc.
  4. Normal ceiling height is 7 feet 6 inches: the ceiling should be sloped 2 inches per foot in order to prevent condensation from dripping on the occupants. The ceiling can be sloped from the center to minimize height reduction.
  5. The steam room should have at least one bench for bather's comfort. It should be sloped slightly to provide for condensate runoff.
  6. The steam room should contain at least one drain for condensate runoff and cleaning.
  7. Flooring should be skid-resistant for safety.
  8. Vents inside the steam room are not recommended, but if used, they must be positive closing vents. The vents must form a vapor-tight seal. Ducts must be waterproof.
  9. If a skylight or window is used, it must be double-pane, and skylights must be closed off and sealed at the ceiling height.
  10. The shower door used must be water tight.

Locating the Steam Generator Unit

Select a location as near as possible to the steam room. Typical locations include: closet, vanity cabinet, insulated attic, or basement.

  1. Locate the steambath generator as close as practical to the steam/shower room and within 50 feet of the steam room.
  2. Do not install the steambath generator inside the steam room.
  3. Do not install the steambath generator outdoors.
  4. Do not install the steambath generator in an unheated attic or basement where water could freeze.
  5. Do not install the steambath generator near combustible or corrosive materials and chemicals.
  6. Install the steambath generator on a solid and level surface.
  7. Install the steambath generator in an upright position.
  8. Install an antiwater-hammer device if required.
  9. Provide access to both ends of steambath generator for servicing.
  10. Steam line, safety valve, and drain valve become hot during operation. Provide appropriate protection.
  11. MrSteam controls can be located inside the steam room or on the outside of the steam room. See the Control Installation and Operation Instructions for specific details. If the Smart/Two or Smart/Plus controls are located outside the steamroom, a remote sensor (part number MSNC) is required.

Note: The Smart/One, Smart/Remote, Smart/Two and Smart/Plus controls are UL Approved for installation and operation in a wet location.

Installation

Plumbing

All plumbing shall be performed by a qualified plumber and in accordance with applicable national and local codes.

  • Use unions on all pipe connections.
  • Use only brass piping or copper tubing.
  • Do not use black, galvanized or PVC pipe.
Water Supply (3/8" NPT)
  1. Connect to hot or cold water line. Hot water line is preferable. Hot water should not exceed 160 degrees F. Softened water is also preferable.
  2. Provide a shutoff valve in supply line.
  3. Do not overheat inlet solenoid valve with solder connections. Overheating will damage parts.
  4. Flush inlet water line thoroughly before making connection to unit.
  5. Strainer is required if there are solid particles in the water.
  6. For best performance, water pressure should be 15 to 20 psig.
  7. Provide antiwater-hammer device if required.
Steam Outlet (1/2" NPT)
  1. Do not install a valve in steam line. The flow of steam must be unobstructed.
  2. Use 1/2-inch brass or copper pipe from unit to steam head.
  3. Insulate steam line using pipe insulation rated 250 degrees F or higher.
  4. Pitch steam line to avoid valleys and trapping of condensate.
  5. Pitch steam line ¼" per foot towards steam head or steam generator.

Steam Head
  1. Locate steam head 6 to 12 inches from floor, except:
    • For tub/shower enclosures, install the steam head 6 inches above tub top ledge.
    • When used in shower stall with acrylic or other nonheat-resistant floors, install the steam head 20-30 inches from floor or use a steam shield MS-103412.
  2. If the steam room is provided with seat(s), locate the steam head as far away from the seat as possible.
  3. Install the steam head with the steam-emission slot facing downward.
  4. Note: To preserve steam head finish, do not use a wrench or other tools to tighten. Hand tightening is sufficient when Teflon or equal pipe thread sealing compound is used.
Drain - (1/2" NPT)

Note: A drain valve is provided to facilitate servicing.

Where local codes permit, provide a drain line connection from steambath generator drain valve. Check plumbing code for receptor, trap and vent required. Unit drains by gravity.

Safety Valve - (3/4" NPT)

Where permitted by local codes, provide a discharge connection for the safety valve.

Warning: To ensure proper and automatic safety valve operation, do not connect a shutoff valve or a plug to safety valve outlet.

Electrical

All electrical wiring to be installed by a qualified electrician in accordance with local and national codes.

Power Wiring
  1. Check power voltage. Use 240V rated-unit when supply is greater than 208V. (Most homes have 240V, 1PH service).
  2. Use minimum 90 degree C/300V copper conductors only, sized in accordance with local and national electrical codes.
  3. Connect the equipment grounding wire to the ground terminal provided.
  4. Install a separate circuit breaker between the supply and unit.
  5. On single-phase units, use two-wire supply source with ground. Neutral (white) wire is not required.
