STEAMHEAD INSTALLATION

1. For steam rooms constructed of tile, marble or similar non­porous heat-resistant materials for the enclosure, locate
steam head 12 inches above steam room floor and install
Mr.Steam PN CU-103985 acrylic shield on each steamhead.

IMPORTANT: For Steam rooms using acrylic, fiberglass or other
non-heat resistant materials used for steam room enclosure, in­stall each steamhead 20-30 inches above the floor.

2. Locate each steamhead away from bather seating area and
away from traffic patterns as required to prevent incidental
contact with steamhead or direct steam emissions.

3. NOTE: To preserve the steamhead finish, do not use wrench
or other tools to tighten. Use of proper thread sealant and
hand tightening is usually sufficient.

4. Apply a bead of silicone around the steamhead where it
meets the wall as required to prevent moisture damage.

ACRYLIC SHIELD

Apply a small bead of silicone in the grooves on the top and bot­tom of the steamhead. Place an Acrylic Shield (PN 103985) over the
steamhead until the tabs engage the grooves in the steamhead.

STEAM SOLENOID VALVE INSTALLATION

The steam solenoid valve is powered by the CU Steam Genera­tors 120 VAC control circuit.

• The steam solenoid valve:

• Should be plumbed as close as practical to the steam room

• Must be installed outside the steam room

• Must remain accessible for service

• Shall be plumbed horizontally
