Dimension

PLUMBING

General

• All plumbing shall be performed by a qualified licensed plumber and in accordance with applicable National and local codes.
• Use unions on all pipe connections as required for service and removal of the steam generator.
• Use only brass piping or rigid copper tubing. Use only piping as permitted by codes.
• Do not use black, galvanized, PVC pipe or PEX except as noted.
• Water supply and steam piping must be flushed to remove flux and other debris prior to connecting the steam generator. Failure to flush the steam piping may result in blockage or an inoperable system.

WATER SUPPLY (3⁄8″ NPT)

• Install a shut off valve in the water supply line.
• It is recommended to install a strainer in the water supply line.
• Install an anti-water hammer device as required.
• Install an approved backflow preventer as required by local codes.
• Connect the generator to a cold water line.
• Water feed line may be flexible copper tubing, braided hose, PVC or PEX if permissible by local codes.
• Do not overheat inlet solenoid valve with solder connections. Overheating will damage parts and may result in a water leak.
• Flush inlet water line thoroughly before making connection to the generator.
• To reduce operating noise, reduce feed water pressure to between 15 – 20 psi is recommended. Optional pressure reducing valve part number 104198.

DRAIN (1″ NPT)

• Do not connect the generator drain line to an undersink trap.
• Do not drain into a steam enclosure or any location where accidental contact with drain water may occur.
• Do not connect the drain valve to the steam piping. Connecting the drain line to the steam piping may allow boiling water to discharge through the steamhead causing a scalding hazard.
• A drain valve is provided to facilitate maintenance and servicing. Provide a drain line connection from steambath generator drain valve according to National and Local Codes.
• Check local plumbing code for receptor, trap and vent requirements.
• Do not connect Drain line and Safety Valve line together.
• The steam generator drains by gravity. Plumb all drain lines accordingly.
• See Condensation pan instructions for installation of the optional Condensation Pan.

SAFETY VALVE

Where permitted by local codes, provide an outlet plumbing connection for the safety valve.

• To insure proper and automatic safety valve operation do not connect a shut-off valve or a plug at the safety valve outlet.
• Do not connect a shut off valve or any obstruction to the safety valve.
• Do not connect the safety valve output to the steam piping.

STEAM PIPING

Note : Some CX systems have multiple generators. Each steam generator must be plumbed separately to a dedicated steam line and dedicated steam head.

WARNING

• Do not install any valve in the steam piping. The flow of steam must be unobstructed.
• CX Steam Generators must be installed with one or more steamheads per generator. Two steam heads per generator is recommended and will result in reduced noise. For installations of tandem CX Steam Generators, each generator must be installed with one or more steamheads.
• Never use less than 3⁄4” steam piping from the generator. Using less than 3/4” steam piping will result in increased velocity of steam coming out of the steam heads and may result in scalding and personal injury.
• Install steam piping as required (including routing, fittings and length of pipe) to ensure an equal amount of steam reaches each steam head. Unequal steam piping will result in too much steam coming out of one steam head and may result in scalding and personal injury.

CAUTION

• Use a brass pipe or copper tubing from unit to the steam head as permitted by codes.
• Insulate steam piping with fibreglass pipe insulation or similar insulation rated 212° F or higher.
• Pitch steam piping 1/4″ per foot towards the steamhead or steam generator to avoid valleys and trapping of condensate. Running the steam piping down and then up will create a steam trap blocking or restricting the flow of steam.
• Models CX1600 to CX5000 are made of multiple steam generators. Each steam generator must be plumbed separately to a dedicated steam line and dedicated steam head.

Failure to pitch the steam piping as required for condensate to drain, may cause condensate to block the flow of steam. Blocking the steam flow may cause steam pressure to discharge boiling water through the steam head, resulting in a scalding hazard. Blocking the flow of steam may cause steam to discharge through the safety valve, resulting in a scalding hazard.
For the optimal distribution of steam, steam heads should be spaced evenly throughout the steam room.

STEAMHEAD INSTALLATION

• For steam rooms constructed of tile, marble or similar non-porous heat-resistant materials for the enclosure, locate steam head 12 inches above steam room floor and install MsSteam PN 103938 acrylic shield on each steam head.
• Locate each steam head away from bather seating area and away from traffic patterns as required to prevent incidental contact with steamhead or direct steam emissions.
• Install each steam head with steam slots facing to the left and right as shown in the diagrams.
• Apply a bead of silicone around the steam head where it meets the wall as required to prevent moisture damage.

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.

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.
Do not use with fragrance containing aldehydes. Acrylic Shield damage may result. MrSteam oils are approved for use with this acrylic shield.
