ELECTRICAL SHOCK HAZARD
POWERMUSTBEDISCONNECTEDATTHE MAIN ELECTRICALSUPPLYBEFOREMAKINGANYCONNECTIONS
1. Use copper or brass fittings only. DO NOT use galvanized or black iron.
DO NOT USE PLUMBERS PUTTY ON ANY WATER CONNECTIONS
2. A union must be installed close to the generator to facilitate easy removal, if necessary.
3. Tap off any existing water supply line, hot or cold, with 1/2” copper tubing or 1/2” NPT pipe.
4. Flush at least 1 gallon of water to clear line prior to connecting to the 1/4” compression water inlet fitting
(A in Plumbing Diagram) on generator. When tightening this fitting, use two wrenches to avoid strain on Water
Solenoid Valve inside generator.
5. Install a shut-off valve (B in Plumbing Diagram) on the water supply line as close to the generator as possible.
DO NOT USE A SADDLE VALVE
6. For best results Install an inline filter between shut-off valve and generator.
7. For best results, steam generator should be higher than the steam head. If this is not possible, steam line must
slope 1/4” per foot minimum to steam room.
8. Connect 3/4” copper tubing or 3/4” NPT pipe to steam outlet (C in Plumbing Diagram) and run to approximately
8-12” off finished floor in shower or just above deck of bathtub on any wall not interfering with user and at least
12-14” away from seat or bench. For areas with acrylic or other non-heat resistant floors, install steam head 20-
30” off finished floor in shower.
DO NOT PLACE A SHUT-OFF VALVE ON STEAM OUTLET LINE, ONLY ON WATER SUPPLY LINE.
WARNING: DO NOT PLUMB VALLEYS AND DIPS WHERE WATER FROM STEAM CONDENSATION IN THE
LINE COULD COLLECT AND CAUSE BLOCKAGE.
9. Leave approximately 1/2” of threads protruding from finished wall. Place escutcheon on threads and screw on
steam head (D in Plumbing Diagram).Take care not to scratch the steam head with wrench. Rotate steam head
until open slot is facing down.
10. IMPORTANT: Steam head must be installed to prevent users from coming into direct contact with the steam head
and the steam coming from it. While in use the steam head and steam coming directly from it will become hot and
can burn. An optional Steam Diffuser is recommended for small steam rooms.
11. Connect 3/4” copper tubing or NPT pipe to the pressure relief valve (E in Plumbing Diagram) and 1/2” copper
tubing or NPT pipe if using an optional Blowdown (F in Plumbing Diagram). Both of these items must be
installed with a union and plumbed to drain to an approved location.
DO NOT PLUMB THE PRESSURE RELIEF VALVE LINE TO THE STEAM LINE OR INTO THE STEAM
ROOM.
