area. If this is not possible, contact your local dealer or call the factory so we can provide longer cables.
3. Do not install the steam generator inside the steam room, outdoors or in an unheated attic or basement where water could freeze.
4. Select a location that is dry and will enable access for future servicing.
Steam Room Design Co
nsiderations
1. Steam room must be completely enclosed
(sides, top and bottom).
2. All inside surfaces of the steam room must
be covered with a waterproof surface such as
ceramic tile, fiberglass, molded acrylic,
cultured marble, etc.
3. Ceiling and seats inside the steam room
should be sloped to allow condensation to
run off and prevent dripping on the bather.
A ceiling slope of 2" per foot should be
adequate.
4. Ceiling height should not exceed 8 feet. To
minimize the ceiling height, it may be
necessary in some installations to slope the
ceiling from the center.
5.
A floor drain should be installed for cleaning
and allowing water drainage. For safety, a
non-skid flooring should be used.
6. Vents inside the steam room are not

Plumbing Instructions
WARNING!
Never shut off the water to a steam generator that is in use. All plumbing should be installed by a licensed plumber and must
comply with all local and national codes.
Place the steam generator in the location selected for installation. Make sure that the
unit is level and in an upright position.
Steam Outlet
1. Inside the steam room, select the best position for the steam head as far
away from any seating area as possible and drill a 7/8" diameter hole.
It is
recommended that the hole be drilled 12" above the shower floor or 6"
above the rim of the tub. Please refer to Figure 4.
When used in a shower
stall with acrylic, fiberglass or other non-heat resistant floors, please
consult with the manufacturer of the product for the best location of the
steam head.
2. At the steam generator, connect the 1/2" copper adapter and 1/2" copper
union to the steam line on the top of the steam generator. Please refer to
Figure 5A.
Important: The 1/2" copper union must be installed to
facilitate future removal of the generator.
3. Run a 1/2" copper steam line from the steam generator to the steam room.
Terminate the steam line with a 1/2" C x FIP Hi Ear female adapter and
secure to a structural member. Stub out into the steam room with a 1/2"
brass nipple.
Do not use black iron or galvanized pipe. They will rust and discolor the
wall of the steam room. The steam line should be sloped slightly toward
the steam generator paying close attention not to allow any kinks or dips
where steam may collect and condense, blocking the flow of steam. The
steam line can run up, down, or horizontally, but it cannot run down and
then up.
4. Insulate the steam line for best results.
5. Inside the steam room, seal around the brass nipple with 100% silicone
caulk. Slip the escutcheon over the brass nipple and connect the steam
head with the slots facing down. Care must be taken not to scratch the
steam head or escutcheon with a wrench.
Pressure Relief Valve
1. Install the pressure relief valve in the fitting on the top of the steam
generator. Please refer to Figure 5A.
The pressure relief valve outlet must
drain in accordance with local and national codes.
Important: The 3/4" copper union must be installed to
facilitate future removal of the generator. To ensure
proper and automatic safety valve operation, do not
connect a shut-off valve or plug the safety valve outlet.
Drain
1. A 1/2" brass nipple and cap is provided on the back end of the steam
generator to facilitate servicing. The cap can be removed and the nipple
can be used as a drain or flush.
A. Manual Flush.
Attach a 1/2" copper adapter and 1/2" copper union to the
1/2" brass nipple. Attach a ball valve and run a 1/2" copper water line to
the cold water supply. Tee off the elbow of the water line and attach a
second ball valve and run 1/2" or 3/4" copper drain line. Please refer to
Figure 5A.
The ball valve on the water supply can be manually opened
allowing water to flow into the steam generator. any loose
particles inside the steam generator will be flushed out the
steam head and into the steam room..
After the steam generator has been flushed, close the ball valve
on the water supply side and open the ball valve for the drain.
All water and any loose particles inside the tank will be
drained. After the water has drained out, close the ball valve
and the tank will remain dry until the next steam bath.
A bucket will suffice, however, if a floor drain is used, the
drain must be connected in accordance with local and national
codes, paying close attention to the codes for receptor, trap and
vent required.
B. Auto Drain. Attach the Leisure Steam auto drain to the steam generator
following the instructions on page 8. R
un a 1/2" or 3/4" copper drain line
to a gravity flow drain. The auto drain opens automatically after each
steam bath allowing the water and any loose particles from inside the
steam generator to be drained.
The drain must be connected in accordance
with local and national codes, paying close attention to the codes for
receptor, trap and vent required. See Figure 5B.
Important: The manual and auto drains drain by gravity.
Avoid any upward slope of the drain line, otherwise,
sediment will collect and prevent proper draining and will
damage the steam generator.
Water Supply - Important: Water pressure should not exceed 50 PSI.
1. Connect a tee to the cold water supply and run a 1/4" copper water line to
the steam generator. Install a water shut-off valve near the point of
termination. do not use a saddle valve or piercing type of valve for the
water shut-off valve.
2. Where hard water is a problem, the Leisure Steam filter, LS-FILTER, is
recommended. This filter will help remove the calcium and magnesium,
the main components in hard water that cause scale buildup. This will
prolong the life of your steam generator, allowing you to enjoy many
years of trouble free use.
3. Flush the water line thoroughly to remove any debris that may be in the
line.
4. Connect the 1
/4" copper water supply line to the 1/4" compression fitting
on the water inlet fitting on the top of the steam generator. When
tightening this fitting, always use two wrenches so there will be no strain
on the water inlet valve.
5. Turn on the water slowly and check all connections for leaks.

C. Have the electrician connect the two wires from the auto drain valve to the two (2) red wires located inside the junction box.
2. Connecting the drain line to the auto drain valve.
A. Run a 1/2" or 3/4" copper drain line to a gravity flow floor drain. The copper drain line must be pitched down, away from the steam
generator.
Important: The auto drain drains by gravity. Avoid any upward slope of the drain line, otherwise, sediment will collect and prevent proper draining
and will damage the steam generator. The drain must be connected in accordance with local and national codes, paying close attention to the codes
for receptor, trap and vent required.
3. Operation of the auto drain.
A. The auto drain valve is a normally closed valve that stays closed for the entire steam bath. The valve remains closed for 20 minutes after
the steam bath and then is automatically opened allowing the water and any loose particles from inside the steam generator to be drained.
Note: In addition to the above operation, all Digital Control steam generators are programmed to flush the inside of the steam generator tank for 3
minutes after the initial drain period. After the 3-minute flushing period has elapsed, the drain will stay open to completely drain any residual water
in the tank.
B. The valve is then closed on all models and the tank remains dry until the next steam bath.
4. Testing the auto drain.
A. After all of the plumbing and electrical connections are made, turn the steam generator on and listen for the water filling the tank. When
the water stops flowing, turn the steam generator off.
B. Automatic Test. Wait the 20 minute period to see that the valve opens as designed.
Manual Test. Move the manual opening lever on the auto drain over the stop and push it slowly and firmly to the "MANUAL
OPEN" position. The stop permits the valve to be locked in the open position.
C. The water should now drain out. Make sure that the water does not back up or splash out of the floor drain. Correct as necessary.
D. Return the opening lever to the "AUTO" position.
