System Installation and Service Instructions
Page 7
Boiling water may be discharged from
the drain. Use materials rated for
boiling water.
Draining the tank into the Steam
Room may present a scald hazard
and /or damage materials used to
construct the Steam Room.
Electrical shock hazard. Disconnect
all electrical power before servicing.
Do not put a shut off valve in the
steam line. Avoid traps and valleys
where water could collect and cause
a steam blockage. The hot steam
line must be insulated against user
contact.
To reduce the risk of explosion, do
not interconnect steam outlets. A
separate steam line must be
provided for each steam outlet.
Centering the steam pipe is critical
in rooms made of plastic, acrylic,
resin, fiberglass or similar
materials. Allowing the steam pipes
to touch materials not rated 212° F
or higher will result in damage to
these materials.
Install the steam head to avoid
potential user contact.
Do not install the steam head near
bench(es) or where condensation
will drip on the user or puddle as
this puddling will present a scald
hazard.
The steam pipe entry into the Steam
Room and the steam head must be
caulked to avoid damage caused by
steam leakage into the wall.
The pressure relief valve must be
installed in such a fashion that the
risk of scalding is reduced to a
minimum. Draining the pressure
relief valve into the Steam Room
may present a scald hazard.
WARNING
1. Install steam head insulator: Fill in gap (using
100% Silicone caulk between steam pipe and fin-
ished wall surface at point of entry (see diagram 12).
Apply silicone caulk to the finished wall side of the
steam head insulator (see diagram 19) and screw on
hand tight until it is flush with the wall with the
opening pointing down. If a hand tight fit does not
align with the opening pointing down, use teflon tape
on the steam line threads to adjust the fit.
2. Install steam head. Slide the steam head on until
it rests firmly against the finished wall. Tighten the
hex head screw underneath the steam head to secure
it in place with the allen wrench provided. The steam
head should be level with its fragrance reservoir at
the top. See diagram 12.
SEE DIAGRAMS 11, 12 & 13
SECTION 4C: INSTALL STEAM HEAD
SECTION 4D: INSTALL PRESSURE RELIEF VALVE
SEE DIAGRAMS 1 (PREFERRED INSTALLATION) 14, 15 & 16
SECTION 4E: INSTALL DRAIN LINE(S) AND DRAIN VALVE(S)
1. Automatic drain valves (ADK) or manual drain valves must be supplied for each
individual generator unit.
2. Generator drain lines may be ganged together AFTER each individual drain but
should not be ganged previous to the drain valve.
3. No generator should have more than three (3) 90 degree bends (elbows or tees)
between it and the corresponding drain valve.
4. Drain valves should be within ten (10) feet of the corresponding generator's drain
nipple.
5. If the automatic drain valve (ADK) option is installed it must be within three (3)
feet of the corresponding generator.
6. Install the 3" nipple (supplied) into drain outlet on generator.
7. Attach the automatic drain (ADK) and/or the manual ball valve to the drain nipple.
8. Install a 1/2" union in the drain line near the drain valves.
9. The drains supplied are gravity flow only therefore all drain lines must be sloped away from
the generator.
10. Plumb the drain line to a drain that meets local and national codes. The water exiting the
drain may be boiling and WILL present a scald hazard. Use materials rated for boiling water.
11. Because of the scald hazard it is highly recommended that the generator not be plumbed to
drain into the shower. Doing so may cause serious injury and may damage shower or steam
facility.
DRAINS MUST BE INSTALLED AND CONNECTED IN ACCORDANCE
WITH ALL PERTINENT LOCAL AND NATIONAL CODES.
Install the pressure relief valve into its port on the Generator. The pressure relief valve outlet must drain in
accordance with local and national codes.
