Doc No. 81159 Page 4 of 17 Rev D 1/17 JWJ
Installation Requirements
1. Use copper or brass fittings only. NEVER USE GALVANIZED FITTINGS or IRON PIPE!
2. The steam outlet is: 1”NPT and requires brass unions.
3. The generator must be upright, accessible and on a level surface with all connections on
the top. The Access Panel (top of unit), as well as the drain access door (lower front of
unit) must be unobstructed and allow for easy access. The Access Panel on the rear of
the unit requires a 36” clearance to access the generator’s heating elements. If the 36”
clearance is not obtainable, the unit will have to be disconnected from the water
supply and moved to allow rear access during unit maintenance. It is best to install the
unit sideways. See the Installation Location Diagram below.
4. Unit may be installed up to 50 feet away from shower area.
5. Master Controller may be installed up to the 100’ of cable run away from the generator.
6. Do not plumb a trap in the steam line or plumb the pressure relief valve into the steam line.
Do not plumb the steam line (pipe) up then down then back up again. This will cause a steam
trap.
7. Pitch the steam line (pipe) back towards the generator. Always avoid perfectly level
plumbed lines.
8. Before connecting the water line to the generator, flush water line into a five-gallon pail to
remove any silt or other material that may be in the line. An in-line water filter is
recommended.
Caution: If the unit is run without water, serious damage may
result! This possible damage is not covered under
ThermaSol’s limited warranty.
Note: Failure to follow specific installation instructions will cause the warranty to be void.
Water Inlet
1. Install a ½” ball valve to a COLD water line. If an in-line filter is to be installed on the water
line to the generator, (which is suggested), do so between the valve and the 3/8”
compression adapter (included) for easy filter service. Place the water pipe outlet within 6” of
the top/left/rear corner of unit.
2. Remove the top access panel with Philips head screw driver.
3. Before making the last connection to the 3/8” water inlet line coming into the top of the unit,
flush the water line into a five-gallon pail to remove any silt or other material that may be in
the line.
4. Make the final connection hand tight then 1 full turn with a wrench. Turn on water. All
ThermaSol generators are equipped with an automatic water fill system. The water will stop
after unit is filled.
5. Thoroughly check for any leaks.
6. Max Water pressure is 70psi. Minimum Water pressure is 40psi. Max Water usage for all
models in less than 1GPM.
