Doc. No: 81128 Page 4 of 16 Rev G 1/17 JWJ
Installation Requirements
1. Use copper or brass fittings only. NEVER USE GALVANIZED FITTINGS!
2. The water inlet, steam outlet, and pressure relief valve, require brass unions.
3. The generator must be upright, accessible and on a level surface with all connections on
the back. The Access Panel (top and front of unit), as well as rear of the unit must be
unobstructed and allow for easy access.
4. Unit may be installed up to 50 feet away from shower area.
5. Do not plumb a trap in the steam line or plumb the pressure relief valve into the steam line.
6. Pitch steam line back towards generator avoid perfectly level plumbed lines.
7. Before connecting water line to the generator, flush water line into a five-gallon pail to remove
any silt or other materials that may be in the line. A ThermaSol 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
Refer to Figure 2A for the following:
1. Connect tee to the hot or cold water line. Install copper pipe or tubing to the tee. If an in-line
filter is to be installed on the water line to the generator, (which is suggested), it would be
preferable to install the tee on the cold water line.
2. Install a brass shut-off valve on the water inlet line in an accessible area prior to the brass
union and recommended in-line water filter.
3. Before making the last connection to the 3/8” water inlet line coming to the unit, flush the
water line into a five-gallon pail to remove any silt or other materials that may be in the line.
4. Make the final connection and turn on water. All ThermaSol generators are equipped with an
automatic water fill system. The water will stop after unit is filled.
IMPORTANT: MAXIMUM WATER PRESSURE IS 70 P.S.I.
