PRO Series Generator Installation Instructions
3 Sizing or Double Checking the Unit Specified
If you are installing the unit or thinking of adding one on your next project,
you will need to make sure the unit is sized properly.
Calculate the shower area
(Length x Width x Height = Cubic Feet)
and confirm the ceiling height does not exceed 8 feet.
The set of numbers in the generator model number
represents the maximum capacity.
Example: Generator model PRO-240 will be sufficient
up to 240 cubic feet (with a ceiling not exceeding
8 feet in height). Up-size 1 Unit size for every foot
over 8 foot to a maximum of 10 foot.
Model number can be found on the box or generator.
Installation note
We do not recommend a
ceiling height exceeding
10 feet.
Lowering ceiling
height to 8 feet helps
create a more efficient
steam room.
ThermaSol’s generators can be placed up to 50 feet from the
shower; in an attic, closet or below a sink are ideal locations.
Make sure the walls, ceiling and floor materials are suitable
foruse with steam.
o All the electrical wiring must be done per National/Local Electrical Codes.
4 Electrical Wiring
The size of the shower will determine the size
of the generator. The size of the generator will
determine electrical requirements.
o Run 240V Power source to the generator.
o Use copper wire only.
o Wire sizes recommended by NEC (2002 Version). Minimum wire
temperature rating 90°C. Type THHN.
o Each generator should be wired to their own separate breaker
8'
4'
5'
o Turn off all electricity to the working area at the main breaker panel!
o Leave power OFF during installation process.
