How to Select Generator Size
Step 1. Determine cubic footage of steam enclosure: multiply LENGTH inches x WIDTH inches x HEIGHT inches
to find cubic inches. Divide cubic inches by 1728 to determine cubic feet.
Step 2. Find steam enclosure size within the ranges shown on the chart for the supply voltage
(240 VAC or 208 VAC).
Step 3. Consider material and climate: If the steam enclosure is constructed of tile or marble or if the steam
enclosure is against poorly insulated outside walls in a cold climate, select the next higher or highest kW
size of steam generator available. Natural stone such as marble may reduce the cubic cpacity by as
much as 50%.
Electrical Requirements
All SteamPro generators operate at 208 or 220 to 240 VAC at 50 or 60 Hz. Circuit is to be single phase 3-wire (two
conductors at line voltage and one ground conductor must be provided). Bond the SteamPro generator with a #8
minimum gauge solid copper wire from the bonding clamp at the unit to the house electrical panel or approved local
ground. An approved ground may be an 8 foot long ground rod (3 meter length earth rod), a plate electrode, or other
acceptable bond. Check your local building code for requirements.
Caution:Without proper grounding and bonding, a system malfunction may cause fatal shock.

INSTALLATION
Locating the Steam Generator
The steam generator must be installed upright and level. The steam generator must be located within a 25 foot
maximum steam line run to the steam head AND within the 25 foot control wire length to any controls. It may stand
attached to a horizontal base or to a wall. For wall mounting, use “keyhole” slots on a cabinet back to slip over screw
heads and install a wood cleat or shelf to the wall at the bottom of the unit to help support the bottom. Add a cleat at
the top to keep the unit in place.
Install the steam generator indoors only and in a dry location that will not be subject to freezing. If exposure to
freezing can not be avoided (e.g., seasonal-use homes), the optional automatic tank drain down valve must be
installed. Turn off the power and water supply to the unit if it will not be used for an extended period of time.
Room Construction and Ventilation: Important
The room in which the steam generator is to be located must be constructed of materials that can withstand excessive
amounts of moisture and condensation. Large amounts of steam can be released into the room when the enclosure
door is opened. Providing natural or forced ventilation of the room will help maintain comfort and minimize moisture
damage to the building. Jacuzzi Whirlpool Bath is not responsible for damage resulting from excessive moisture.
Consult an architect or engineer for aid in designing your room structure.

Plumbing Instructions and Cautionary Notes on Installation
Minerals in the water or poor water quality can shorten the life of the steam generator or cause erratic operation if
the tank is not drained regularly. Drain the tank frequently. Jacuzzi Whirlpool Bath also strongly recommends
purchasing and installing the optional drain down valve. See the important note below. The tank will be drained
automatically after each use after the water temperature lowers. Water filters and other conditioners are strongly
recommended if the water is of poor quality.
Guard against possible contact with hot steam pipes and other plumbing.
Maximum run of the steam pipe is 25 feet. The steam pipe should be insulated. This will reduce condensation in
the steam line and will increase efficiency. Use only copper and brass pipe and fittings, 1/2 inch minimum.
Install a water supply shutoff valve where it is easily accessible.
The water supply pipe should be attached to cold supply. Do not use a saddle or piercing type connection for the
steam unit water supply.
Apply thread compound sparingly to fitting threads such that excess compound does not dislodge and restrict the
copper pipes or filter screen. Flush lines before making connections to the generator.
When tightening or loosening fittings, always use a backup wrench to hold the adjacent fitting.
Caution: Do not install any valves or create restrictions in the steam line. Do not construct any dips or valleys
in the steam line as condensation will accumulate in these and block the pipe with water. Pitch the steam line
such that condensation will run to the steam generator (preferable) or to the steam head.
Important Note About Tank Drain Selection:
Jacuzzi Whirlpool Bath strongly recommends purchasing and installing the optional Automatic Tank Drain Valve
for the steam generator. This drain valve prevents standing water from remaining in the tank between uses.
The Automatic Tank Drain Valve must be installed where the steam generator may be exposed to freezing
temperatures, e.g., in seasonal-use homes. (Water supply lines and water solenoid valve must not be allowed to
freeze.) This option prevents standing water from remaining in the tank. The tank will be automatically drained
through this valve when the water has cooled.
Read all warranty provisions before selecting a manual drain valve or the automatic drain down option.
