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.
