Installation Guide

1. Determine the System Layout
WARNING: Risk of property damage. Allow a minimum of 12″ (305 mm) of air space around the
steam generator at all times. This provides an area for the heat generated by the unit to dissipate.
IMPORTANT! The minimum required access panel is 24″ (610 mm) L x 15″ (381 mm) H.
NOTICE: The steam generator will perform best when installed as close as possible to the steam head.
The unit should be installed within 25’ (7.62 m) of the steam head.
NOTICE: Large drops in the steam line can increase condensation and reduce the amount of steam
produced. For optimum performance, do not install the steam generator above the level of the steam head.
IMPORTANT! This steam generator must only be installed in the upright position as shown. The pressure
relief valve location must be on top.
IMPORTANT! Contact Kohler Co. Customer Care Center if this steam generator will be installed at an
elevation over 6000’ (1829 m) above sea level. For installation at high elevations the Customer Care Center
will provide instructions on disconnecting the fast start coil.
NOTE: For optimum performance, use 45° elbows in the steam line when possible.
Determine the location of the steam generator. Allow for a 12″ (305 mm) air gap on all sides of the
generator. Allow for a drain pan.
Choose a drain pan appropriate for your installation (KOHLER drain pan is sold separately).
Determine the location of the water supplies and steam lines. Ensure clearance between the steam
line and any surrounding surfaces.
Install this steam generator in a heated space to prevent freezing.
