Plumbing Installation Instructions
3. Steam Generator Installation
The Steam Generator should be mounted in a location conve-
nient for hook-up and service by the plumber and electrician.
CAUTION: The Steam Generator is designed to be used
ONLY in an upright and level position; to do otherwise would
damage the unit and void the warranty.
a) The Steam Generator can be mounted to a wall or
set on the floor. However, the unit must be secured.
To secure the unit to a vertical wall, loosen the two
screws holding the electrical access cover, remove
cover (see Figure 1). Located inside the cabinet
near the top left and right corners are mounting
holes. Place top cover back and secure.

piercing type valve for water connection.

described in Section 2 to the ¾" nipple on the Steam
Generator using a union.
