All Models
Unless otherwise specified, field wire electrical
connection is to be 120 volts, 60 Hertz, single phase,
with grounding wire. Connect electrical supply to the
pigtail leads in the supply junction box located next to
the boiler control box for electric generators in a 24"
wide base, and under the boiler control box for all other
generator bases. The supply junction box is located on
the underside of the cabinet top on direct steam

DRAIN CONNECTIONS (Fig’s. 2-12)
Drain connections must be the open air gap type.
Provide a suitable drain under the drain pipes. For
proper drainage, a floor sink with minimum of 12" depth
is recommended.

Before connecting the steamer to water, the water
supply should be analyzed to make sure hardness is
less than 2.0 grains per gallon and pH of 7.5. The water
supply should be clear with no sediment or suspended
material present. If the water supply fails to meet these
standards, it will be necessary to install a water
conditioner on the boiler water feed. APPLIANCE
