SERVICE CONNECTIONS:
ELECTRICAL CONNECTION: Junction box for electrical con-
nection for boiler heat and controls.
DRAIN: Condenser box, compartment and boiler, 11/2" NPT.
(Provide an open air type drain within 12" of condenser box and
for best results at a distance so that steam vapors will not enter
the steamer from underneath the control area. Do not connect
solidly to any drain connections.)
COLD WATER CONNECTION: 1/2" NPT for boiler feed. Inlet
water pressure between 20 and 80 psi.
COLD WATER CONNECTION: 1/2" NPT for condensate box.
Inlet water pressure between 20 and 80 psi.
WATER: For swing faucet, (single) (dual) temperature, 1/4" IPS
tailpiece.
STEAM TAKE-OFF CONNECTION: 3/4" NPT.
WATER QUALITY STATEMENT:
The fact that a water supply is potable is no guarantee that it is suitable for
steam generation. Your water supply must be within these general
guidelines:
SUPPLY PRESSURE 20 - 60 psig
HARDNESS* less than 3 grains
SILICA less than 13 ppm
TOTAL CHLORIDE less than 4.0 ppm
pH RANGE 7-8
UN-DISSOLVED SOLIDS less than 5 microns
*17.1 ppm = 1 grain of hardness
Other factors affecting steam generation are iron content, amount of
chloridation and dissolved gases. Water supplies vary from state to state
and from locations within a state. Therefore it is necessary that the local
water treatment specialist be consulted before the installation of any
steam generating equipment.
NOTE:
•Dimensions which locate the above connections have a tolerance of
+ or -3" (+ or -75 mm).
•Installation of backflow preventers, vacuum breakers and other specific
code requirements is the responsibility of the owner and installer. It is
the responsibility of the owner and installer to comply with local codes.
•Plastic drains are not recommended due to inherent limited tempera-
tures of the plastic. Boiler purge temperatures may exceed 180°F. The
installer may be required to provide means to reduce boiler purge water
temperature to be that of the condensate temperature of 140°F or less.
•This appliance is manufactured for commercial installation only and is
not intended for home use.
