INSTALLATION INSTRUCTIONS
(Continued)
WARNING: Disconnect the power supply to the appliance before
cleaning or servicing.
Make electrical connection through the 1-1/8" (29 mm) diameter hole provided using 3/4" (19
mm) trade size conduit. Refer to the wiring diagram located inside the right side panel. Use
90°C minimum insulated wire.
PLUMBING CONNECTIONS
WARNING: Plumbing connections must comply with applicable
sanitary, safety, and plumbing codes.
The water supply inlets are provided with 3/8" (10 mm) compression fittings for 3/8" O.D.
copper tubing. The water supply line pressure should be 25 - 50 psi (170 - 345 kPa) for each
line. The water supply to the generator tank is separate from the water supply to the cooling
system where steam is condensed before entering the drain line.
Install line strainers (not provided). A manual shutoff valve for each supply line must be
provided convenient to the steamer.
We recommend treated water feeding the boiler inlet supply, and untreated water feeding the
cooling system inlet. Hook-ups are labelled on the back of the steamer.
ADJUSTMENT FOR HIGH ALTITUDE LOCATIONS
The steamer has been factory set so that when it is ON, and during the READY phase, it will
maintain water temperature in the steam generator tank at approximately 205°F (96°C) (just
below water boiling point). However, for high altitude locations, an authorized service agency
must adjust the steamer to achieve this temperature.
ADJUSTMENT FOR DRAIN WATER TEMPERATURE
Cooling solenoid valves have been adjusted to yield drain temperatures of 140°F. This will vary
depending on install location water supply temperature and pressure. A qualified service person
should adjust the cooling solenoid valves should the drain temperature be other than desired.
Refer to section 8.0 Service on page 21 for adjustment instructions.
