INSTALLATION
NOTE:
This unit has one power supply for controls and elements, as well as one (1) ground wire. A POSITIVE
GROUND CONNECTION IS ESSENTIAL DO NOT ALLOW ANY TAMPERING OR ADJUSTMENT
OF ANY CONTROL OR WIRING. THE UNIT IS FACTORY SET. ADJUSTMENT OF ANY INTERNAL
COMPONENT OTHER THAN THE FIELD TERMINAL BLOCK CAN VOID THE WARRANTY.
ELECTRICAL CONNECTION NOTE:
All 208-220-240 and 480 volt units will have three (3) terminal block sections. "L1-L2-L3." For use with either 3 wire 3
phase or 2 wire single phase, 50 or 60 Hz.
All 380V and 415V units will have four (4) terminal block sections. "L1-L2-L3-N" for use with European style 4-wire 3
phase with neutral.
THREE PHASE TO SINGLE PHASE CONNECTION:
Be sure that input voltage matches requirement on serial plate. Unit is factory wired for 3-phase, to change to single-
phase. Remove right side panel and re-arrange element lead wires 2 and 3 as shown on sticker inside panel. (Refer to
Figure 2.)
WATER CONNECTION:
Connect cold water line, 1/4" (6mm) NPT into female side of strainer located at right hand lower side of unit as you face
the back of the steamer. Water line pressure should be 30 psi (205 kpa) minimum to 60 psi (410 kpa) maximum.
NOTE:
To facilitate cleaning, plus allow access to rear of unit, flexible connections are recommended.
WATER SPECIFICATION:
To meet warranty requirements supply water must meet the following specification:
Pressure: 30 to 60 psi
Total Dissolved Solids (TDS): 60 PPM
Hardness: 2 Grains or 35 PPM
pH Factor: 7.0 to 7.5
DRAIN LINE:
The drain line connection size from the unit is 1" NPT (32 mm). Position the unit near, but not on top of, an open floor
drain. DO NOT directly plumb to the unit unless you also install an "open funnel" downstream of this connection in the
drain system. Make the drain line from the unit to the air gap above the "open runnel" as short as possible. There should
be no horizontal piping between the unit and the air gap above the "open runnel." The "open funnel" is intended to
eliminate any water from entering
