c. A main disconnect switch and a separate fuse or breaker should be installed near the unit as shown
in Figure 2-6. See Figure 2-1 or 2-2 for the steamers power requirements. Throughout the
remainder of this manual the fused disconnect switch is referred to as the main external power
switch.
d. Refer to the connection diagrams in Figure 2-7, and connect the wires to the terminal block and
ground connector accordingly.
6. Water Supply Requirements and Installation
a. Water Supply Requirements
1). Water Quality
As with any steam generating equipment, poor water quality degrades the performance of the
steamer.
Check the quality of supply water as described below before starting construction of the water
supply lines. If a water treatment system must be installed to achieve acceptable water quality,
install it before connecting the water supply lines to the Gemini Steamer.
If softened or chlorinated water is used in a Gemini steam generator, a carbon type filter must
be used for the water before it enters the steamer to remove Chlorine or other salts. If the water
supply is treated or softened either by the Water Company or on the premises, it may contain
chlorine or various salts. These additives are damaging to the steam generator. Salts and
chlorine used to soften or treat water cause rapid scale buildup, and/or increased corrosion if
allowed to flow into the steamer.
Contact a local water treatment specialist for an on-the-premises water analysis. The
recommended minimum feed water quality requirements for the steamer are listed in Table 2-1.
CAUTION
Using water not within the limits specified in this
manual could void or reduce Cleveland Range’s
warranty coverage of the steamer.
