Check the quality of supply water as described below before starting
construction of the water supply lines. If a SteamerGard water treatment
system must be installed to achieve acceptable water quality, install it
before connecting the water supply lines to the SteamCraft 3.1.
Contact a local water treatment specialist for an on-the-premises water
analysis. The recommended minimum feed water quality requirements for
the SteamCraft 3.1 are listed in Table 2-2.
Table 2-2. Minimum Water Quality Requirements
Total Dissolved Solids less than 60 parts per million
Silica less than 13 parts per million
Alkalinity less than 20 parts per million
ph factor greater than 7.5
Water Supply System
Select a water supply system that fulfills the requirements of the limits
listed in Table 2-2 The supply must provide a minimum dynamic pressure
of 35 osi (2.4 kg/cm
2
) and a maximum static pressure of 60 psi
(4.1 kg/cm). Refer to page 18 for detailed pressure and fitting
requirements, and recommended plumbing layouts.
• If analysis shows that the supply water is within the required limits, a
single fine water system can be installed. A single water line system is
illustrated in Figure 2-18 on page 18.
• If analysis shows that the supply water is NOT within the required limits,
install a SteamerGard water treatment system. Figure 2-19 on page 19
illustrates a treated water supply arrangement.
• If analysis shows that the supply water is NOT within the required Limits,
and it is not possible to install a SteamerGard water treatment system;
plan on increasing the frequency of maintenance, cleaning, and
descaling beyond that recommended in the maintenance schedule
(Chapter 4).
Selecting The Operating Location
For safe and efficient operation, observe the following criteria when
selecting an operating location for the SteamCraft 3.1.
1. The SteamCraft 3.1 fits in a small counter space. Figure 2-3 illustrates
the dimensions and clearances required. Maintain the following min-
imum dimensions around the unit for safe and efficient operation,
maintenance and service.
• A 3 inch clearance around the unit for ventilation.
• A 12 inch clearance on the right side for removing the service panel
during descaling, maintenance and repair.
• A3 inch clearance at the rear for the water inlet fittings, and the
maximum size (2-inch NPT) drain fittings.
• Approximately 22 inches in front of the unit for opening the door and
cafeteria pan clearance.
