Required service connections, (depending on machine model and optional features) are as
follows:
1. Piped inlets and outlets (cold water, hot water, flush water, direct steam, liquid supply and
drain to sewer). The sizes and locations of piped inlets and outlets are shown on the dimen-
sional drawing for your machine.
2. Electrical power connections.

CAUTION: Machine Damage Hazards — Valve bodies will be ruined if twisted and
distorted.
� Hold the connection side of the valve with a wrench when connecting
plumbing.
1. Inlet pressures must be within the minimum/maximum range specified. Pressure outside of
the specified range may cause the machine to operate inefficiently or malfunction and may
damage machine components.
2. A separate flush water valve pressure regulator set for approximately 28 psi (193 kPa) is
shipped with the machine (Figure 1: Flush water valve pressure regulator, page 1 ). Install this
regulator on the flush water inlet when installing piping.
3. Thoroughly flush all water lines before making connections.
4. We recommend installing 40 mesh strainers or filters in front of the cold, hot and third water
valves.
5. When connecting water and steam inlets, always install unions and shut off valves at the point
of connection to permit removal of the machine components for servicing, when necessary.
