Service Connections
Required service connections (depending on the machine model and optional equipment) are as
follows:
1. Piped inlets and outlets are as listed in the “Table of Piped Inlets” and “Table of Piped
Outlets.” The sizes and locations of piped inlets and outlets are shown on the dimensional
drawings for the machine.
2. Electric power connections.

Requirements for Piped Connections
1. Inlet pressures must be within the minimum/maximum range specified. Pressures outside of
the specified range may cause the machine to operate inefficiently or malfunction, and may
damage machine components.
CAUTION 1 : Machine Damage
—Valve bodies will be ruined if twisted and distorted.
• Hold the connection side of the valve with a wrench when connecting plumbing.
2. 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, if necessary.
3. If available, use hot water for the supply injector connection. Hot water supply must be 10
PSI minimum (0.70 kilogram/centimeter) and must not contain steam. After making the
connection, set the pressure regulator for a maximum of 28 PSI (1.96 kilograms/centimeter),
when there is no water flow.
4. If valve is accidentally piped to the wrong water line, merely interchange the air tube (if valve
is air operated). Never interchange any electrical connections.
5. Some of the water inlet and/or steam valves on machines may be of the “ball valve”
construction. The flow rate of a ball valve is far greater than that of an equal size globe valve.
Do not use globe type shut-off valves in front of ball valves unless the globe valve is selected
in accordance with the following table.
CAUTION 2 : Machine Damage Hazards —Pumped chemical systems, if not properly
installed, can cause corrosion damage.
• See the reference manual for precautions and additional information before making
any chemical connections.
Table 1: Valve sizes and their equivalents
Ball valve size Equivalent globe valve size
1-1/4" normal flow 2-1/2"
1-1/2" normal flow 2-1/2"
2" normal flow 3"
