HYDRO-CUSHION

SERVICE CONNECTIONS

General

These service connections are required:

1. Piped inlets and outlets (cold water, hot water, “third” water,

reuse water, flushing supply water, Spray down and/or cool-
down water, steam, central liquid supply, peristaltic pump inlets,
compressed air inlet, vent, reuse and/or drain).

2. Electric power connections (for additional information see “EXTERNAL FUSE AND WIRE SIZES FOR

MILNOR

MACHINES” - MAEFUSE1AE).

Requirements for Piped Connections

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.

MACHINE DAMAGE—Valve bodies will be ruined if twisted and distorted.

☞

Hold the connection side of the valve with a wrench when connecting plumb-
ing.

MACHINE DAMAGE—Piping will be damaged if struck by tilting machine.

☞

Route piping to tilting machines carefully.

Machine Damage Hazards—Pumped chemical systems, if not properly in-
stalled, can cause corrosion damage.

☞

See the reference manual for precautions and additional information before
making any chemical connections.

IT IS NORMAL FOR THE VEGETABLE FIGER
GASKET ON THIS SHELLFRONT TO LEAK
SLIGHTLY WHEN THE MACHINE IS FIRST
COMMISSIONED. IT SHOULD STOP LEAKING
AFTER THE FIRST FEW LOADS ARE PROCESSED.
