Empty and Flush Entire System

(new system or end of job)

NOTE:

•

If the system includes heaters and heated hose,

turn them off and allow to cool before flushing.

Do not turn on the heaters until the fluid lines

are clear of solvent.

•

Cover fluid containers and use the lowest possi-

ble pressure when flushing to avoid splashing.

•

Before color change or shutdown for storage,

circulate the solvent at a higher flow rate and for

a longer time. Change the solvent when it gets

dirty.

•

To only flush the fluid manifold, see Flush Mix

Manifold, Hose, and Spray Gun, page 30.

•

If the machine is inoperable, use drain plugs on

the pump inlet fittings.

Guidelines

Flush new systems if the coating materials will be con-

taminated by mineral oil.

Flushing will help prevent materials from settling or gell-

ing in the pumps, lines, and valves. Flush the system

when any of the following situations occur.

•

anytime the system will not be used for more

than one week (depending on materials used)

•

if the materials used have fillers that will settle

•

if using materials that are moisture sensitive

•

before servicing

•

if the machine is going into storage, replace the

flush solvent with light oil. Never leave the

equipment empty of any fluid.

Procedure

1. Follow Prime Empty System, page 25 and Flush

Mix Manifold, Hose, and Spray Gun, page 30, as

required.
