Flushing The System Before Initial Use - Graco UniDrum C59784 Instructions And Parts List

Operation
Flushing the System Before
Initial Use
Flushing the system before its initial use can prevent
material contamination, which may cause the material
to fail or perform poorly.
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid
contaminating your fluid with oil, flush the equipment
with a compatible solvent before using the equipment.
To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.
NOTICE
There must be a minimum of 10 feet (3 m) of fluid
supply hose on the outlet to prevent damage to the
unit.
To flush the system, perform the following procedure:
1. Select the material for the initial material load.
2. Verify whether the factory-test oil and the initial
material load are compatible:
a. If the two substances are compatible, omit the
remaining steps in this procedure and perform
the Initial System Startup Procedure on page
21.
b. If the two substances are incompatible,
perform the remaining steps in this procedure
to flush the system.
NOTE: Use fluids and solvents that are chemically
compatible with the equipment wetted parts. See the
Technical Specifications sections of all the equipment
manuals. Always read the material manufacturer's
literature before using fluid or solvent in this Pump.
3. Select a drum containing a compatible material that
can dissolve, clean, and eliminate the factory test
20
oil from the system. If necessary, check with the
material supplier for a recommended flush material.
4. Before flushing, be sure the entire system and
flushing drums are properly grounded. Refer to
Grounding the System on page 16.
5. Perform steps 9 through 15 of the Initial System
Startup Procedure on page 21 to load the drum
containing the solvent.
6. Run the flush material through the system for
approximately 1 to 2 minutes.
7. Remove the drum containing the flush material.
