Pipe and dispose of the exhaust air safely, away from people, animals, and food handling areas.
If the diaphragm fails, the fluid is exhausted along with the air. See Air Exhaust Ventilation in
the separate pump manual 308–553.
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and
result in a fire or explosion and serious injury

The surge tank filter screen may require periodic
cleaning. First, relieve the pressure. Unscrew the
surge tank cover from its base and remove the filter
screen. Clean the screen with a compatible solvent
and reinstall it in the surge tank.
Flush the pump when necessary to prevent the fluid
you are pumping from drying or freezing in the pump
and damaging it. Use a compatible solvent.
An optional Vitonr gasket is supplied for the surge
tank, for use in applications where the standard EPDM
gasket is unsuitable.
Before storing the pump, always flush the pump and
relieve the pressure.

The Graco Warranty and Disclaimers
Graco warrants all equipment listed in this manual which is manufactured by Graco and bearing its name to be free from defects in
material and workmanship on the date of sale by an authorized Graco distributor to the original purchaser for use. With the exception of
any special extended or limited warranty published by Graco, Graco will, for a period of twelve months from the date of sale, repair or
replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment is installed,
operated and maintained in accordance with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or
substitution of non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance or structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.

A
PARTICULAR PURPOSE IN CONNECTION WITH ACCESSORIES, EQUIPMENT, MATERIALS OR COMPONENTS SOLD BUT

switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance
in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract,
breach of warranty, the negligence of Graco, or otherwise.
