Installation Instructions
4. Use of a dampener is necessary to mini-
mize pulsation at drive elements, plumbing,
connections, and other system areas. The
use of a dampener with Giant Industries,
Inc. pumps is optional, although recom-
mended by Giant Industries, Inc. to further
reduce system pulsation. Dampeners can
also reduce the severity of pressure spikes
that occur in systems using a shut-off gun. A
dampener must be positioned downstream
from the unloader.
5. Crankshaft rotation on Giant Industries,
Inc. pumps should be made in the direc-
tion designated by the arrows on the pump
crankcase. Reverse rotation may be safely
achieved by following a few guidelines avail-
able upon request from Giant Industries, Inc.

6. Before beginning operation of your pump-
ing system, remember: Check that
the crankcase and seal areas have been
properly lubricated per recommended sched-
ules. Do not run the pump dry for extended
periods of time. Cavitation will result in
severe damage. Always remember to check
that all plumbing valves are open and that

Installation of the Giant Industries, Inc.,
pump is not a complicated procedure,
but there are some basic steps common
to all pumps. The following information
is to be considered as a general outline
for installation. If you have unique re-
quirements, please contact Giant Indus-
tries, Inc. or your local distributor for
assistance.

base to a maximum of a 15 degree angle of
inclination to ensure optimum lubrication.
2. The inlet to the pump should be sized for

sary restrictions that can cause cavitation.

If pumps are to be operated at temperatures
in excess of 160oF, it is important to insure
a positive head to the pump to prevent
cavitation.
3.Thedischargeplumbingfromthepump
shouldbeproperlysizedtotheowrateto
prevent line pressure loss to the work area.
It is essential to provide a safety bypass
valve between the pump and the work area
to protect the pump from pressure spikes in
the event of a blockage or the use of a shut-
off gun.
Finally, remember that high pressure operation in a pump system has many advantages. But, if it is

IMPORTANT OPERATING CONDITIONS
Failure to comply with any of these conditions invalidates the warranty.
2. Pump operation must not exceed rated
pressure, volume, or RPM. A pressure relief
device must be installed in the discharge of
the system.
3.Acids,alkalines,orabrasiveuidscan-
not be pumped unless approval in writing is
obtained before operation from Giant Indus-
tries, Inc.
4. Run the pump dry approximately 10
seconds to drain the water before exposure
to freezing temperatures.
1. Prior to initial operation, add oil to the crank-
case so that oil level is between the two lines on
the oil dipstick. DO NOT OVERFILL.
Use Giant Oil # 01154 or the equivalent
SAE 80W - 90 Industrial Gear oil
Crankcase oil should be changed after the
rst50hoursofoperation,thenatregularinter-
vals of 500 hours or less depending on operating
conditions.
