3. MAINTENANCE OPERATING PROCEDURES
This section provides information and procedures for the operation of Hale booster pumps for
the purpose of performing maintenance. Maintenance operating procedures differ greatly from
typical operations. Typical operations are based on the pump being installed in a firefighting ap-
paratus and include pumping from: an onboard tank, or a hydrant, or from draft. Operating pro-
cedures for maintenance purposes include pump performance verification, repair verification,
and troubleshooting and unless otherwise indicated, these instructions apply to all Hale booster
pumps.
THE PROCEDURES IN THIS SECTION PROVIDE ONLY GENERAL/MINIMAL INSTRUC-
TION. DO NOT REPLACE LOCAL PROCEDURES OR POLICIES OR RECOMMENDATIONS
AND PROCEDURES PROVIDED IN THE APPARATUS/TRUCK/UNIT MANUAL WITH
THESE PROCEDURES.
ALWAYS FOLLOW LOCAL GUIDELINES FROM THE AHJ AND THE APPARATUS MANU-
FACTURER.
ALWAYS FOLLOW PROPER OPERATING PROCEDURES. THE PUMP OPERATOR MUST
BE FAMILIAR WITH THE PUMP OPERATING INSTRUCTIONS AS WELL AS OTHER OPER-
ATING GUIDELINES FOR THE APPARATUS AND ACCESSORIES.
A PRESSURE HAZARD MAY EXIST EVEN WHEN THE PUMP IS NOT RUNNING. PRIOR
TO REMOVING HOSES OR CAPS FROM PUMP CONNECTIONS, RELIEVE PRESSURE BY
OPENING DRAINS. BLEEDER VALVES SHOULD ALSO BE USED WHEN CONNECTING
TO AN INTAKE FROM A PRESSURIZED SOURCE.
DO NOT EXCEED OPERATING PRESSURE LIMITS OF PUMP, INSTALLED PLUMBING,
HOSE(S), OR EQUIPMENT IN USE.
OPERATORS, INSTALLERS, AND MAINTENANCE PERSONNEL MUST BE TRAINED AND
QUALIFIED FOR ALL THE ACTIVITIES THEY PERFORM.
FAILING TO REDUCE SYSTEM PRESSURE BEFORE SYSTEM SHUTDOWN OR FLUSH-
ING COULD RESULT IN WATER HAMMERING.
IF IN 30 TO 45 SECONDS ONE OF THE FOLLOWING (BULLETS) DOES NOT OCCUR
STOP THE PUMP AND CHECK FOR AIR LEAKS OR A POSSIBLE PUMP TROUBLE.
•
THE DISCHARGE GAUGE READING INCREASES
•
THE INTAKE GAUGE READING FALLS BELOW ZERO
•
THE PRIMING PUMP DISCHARGES WATER TO THE GROUND
CONTINUING TO RUN THE PRIMING PUMP MAY RESULT IN PUMP FAILURE OR DAM-
AGE.
Utilize the testing provided herein ONLY for the intended purpose. The Repair Verification Opera-
tions procedure (paragraph 3.1) is intended as the initial post repair test for a repaired booster
pump and the paragraphs description explains why. If the pump passes the Repair Verification
Operations procedure proceed with the Pumping From Draft Verification Operations procedure
(paragraph 3.4 on page 23). ALWAYS verify a repaired pumps drafting ability before returning the
pump to service.
