CHECK THE BILL OF LADING FOR THE WEIGHT BEFORE LIFTING. ONLY USE APPROPRI-
ATE LIFT METHODS AND EQUIPMENT TO MOVE OR HANDLE SAM PUMP KIT OR MOD-
ULE. (TYPICAL PUMP KIT WEIGHT IS APPROXIMATELY 1200 LBS. (545 KG) TYPICAL
MODULE WEIGHT IS 2800 LBS. (1270 KG)
ELECTRICAL POWER TO THE VALVE MOTOR SHOULD BE DISCONNECTED BEFORE OP-
ERATING THE VALVE PHYSICALLY USING THE MANUAL OVERRIDE HANDWHEEL.
OPERATORS SHOULD FIRST BE TRAINED TO OPERATE THE FIRE PUMP MANUALLY (US-
ING PUSH BUTTONS, CONTROL RODS, AND MANUAL [NOT ELECTRICAL] VALVE OVER-
RIDES.)
•
AUTOMATION ONLY MITIGATES PROBLEMS AROUND THE PUMP AND VALVES
• OPERATORS NEED TO UNDERSTAND HOW TO DIAGNOSE PROBLEMS
•
SAM MANAGES PROBLEMS BY HELPING TO KEEP THE PUMP SAFE BUT IF AN
INADEQUATE WATER SUPPLY OR PUMP CAVITATION OCCURS THE OPERATOR
MUST UNDERSTAND WHAT IS HAPPENING AND CORRECT THE PROBLEM
•
SAM DOES NOT ADJUST FOR FRICTION LOSS ON HOSE LINES OR PUMPING AT
ELEVATION
•
SAM MAINTAINS PRESSURE SETTINGS BASED ON SENSORS MEASURING
PRESSURE NEAR THE DISCHARGE VALVE
•
THE SYSTEM CAN NOT ALLEVIATE STATIC PRESSURES
•
RESIDUAL PRESSURE IN THE SYSTEM MAY BUILD IN THE DISCHARGE
LINES WHEN THAT PARTICULAR LINE IS NOT FLOWING WATER OR NOT
FLOWING ENOUGH WATER TO BE GATED
•
THE OPERATOR MUST BE AWARE THAT THIS PRESSURE MAY PRESENT
A DANGER TO LARGER DISCHARGES. (THEREFORE, SETTING A
SMALLER DISCHARGE LINE AT A PRESSURE HIGHER THAN YOU WOULD
EXPOSE A LARGER HOSE [OR LARGER DISCHARGE] TO IS NOT RECOM-
MENDED)
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.
ALWAYS FOLLOW LOCAL GUIDELINES FROM THE AHJ AND THE APPARATUS MANUFAC-
TURER.
ALWAYS FOLLOW PROPER OPERATING PROCEDURES. THE PUMP OPERATOR MUST BE
FAMILIAR WITH THE PUMP AND SAM OPERATING INSTRUCTIONS AS WELL AS OTHER
OPERATING GUIDELINES FOR THE APPARATUS AND ACCESSORIES.
