INSTALLATION
Preparation for operation
1. Read these instructions first.
2. Inspect your pump for shipping damage. Report any
damage to your Berkeley dealer.
3. Fill the engine crankcase with oil, as per the engine
manufacturer’s owner’s manual.
4. Fill the fuel tank with unleaded gasoline (gasoline
engine models), as per the engine owner’s manual.
5. Make sure the suction piping is free of air leaks and is
laid so that there can be no air locks.
6. Fit a strainer to the suction line
Pump Protection
Warranty of these pumps is void unless they are operated
in accordance with this owner’s manual and the
enclosed engine manufacturer’s owner’s manual.
The pumps should be protected from the weather, floods,
chemicals, dust, vermin, insects etc. If the pump has a
fixed location; it should be housed in a weather proof,
well-vented enclosure so that engine heat and exhaust
can escape. When bolted down, flexible mounts should
be used. Depending upon application they may not have
to be bolted down.
Suction
Hazardous Suction. Can trap persons
against suction inlet. Always use strainer on suction hose
to prevent entrapment.
To maintain optimum performance from your pump, the
suction pipe should be:
• Kept to the shortest length possible - place the pump
as close to the water as possible.
• Use reinforced crush-resistant (non-collapsible) hose
or pipe.
• Have all fittings be airtight
• Have flexible pipes rise gently from the water source
to the suction/
• Use inlet port without excessive dips and sharp
angles, to avoid air locks.
• Use pipes equal to or larger than the diameter of the
suction/ Inlet port.
• Use suction strainers to prevent foreign matter enter-
ing the pump.
• Where practicable, use suction floats to aid in the
performance of your pump, by keeping suction away
from the debris on the bottom of the dam or river.
• Ensure that the suction is completely submersed.
