•
Place the pump as near as possible to water source, and
water suction height as low as possible.
•
When lowering the portable fire pump to the ground, lower it
gently and horizontally.
Max. permissible inclination angle: 15°
• In case of the inclined or uneven location, make sure that
water suction hose is lower than suction port of the pump.
• In case of the suction hose is put undulated, air can be left
easily in the hose, and possibly causes suction inability
when the water discharge valve is opened. In this case, set
the water discharge valve half-opened, and operate vacuum
pump until water is discharged continuously (for 3 to 5
seconds from beginning of water discharge).
• Be sure to install strainer and basket on the end of suction
hose. If the pump may suck sand or mud on the bottom of
water source, place sheet below the basket .
• Put the strainer and basket of suction hose into the water
more than 30 cm from the surface to prevent suck of air.
• Discharge hose should be arranged not to be bent.
