･The fire pump must be installed on level ground.
･

Otherwise, an accident may occur.

･

If the fire pump should be installed on uneven ground,
it must be secured.

･Place the pump as near as possible to water source, and

water suction height as low as possible.

･When putting the portable fire pump down on the ground, put

it gently and horizontally.

･In case of the inclined location or uneven ground, 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 cause suction inability when
the water discharge valve is opened.

･In case of the suction inability due to air remaining in the

suction hose, set the water discharge valve half-opened, and
operate vacuum pump until water is discharged continuously.
(More operation of vacuum pump for 3 to 5 seconds from
beginning of water discharge.)

･Be sure to install strainer and basket at the end of suction

hose. If the pump may suck sand or mud of the water source
bottom, place sheet below the basket.

･Strainer and basket of suction hose should be placed more

than 30 cm below water surface to prevent suck of air.

･Discharge hose should be arranged not to be bent.
