INSTRUCTION MANUAL
3.2 Pump Installation
WARNING: WHEN LIFTING THE PUMP, USE AN APPROPRIATE CRANE (OR A
!
HOIST) AND LIFT SYSTEM.
CHECK POSITION AND TIGHTNESS OF LIFT SYSTEM SO THAT WEIGHT OF THE PUMP
IS NOT UNBALANCED.
FAILURE TO OBSERVE THIS PRECAUTION CAN RESULT IN SERIOUS ACCIDENTS.
CAUTION: BEFORE INSTALLATION CHECK ROTATION.
!
CORRECT ROTATION IS CLOCKWISE WHEN VIEWED FROM TOP OF MOTOR.
READ ELECTRICAL WIRING.
(1) When installing directly on the floor.
1. Clean the installation area.
2. Under no circumstances should the cable be pulled
while the pump is being transported or installed.
Attach a rated lifting chain or strap to the pump
lifting bail and install the pump.
3. This pump must not be installed on its side. Ensure
that it is installed upright on a secure base.
4. Install the pump at a location in the tank where
there is the least turbulence.
5. If there is a flow of liquid inside the tank, support the
cable where appropriate (See Fig. 6).
6. Install piping so that air will not be entrapped. If
piping must be installed in such a way that air
pockets are unavoidable, install an air release valve
wherever air pockets are most likely to develop.
7. Do not permit the end of discharge piping to be
submerged, as backflow will result when the pump
is shut down.
8. Non-automatic pumps (model DLFU, DLMFU) do
not have an automatic operating system using built-
in floats. Do not operate the pump for a long time
with the water level near the minimum operating
level as the automatic cut-off switch incorporated
inside the motor will be activated.
