Prior to Operation
Check the following points upon receipting of your pump:
Is the pump exactly what you ordered? Check nameplate. It is especially important that you check whether the pump is to
be used with 50 or 60 Hz.
Has any damage occurred during shipment? Are any bolts or nuts loose?
Have all necessary accessories been supplied?
We recommend that you keep a spare pump on hand in case of emergencies. Keep this instruction manual in a place
for future reference.
Check the nameplate for your pump’s head(HEAD), volume(CAPACITY), speed(SPEED), motor voltage and current.
Installation
1.
Check the following before beginning installation.
Insulation resistance measurement:
With the motor and cable (excluding the power supply cable) immersed in water, use a Megger to measure the
insulation resistance between ground and each phase of the motor, and again between each phase of the motor. The
Megger should indicate an insulation resistance of not less than 20mega ohms. While making the measurement, keep
the power supply cable off the ground.
We recommend that an auxiliary pump be kept on hand in case of emergency.

Installation
For automatic operation, pump must be plugged or wired into a remote float switch or liquid level controller.
Installation instructions are included with all our switches and controllers and should be referred to for installation.
Installation and servicing shall be conducted by qualified person I people. Pump will run continuously if plugged
directly into an electrical outlet. Care should be taken to prevent pump running in a dry sump. Pump must be installed
with local plumbing codes. Pump must be placed on a hard level surface. Never place pump directly on clay, earth or
gravel surfaces. Pump can be installed with ABS, PVC, polyethylene, or galvanized steel pipe. Proper adapters are
required to connect plastic pipe to pump. Always install a union in the discharge line, just above the sump pit, to allow
for easy removal of the pump for cleaning or repair. A check valve must be used in the discharge line to prevent
backflow of liquid into the basin. The check valve should be a free-flow valve that will easily pass solids.
Under no circumstances should cable be pulled while the pump is being transported or installed.
Attach a chain or rope to the grip and install the pump.
This pump must not be installed on its side or operated a dry condition. Ensure that it is installed upright on a secure
base.
Install the pump at a location in the tank where there is the least turbulence.
If there is a flow of liquid inside the tank, support the piping where appropriate. 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
such air pockets are most likely to develop.
Do not permit end of discharge piping to be submerged, as backflow will result when the pump is shut down.
Non-automatic pumps have an automatic operating system pump operating water level near the minimum operating level
as the automatic cut-off switch incorporated inside the motor will be activated. To avoid dry operation, install an automatic
operating system, and maintain a safe operating water level (C.W.L.: Continuous Water Level).
For automatic pumps, install the floats as required. The pump may not start if a floats switch touches the wall of the water
tank or the piping. Install the floats so that this will not happen.
