USING
Be sure the installation is correct to make the product performance best. All the materials
have passed strict inspection. Install correctly could keep the pumps from damage and ove-
loading. Failure to do as instruction could result in damage for which we decline all
responsibility.
all models must bu used within the hight scope marked on the nameplate. If the hight is too low, the motor will
e overloaded and emaged.
Installation
The pump must be totally submerged which will provide it with neccessary be submerged which will provide it
with the neccessary cooling.
Install the pump away from the bottom to avoid dirt blocking the wet end, if use the pump in the water tank
with a lot of dirt.
Never use electric wire or pipe to hang the pump. Ensure there is enough space for the free operation of the
float switch.
Assembly of the discharge pipe
It is recommended to install a pipe with larger diameter than the discharge outlet to reguce the friction loss a
much as possible. Install a check valve to the outlet of the pump to prevent pipe from emptying each time pump
stops. Avoid twisted or curved routing of the pipework and ensure correct connection at outlet. In both cases
flow at outlet will be reduced if the connection is wrong.
Electric cennection
Motor with single phase had been installed with thermal protector. For three phase pumps, protection should be
provided by the user.
Inspection before starting
Ensure that the voltage and frequency are the same as those shown on the motor specification plate.
Ensure the capacitor are the same as the pump´s requirement. Ensure the pump is totally submerged into the
water.
Check the direction of the rotation. Never make the pump operated dry.
Never modify the float switch position, which is adjusted by the manufacutrer.
