EBARA 25EVMS85.37 Instruction Manual page 4

EVMS/EVMSL
Do not operate the pump with 50 Hz specifications at 60 Hz.
Doing so will overload the pump, causing the motor to burn.
Do not operate the pump with 60 Hz specifications at 50 Hz.
Doing so will cause the pump to perform poorly.
If you have purchased a standard pump, refer to the standard
specifications shown below. The optional specifications indicate
changes made to some pumps to meet the needs of some
customers. Be sure not to operate your pump outside of the
ranges shown in the applicable specifications.
The equipment cannot be used for food-related fluid transport.
In important facilities (computer cooling facilities, freezer cooling
facilities, etc.) always prepare a spare pump for pump failures.
There will be entrainment of cutting lubricant contained in the
piping system, as well as rubber mould releasing agent, foreign
material, etc. Carry out flushing sufficient for the equipment, and
confirm before use.
Make sure that the floor surface where the pump is installed has
been waterproofed and treated for waste water. If it has not,
severe damage could be caused should leakage occur.
Make sure that any one of three terminals of the three-phase
motor is not loose or disconnected. Running the motor with only
two terminals connected could a phase interruption, burning out
the motor.
Pump failures are possible when operated with less flow rate
Caution
than appropriate for the pump size (nominal inlet bore diameter
in mm) (e.g. 50 L/min for size of 50 mm). When operation may
occur with a small flow rate, install relief pipes, etc. to ensure
operation at or above this flow.
If air is entrained during pumping and is not discharged, the
bearings and shaft seals may be damaged, and pumping may
be impossible. Avoid this situation.
Do not touch the pump when the liquid handled is hot water.
Burns may result from high temperatures.
Do not touch the motor. The motor's surfaces will be hot, and
you could get burned if you touch them.
Do not cover the motor with a blanket or cloth. Doing so could
over heat the motor, setting a fire.
To prevent an accident if the pump stops running or an
abnormality occurs, immediately turn off the power switch.
Contact the shop from where you ordered the pump, or EBARA
to perform an inspection and maintenance on the pump.
When the pump is out of use for prolonged periods such as the
wintertime, water inside the pump could freeze, causing
damage to the pump. Accordingly, in such situations, either
drain all water from the pump or provide thermal insulation to
prevent the water from freezing.
Never disassemble the motor. When disassembly is necessary,
contact EBARA.
