Attention!
Do not run dry!
If the pump is allowed to run dry, the bearings, sleeves,
and other components could be damaged and serious
overheating of the motor windings can occur.
Attention!
Avoid rapid temperature changes!
Large changes in temperature must be avoided. Rapid
changes can cause leaks to occur in gaskets. Published
procedures for proper heating and cooling must be fol-
lowed. If published procedures are not available, check
with Teikoku before operating the equipment.
Caution!
Hot – Do not touch!
Motor and pump can be hot, even when pumping cold
liquids.
Caution!
If motor trips, do not restart before determining the
cause!
Restarting the motor before ascertaining the cause may
result in excessive heat, causing pump or motor failure.
Hazard!
Do not remove internal bolts in terminal box.
If it is necessary to remove the terminal box for any reason,
first loosen the bolts by 2 or 3 turns to check if any internal
pressure or liquid is present. You must take measures if the
possibility exists that the gas or liquid is toxic or hazardous
to personnel or the environment.
Hazard!
Do not remove any bolts on pump, motor, or drain
plugs!
The internal pressure can be higher than the atmosphere.
Ensure that the pump and motor are properly de-pressur-
ized and decontaminated prior to performing any work.
Proper protective measures must be taken if the possibility
exists that the gas or liquid is toxic or hazardous to person-
nel or the environment.
Hazard!
Always assume that there is liquid left in the pump!
There is always the possibility that residual liquid could
remain in the pump and motor in spite of thorough de-
contamination. Pay particular attention to the clearance
between the shaft and the impeller, bearings, sleeves,
bearing housings, internal bolting and gaskets. You must
take adequate precautions to protect personnel and the
environment if the liquid could be considered hazardous.
