5. MAINTENANCE
The electropump can only be dismantled by specialised, qualified personnel.
Any modification without prior authorisation relieves the manufacturer of any kind
of responsibility.
All repair and maintenance jobs must be carried out only after having
disconnected the electropump from the power mains.
For electropumps with tank, check periodically that the pressure inside the tank is
0.2 bar lower than the minimum calibration pressure of the pressure switch.
To check,
disconnect the autoclave from the electric power mains and discharge the hydraulic
system (the pressure gauge supplied with the pump must indicate zero ).
The replacement of the power cable must be carried out using a cable of the
same type with the same ending.
In the case of electropumps without a cable, provide power cables type
H05 RN-F for internal use and type H07 RN-F for external use, complete with plug.
6. PROBLEMS
1.
The motor does not start and makes no
noise.
Check the electrical connections.
Check the protection fuses.
2. The motor does not start but makes a
noise.
Check the state of the capacitor.
Check the electrical connections.
Check for obstructions in the pump or
motor.
3. The motor turns over with difficulty.
Ensure that the voltage is sufficient.
Check for possible rubbing between
moving and fixed parts.
4. The pump stops occasionally.
Tripping of the motor protector (single-
phase version) due to excessive
current absorption.
5. The pump does not deliver.
Check
priming.
Check the direction of rotation.
Foot valve blocked.
6. The pump does not prime.
The suction pipe or the foot valve are
taking in air.
Check the slope of the suction pipe.
Check filling of the pump body.
7. The pump flow rate is insufficient.
Suction pipe with insufficient diameter.
Check the correct direction of rotation.
Foot valve or impeller blocked.
8. The pump vibrates and makes a noise.
Check that the pump is firmly secured.
The pump is working outside its plate
data.
