- Check that the current input does not exceed the value indicated
on the motor-variator data plate.
7. M INTEN NCE
C UTION !
before any operation, switch off the pump(s).
No special maintenance in operation.
Keep the pump and the motor-variator perfectly clean.
In case of prolonged stopping, if there is no risk of frost, it is best not to
drain the pump.
The bearing holding the coupling and the motor bearings are lubri-
cated for their total lifetime and do not require any lubrication.
On pumps equipped with greaser under bearing box, see regreasing
instructions written on sticker put on it:
On other models, the bearing holding the coupling is lubricated for its
total lifetime.

DEFECTS DETECTED BY THE SPEED V RI TOR
ll incidents hereafter mentioned give rise to :
- The resting of the "available transfer" relay.
- The activation of the "failure transfer" relay when the maximum
quantity of defect is reached.
- ligthening of a red LED.

- The "failure transfer" relay is active when the counter
reaches 6 failures.
1) If the pump is completely stopped and an intervention on
this one is necessary, cut the supply ; correct the failure,
switch on the supply again.

It is recommended to grease the shaft end as well as the coupling
boring with a high adhering grease (type D321R Molikote or 8191
Loctite for example) to facilitate any further diassembling.
The mechanical seal does not require any maintenance in opera-
tion. It must never operate dry.
Replacement frequencies
Remark : these are only recommendations, the replacement fre-
quency depends on the operating conditions of the unit , i.e. :
- Temperature, pressure and type of the conveyed fluid for the
mechanical seal.
- Load and ambient temperature for the motor and the other com-
ponents.
- Starting frequency : continuous or intermittent running.

a) Check that the cooling channel is not obstructed.
b) Dismantle the pump, replace the defective components or clean.
c) Dismantle the pump, clean it and replace the defective parts.
Possibly mechanical defect of the motor (bearings). Clean all the pipe-
work.
d) Limit the maximum loading point of the pump according to the type of fluid.
a) Check the voltage at the converter terminals.
b) Check the supply.
c) Dismantle the motor-converter of the pump and check it or replace it.
a) Check that the cooling channel is not obstructed and that fans run cor-
rectly.
a) Clean the cooling ribs of the motor.
c) The motor / converter is foreseen to run at a maximum ambient
temperature of + 40 °C.
2) If the failure cause has been suppressed without cutting
the converter supply ; the pump must start again after an
impulse on the "reset" button (See FIG. 4).
- If the defect is major, the action of an after-sales technician
is required.
