Operation

2.6 Switching Off/Shutdown

Under normal circumstances, all that you need do is to

electrically switch off the TRIVAC-B.

No further measures will be required.

When pumping condensable media let the pump conti-

nue to operate with the gas ballast valve open and the

intake line closed before switching off (see Section

2.5.2).

When pumping aggressive or corrosive media, let the

pump continue to operate even during long non-working

intervals (e.g. overnight) with the intake line closed and

the gas ballast valve open. This avoids corrosion during

idle periods.

If the TRIVAC-B is to be shutdown for an extended peri-

od after pumping aggressive or corrosive media or if the

pump has to be stored, proceed as follows:

When pumping harmful substances, take

adequate safety precautions.

Our technical sales department is available for further

advice in these matters.

Drain the oil (see Section 3.2).

Add clean oil until the oil-level is at the „min“ mark (see

Section 3.2) and let the pump operate for some time.

Then drain the oil and add clean oil until the oil level is at

the „max“ mark (see Section 3.2).

Seal the connection ports. Special conservation or anti-

corrosion oils aren’t necessary.

Please also take note of the information

given in Section 3.9 (storage and storage

conditions).

2.6.1 Shut-Down through Monitoring Com-

ponents

When the pump has been switched off due

to overheating sensed by the motor coil pro-

tector or other monitoring components at

the pump (e. g. thermal sensor), the pump

must only be started manually after the

pump has cooled down to the ambient tem-

perature and after having removed the

cause first.

2.6.2 Failure of the Control System or the

Mains Power

In order to prevent the pump from running

up unexpectedly after a mains power failu-

re, the pump must be integrated in the con-

trol system in such a way that the pump can

only be switched on again manually. This

applies equally to emergency cut-out arran-

gements.
