Disposing Of The Product; Possible Faults, Causes And Solutions; Technical Data - Espa DRAINEX 400 Manual De Instrucciones

Cleaning the runner:
To unblock or clean the runner, you only need to lift
the suction base. To do so, loosen the fixing screws
(as shown in (Fig. 4)).
Changing the oil:
The oil that lubricates the locks while the pump
operates under normal conditions should be
changed after 3000 h of operation or once a year.
To empty it, dismantle the runner and loosen the T
screw shown in (Fig. 4); and/or remove the lock.
Remember that once the rotating part of the lock has been
loosened, the oil may leak between the friction areas.
To aid extraction of the runner, once you have
removed the fixing screw you can screw in a M10
screw in the thread in the centre of the runner fitted
for this purpose.
The oil used is a white oil of mineral origin with
medicinal quality. The quantity is 0.7 l.
When changing the oil, use one with similar
characteristics that fulfils regional regulations.
If you dismantle the mechanical locks, you are
advised to replace them and change the oil.

8. DISPOSING OF THE PRODUCT

When the pump is eventually disposed of, please
note that it contains no toxic or polluting material. All
