GEA ARIETE - Oil Filters Change; Vapour Condensate Discharge

Niro Soavi S.p.A
VAPOUR CONDENSATE DISCHARGE
Inside the crankase it is possible to have condensation of vapours depending
on the characteristics of the ambient where the machine is working in, therefore
it is necessary to remove regularly the condensate to avoid any mixing with
lubricating oil.
The frequency of the discharge depends on the amount of condensate formed
in the drive unit (which depends on the working temperature, relative humidity,
frequency of starting and stopping the system); however, refer to the "Tables for
Regular Servicing", chapter 4.2.
The condensate drain can be done when the machine is stopped for at least 4
hours.
To drain the condensate:
- Prepare a basin for collection and open the drain valve at the bottom of the
lubricating unit
- Water is heavier than oil, therefore it is collected at the bottom of the oil
tank; once the oil starts to pour out, close again the drain valve
- Check the oil level again and, if necessary, top it up through the filler plug
Presence of water into the oil may be caused by cooling water entering trough
the crosshead seals; it is recommended to check the surface of crosshead
extensions for scratches, and to replace the crosshead seals in case of oil
leakage or oil into the water, according to what is mentioned in paragraph 4.8.1.
OIL FILTERS CHANGE
Oil filters change is extremely important to guarantee proper and reliable
operation of the lubricating system.
It is therefore necessary to replace or cleand the oil filters each change of oil as
recommended on the periodical maintenance indications.
The delivery side filter is of “spin-on” disposable cartridge type; the suction side
filter is of metallic mesh and is placet inside the tank (figure 4.9.1, item B).
If the intake filter is of the type "with disposable cartridge", it should be replaced
as often as indicated in the "Table for Regular Servicing", paragraph 4.2.
The filter is equipped with an internal by-pass valve: this opens when the
pressure drop due to clogging exceeds a preset level, bypassing the filtering
element.
To replace the filter cartridge it is necessary to empty the complete lubricating
circuit:
- Remove the spin-on filter cartridge with suitable too (not supplied)
- Install the new filter cartridge after having lubricated with oil the gasket
