In order to keep your unit working to its best performance at each cycle, it is recommended that you keep a constant and regular maintenance schedule. Here are some tips and tricks to help you preserve your unit for a long time.

Cleaning

Care must be taken to not use a harsh soap or petroleum-based solvent on silicone and plastics.
Never clean the unit with a high-pressure cleaner; the unit, and specifically the electronics can be damaged.

Oil level check

The oil level should be observed on a daily basis and be replenished if it drops below the ¼ or MIN mark of the oil sight glass.

For the models 216 and 219, there is a hole in the back panel of the unit where you can see the oil sight glass of the pump.
For the models 220 and 226, the oil sight glass of the pump can be seen directly at the back of the unit.

All oil level readings should be done only when the pump is turned off. Oil can be added to the oil fill port if the pump is shut off and the circulating oil has sufficient time to return to the oil sump.
Under normal circumstances, it should not be necessary to add or drain oil from the pump between recommended oil changes. A significant drop in oil level means there is an oil leak or that an exhaust filter is broken; in which case the pump should be smoking excessively.

It is normal for the oil to be foamy and light colored in an operating pump.

However, if the oil is milky or dark colored, it is contaminated or burned and must be changed.

Exhaust filtert

Every nine (9) to eighteen (18) months or as necessary replace the exhaust filter element(s).

Lid piston

Over the years, the pressure of the lid piston might decrease to the point that it cannot open the lid properly. The piston can be replaced if necessary. Here is an easy way to replace it if necessary. This method shows you how to easily install the piston without having to force against the piston compression.

Sealing bars

It is strongly recommended to clean the sealing bars with soapy water on a regular basis. An everyday cleaning should be enough to help you keep the sealing bars integrity over the years. If necessary, the teflon tapes which cover the sealing elements can easily be replaced. The sealing elements can also be replaced as well if necessary.

Lid o-ring

Over the years, the lid o-ring might be damaged or might become less tight, giving places to leaks. It is possible to replace the lid o-ring by whether a neoprene or silicone o-ring.

• The o-ring replacement with a neoprene o-ring is fast and easy. This does not require the lid to be removed from the machine. Once the old o-ring is removed from the groove, just slide in the o-ring inside the lid groove. The unit can be used immediately afterward.
  The neoprene o-ring is a convenient replacement part when time is a constraint. The neoprene o-ring has a black color and its materials are composed with foamy cells wich will keep the odor with times. The neoprene o-ring is not used in all types of applications.


• The o-ring replacement with a silicone o-ring requires you to plan a little time of preparation because the lid has to be removed and carefully cleaned. Then a very tiny filet of silicone have to be applied inside the groove before inserting the o-ring.
  The silicone o-ring is durable and the ones installed in our machines are food grade.
