Oil Change

*Please make sure to drain current oil and replace drain cap before flushing oil is used.

Remove the fill cap. 

Add flushing oil until the level is at the half-way mark on the sight glass. Replace fill cap. 

Run the pump by either opening and closing the lid, or manually pressing the micro switch located at the back right of the chamber. 

After 15-20 cycles, the pump should be warm and the oil should have been circulated through out. The more cycles ran, the better the oil can flush the moving parts of the pump. 

If the flushing oil becomes thick or milky during this process, please drain and refill with new flushing oil. Once the flushing oil that is drained after completing a flush looks similar to the oil that was added, it is more than likely clean. 

Remove drain plug and drain flushing oil from the pump. Replace drain plug.

Remove fill plug and refill with operating oil. Replace fill plug and reassemble.

 

 

During the vacuum process, the oil becomes contaminated due to moisture in the products packaged.

These contaminants can settle to the bottom of the oil, creating a wedge between the vane, rotor and cylinder.

This wedge will bind the pump making it impossible to turn and cause the pump to overheat or seize.

Oil, when compared to the cost of a new vacuum pump, is very inexpensive. Vacuum pumps require the proper lubrication to operate efficiently. During applications that involve vacuum sealing liquid items, some may hinder the condition of the oil by adding moisture or contaminants and reacting to process gases to form sludge. Regular oil monitoring, as well as regular oil changes can help prevent this. We also recommend running the conditioning program on a weekly basis or as needed. A conditioning program warms up the pump to operating speed in an effort to burn off moisture.

There are 3 possible causes of leaking oil in a vacuum packaging machines. 

1. The oil was overfilled. The oil should only be at the half way mark in the sight glass.

2. The machine was tilted or layed on its side. 

3. The pump or filter is clogged.

The conditioning program ensures that the pump is thoroughly rinsed. During the program the pump and oil reaches operating temperature so that the oil can better absorb any moisture and contaminants and filter them. The high temperature enables any moisture in the pump to evaporate minimizing the risk for corrosion in the pump.

MVS20:

The program lasts 15 minutes and it is advisable to run it at least once a week. Turn on the machine, press the key conditioning program and close the lid. The program runs automatically. During the program the display will show moving dots. The program can be interrupted at any time using the stop key. It is important for the program to complete a full 15 minute cycle and advisable to only interrupt the cycle for something urgent.

X Models:

Use P09- Set the vacuum at 99.9% and Extra Vacuum to E30.

Run machine for 5-10 cycles to warm up the pump assembly and help burn off and filter contaminants. 

XP Models:

Toggle to the second page in program 1 by using the "S" button, where you will see advanced functions "VE SA CP AS SI IC LT" along the bottom of the display. Use the down arrow to highlight CP and press the left or right arrow key. This should add an "X" underneath the CP option. Close the lid and this will start a 4 minute condition cycle.

We recommend the following:

If the room where the machine is located is under 60 degrees Fahrenheit, use a 15 weight non detergent oil for all machines. 

If the room where the machine is located is over 60 degrees Fahrenheit, use a 15 weight non detergent oil for table top units and MVS 52 115V.

If the room where the machine is located is over 60 degrees Fahrenheit, use a 30 weight non detergent oil for swing lid models and floor models.

As the pump cools, the moisture and contaminants start to separate in the pump and when drained, the contaminants cling to the walls of the pump, causing the new oil to quickly become contaminated when added.

Vacuum sealers perform best when good oil conditions are maintained. Not keeping up with routine oil changes will cause damage to the pump assembly and incur unnecessary expenses. Following our recommendations of preventative maintenance will prolong the life of your machine.

We recommend to change the pump oil on your vacuum sealer based upon the following packing:
 
  •  Wet/Damp Products: every 3 - 6 months
  •  Dry/Solid Products: every 9 - 12 months

This is just a standard guideline. Oil change is dependent on use, but clear oil should be visible in the sight-glass, located on the rear of the machine. Oil that is dirty or has visible debris must be changed immediately. 

Oil can be murky or emulsified, and this is normal. Emulsified oil is a sign that a conditioning cycle needs to be run.

Before draining out the oil, we recommend to run a couple of cycles to warm up the oil.

  1. Carefully remove the machine back cover using the supplied 2.5mm hex wrench.

  2. Carefully remove the lower oil fill plug using the supplied 5mm hex wrench.
    Caution: Have a catch basin under the machine for the oil to drain into and dispose of used oil according to regulations.

  3. Replace the lower oil fill plug tightly.

  4. Carefully remove the upper oil fill plug using the 5mm hex wrench.

  5. Add non-detergent pump oil until it reaches the middle of the sight glas on the pump.

  6. Replace the upper oil fill plug tightly.

  7. Carefully reassable the removed machine back cover using the 2.5mm hex wrench.

  8. Turn power switch to the ON position and cycle the vacuum sealer a minimum of three times.

  9. Calibrate the vacuum sealer before operating to assure proper vacuum pressure levels.

If there is oil in the chamber, there are two possible reasons why:

  1. Check oil level. It should be at the half way mark in the oil-sight glass of the pump. Over -filling the reservoir can cause "back-suction" from the pump and "shoots" the oil into the chamber during air release. Also, we recommend replacing the filter after every oil change. A clogged filter could also cause oil to "shoot" into the chamber.

  2. If the machine was tilted or laid on it sides, oil can move in to the hoses and components. This oil can "shoot" itself into the chamber during the air release cycle. Please keep machine leveled.
