Minipack Torre Mv31 Pump Manual

The MiniPack MVS 31X vacuum packing system is a chamber style vacuum machine. A commercial vacuum packer that is small enough to fit into a home kitchen. A nice SousVide choice, also popular with sportsmen for the ability to change the depth of the unit with multiple plates.

The next video gives a brief description of the new MVS31X the new changes and style. The unit comes standard with a cut off wire and heat wire for poly bags. If you are looking for a unit to use with retort canning or mylar bag sealing the MVS31X still lends it's self for this application but does need to be upgraded with a heavier duty heat bar by PMG for this function. This is not a factory upgrade exclusive only via PMG.

The shorter chamber size evacuates a bit faster. However sealing larger bags for items such as roasts or whole chickens the chamber is a bit small in the new MVS31X. We recommend the larger chamber of the Sammic 310S for home or commercial applications that have a need for a larger item to be vacuum sealed. The overall foot print of the two units is approximately the same but the chamber size in the Sammic is several inches longer, giving it more room for larger items.

Busch 7 Meter Rotary Oil Pump for a fast cycle time and quick air release making this a higher production unit the MiniPack MVS26.

Gas Flush SystemGas Flush Option can be added at the time or order. Gas flush feature is used for products that need the air removed from the bag, but are delicate in nature not wanting the tight squeeze of the bag caused by vacuum packing. The gas flush option allows for the operator at a touch of a button to go from traditional vacuum packing to gas flush, the bag is injected with a nitrogen, or combination of gases to give the bag a pillow effect but be void of oxygen. A great Feature for pastries and or some vegetables will stay fresh and crispy but not crushed. This option is rarely used on meats with the exception of fresh Tuna as it enhances the color without harmful ingredients and dyes. We suggest PraxAir for your gas supplier, as they are experts in the field for proper amounts of gas and the food you are working with.

Liquid TrayThe Optional Liquid Tray will slope the chamber to seal bags of liquid like sauces.

Vacuum can be started up quiet easily from just a small touch from the lid to the micro-switch, to adjust the lid. Loosen up screws from the back of the lid on both the left and the right side.

The display fuse on an MVS 45 is located on the side of the contactor labeled QM2.

Many applications being used contain liquid when vacuum sealing inside the chamber. We always recommend that an angel tray kit for liquids is used.

To assist in keeping these liquids from entering the bladder, we have added 2 'O' Rings to the bushing.

These 'O' Rings serve as a gasket to help protect the bladder. A photo of the new style bladder bushing can be found below.

A clog in the oil cooler or oil tubing, prevents the proper circulation and can cause many problems.

To determine if there is a clog, check the temperature at the oil tubing coming from exhaust box, down the back end to the round oil cooler.
The temperature taken at the oil tubing should be about the same (+- 10 degrees) as the temperature measured at the side of the exhaust box.

If there is a big difference in the 2 temperatures, it may indicate there is a clog.

1. Lid switch or start button starts the vacuum cycle.
2. Control board sends signal to the vacuum pump to start pulling out all the air from the chamber.
a. The air release valve (normally closed setup) is opened to the vacuum pump and closed to the
atmospheric pressure.
- this is to ensure the final vacuum pressure is attainable
b. The seal valve (normally closed setup) is closed to the atmospheric pressure and open to the vacuum pump.
- this is to prevent the seal bladder from pushing the seal bar upward and pinching the bag
3. Vacuum sensor on control board receives final vacuum pressure and control board sends stop signal to
vacuum pump.
4. Control board sends out signal to seal valve and seal transformer for the set seal time.
a. Seal valve receives signal to open to the atmospheric pressure and pressure difference pushes bladder up and raises seal
bar against seal cushion.
b. At the same time seal transformer receives signal and energizes the seal wires to seal the bag.
5. Control board sends signal to air release valve to open to atmospheric pressure.
a. Pressure in the chamber and outside equalizes; spring in bladder retracts to bring seal bar down
Lid can be opened.
6. Control board sends signal to air release valve and seal valve to close for the next vacuum cycle.

1. If the machine is not equipped to receive gas and the gas function is programmed, the machine will not work. The gas flush function light will blink continuously until it is reset to zero.
2. Gas or gas mixture must be regulated between 15 to 60 psi before connecting to the gas inlet on the machine.
3. The higher the pressure, the higher the force or velocity of gas will come out of the nozzle. High pressure can move the bag from the nozzle or the sealing bar or cause the bag to be crooked on the seal bar.
4. If bag contains powdery substance, the gas injection may cause the powder to expand and over flow out of the bag and into the chamber.
5. Gas flush function can be set from program P1 through P8 on the MVS X series machine.
6. During programming mode, each light will light up to accept the programming.
a. Vacuuming – picture with arrow pointing out of the package( left most LED light on the keypad)
b. Extra vacuum – using the same picture with arrow pointing out of the package
c. Gassing – picture with arrow pointing into the package
d. Sealing – picture of 2 triangles on top of each other at opening edge of package
e. Air release – picture of arrows pointing toward outside the package (right most LED light on the keypad)
7. The vacuum % must always be higher the gas %.The residual vacuum % between vacuum % and gas % should be higher than 60%. This is to ensure proper sealing of the package.
8. Example 1.
a. Vacuum 99.9%
b. Gas 40%
c. Residual vacuum = 99.9 – 40 = 59.9%
9. Example 2.
a. Vacuum 75%
b. Gas 15%
c. Residual vacuum = 75 -15 = 60%
10. Over-gassing will only waste the gas inside the chamber. Choose the lowest gas % possible to give the best pillow effect of the package.
11. Nozzle should be inside the bag and the bag holder under the lid should be over the nozzle. This will ensure the bag is pinched between the holder and the nozzle when the lid is closed.
12. The bag should also lay flat with no wrinkle and no fold-over on the seal bar for a good seal.

If the air is not returning to the chamber at the end of the cycle, please check the following if you are a certified technician or electrician:

1. On the keypad, does the fourth LED light come on when air is supposed to be returning to the chamber?

If no, it is more than likely your control board.

If yes, the possibilities include:

Check the connection from, control board to wire harness.

Check the 2 wires that go to the air release solenoid as they should measure 120V.

If they are not measuring at 120V, control board is more than likely the issue.

If they do measure at 120V, check voltage at the solenoid connector, make sure it measures 120V.

If the voltage at the solenoid connector does not measure 120V, possible bad connector or loose wire.

If the voltage at the solenoid connector measures 120V, check the devac valve solenoid by hot wiring directly with 120V power.

If it engages the valve, the valve is good.

If it does not engage the valve, the valve and solenoid need to be replaced.

On all MVS floor model series (50, 52-208v and 65) lines are numbered L1, L2 and L3.

For all 3 phase MVS floor model series, connect high/wild leg to LINE 3.

1. Check oil and filter. Not regularly changing your oil can negatively affect the way in which your pump runs.

2. Check that safety switches have not been triggered. If you can push in any of the buttons underneath the front right corner of the machine back up, this means one of them has been triggered due to a power issue.

3. Make sure there is a set value in the vacuum percentage in the program you are using.

4. If there are lights blinking on your display, more than likely you have programmed gas. Make sure if you are not using inert gas and that the values displayed are 0.

5.Manually press on the micro lid switch on the back of the chamber to see if that is the issue.

6. Try to recalibrate the machine.

For technicians-

Check microswitch, contactor, all connector wires, control board, and fuses(both on the control board and at fuse box).

In cold environments, the oil becomes heavy, causing the amp pull to become higher.

We suggest to increase the breaker to an 18 AMP breaker.

Moisture working its way into the bladders is what can create the majority of issues that lead to bladder replacement.

Minipack Torre Mv31 Pump Manual Instructions

Minipack highly recommends to use an angled tray for liquids to prevent these issues from occurring and decrease oil contamination. Order an angled tray for liquids today to prevent bladder issues.

Other possible issues:
The sealing bar on the machine has one of the following symptoms:

Loss of continuity
Loss of bag vacuum
Inconsistent sloppy seal
