Frequently Asked Questions - MMPP4302-PKG Micro Matic

How do I clean the Micro Matic MMPP4302-PKG pump?

After each use, flush the system with warm water. For deep cleaning, use a food-grade sanitizer and follow the manufacturer's instructions. Do not use abrasive cleaners.

What types of beer can I dispense with this pump?

The MMPP4302-PKG is compatible with most draft beers, including lagers, ales, stouts, and craft beers. Ensure the keg is properly pressurized.

How do I connect the CO2 regulator?

Attach the CO2 cartridge to the regulator, then connect the regulator to the keg's gas-in post. Adjust the pressure to 10-15 PSI for optimal flow.

Why is my beer foamy?

Foam can be caused by high pressure, warm beer, or dirty lines. Reduce the pressure to 10-12 PSI, ensure the beer is cold (38-40°F), and clean the faucet and hose.

Can I use this pump with a jockey box?

Yes, the MMPP4302-PKG can be integrated with a jockey box for portable cooling. Connect the output hose to the jockey box coil inlet.

How often should I replace the O-rings?

Inspect O-rings every 6 months and replace them annually or if they show signs of wear. Use Micro Matic replacement O-rings for proper fit.

What is the maximum keg size this pump handles?

The pump supports standard keg sizes up to 1/2 barrel (15.5 gallons). For larger kegs, ensure the pump is securely mounted.

Does the pump require a power outlet?

Yes, the pump needs a standard 110-240V AC outlet. It draws 150W, so ensure the circuit can handle the load.

Can I use the pump without CO2?

No, the pump requires CO2 pressure to push beer from the keg. Without CO2, the pump will not dispense properly.

How do I troubleshoot if the pump doesn't start?

Check the power connection, ensure the fuse is intact, and verify that the CO2 tank has pressure. If the motor hums but doesn't run, the pump may be airlocked. Bleed air by opening the faucet.

INSTALLATION AND OPERATION

1. Remove packaging from the unit in the vicinity of the area where it will be installed.
2. Carefully lift the unit into the desired position.

NOTE: DO NOT PUSH UNIT - damage will be caused to the legs if the unit is pushed into position.

75' UNIT

1. Connect one of the glycol tubes to the pump outlet. Insulate any exposed tubing.
2. Connect the second glycol line to the pump outlet. Insulate any exposed tubing.
3. Carefully push the glycol bath lid to one side, allowing sufficient space to fill the bath with liquid.
4. Inspect the bath for debris.
5. Fill the glycol bath with Micro Matic Polar Flo glycol solution (mixed 2 ½ parts water to 1 part glycol). Fill the bath to the fill level on the glycol level indicator.
6. Connect unit to the electrical outlets capable of handling the required voltage loads. This should be carried out by suitably trained personnel and comply with all state and national electrical codes.
7. Glycol level will fall as glycol is pumped through the glycol lines. Continue to fill the bath to the fill level on the glycol level indicator.
8. Replace top cover.
9. Inspect for any leaks.

125', 250', AND 500' UNITS

1. Remove the refrigeration deck from the unit.
2. Inspect the glycol tank for any debris.
3. Connect one of the glycol lines from the beer python to the pump outlet. Insulate any exposed tubing.

NOTE: In units with more than one pump, connect a glycol line to each pump outlet.

1. Connect the second glycol line from each circuit to the glycol bath inlet.
2. Fill the glycol bath with Micro Matic Polar Flo glycol solution (mixed 2 ½ parts water to 1 part glycol). Fill bath to the level of the fill line on the glycol level indicator.
3. Replace the refrigeration deck.
4. Connect the unit to the electrical outlets capable of handling the required voltage loads. This should be carried out by suitably trained personnel and must comply with all state and national codes.
5. Glycol level will fall as glycol is pumped through the glycol lines. Continue to fill the bath to the fill level on the glycol level indicator.
6. Inspect for any leaks.
7. Temperature of the glycol outlet will drop slowly to 30 °F.

NOTE: To adjust the glycol temperature please see Adjusting the Electronic Thermostat.

ELECTRONIC TEMPERATURE CONTROL WITH DISPLAY

NOTE: When the unit leaves the factory the electronic thermostat is pre-set to the following parameters:

Temperature Scale: F (Farenheit)

Setpoint: 30 °F

Differential: 3 °F

Operating Mode: C1 (Cooling)

NOTE: To ensure the correct operation of your unit these parameters must be adhered to.

NOTE: The Keypad Lockout switch must be in the "UNLOCK" position (factory setting) before adjusting the control. If the keypad is locked, pressing buttons has no effect on the control. The Keypad Lockout switch is located on the back inside of the front cover. If necessary, remove the cover by loosening the four captive cover screws.

Changing Temperature Units

1. Press Set button once to display temperature unit.

2. Press the Up or Down button to toggle between °F and °C.

3. Continue pressing and releasing Set button until tank temperature is displayed in normal operating mode ("S1" not flashing).

Setting the Setpoint

Before setting the setpoint, be sure the control is set to the temperature units you want to use, Celsius or Fahrenheit.

To view and adjust the setpoint, use the following method:

1. Press the Set button twice to display Setpoint ("S1" flashing).
2. Press the Up or Down button to adjust Setpoint.
3. Continue pressing and releasing Set button until tank temperature is displayed in normal operating mode ("S1" not flashing).

NOTE: If no entries are made for thirty (30) seconds, the control reverts back to the tank temperature display.

MAINTENANCE

1. Inspect the unit monthly to ensure that the glycol level is maintained to the fill level.
2. If the level is low replace with a Micro Matic Polar Flo glycol solution, (mixed 2 12 parts water to 1 part glycol).
3. If there is evidence of ice build up in the unit, allow the ice to melt and replace all the water/glycol solution with a fresh solution.
4. The glycol/water solution should be changed every 2 years. In regions of high humidity considerations should be given to replacing the solution on an annual basis.
5. Check and clean the condenser fins every 6 months.
6. Check that there is adequate air flow through the unit ensuring enough space all around and that there are no obstructions in front of the air flow vents.
7. Check the condition and effectiveness of the trunk line insulation.
8. At regular intervals, to be determined by the owner, the unit should be checked for electrical safety.
