Gas Regulator - Marvel ML24BNS2 Installation, Operation And Maintenance Instructions

Gas Regulator (Single Dispense Tower)
Your beer dispenser comes equipped with a 5 pound gas
tank and a single gauge regulator. The gauge reads the
pressure being supplied to the beer keg. Follow the proce-
dure below to adjust the pressure:
12-14 psi for lager beer
9-12 psi for ale's
3-8 psi for still wines
20-40 psi for sparkling wines
To adjust the pressure (Single Gauge):
1. Close the shutoff valve at the bottom of the regulator.
2. Be sure the faucet handle is closed on the tower (see
Figure 47).
3. Loosen the lock nut by turning Q counterclockwise us-
ing the ⁄ " open end wrench until loose, this will allow

adjustment of the pressure adjustment screw.
4. With the flat bladed screwdriver turn the adjustment
screw P clockwise to increase the pressure or Q
counterclockwise to decrease the pressure.
5. Open the shutoff valve on the bottom of the regula-
tor. The gauge reading may drop but will return very
quickly.

Gas Regulator (Double Dispense Tower)
Your beer dispenser comes equipped with a 5 pound gas
tank and a dual gauge regulator. The lower gauge should
be reading approximately 750 psi (52 bar) when the tank is
properly filled and the tank is not in the refrigerator (at room
temperature). The tank will read less when chilled. Use this
lower gauge as an indicator of how much gas you have left
in the tank.
The upper gauge reads the pressure being supplied to the
beer keg. Follow the procedure below to adjust the pres-
sure:
12-14 psi for lager beer
9-12 psi for ale's
3-8 psi for still wines
20-40 psi for sparkling wines
To adjust the pressure (Upper Gauge):
1. Close the shutoff valves at the bottom of the regulator.
2. Be sure the faucet handle is closed on the tower (see
Figure 48).
3. Loosen the lock nut by turning Q counterclockwise us-
