Installing the Dual Beer & Coffee Tap Kit

Assembling the D-Coupler for the Beer Keg

The D-coupler is compatible with a single 1/6 barrel keg. Each 1/6 barrel keg holds approximately 5 gallons.

1. Attach the tower to your unit using the screws provided.
2. Hand-tighten the elbow coupler connection to the top (liquid outlet) of the D-coupler.
3. Connect the beer line from the tower to the elbow coupler connection. Use the beer line with the CO2 tank.
4. Connect the gas regulator to its corresponding gas tank (see instructions on page 2):
   • CO2 regulator to the CO2 tank
   • N2 regulator to the N2 tank
5. Attach the CO2 regulator line for beer from the regulator to the gas inlet on the D-coupler.
6. Attach the D-coupler to the beer keg (see instructions on page 2).
7. Place the CO2 / N2 tanks inside the kegerator.
8. Lift the keg by the handles and gently place them inside the unit.
9. Neatly arrange the tubing behind the kegs to ensure the door can close properly. Screw the handle(s) onto the tower tap(s).

The D-coupler connects to the keg via a probe/keg connection and has a control handle.

Installing the CO2 Regulators to the CO2 Tanks

1. Ensure the tower dispenser is closed.
2. Position the D-coupler handle in the upward position to indicate that the keg is untapped (See Figure 1).
3. Ensure the CO2 tank is full (gas tanks are shipped empty).
4. Screw the CO2 regulator on to the CO2 tank valve. Use an adjustable wrench to tighten the nut securely to prevent gas leaks.
5. Connect the gas line to the pressure inlet nipple on the D-coupler and secure it with a clamp. Insert the D-coupler mechanism into the top of the keg and lock it into the lugs with a one-quarter clockwise turn (See Figure 2 & Figure 3).
6. Open the gas tank valves fully to check for leaks by turning the knob counterclockwise.
7. Set the output pressure by adjusting screw on the regulator. Set the CO2 output pressure between 6-12 psi using the pressure adjusting screw on the regulator.
8. Lock the regulator setting by tightening the locknut on the pressure screw.

Note: Higher CO2 pressure will result in more foam; adjust accordingly to achieve the desired pour characteristics.

Attaching the Fully Assembled D-Coupler to the Beer Keg

1. Attach the D-couplers to their respective keg pull the handle out and down until it clicks securely. There will be an audible click, indicating that the gas and keg have been opened and is successfully tapped. (See Figure 4)
2. Position the shut-off lever on the gas line in the downward position to allow the gas to flow. (see image on top right)

⚠️ HANDLE CAREFULLY. Do not jostle or bang keg on the gas canister.

Note: The left regulator gauge indicates total tank pressure.

Installing the N2 Regulator to the N2 Tank

1. Ensure the tower dispenser is closed.
2. Ensure the N2 tank is full. (All gas tanks are shipped empty.)
3. Screw the N2 regulator on to the N2 tank valve. Use an adjustable wrench to tighten the nut securely to prevent gas leaks.
4. Connect the N2 gas line by firmly pressing the ball lock fitting onto the keg's gas inlet until it clicks into place.
5. Connect the coffee line from the tower to the keg by firmly pressing the ball lock fitting onto the keg's liquid outlet until it clicks into place.
6. Open the gas tank valves fully to check for leaks by turning the knob counterclockwise.
7. Set the N2 output pressure to 4–8 psi for flat coffee.
8. Lock the regulator setting by tightening the locknut on the pressure screw.

Attach the CO2 /N2 Tank to the Unit

May vary by tank

1. Remove the bolt with the nut from the tank retainer. Using two screws, attach it inside the unit on the left side of the back wall. Holes are pre-drilled, and screws are included.
2. Slide the tank through the retainer and secure it with the bolt and the nut. Position the tank this way so that you will be able to read the numbers on the gauges and easily access the shut-off valve.

Note: If serving nitro-infused coffee, agitate the keg before serving.
