CAUTION

The cutout dimensions shown above are based on a 25516 " (64.3 cm) deep counter top. Your counter top may be different than this and require other front to back dimen-sioning. Refer to the product dimensions when determining the required dimensions.

1. If you are installing your keg refrigerator under a counter you will need to drill 5 holes in the counter top to mount the tower. The first hole is a 1 12 " diameter hole located at the center of the tower for the beer line, locate approximately 13 12 " (34.3 cm) from the front edge of the counter top (based on a counter top depth of 25 516 "). Next drill the 4 tower mounting holes per the dimensions. The hole diameter is dependent on the counter top material and if screw anchors are required. The screws supplied are in the literature pack and are a #10 x 1" type AB stainless steel screw. Mark and cut the rectangular cutout for the drain sump. After the holes are drilled and the keg refrigerator is in place under the counter top feed the beer line through the tower gasket, the 1 12 " hole in the counter top and the hole in the top of the keg refrigerator. Mount the tower to the counter top with the 4 screws provided. Place the counter top drain sump, from the literature pack, in the rectangular hole with the radius cutout to the rear around the tower and place the grate in the sump.

2. Mount the regulator to the CO_2 tank (connection B). Note that the regulator has left hand threads and has to be turned counterclockwise to tighten. Tighten with the adjustable wrench or the 118 " open end wrench.

3. Connect the red air line(s) from the regulator to the large air line fitting on the keg coupler with a large hose clamp (connection ⓒ).
4. Connect the clear beer line from the tower to the small air line fitting on the keg coupler with a small hose clamp (connection A).
5. Locate the CO_2 tank in the corner of the refrigerator and secure with the chain. Close the faucet handle on the tower.

USING YOUR BEER DISPENSER

1. Hooking up the keg coupler to the keg: Verify the coupler is in the "OFF" position. Align the lugs on the keg with the corresponding openings on the keg coupler and turn clockwise until the coupler stops (about 90°). Push down and twist the top of the coupler clockwise to allow gas to enter the keg.

Push faucet handle back toward tower to close the faucet

Chain-The chain is fastened and taped to the top of the interior liner. Remove the tape and secure the CO_2 tank in place in the back right corner. Loop chain around top of tank and connect with "S" hook.-

Rotate the top of the coupler counter clockwise to extend the coupler to the to the "OFF" position.

Optional CO₂ tank external mounting bracket:

The optional mounting bracket is designed to hold the 5# CO₂ cylinder that comes with the beer dispenser. Larger cylinders may be purchased from a third party and mounted externally. Use the hole port on the rear of the cabinet to run the CO₂ line to the keg.

Many options are available for mounting the CO_2 tank outside of the beer dispenser to gain additional cold storage space inside.

Secure the optional external mounting bracket on the back of the beer dispenser (this is ideal for mobile units) or mount within adjacent cabinetry (ideal for undercounter built-in units:

Mount the (4) screws (#10-32 x 3/4" flathead machine screws) provided with the bracket in the rear of the appliance. Do not completely tighten. Place the keyhole slots in the flanges of the bracket over the four screws and tighten them to secure the bracket to the back of the cabinet. The bracket can also be fastened to adjacent cabinetry using the provided #10 x 3/4" wood screws.

Mark the hole locations where required using a pencil and the slots in the mounting bracket. Drill appropriate pilot holes (depending on the material you are mounting to) and secure the bracket per the above instructions.

NOTE

The foam insulation plugs provided in the portholes are CRITICAL to proper functioning of the unit and preventing frost build up that can cause damage to the unit and/or refrigerator contents. ALWAYS reseal the CO2 line porthole with the provided insulation plugs once all lines have been properly installed.

NOTE

Consider the length of the red air line when choosing a place for the CO_2 tank. The red air line supplied is 4 feet (1.2 meters) long.

With the gauges mounted to the CO_2 tank place the tank in the mounting bracket.

Remove the foam plug from the hole port, and feed the red CO_2 line through the rear wall and out the coil cover on the inside of the cabinet. Connect the red CO_2 line to the keg coupler.

Reseal the hole in the back of the cabinet with the foam plug.

CAUTION

If the CO_2 tank is placed on the floor it must be secured in the upright position with a chain or other means to prevent it from being tipped over.

Reseal hole around tubing with the foam plug

CO₂ Regulator (Single Dispense Tower)
