ABOUT
Congratulations on the purchase of your new HOT DRAFT® Tower! This U.S. patented product
(https://kegco.com/pages/patents) is the property of Ryan Bros. Coffee and is the World’s First Draft System that
allows you to enjoy both cold and hot products at the point of dispense without the burning effects of holding tanks or
the lessening of flavor from oxidation. Utilizing a tankless method of just-in-time heating, the structure and flavor
integrity of the beverage is at its original maximum quality without the degradation of heretofore constant reheating.
What does this mean? The HOT DRAFT® Tower delivers constant freshness with zero waste! Inside the keg, nitrogen is
displacing oxygen, keeping the beverage 100% fresh while infusing the beverage with a creamy finish. The finished
product is as good as when it was originally crafted—every ounce and all the time! With the HOT DRAFT® Tower, you
are serving products at their very best...highlighting peak freshness and flavor...and the last ounce is as good as the
first! We hope you enjoy having chosen our innovative solution and for helping us solve the many flavor pitfalls and
waste traditional brewing yields. As you will soon discover yourself—The HOT DRAFT® Tower is “Not Your Same Old
Drip!” ®

ASSEMBLE THE HOT DRAFT® TOWER DISPENSE SYSTEM
Safety Instructions:
1. Pressurized Nitrogen can be dangerous. Handle with care.
2. Never exceed 60 PSI.
3. Always connect Nitrogen tank to regulator. Never connect the tank directly to keg.
4. Keep the Nitrogen tank in an upright position.
5. Ventilate area after Nitrogen leak.
6. The regulator may break if the tank falls on it. Secure the Nitrogen tank.
7. If it becomes difficult to breathe and your head starts to ache, high levels of Nitrogen may be present. LEAVE THE
ROOM IMMEDIATELY.
8. Pressures above 50 PSI will release the coupler’s built-in pressure relief valve.
Attaching the Tower
1. Start by guiding beverage lines and power cable through the hole on the kegerator top. For more than one beverage
line, put the first line through and press the second nut into the hole next to the first tube. Then pull the first tube
from inside the kegerator and it will bring the second nut through the hole. Ensure there is a rubber tower gasket
between the tower and the kegerator top.

2. Once the power cable is inside the kegerator cabinet, (a) guide the cable through the knockout in the back wall and (b)
out the other side.
3. (a) Align the tower flange with the holes on top of the kegerator. Insert the provided Tower Screws into the holes. (b)
Use a Philips Head Screwdriver and appropriate wrench to tighten the screws with provided nuts and washers.

4. Feed the air-cooling line up into the tower.
5. Install the Power Cable Strain Relief Clamp. (a) Slip the Clamp around the power cable. (b) Pinch the ends of the Strain
Relief Clamp close together. (c) Align the holes with the back right Tower Screw. (d) Use the provided nut and washer
to tighten the clamp. (e) Use an appropriate wrench to further tighten the nut and washer until the clamp is shut,
shown in (f).

If you are installing the tower on a surface other than the kegerator top, you must use the necessary hardware to drill
holes for screws and beverage lines. Follow the tower flange dimensions outlined below to match the screw positions on
your surface. Visit www.kegco.com or call [phone] for a printable template.
If installing the kegerator under a countertop, ensure you have the proper amount of air circulation around the kegerator
with no obstructions. If the top of the kegerator touches the bottom of the countertop, seal the gap with caulk or silicone.
If there is a gap between the top of the kegerator and the bottom of the countertop, you can create a spacer using PVC
pipe and seal around that. Drop the line beverage line and power cable through the countertop and spacer and attach the
tower to the countertop.

Attaching the Faucets
When attaching the faucet to the tower, (a) line up the teeth on the inside of the faucet with the teeth inside the shank.
(b) Screw the coupling nut onto the faucet and tighten with the faucet wrench. (c) Screw the tap handle onto the faucet
lever. The lever is an industry standard thread size to allow for aftermarket tap handles.

Gas Connection
The Nitrogen tank will arrive empty, and you will need to have it filled locally. The best way to find a place to fill the tank is
to search for a welding supply store in your zip code. We recommend the use of Industrial Grade Nitrogen for the best
result. Be sure to position the tank in an upright manner.
1. Attach the regulator to the Nitrogen tank. If there is a washer built on to the end of your regulator, you do not need to
use any additional washer. (a) Hand tighten the coupling nut. (b) Use a 1 1/8” wrench to tighten an extra quarter to
half turn. Overtightening the coupling nut may cause a leak.
2. (a) Attach 5/16” I.D. Gas Line Tubing to regulator nipple. The tubing can be made more pliable by heating the end in
hot water. (b) Pinch white plastic clamp into place. (c) Use a pair of pliers to further tighten the clamp.
Note: Ensure the clamp is very tight as this system requires higher pressure than typical beverage systems.

Coupler Connection
Commercial keg couplers attach to both the beverage and gas lines. With this unit, you can use one keg to dispense both
cold and hot beverage by using the provided Low Profile T-Splitter Fitting.
1. (a) Place a neoprene washer between the T-Splitter and the top of the coupler. (b) Attach the T-Splitter to the top of
the coupler. Do not overtighten the T-Splitter as this will cause a leak.
2. (a) Connect the 5/16” ID Gas Line Tubing to a hose nipple on the side of the coupler. (b) Clamp the into place. Use a
pair of pliers to further tighten the clamp.
Note: Ensure the clamp is very tight as this system requires higher pressure than typical beverage systems.

3. Identify the beverage lines. Pull the beverage lines away from the Hot Draft® Tower until they are taut. The beverage
lines will be different lengths. Follow the guide pictured below to identify the lines and corresponding faucet.
Note: The Hot Draft® faucet will dispense hot beverage. Faucet and Faucet will dispense cold
beverage.

4. The beverage lines come with Beer Nuts at the end that attach to the T-splitter. (a) Be sure to insert a neoprene
washer into the Beer Nut before attaching to the T-splitter. (b) Attach the Hot Draft® Beverage Line to one end
of the T-Splitter. (c) Attach Beverage Line or Beverage Line to the other end of the T-splitter.
5. The keg coupler attaches to the top of a keg. Slide the coupler into the keg’s Coupler Receiver. Twist to lock the
coupler to the keg. This keg can now be dispensed as either a hot or cold beverage.

Setting Pressure
If dispensing coffee, the pressure should be set to about 30-40 PSI. The best way to set the pressure is to turn the dial on
the front of the regulator counterclockwise until it is all the way out. This will turn the regulator off. Turn the valve on the
bottom of the regulator to the side to ensure no Nitrogen will pass through the regulator. Pull the pin on the side of the
coupler to release built up pressure from the keg. Open the cold draft faucet. Nothing should come out initially as there is
no pressure to the keg. Put a container under the faucet and open the valve at the bottom of the regulator. Turn the dial
clockwise with the faucet open and beverage will start to pour. Stop turning when you get the best flow rate. This should
be about 30-40 PSI. This method should prevent your regulator from creeping.
If you are dispensing at altitude, you will need to increase your output pressure by one pound for every 2,000 feet of
elevation above sea level.
Setting Kegerator Temperature
Refer to your kegerator’s manual to change your kegerator temperature. We recommend coffee to be kept at 37 degrees.
Do not store coffee above 40 degrees.
The air temperature inside the kegerator can fluctuate greatly as you open and close the door. Check the liquid
temperature by putting a thermometer in a glass of water inside the kegerator. Let the glass cool for 24 hours with the
door shut for the most accurate reading.
