3.2 COOLING
Serving beer tanks are available as single-wall units without insulation or insulated double-wall units.
Double-wall serving beer tanks have cooling spirals or cooling plates. Double-wall serving beer tanks
require minimal modifications to surroundings, but should be located in an area protected from frost and
full sunlight. See Figure 3 for cooling connections.
Single-wall serving beer tanks are usually kept in cool cells that cool the entire system. While single-wall
serving beer tanks may require additional space, their lighter weight allows for easier installation.

3.3 INLINER
An inliner (see Figure 4), also called a beer liner, is a food-grade, low pressure, polyethylene bag that is filled
with beer. The bag can be removed when empty, making the cleaning of the tank virtually unnecessary.
Special discharge openings called piercing valves are used in conjunction with inliners (see Section 3.4).
Contact your Paul Mueller Company sales representative to purchase inliners. See Section 6 for details.
FIGURE 4: INLINER INSIDE SERVING BEER TANK
3.4 PIERCING VALVE
A piercing valve is installed on the serving beer tank when inliners are used and serves as a pressure- and
fluid-tight seal between the serving beer tank and beer discharge openings. With the piercing valve, the
inliner can simply be pushed into the appropriate fitting and will be sealed hermetically for beer and air.

4.1 SECURING SERVING BEER TANKS FOR TRANSPORT
CAUTION: When transporting serving beer tanks by truck, ensure the tanks are completely
secured using the pallets provided by Paul Mueller Company to prevent shifting or falling. Pay
special attention to vulnerable protruding parts and manometers.
IMPORTANT: Always inspect the serving beer tank for damage before transport. Do not proceed
with assembly of a damaged serving beer tank, but return to Paul Mueller Company for inspection.

4.3 INSTALLATION PRECAUTIONS
CAUTION: Because hoisting the serving beer tank is necessary during installation, please observe
all required safety precautions.
IMPORTANT: During hoisting, make sure no foreign (i.e., not rust proof) metals come in contact
with the serving beer tank as this could lead to undesired corrosion. Wood or plastic support
material is recommended, as well as the use of clean slings.
Before placing the serving beer tanks, inspect the location’s floor to determine whether it provides
adequate support. Take point load into consideration.
In the event that the tanks will be located in an environment that poses potential risk (i.e., in a
situation where there is the likelihood of vibrations caused by heavy traffic, earthquakes, or due to
installation on a movable platform, such as a ship), consultation with your Paul Mueller Company
representative to discuss these conditions is required. Extra stability measures should be taken
before placement of the serving beer tank in these instances.
CAUTION: Various supplies are required for the beer tank: a cool water source, a compressor,
beer mains, and beer hoses take up space around the serving beer tank and can result in less space
for service and waiting. Ensure these supplies do not place an undesired reaction force on tanks,
appendages, and frames, as this can lead to installation instability.
IMPORTANT: Ensure the tank is placed in a frost-free location without exposure to direct sunlight
with a constant temperature between 0–30°C (32–86°F).
Make sure the site is properly equipped with all necessary equipment and supplies before proceeding with
installation. The services of a plumber and/or an electrician may be needed before installing the water
cooling system.
Serving beer tanks should only be lifted by a forklift while in frame. If not in frame, serving beer tanks
should be lifted by no less than two (2) people. Paul Mueller Company suggests using lashing gear to lift the
tanks when not using a forklift. It is recommended to lift the tanks from both ends, using the manway and
center end point (using a threaded bolt in the tank) to lift from center end point.
WARNING: Under no circumstances should the tanks be lifted while pressurized.

4.4 ADJACENT INSTALLATION OF SERVING BEER TANKS
When the serving beer tanks are installed in an adjacent position, Paul Mueller Company recommends
using the standard frames provided.
IMPORTANT: All threaded connections must be checked carefully with a spanner wrench.
4.5 STACKED PLACEMENT OF SERVING BEER TANKS
To stack two serving beer tanks in frames, two complete and independent frames must first be assembled
and the lower tank installed first. Approximately two inches must be left free between the conveyor band
and the piercing valve. Connect the tubes and place the second frame on the first frame. At this point, the
second serving beer tank can be installed (see Figure 9). The second tank must protrude far enough out in
front of the first tank so that the piercing valve can be introduced. Serving beer tanks can also be stacked
directly above each other if an optional raising set is used.
IMPORTANT: All threaded connections must be checked carefully with a spanner wrench.
FIGURE 9: STACKED PLACEMENT OF SERVING BEER TANKS
4.6 FRAME ADJUSTMENT
Adjustments will be necessary after assembly of the serving beer tank frames. Place the frame at the first
level, and then place the frames in a longitudinal direction on a slat with a 1–1.5% angle (1–1.5 cm p/m),
which is the lowest point that still allows flow.

4.7 PRESSURE SAFETY VALVE INSTALLATION
The pressure safety valve is attached to the serving beer tank with a G 3⁄4" threaded connection. A Teflon™
gasket should be placed between the fitting and the serving beer tank to ensure pressure tightness. Secure
the connection with two wrenches so that only the rear wrench is in a fixed position to prevent excess
pressure (see Figure 10).
FIGURE 10: SECURING THE PRESSURE SAFETY VALVE
4.8 CONNECTING THE WATER/GLYCOL COOLING SYSTEM
The serving beer tank’s water cooling system consists of an entry and exit opening with a G 3⁄4" or G 5⁄8"
threaded tube. The threaded tube connection is a solid soldered joint with a copper cooling spiral.
IMPORTANT: To prevent stripping or other damage to the cooling spiral during removal, secure
the threaded tube attached to the tank with a wrench to prevent its rotation when installing the
water cooling connection (see Figure 11). Instead of turning the back nut key, you must prevent it
from turning along with the front nut key.

4.10 INLINER INSTALLATION
IMPORTANT: Inliners are designed for single use only!
1. Wash hands or wear gloves during this procedure.
2. Replace the sealing ring under the transit bush, if necessary, by removing the DN32 coupling nut at the
bottom of the tank and pushing the transit bush up inside. Be careful not to lose the transit bush’s pin.
2. Clean the connection ferrule inside the serving beer tank as described in Section 4.12.
3. Remove the inliner from the plastic bubble wrap, ensuring it does not come into contact with anything.
4. With the plastic connection of the inliner facing the connection ferrule inside the serving beer tank,
push the inliner down until the connection stays in place and is fully inserted in the connection ferrule
(see Figure 13).
5. Ensure the inliner is straight. Unroll the inliner 8 to 10 inches toward the back of the serving beer tank.
IMPORTANT: The inliner was packaged and shipped in such a way that after installation in the
beer tank, it can roll out to the back and then unfold to the side when it is filled (see Figure 4).
FIGURE 13: CONNECTING THE INLINER
7. Attach the piercing valve (see Figure 14A). Tighten the coupling nut with a spanner wrench (see
Figure 14B).
