d) Place the N
2
tank and N
2
regulator valve component into the
cabinet and fix the N
2
tank
with tank bracket and bolt (See
Figure 8).
4. Install the coffee keg:
Place the coffee keg into the cabinet
and firmly connect the keg’s opening to
the connection port of the mixed ball
valve (See Figure 10).
Note: To place a keg into the cabinet,
use the keg handle to move the keg
to the front of the open coffee
dispenser, then carefully tip the keg
so that the raised bottom edge contacts the edge of the cabinet. Finally, lift
the keg handle to raise the keg to the level of the floor of the cabinet and
push the keg into place.
5. Install tap handle and coffee tap:
Screw the tap handle clockwise into the coffee tap to make a firm connection.
Then connect the tap to the coffee tower components and tighten with a
wrench (See Figure 9).
6. Install upper cover guardrail and drip tray:
Set the upper cover guardrail and drip tray on top of the coffee dispenser (See
Figure 10).
Notes:
When replacing the coffee keg, first turn off the safety switch on the N
2
regulator valve and remove the mixed ball valve to take out the keg.
When replacing the N
2
gas cylinder, remember to turn off the main switch
of the N
2
gas cylinder and the safety switch on the N
2
regulator valve.
Afterwards, use a wrench to loosen the hexagonal nut port connecting the
N
2
regulator valve with the N
2
tank. Then, using a wrench, remove the
fixed bolt of the N
2
tank to take out the N
2
tank.
During the installation process, be sure that all parts are connected tightly
and that there are no gas leaks.
When connecting the hose to the connection port, you can dip the ends
into warm water to make the connection easier.
If the high-pressure compressed gas in the N
2
tank is not handled
properly, it could be dangerous:
a. Make a note of the D.O.T. testing date on the cylinder neck before
installation. If it is more than 5 years old, don’t use the product. Return
it to the gas supplier.
b. Keep gas cylinder away from heat sources. Unused cylinders should
be placed upright in a cool, ventilated place (preferably at 70F).
