PRE-INSTALLATION PLANNING
GENERAL:
Determine and confirm the appropriate location for mount-
ing the Mustang Tower with the store manager. Typically,
this will be the same location where all other soft-drink
and beverage dispensers are located.
MUSTANG TOWER WITH DRAIN FITTING:
Ensure that the drain hose assembly is within distance of
a drain according to federal, state, and local codes and
regulations.
BIB RACK LOCATION:
Determine where the BIB rack is located, if one already
exists. If a BIB Rack does not exist, work with the
manager to determine the optimal location for the new BIB
Rack.
UNDER COUNTER (Fig.1):
Taking available space into account, locate the BIB
Pumps and Rack in cabinetry directly below the Mustang
Tower. Confirm that there is enough space available for a
rack capable of holding 8 BIB containers.
ADJACENT ROOM OR STORE ROOM (Fig.2):
In most cases under counter storage space will not be
available and the BIB Pumps and Rack storage rack must
be located remotely, such as: in the next room or in a
remote storage area, next to any existing soft-drink BIB
Rack, if one exists. Run the syrup line bundle as
appropriate according to federal, state, and local codes
and regulations.
