Utility Distribution System
CaptiveAire Systems' UDS provides
unequaled cooking line versatility, flexibility
and convenience.
One connection for all your utility needs
The CaptiveAire Utility Distribution System (UDS) is designed to meet all electrical and plumbing requirements for
your kitchen appliances. A two compartment raceway houses either an electric copper bus bar or wireway which is
completely isolated from the plumbing supply manifolds.
ADVANTAGES
Efficiency for Today - Flexibility for Tomorrow
additional capacity according to job specifications. Spare connection points are provided for future cooking
equipment expansion; therefore adding new equipment requires minimal effort. Rearranging the cooking line-up
can be accomplished in a matter of minutes, especially when equipment is on casters.
Electrical Riser: Main power connection is made to the main circuit breaker which has a shunt trip and is mounted
in the electrical riser.
Bus bar systems: Electrical power is fed through the main circuit breaker to the bus bar system in the raceway.
Each appliance is fed from the bus bar through individually sized circuit breakers located along the raceway.
Wireway systems: Electrical power is fed through a main circuit breaker to a distribution panel which contains
individual branch breakers. Each appliance is fed from the individual breakers which are wired to each receptacle
located along the raceway.
Plumbing Riser: The plumbing riser houses manual (quarter-turn) shut-off valves for each incoming main supply
line located in the UDS. The plumbing manifolds are provided with stub-outs along the raceway for the individual
plumbing connections. Each stub-out is equipped with a manual (quarter-turn) shut-off valve.

SPECIFICATIONS
Utility Distribution System shall be the CaptiveAire model UDI (or UDW). Overall size shall be as shown on
drawings. Systems shall have two vertical risers, one on each end, with one dedicated to electrical and the other to
plumbing. The horizontal distribution raceway between the risers shall be separated into electrical and plumbing
compartments and each shall be completely enclosed and water tight with removable access panels. The risers
and raceway shall be constructed of 16 gauge, type 304 stainless steel, #4 finish. The system shall be completely
pre-wired and pre-plumbed with one (1) final connection point for all incoming services. A circuit protected dual
convenience outlet shall be provided on each riser. Service connections shall be located behind easy lift out
access panels.
ELECTRICAL
water and steam supply and return manifolds shall be insulated. All incoming service connections shall be provided
event of a fire. Electrical gas valves shall be furnished with a manual gas reset button located in the UDS riser. Gas

Bus Bar Systems: The electrical raceway shall be a four (4)
conductor copper bus bar system having balanced load and phases
and shall be completely isolated from the plumbing supply manifolds.
Point of use circuit breakers shall be mounted on connection plates
which are located on the peaked top of the raceway and protected
by a water proof stainless steel hinged cover. The breakers shall be
easily accessible to the operator. The connection plates shall be
easily interchangeable with spare blank plates which shall be
provided for future expansion or changes. A main circuit breaker with
a built-in 120 VAC rated shunt trip shall be furnished in the electrical
riser and require a single point incoming connection. Terminal block
connections shall be provided for field interconnection between the
shunt trip and the fire protection system for power shut-off in the
event of a fire.
Wireway Systems: The electrical system shall consist of a main
circuit breaker which feeds power to a distribution panel located in
the electrical riser containing individual branch breakers. Each
appliance is fed from the individual breakers which are wired to each
receptacle located along the raceway and shall be completely
isolated from the plumbing supply manifolds. The main circuit
breaker shall be equipped with a built-in 120 VAC rated shunt trip
and shall be located in the electrical riser requiring a single point
incoming connection. Terminal block connections shall be provided
for field interconnection between the shunt trip and the fire protection
system for power shut-off in the event of a fire. All outlets shall be
equipped with grounding type receptacles having specific NEMA
polarized configurations and located on the under side (Model UDI)
or front side (Model UDW) of the raceway at each equipment location. Outlets are matched to the cord and
plug sets supplied with equipment. On the Model UDI, twist lock cord and plug sets are provided for
equipment supplied without cords. On the Model UDW, straight blade cord and plug sets are provided for
equipment supplied without cords.
