III. j - REMOTE CONDENSING UNIT REQUIREMENTS:
This section applies only to models RBC200/200RT and
RBC400/400RT. A remote condensing unit, operating on
R-404A refrigerant, is required for Blast Chill operation
on these models. The remote condensing unit should
be capable of providing 18,700 BTU/hr @ -10°F evapora-
tor temperature in a 90°F ambient environment.
4 HP air-cooled and 3 HP water-cooled remote condens-
ing units are available from Traulsen as an optional ac-
cessory. Increased capacity of the remote condensing
unit and line sizing will depend on the length and layout
of the connecting piping from the remote condensing
unit to the Blast Chill unit. Proper line sizing should be
defined by a qualified refrigeration engineer or techni-
cian.
III. k - REMOTE UNIT CUT-OUT SETTINGS:
This section applies only to models RBC200/200RT and
RBC400/400RTRT. The low pressure cut-out of the re-
mote condensing unit should be adjusted to obtain an
evaporator coil temperature NO LOWER THAN -15°F. If
the length of the connecting piping is 40 feet or less, the
condensing unit low pressure cut-out settings will be
approximately 15 +/- 2 PSIG cut-out and 25+/- 3 PSIG
cut-in.
III. l - SEALING ROLL-IN/ROLL-THRU UNITS:
This section applies only to models RBC200/200RT and
RBC400/400RTRT Roll-In and Roll-Thru cabinets set
on the floor require the floor area to be flat and level. In
addition, after the cabinet is set in place, sealant should
be used around the perimeter of the base to comply with
NSF International requirements. After sealing the unit,
the enclosed ramp should then be installed.
III. m - ON/OFF SWITCH:
The Traulsen Blast Chiller models are all equipped with
a power ON/OFF switch intended to cut power to the
control as needed. In the event of routine maintenance
and/or service is needed, be certain to disconnect the
electrical power to the machine and follow lockout/tagout
Procedures.
This is located on top of models RBC100, RBC200,
RBC200RT, RBC400 and RBC400RT behind the louver
panel assembly. On model RBC50, this switch is located
on the right side of the control tower.

III. i - CONDENSATE REMOVAL:
All Traulsen Blast Chill models (except model RBC50)
require the use of a floor drain or floor mounted electric
condensate evaporator.
Model RBC100 requires either a floor drain or the use of
an optional bottom mounted electric condensate evapo-
rative pan kit (BCACC-BMCE) for condensate removal.
The standard drain port location is at the rear of the unit
(see figure 7).
Models RBC200 and RBC200RT require either a floor
drain or the use of an optional floor mounted electric
condensate evaporative pan kit (BCACC-FMCE) for con-
densate removal. Two drain ports are provided, located
at the right side and rear of the unit. Plug the unused
drain port with the male pipe thread plug supplied (see
figure 8).
NOTE: Local code should be consulted when plumbing
to drain port.
