Model BCC/BCR-140, BCC/BCR-175, BFR/BCR-350
Take into account the pressure drops when determing the length
of the refrigeration line between the condensing unit and the blast
chiller/freezer. The refrigeration specifications given by the
manuafacturer for the blast chiller/freezers work properly with a
maximum length of 50 feet (15 m) and 13 feet (4 m) high
between the condensing unit and blast chiller/freezer. Beyond
this distance, a more powerful condensing unit will be needed.
To ensure proper operation, check for leaks on the
refrigeration system before leaving the installation.
Check the settings and correct operation of the saftey
devices on the condensing unit.
Installing Condensing Unit Outdoors
• Use a unit with bodywork designed for exterior installations, or
place the unit where it is protected from the elements (rain, sun,
etc.)
• Place the unit so the air flow is not against the prevailing winds
• Observe the minimum distances between the unit and nearby
walls, especially where the condenser is located and for
technical access
Installing Condensing Unit Indoors
• Preferably the remote condenser should be outdoors, or water-
cooled, connected to a chilling tower
• For air condensation units, make sure the ventilation can
dissipate the heat well enough to operate within the range of
temperatures given by the manufacture
• No electrical connection is required between the condensing unit
and the blast chiller/freezer; the unit should operate in “pump-
down” mode, being stopped and started by the low pressure,
pressure controller
• Install “traps” on the rising aspiration lines and provide slopes in
the line, so the oil returns to the compressor
