Field Furnished Condensing Units
Howe is not responsible for the performance of
field furnished condensing units. Howe
recommends field furnished condensing units
be sized with sufficient refrigeration capacity at
the local design outdoor ambient temperature
including enough system capacity to offset
suction line pressure losses. Howe also
recommends field furnished condensing units
be at least equipped with the accessories
outlined in the previous section to ensure
successful operation of the Ice Flaker.
