SIMPLE CONTROL CIRCUIT - A low voltage printed circuit
board contains a low voltage terminal strip. An additional set of
pin connectors is also provided so that field interface of external
controls will be simplified. Mate-n-lock plug connectors are
used where line and low voltage wires pass thru internal
bulkheads. This allows for easier troubleshooting and
component replacement. The electrical control box is not
located in the compressor compartment so the access cover
can be removed for troubleshooting without affecting the
normal system operating pressures.
AIR FILTERS - Units come standard with 2" throwaway filters.
The unit filter racks can accommodate 1" or 2" filters without
any modifications.
SYSTEM PROTECTION - Crankcase heaters and internal
compressor protection are standard on all compressors. Each
unit has suction line freezestats, low pressure switches, high
pressure switches and high temperature switches to protect all
system components. All units have bi-directional liquid line
filter-driers--except 575 volt units which has a discharge line
filter-drier. The units will operate on cooling down to 45
°
F
without any additional low ambient controls.
