applications. Customer is required to hook up termi-
nal plate for applicable voltage. Wiring hook up dia-
grams are included in the compressor terminal box.
Also a typical 230-v wiring schematic is included with
this guide on page 27.

All Carlyle Compound Cooling compressors (16 to
37 cfm) are provided with complete motor overcur-
rent and overtemperature protection, which complies
with UL and NEC requirements for inherent motor
protection. Primary motor protection is provided by
current sensitive relays located inside the compres-
sor terminal box. Thermal protection is provided by
an internal thermostat embedded in the motor wind-
ings. All Carlyle Compound Cooling compressor (16
to 37 cfm) models are UL and CSA approved with
R-22, R-404A, and R-507 refrigerants.
8.
The 50 to 99 cfm Carlyle Compound Cooling com-
pressor models are provided WITHOUT motor over-
current protection, which MUST be supplied by the
customer. Calibrated circuit breakers and Furnas
solid-state overload relays specifically selected for
each motor and voltage are available and recom-
mended.
9.
See circuit breaker accessory selection. If OEM cus-
tomer selects alternate overcurrent protection, it
must be approved by Carlyle Application Engineering
Department. The use of authorized overcurrent pro-
tection is part of the basis of UL recognition. Selec-
tion of alternate overcurrent protection without
Carlyle’s approval will VOID warranty.
10. All nine Carlyle Compound Cooling compressor mod-
els have a well in the cast iron bottom plate in which
a crankcase heater can be inserted. A crankcase
heater is recommended for use with all Carlyle Com-
pound Cooling compressor
models. All 180 watt
insertion type crankcase heaters are required to use
thermal grease provided in the accessory package
(grease part number 38AQ680001).
11. All Carlyle Compound Cooling compressor models
are provided with a temperature sensor installed in
the high stage cylinder head to monitor the tempera-
ture of the discharge gas. If the discharge gas tem-
perature in the head exceeds the trip setting of 295 F
(146.1 C), the sensor will open the control circuit and
shut off the compressor.
12. All Carlyle Compound Cooling compressor models
are now being shipped without oil.
