INTRODUCTION
2.1 Introduction
The Carrier Transicold PrimeLINE models 69NT40-561-200 to 299 and 69NT40-561-500 to 599 are units of
lightweight aluminum frame construction, designed to be bolted on to the front of a container and serve as the
container’s front wall. Forklift pockets are provided for unit installation and removal.
The Carrier Transicold PrimeLINE ONE™ models 69NT40-565-200 to 299 and 69NT40-565-500 to 599 are units
of lightweight aluminum frame construction, designed to be directly installed on-site onto a welded front wall of a
container.
PrimeLINE units are self-contained, all electric units, which include cooling and heating systems to provide precise
temperature control. The units are supplied with a complete charge of refrigerant and compressor lubricating oil,
and are ready for operation upon installation.
The base unit operates on nominal 380/460 volt, 3-phase, 50/60 hertz (Hz) power. An optional autotransformer
may be fitted to allow operation on nominal 190/230, 3-phase, 50/60 Hz power. Control system power is provided
by a transformer which steps the supply power down to 18 and 24 volts, single phase.
The controller is a Carrier Transicold Micro-Link 3 microprocessor. The controller operates automatically to select
cooling, holding or heating as required to maintain the desired set point temperature within very close limits. The
unit may also be equipped with an electronic temperature recorder. The controller has a keypad and display for
viewing or changing operating parameters. The display is also equipped with lights to indicate various modes of
operation.
2.2 Refrigerant
PrimeLINE models 69NT40-561-200 to 299 and PrimeLINE ONE™ models 69NT40-565-200 to 299 are units
designed to only be charged with R-134a refrigerant.
PrimeLINE models 69NT40-561-500 to 599 and PrimeLINE ONE™ models 69NT40-565-500 to 599 are R-513A-
ready units. They are supplied with a complete charge of R-134a refrigerant. But, they are capable of being field
converted to R-513A refrigerant at a later date as requested by the unit owner. R-513A is an azeotrope blend
containing R-1234yf and R-134a. All information in this manual pertaining to R-513A is only applicable to 561-500
to 599 or 565-500 to 599 model units that have either been converted or are being converted to R-513A.
To convert a R-513A-ready unit to R-513A refrigerant, refer to the procedure in
of the Service chapter.
2.3 Configuration Identification
Unit identification information is provided on a unit nameplate (see
) located on the back wall of the
condenser section. The nameplate provides the unit model number, serial number and parts identification number
(PID). The model number identifies the overall unit configuration, while the PID number provides information on
specific optional equipment, factory provisioned to allow for field installation of optional equipment and differences
in detailed parts.
2.4 Feature Descriptions
2.4.1
Control Box
Units are equipped with an aluminum control box, and may be fitted with a lockable door.
2.4.2
Temperature Readout
The unit is fitted with suction and discharge refrigerant temperature sensors. The sensor readings may be viewed
on the controller display.
2.4.3
Pressure Readout
The unit is fitted with an evaporator, suction, and discharge pressure transducers. The transducer readings may be
viewed on the controller display.
