1.1 INTRODUCTION

The Carrier Transicold model 69NT40--541--200/299
series units are of lightweight aluminum frame
construction, designed to fit in the front of a container
and serve as the container's front wall.
They are one piece, self-contained, all electric units
which includes cooling and heating systems to provide
precise temperature control.
The units are suppled with a complete charge of
refrigerant R-134a and compressor lubricating oil and
are ready for operation upon installation. Forklift
pockets are provided for unit installation and removal.
The base unit operates on nominal 380/460 volt, 3
phase, 50/60 hertz power. An optional autotransformer
may be fitted to allow operation on nominal 190/230 , 3
phase, 50/60 hertz power. Power for the control system
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
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 a mechanical or 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.
1.2 CONFIGURATION IDENTIFICATION
