DESCRIPTION
2.1 INTRODUCTION
This guide has been prepared for the operator of Carrier Transicold refrigeration units to help deliver the load in the
best possible condition. It contains Operating Data, Electrical Data and Service Instructions for the Carrier Transi-
cold Model Neos™ 100S truck refrigeration units listed in
Table 2–1 .
Additional support manuals are listed in Table 2–2 .
Beware of unannounced starting of the unit. The unit may cycle the fans and compressor unexpectedly as control
requirements dictate. Press the OFF key on the Cab Command.
Your refrigeration unit has been engineered to provide long, trouble-free performance when it is properly operated
and maintained. The checks outlined in this guide will help to minimize on the road problems. In addition, a com-
prehensive maintenance program will help to ensure that the unit continues to operate reliably. Such a mainte-
nance program will also help to control operating costs, increase the unit's working life, and improve performance.
2.1.1 Nameplate
Each unit is identified by a nameplate attached to the frame of the unit. The nameplate identifies the complete
model number of the unit, the serial number and some other information.
If a problem occurs, please refer to the information on this plate, and make a note of the model and serial number
before calling for assistance. This information will be needed when you contact a technician so that he may prop-
erly assist you.

2.3 CONDENSING SECTION
The condensing section (see Figure 2.1 ) contains the condenser fan & coil, filter-drier, hot gas solenoid valve,
receiver, and a condenser pressure control valve.
2.3.1 Condenser Coil
The condenser is of the tube and fin type and acts as a heat exchanger in which the compressed refrigerant gas is
condensed into a liquid and lowered in temperature. Air movement over the condenser is provided by a fan
mounted in the condensing section.
2.3.2 Filter Drier
The drier is a cylindrical shell containing a drying agent and screen. It is installed in the liquid line and functions to
keep the system clean and remove moisture from the refrigerant.
