1. Introduction
NOTICE
This manual covers the 250ION and 240EPS ComfortPro
system. The truck must be equipped with a minimum 240
Amp alternator.
This guide has been prepared for the operator of Carrier Transicold
ComfortPro Electric Auxiliary Power Units (APU). It contains basic
instructions for the operation of the APU, safety information, and,
troubleshooting tips. Please take the time to read the information contained
in this booklet and refer to it whenever you have a question about the
operation of the Carrier Transicold Comfort Pro Electric APU.
Your Comfort Pro Electric APU 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 over-the-road problems. In
addition, a comprehensive maintenance program will help to ensure that the
unit continues to operate reliably. Such a maintenance program will also help
to control operating costs, increase the APU’s working life, and improve
performance.
This guide is intended to be an introduction to your APU and to provide
general assistance when needed. More comprehensive information can be
found in the Comfort Pro Electric APU Operation and Service manual (62-
12063), which is available from your local Carrier Transicold dealer. When
having your unit serviced, be sure to specify genuine Carrier Transicold
replacement parts for the highest quality and best reliability.
At Carrier Transicold, we are continually working to improve the products that
we build for our customers. As a result, unit specifications may change
without notice.

3. Unit Identification
Each unit is identified by a decal attached to the power unit frame inside the
upper access cover. This decal is on the horizontal part of the frame between
the lower access cover and compressor base. An additional decal is located
on the top cover of the Climate Control Unit (CCU). The decal identifies the
model and serial number of the unit, type of refrigerant, and refrigerant
charge.
If a concern arises, refer to the information on this decal, and make a note of
the model and serial numbers before calling for assistance. This is required
when you contact an authorized Carrier Transicold dealer so that they may
properly assist you.
