1.2 Purpose
This Service Manual is intended to provide service procedures specific to the Danfoss Turbocor compressors. It is not
intended to teach basic fundamental safety, refrigeration, electrical, or fitting skills. It is assumed persons using this
manual will be appropriately certified and have detailed knowledge, experience, and skills in respect to working
with high-pressure refrigerants and medium voltage electrical components to 1 Kilovolt (kV) high-power alternating
current (AC) and direct current (DC).
Some potential safety situations may not be foreseen or covered in this manual. Danfoss LLC expects personnel
using this manual and working on Danfoss Turbocor compressors to be familiar with, and carry out, all safe work
practices necessary to ensure safety for personnel and equipment.
The purpose of this manual is to provide:
l
A general description of the compressor design
l
A functional description of the various components of the compressor
l
Information regarding procedures necessary to detect the source of a problem within the
compressor
l
The procedures for disassembling and assembling various components of the compressor
l
Fault and calibration interpretations
l
System troubleshooting suggestions
NOTE
Bearing and bearing sensor repairs are not covered in this manual as they are not field serviceable. Compressors requiring such repairs
must be sent back to the factory for inspection and repair.
This manual gives only general procedures for servicing and does not provide part numbers of single products or
single components. If this information is required, please contact a recognized Danfoss Turbocor original equipment
manufacturer (OEM) customer.
Additionally, this manual is written for Major revision F and later compressors. When necessary, particular revision
compressors are specified, but the majority of the content remains the same, regardless of the compressor revision.
Danfoss LLC does sell various upgrade kits (e.g., Soft Start Upgrade Kit) and those kits may include retrofit cabling or
other hardware that are not specifically installed on production compressors. This manual only illustrates
components that were installed on production compressors. Always refer to the specific spare part kit instructions
during installation.
1.3 Organization
This manual is organized in the following manner:
l
Section 1: Introduction
– this section describes the purpose of the manual, its organization,
conventions used in the manual, and a safety summary which describes the use of Danger, Caution,
and Notes symbols
l
Section 2: Compressor Fundamentals
– this section identifies the parts of the compressor and
provides fundamental knowledge of the role each component plays in the main fluid path, motor-
cooling system, and in the energy and signal flow
l
Section 3: Compressor Removal and Installation
– this section describes the safe practices of
removing and installing the compressor
l
Section 4: Compressor Components
– this section describes in depth component information,
the steps necessary to obtain measurements that verify a component is functional and the steps
necessary to replace a compressor component
