Centrifugal Disassembly and Reassembly
SER 130

Experienced service mechanics who take this class will learn how to properly disassemble Carrier’s low and high-pressure 19D, E, F, XL, XR and 19XRV centrifugal chillers.

  • Learn techniques and procedures for using precision instruments to determine clearances, fits, and tolerances of bearings, seals and components
  • Study compressor lubrication and motor cooling
  • This class is almost completely a lab course, and students work in teams to disassemble, adjust, and reassemble the various chiller models

This class is intended to be the follow-up class to SER 120, Centrifugal Chiller Fundamentals, and is designed to teach experienced service mechanics how to properly disassemble both low- and high-pressure centrifugal compressors, including Models 19D, 19E / F and 19XL, XR, and XRV. Techniques and procedures for using precision instruments are taught for determining clearances, fits, and tolerances of various bearings, seals and components. Students also review compressor lubrication and motor cooling. This class is almost completely a lab course, and students work in teams to disassemble, adjust, and reassemble the various chiller models. Because this course is lab oriented with enhanced student/instructor contact, attendance is limited and early registration is recommended.

Upon request, the EPA 508 certification can be held after class at a slight additional cost. This certification is required to handle refrigerants.

Who should attend this training

This course is for HVAC technicians with a minimum of one year of field experience or a graduate of an HVAC training program. Students are expected to have basic math skills and a basic understanding of HVAC tools (gages and digital thermometers) and troubleshooting equipment.

Learning Objectives

At the conclusion of this course each student should be able to:

  • Identify correct SOM manual for correct factory specifications and clearances
  • Use proper procedure to disassemble a Carrier centrifugal compressor
  • Demonstrate proper use of dial indicator, micrometer, and depth gage
  • Demonstrate proper measurement and adjustment of thrust bearing
  • Check and adjust impeller spacing
  • Measure bearing clearances

Training Methods Used

This course uses a combination of classroom lecture, videos, animations, tours in the training facility lab, demonstrations, practical labs on operating equipment and workshops to present the material. Student’s achievement of the learning objectives is determined by successful completion of the workshops, labs, homework, and final written and practical exam. Workshops are instructor guided exercises using the procedures taught in the lectures.

Topics Covered

All times are approximate and shown as (classroom hours/lab or workshop hours).

  • Tools used in compressor service (2.0/0.5)
  • 19D disassembly / reassembly procedure (2.0/5.0)
  • 19XL/XA disassembly / reassembly procedure (2.0/5.0)
  • 19EA/FA disassembly / reassembly procedure (2.0/11.0)

Completion requirements

To receive a certificate for this course student must be present for the entire course, complete all workshops and labs and receive a grade of 70% (C+) on graded labs, homework and final.

Prerequisite requirements

Successful completion of the SER 120 course is required. Due to the nature of this course and what is taught in SER 120 there are no exceptions.

Suggested background

For technicians just entering the HVAC field or persons with no field experience, this course is most effective when preceded by the BASIC Program (SER400), which introduces participants to fundamental concepts of both air conditioning and heating systems, including lab time with service test equipment and tools.

Materials to bring

No special equipment is required we provide the appropriate safety equipment required by Carrier. Arc flash equipment is not required for the voltages used in the lab, if you are required by your company to use other PPE you may bring that to class.

What you will receive

Students in this course receive a course workbook, Carrier Service Procedures handbook, safety gloves and goggles, charging calculators, and PT cards.

Appropriate dress for this class

This class has a number of exercises that take place in the lab on operating units; participants should wear long pants, closed toed shoes and appropriate shirt, long or short sleeve. If your employer requires special dress which is more stringent than these requirements, this dress should be worn.

Class hours

Class starts at 8 AM Monday and runs from 8 AM till 5 PM each day including Friday. Travel arrangements should be made accordingly.

Location & lodging

Carrier University is located at 6540 Old Collamer Road South, East Syracuse, NY 13057. Lodging options can be found here.
