How to Use CS27K6E-TF5-945 – Upgraded Replacement 230V 3 Phase 26,800 BTU R404A Compressor Compatible with Copeland: Complete Guide

Proper installation and handling are critical to the performance and longevity of any compressor. This guide assumes you are a qualified HVAC technician.

Step 1: System Preparation and Safety

Before touching the new unit, recover all refrigerant from the existing system following EPA guidelines. Disconnect all electrical power and verify it is dead with a multimeter. Carefully remove the failed compressor, noting the routing of wires and refrigerant lines. This is the time to also replace the filter-drier and check the system for acid or contamination. A clean system is vital for the new CS27K6E compressor replacement.

Step 2: Compressor Preparation and Installation

Once the old compressor is out, prepare the new CS27K6E. Check the oil type and charge; it may come with a charge of POE oil compatible with R404A, but always verify. Position the new compressor on its mounting pads, ensuring it is level. Connect the suction and discharge lines, using new gaskets or O-rings. Torque connections to manufacturer specifications to avoid leaks. This direct-fit design makes the physical installation straightforward if you are familiar with Copeland systems.

Step 3: Electrical Connection and Initial Setup

Connect the three-phase power leads (L1, L2, L3) to the appropriate terminals on the compressor’s contactor or directly as per your system’s wiring diagram. Ensure all connections are tight and that the correct overload protection is in place. Do not apply power yet. This step confirms why it’s considered a best compressor for Copeland system—the electrical terminals are in the expected locations.

Step 4: System Evacuation and Charging

With all connections made, the system must be evacuated to a deep vacuum (below 500 microns) to remove moisture and non-condensables. This process can take several hours for a thorough job. Once the vacuum holds, break the vacuum with refrigerant vapor before opening the liquid line valve. Charge the system with the specified amount of R404A refrigerant, using subcooling or superheat methods as appropriate for your system type.

Step 5: Initial Start-Up and Monitoring

Now, apply power. Start the system and immediately monitor amp draw on all three legs. It should be balanced and within the rated load amps (RLA) on the compressor nameplate. Listen for any unusual noises. Check suction and discharge pressures, ensuring they are within normal operating ranges for the ambient conditions. Monitor system operation for at least 30 minutes, checking for stable performance. For more on system commissioning, see our HVAC startup checklist.
