2. Isolate the compressor and recover the refrigerant according to industry standards. Refer to
"3.1 Refrigerant Containment" on page 41.
3. Source appropriate OEM specified and procured flexible line.
4. Remove the nut from the connection fitting body. Discard the blanking disc, nut, and braze
sleeve.
5. Before installation of the OEM supplied flexible line, inspect the O-ring face to ensure it is clean
and free from scratches or other damage. Lightly smear O-ring lube on the O-ring face of the
line and install using two (2) wrenches; one to hold body of fitting and one to tighten the nut.
This is done to prevent over torqueing the fitting in the compressor housing.
6.
Flexible lines are not supplied by Danfoss LLC. Selection of appropriate hose and fitting is the responsibility of OEM/installer. This
information is readily available from various sources.
Rigid 1/2 inch copper connection
1. If the connection is 1/2 inch rigid copper, a length of 1/2 inch copper must be brazed into the
braze sleeve.
2. Isolate the compressor and recover the refrigerant according to industry standards. Refer to
"3.1 Refrigerant Containment" on page 41.
3. Remove the nut from the connection-fitting body. Discard the blanking disc. Locate the braze
sleeve and clean. Ensure removal of all oil and surface debris. Braze as per the OEM standard
process for copper/steel joint.
4. Place an appropriate length of 1/2 inch copper tube into the braze sleeve. Pretreat/flux joint
area as per the OEM standard procedure. Braze the pipe to the sleeve ensuring the nut can be
fitted after brazing or otherwise position as required. Clean flux and any excess filler from joint.
5. Clean the O-ring face of the sleeve ensuring no scratches or debris are present. Apply a light
amount of O-ring lube to the face of the sleeve and assemble to the fitting. Tighten the nut
using two (2) wrenches; one to hold body of fitting and one to tighten the nut. This is done to
prevent over torqueing the fitting in the compressor housing
Rigid 3/8 inch copper connection - TTS300/TGS230
• If the connection is 3/8 inch rigid copper, a length of 1/2 inch copper must be brazed into the
braze sleeve as described above. A transition fitting should be brazed to connect the 3/8 to 1/2
inch tubes. Follow the procedure as noted above in Rigid 1/2 Copper Connection section.
Important
• It should be noted that the inclusion of a strainer within the connection body is intended as a
last resort backup only to prevent ingress of debris that may block solenoid orifices or restrict
motor and power electronics cooling. It is not a substitute for a correctly sized full-flow filter
drier. A filter drier must be installed in all instances. If it is found that a filter drier is not installed,
and the fitting is changed due to a field replacement of the compressor, a filter drier must be
included in the line modification.
• If it is required to remove the fitting from the housing for any reason, clean the O-ring, fitting
and housing threads, and apply a small amount of O-ring lube before reassembly.
