6. Lower the side box to provide wrench clearance to

the injection valve bolt.

7. Install a new valve, using new gaskets and torque

to 25 - 30 ft-lb. Note: In an emergency, gaskets

may be re-used if there is no apparent damage to

the gasket such as tearing or delamination.

IMPORTANT! Note that there are two gaskets used.

8. Remount the side box by installing screws “A” and

“B.”

9. Install the injection coil and terminal box harness

connections (push them in until a distinct “snap” is

heard). The connectors are designed to guaran-

tee proper orientation. If they won’t go in, rotate

them 180º and try again.

10. Reconnect the liquid line to the new valve. Note

that trimming the injection valve tube may damage

the internal strainer. Emerson Climate

Technologies, Inc. recommends that modifications

not be made to the tube. Use the same flame pre-

cautions as in step 2.

11. Use approved refrigeration service procedures to

evacuate the compressor and liquid line. Make

certain that liquid is available to the injection valve

by opening the supply valve.
