T.X.V. INSTALLATION
To replace the T.X.V., perform the following proce-
dures:
CAUTION
WHEN PLACING THE T.X.V., A HEATSINK (WET
CLOTH) MUST BE USED TO PREVENT
DAMAGE TO THE VALVE.
1. Position the T.X.V. with heatsink so the liquid line and
suction line correspond with the proper valve ports.
2. Braze the liquid line and suction line to the T.X.V. by
using the appropriate brazing material.
3. Remove the heatsink from the T.X.V.
4. Replace any foam insulation to the surrounding lines.
5. Replace any insulation to the T.X.V. and surrounding
areas.
NOTE
The liquid line from the condenser is bonded to
the suction line to provide a heat exchange to help
protect the compressor from liquid slugging. This
also assures that sub-cooled liquid is being
supplied to the expansion devices.
