Swagelok (VCR) fitting instructions
CAUTION
VCR fittings are very susceptible to damage to the sealing surfaces therefore extreme caution
must be taken not to damage the sealing surfaces.
Always use the correct washers supplied in your tool kit. It is not possible to redress the
surfaces as described for Parker fittings.
Verify the isolation valves inside access door on front of TVP unit (under the panel) are closed
(see diagrams 14a and 14b).
Remove the blank-off fittings from the coupling lines on the unit. Some refrigerant gas may
escape. If this continues the valves are not properly closed or have failed. If valves have
failed replace the blank-off fittings immediately and contact your vendor.
Attach the refrigerant line to the TVP unit in the same manner as described above. Over
tightening Cajon VCR fittings will cause distortion of the washer and leaks.
Provide support for the refrigerant line. This should occur at mid point on a 2 m line. Ensure
that the support is in contact with the insulation only and not in contact with any exposed
tubing or couplings.
