Manifold Gauge Set Connection

Service Hose Adapter Tools:

1 Turn both manifold gauge set valves all the way to the right, to close the high and low pressure hoses to the center manifold and hose. A Rotunda Adapter D81L-197O3-A or Motorcraft Tool YT-354 or 355, or equivalent must be used to connect the manifold gauge set or charging station to the high pressure service gauge port valve.
2. Remove the caps from the high and low pressure service (Schrader) gauge port valves.
3. If the manifold gauge set or charging station hoses do not have valve depressing pins in them, install Fitting Adapters T7IP-19703-S and R or equivalent (which have pins) on the low and high-pressure hoses.

Refrigerant System Connections:

4. Connect the high and low-pressure hoses or adapters to the respective high and low-pressure service gauge port valves. The adapter must be used on the high-pressure gauge port valve.
