Service Fittings:
There are two basic styles of service fittings: Front load and remote control. A front
load fitting’s valve is located immediately behind the handle, inside the fascia. A
remote control fitting’s valve is located immediately behind the fitting, behind the
hood wall. The handle of the service fitting has a color-coded index button indicating
the service. The type of service determines the valve type and the maximum
pressure. See the chart below for information on individual fittings.
