The replacement sampling unit is supplied without injection valve and analytical head
assembly. If you are exchanging the complete sampling unit, remove the injection valve and
the analytical head from the defective sampling unit. Install the valve and analytical head in
the new sampling unit. See
“Injection-Valve Assembly" on page 139 and “Metering-Drive
Motor and Belt" on page 141
