@T2 C3 COPY = Blank-off pump at intake, then inspect pump ultimate
pressure to determine if oil needs changing.<$IT2 C3 Head Tag><$IT2

@T2 C1 COPY =

@T2 C2 COPY = Clogged oxide gettering trap or filter.

@T2 C3 COPY = Open gettering trap and clean filter, then remove all
traces of ioxide powder from interior of cannister.

@T2 C1 COPY =

@T2 C2 COPY = Out-Gassing

@T2 C3 COPY = Unusual vapors or materials not normally found wihin
interia of chamber may be affecting pump performance. These could
cause the Pirani gauge to register the incorrect pressure even though
no vacuum leaks exist. Increase the pump down time if necessary to
compensate for the error.

@T2 C1 COPY =

@T2 C2 COPY = Virtual Leak

@T2 C3 COPY = Argon gas may be seaping into the interior of the growth
chamber through faulty valve seal. Alternately, solvents or air entrapments
may be effecting the results of the <169>Leak Back Test<170>.

@T2 C1 COPY = Water Flow Lamp remains on when coolant supply is turned
off.

@T2 C2 COPY = Circuit needs calibration

@T2 C3 COPY = Perform the procedure in Chapter 8, <169>Flow Switch
Adjustment<170> to check the circuit for proper operation.

@T2 C1 COPY = Water Flow Lamp remains off when coolant supply is turned
on.

@T2 C2 COPY = Faulty V1 valve or flow switch paddle

@T2 C3 COPY = Perform the procedures in Chapter 8, <169>Flow Switch
Adjustment<170> to check the circuit for proper operation.
