@T2 C1 COPY = Vacuum pump does not lower pressure to ultimate system 
pressure.<$IT2 C1 Copy Tag><$ITags;T2 C1 Copy>

@T2 C2 COPY = Oil Contamination<$IT2 C2 Copy Tag><$ITags;T2 C2 Copy>

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

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

@T2 C1 COPY = 

@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 C2 COPY = Out-Gassing

@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.
