Mounted both gate valves and support. Gate 
valves could not be installed one bolt 
rotated from 90 degrees as per drawings 
due to mechanical conflict with back foot.

Using rotating flanges some small rotation 
from 90 was achieved. This may be 
sufficient given the reason for the 
rotation was to avoid mechanical conflicts 
with ring parts that are no longer there.

Valve struts had to be modified as gate 
valve is much lower and close to Al frame 
than in Daresbury.

ML suggested that the reason for the 
change in height mentioned in previous 
entry is that the ring gate valve to YR10 
is not centered. Solutions will be 
considered when the other two setups in 
YR09 are mounted and the alignment 
situation is more clear

Noted a few blind flanges are bluish, 
which indicates SS 304 instead of 316. Did 
we get the wrong ones from ITL? Did we 
swap them in Daresbury by mistake? Is it 
just an odd colour?

Installed turbo pump on top gate valve, 
Pirani gauge provided by ABD (where is 
ours?) and pumped down.

Reached 10-1 mbar in 10 minutes. Turbo on.
Reached 10-5 mbar on IE514 in 17 more 
minutes (where is its manual?)

Will leave pumping overnight.
