4.1.4.16 Af ter the turbine has been thoroughly warmed up and the temperature of the lubricating oil has reached at least 90 F, gradually OPE" the steam control valves and slowly increase the turbine rpeed until turbine speed is being controlled by the speed governor (approximately % 3000 RPM).
Go to cabinet F-161, in Relay Room, bottom-center, to the two small blue boxes (for Pi-P-l A C-1, for FW-P-1B C-2) and place the auto n.anual (lef t ha id side) switches in the auto position fully up.

Revision 5 APR 2 3 1979 09/22/78 The two feedwater pumps take a suction on a cccc:en suction header, to which condensate is supplied by the condensate / condensate booster pumps and heater drain pumps, and discharge feedwater through the 3rd stage heaters to the feedwater regulating valves and the OTSG's.
Turbine speed and the feedwater regulating valves are controlled by ICS. Check oil temperatures and levels, vibration, exposed linkage, oil filter and ccolers at least daily.
Check stop valve exerciser circuits periodically.
