WHEN STEAM PRESSURE SENSING INSTRUMENTS (PRESSURE INDICATORS, PRESSURE SWITCHES, AND PRESSURE TRANSMITTERS) ARE FIELD INSTALLED THE FOLLOWING PROCEDURE IS RECOMMENDED:
1. INSTRUMENTS TO BE SUPPORTED TO MINIMIZE VIBRATION AND MECHANICAL INJURY.
2. INSTRUMENTS TO BE PROVIDED WITH A WATER SEAL, TO ASSURE THAT STEAM DOES NOT CONTACT MECHANICAL INTERNALS, LOCATED ADJACENT TO THE INSTRUMENT
3. ADEQUATE VENTILATION TO BE ASSURED SO THAT THE TEMPERATURE AROUND THE INSTRUMENT AND WATER SEAL DOES NOT EXCEED 71.1 DEG. C. (160 DEG. F.).
NOTE: FOR PREVENTION OF DAMAGE TO STEAM TURBINE, SEE ASME STANDARD NO. TDP-1-1985.
THE FOLLOWING ARE THE D-R RECOMMENDED ALARM AND TRIP SETTINGS FOR TURBINE

TOTAL 3 GPM 300 BTU/HR
GLAND SEAL OPERATING INSTRUCTIONSSTART UP
A) FILL CUSTOMER’S LOOP SEAL LINE WITH WATER.
B) OPEN ALL GAUGE VALVES.
C) ADMIT COOLING WATER TO GLAND CONDENSER TK-700.7.
D) CLOSE VALVE HV-XXX.7 LOCATED BETWEEN STEAM STRAINER FC-700.3 AND EJECTOR PE-700.6.
E) OPEN VALVE HV-XXX.7 AT BLOW-OFF CONNECTION OF STEAM STRAINER FC-700.3.
F) AFTER ALL CONDENSATE IN THE STEAM SUPPLY LINE HAS BEEN BLOWN OFF, CLOSE STEAM STRAINER BLOW-OFF
VALVE HV-XXX.7. OPEN VALVE HV-XXX.7 LOCATED BETWEEN STEAM STRAINER FC-700.3 AND EJECTOR PE-700.6.
REGULATE FLOW CONTROL VALVE HV-XXX.4 SO THAT 60 PSIG IS INDICATED ON GAUGE PI-700.5.
G) BRING TURBINE UP TO RATED LOAD AND SPEED PER START-UP PROCEDURE.
H) ADJUST VALVE HV-XXX.4 SO THAT 20" WATER VACUUM IS INDICATED BY GAUGE PI-700.8. IF IT IS NECESSARY,
INCREASE THIS VACUUM UNTIL ALL LEAKAGE PAST THE OUTER PACKING RINGS IS ELEMINATED. IF CYCLING OF
PRESSURE IS INDICATED BY GAUGE PI-700.8, ADJUST VALVE HV-XXX.4 UNTIL PRESSURE IS STABILIZED. IN THE
EVENT THAT CYCLING PERSISTS, SLOWLY OPEN VALVE HV-XXX.5 (VACUUM STABILIZER) UNTIL PRESSURE
STABILIZES.
SHUTTING DOWN
I) AFTER MAIN TRIP VALVE HAS CLOSED, SHUT OFF WATER SUPPLY TO GLAND CONDENSER AND CLOSE VALVE HV-XXX. 7
LOCATED BETWEEN STEAM STRAINER FC-700.4 AND EJECTOR PE-700.6.
A-6068032 S.O. C-32986 11 OF 11
SUBSEQUENT START-UPS
J) FILL CUSTOMER’S LOOP SEAL LINE WITH WATER.
K) BLOW OFF CONDENSATE FROM EJECTOR STEAM SUPPLY LINE AS DESCRIBED UNDER INITIAL START-UP.
L) OPEN VALVE HV-XXX.7 LOCATED AFTER STRAINER FC-700.3
NOTE
TO AVOID CONTAMINATING THE LUBE OIL, STEAM MUST NEVER BE PERMITTED TO FLOW TO THE ATMOSPHERE THROUGH THE OUTER PACKINGRINGS.
