Allow the compressor to run for a short time, being ready to stop it immediately if any unusual noise or other adverse condition should develop. When starting the compressor, always make sure the oil pump is functioning l properly. The compressor oil pressure gauge is located on the centrol panel. Note that compressor nil pressure must be 6 to 20 psig higher than suction pressure; the latter being shown on the suction pressure gauge. Chiller Safety and Goeratino Controls Operating failure by any of these safety devices causes the indicating light associated with it to illuminate. An l electrical manual reset by the selector switch is required to re-start the unit. Note that being automatic reset devices, once the control resets, the indicating lamp goes out.

2104-5.5 2 Revision 0 06/12/76 i NOTES: (1) The above psig values are average based on a rated flow (GPM). Actual flow depends upon several factors including dimensional tolerance on shell, cleanliness of shell or tubes, etc. The temperature values listed are based on maximum design values. (2) For additional operating data applicable to chiller and condenser, refer to York Instructions, Form 150.21-NM1. (3) Temperature indicating controller AH-TIC-5754, set at U 56 F, reg'alates chilled water flow through AH-C-36 cooling coil by controlling three way valve AH-V-35. (4) Alternate operation of Liquid Cooler Pumps as necessary to balance operating time. (5) Alternate operation of S.B. River 'Jater Booster Pumps as necessary to balance operating time. (6) Periodically check that expansion tank level is about 2/3 full on local level sight glass. (7) Abnormal chiller operation or unit trip is indicated on chiller panel. (8) Periodically sample liquid cooler system water and maintain required chemistry specs. 4.2.2 Main Supply System (Multizone Unit ) AH-C-36 General system operation is monitored on panel 315.

2104-5.5 Revision 0 2 06/12/76 by lights on the panel. System filter dP's are indicated i locally. Periodically check room temperatures vs. thermostat settings and adjust as necessary. Alternate operation of AH-E-23A and 23B exhaust fans as necessary to balance running times. Soiled exhaust fan flow is recorded on AH-FR-5720 at panel 315; flow should be about 7300 cfm. 4.2.3 Mechanical Equipment Room System Starting fan coil unit AH-C-24 energizes its related electric pneumatic control to deliver air to the control circuit. Space thermostat AH-TS-5473 controls water flow through the cooling coil by modulating valve NR-V-73. A rise in space temperature increases water flow through the cooling coil and a temperature decline reduces the water flow until all water flow through the coil is stopped. Turning the fan off causes f valve NR-V--212 to close. With a further decline in space temperature, the thermostat progressively energizes the 4 increments of heating on the heating coil until full heating capacity is obtained. When starting fan coil unit AH-C-24 the electric pneumatic control also opens damper D5742 to bring in 500 cfm of makeup air. Equipment room temperature is indicated on recorder AH-YMTR-5741. Fan opertion and air fis s are indicted by lights on panel 315. Filter AH-F-26 dP is indicated locally.

~ 2104-5.5 Revision 0 ~ 06/12/76 4.2.4 Water Lab Hood Supply and Exhaust System The water laccratory hood supply and exhaust system normally ventilates the fume hood with outside air. When fan AH-E-27 is startad the supply fan, AH-E-33, also starts and damper ED5751 closes via AH-E-27, thus diverting air from the room to the hood and exhausting to atmosphere. Supply air flow and exhaust air flow are indicated on panel 315. 4.3 Shutdown 4.3.1 Liquid Chiller System INITIAL EACH STEP 4.3.1.1 Verify no requirement for chilled water ficw to cooling coil unit in AH-C-36. 4.3.1.2 To shut down the chiller units, place each STOP-OFF-AUTO switch to the 0FF-PUMP COWN position. The compressor will pump down to the low pressure cutout setting. When the compressor stops, the crankcase heater will come on and boil off any refrigerant that may have migrated into the crankcase during the off period. The source of power to the control circuit must remain on to energize the crankcase heater. NOTE: To shut down the unit for long periods such as over a winter season, the compressor should be pumped down and the control and power circuits turned off and the compressor service valves closed. 4.3.1.3 Shut down the Service Building Liquid Cooler Pumps by turning both the A and B control switches to STOP (local i or Panel 315). lbb 14.0

2104-5.5 Revision 0 1 06/12/76 NOTE: If there is no cooling water flow demand from Mechanical Room Fan-Coil unit AH-C-24, shut down the S.B. River Water Booster pumps to prevent prolonged operation at shut,ff head. River water booster pump flow is indicated on Panel 315. 4.3.2 Main Supply System (Multizone Fan Coil Unit) AH-C-36 INITIAL EACH STEP 4.3.2.1 Verify Liquid Chiller Unit it shut down per Shut Down Section 4.3-A. 4.3.2.2 At panel 315, shut down Multizone Fan Coil Unit AH-C-36 by placing its control switch in 0FF. (Local STOP switch may also be used). Check that clean Exhaust Fan AH-E-28 also shuts down. 4.3.2.3 Shut down Return / Exhaust Fan AH-E-26 by placing its control switch in OFF. 4.3.2.4 Shut down Soiled Exhaust Fan All-E-23A and B by switching both units to 0FF. NOTE: Do not switch Soiled Exhaust Fans off if there is any possibility of radioactive contamination in areas exhausted by these fans: a) Contaminated Drain Tanks and Pumps b) Hot Instrument Storage c) Hot Instrument Pepair Shop } d) Decontamination Room e' Fersonnel Air Lock f) Sciled Laundry Areas g) Soiled Rest Roorns and Corridor 186 130 h) Monitor A: ea 15.0 L_.=_~~~-
