   OPERATIONS MANUAL OPERATORS MANUAL Supersedes: 155.16-O3 (894) Form 155.16-O3 (797) ABSORPTION LIQUID CHILLERS 28342A MODELS YIA-ST-1A1 THROUGH YIA-ST-14F3 (STEAM) MODELS YIA-HW-1A1 THROUGH YIA-HW-14F3 (HOT WATER)

2. Стр. 3 USING THIS BOOK

   The “Theory of Operation” section provides an overview of the unit control provided by the MILLENNIUM CONTROL CENTER. Unit control is described and operating and status messages that are displayed on the Control Center display are highlighted. The “Operation Flow Chart” can be used as a quick…

3. Стр. 4 Two variations of the Model YIA units are as follows

   • Models YIA-ST-1A1 thru YIA-ST-14F3 with ADC for steam applications. • Models YIA-HW-1A1 thru YIA-ST-14F3 with ADC for hot water applications. Although two applications exist for Models YIA steam and hot water units; namely, standard and FAX-4500 versions, both are accomplished through the use of a…

4. Стр. 5 manual dilution cycle is controlled via the MANUAL

   PUMP key in the Service section of the keypad. The PUMP STATUS key employs a scrolling feature to allow control of the pumps, the manual dilution cycle, and the stabilizer refrigerant solenoid valve via the MANUAL PUMP key. In SERVICE mode, each pump may be operated manually if not already required…

   and 1F is at a higher level than 3F, it is not possible that 1F would be closed if 3F is still open; unless one of the switches is stuck in one position. If this condition is detected, a safety shutdown is performed and “DAY-TIMEREF PUMP FLOAT SW CONFLICT” is displayed. NOTE: the state of each float…

   ing to 30% whenever the generator shell pressure threshold of 10.00 PSIA is reached. During this time, the panel displays the message “SYSTEM RUN-PRESS STATUS” and the warning relay contacts are closed. The STATUS key displays the warning message “HIGH PRESSURE OVERRIDE”. This feature allows the…

7. Стр. 8 manual operation of the refrigerant level solenoid is only

   allowed in MANUAL PUMPS key via the special access code in the PROGRAM MODE. If the refrigerant level solenoid is manually energized (open), it is de-energized (closed) as follows: • Manually, using the DISPLAY DATA key • Automatically, if the mode is changed for SERVICE to LOCAL or REMOTE Whenever…

   ture provides a warning message and limits the maximum load to 60% of the steam or hot water valve position. The feature, which is bypassed for the first 30 minutes of unit operation, is in effect when the entering condenser water temperature exceeds the specified limit for 10 minutes continuously.…

9. Стр. 10 DILUTION

   The dilution cycle occurs at most shutdowns. The dilution cycle is required to prevent crystallization of the lithium bromide solution. During the dilution cycle, the solution (absorber and generator on 50 Hz Models YIA10E3 – YIA-14F3 with Franklin pumps); refrigerant; and chilled and condenser…

    refrigerant pump to start at the beginning of the dilution cycle without any delay. PURGE Since absorption chillers operate at pressures below atmospheric, a purge system is required to remove system impurities which degrade performance and cause internal corrosion. The system employs a purge pump…
