2.1.1 Ensure that the filter media cartridges on the Roll-Aire Filters do not exceed a maximum differential pressure of 0.5" W. G. The Roll '.i re fil ters ( AH-F-2A&B, AH-F-3, AH-F-6A&B and AH-F-23A&B) automatically advance at 0.45" W.G as indicated locally on AH-DPI-5254/5258, AH-DPl-5270, AH-DPI-5274/5276 and AH-DPI-5279/5281 res pec.ti vely.
2.1.2 The HEPA filters Medias (AH-F-4/29) should be replacec' when tne differential pressure drop across the filter increases to 2.2 in W.G., as indicated locally by AH-DPI-5271/5273.
2.1.3 Liquid chiller AH-C-8A/B Oil Heaters must be energized for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> prior to starting a compressor, if not remove old oil f
and recharge compressor with new oil.

03/14/79 2.1.5 The charcoal filter Media AH-F-5, (Hepa Unit) siould be replaced when differential pressure drop increases tc ".5 in.
W.G., as indicated locally by AH-DPI-5272.
2.1.6 The cartridge filter section of AH-F-2A/T2 A'
e-37 should be replaced when the differential pressuce drop across the filter increases to 2.0 in. W.G. as indicated locally on AH-DPl-5265/5267 and AH-DP1-5282 respectively.
2.1.7 In the event charcoal filter high temp limit of 302 F is exceeded, verify at multipoint temperature recorder AH-YMTR-5193 h
that the potential fire is out, prior to isolating the deluge system to the filter Unit.
2.1.8 Do not defeat any chiller safety device or anti-recycle feature to start compressor.
Serious compressor damage will occur.
2.1.9 Do not attempt to energize duct heaters unless associated supply fan is in operation.
2.1.10 Do not start Cor. trol Buildiag RW Booster pump (NR-P-2A(23))
unless at least one NR Supply HDR is in service.
2.1.11 The liquid chiller purge unit should only be operated when the unit is running.
2.1.12 Do not exceed a velocity of 600 FPM through the Control Room Bypass Filter Train.
2.1.13 AH-P-1 A/lB should not be rur.ning if AH-C-lo.s/16B is shutdown.
This mode of operation can result in blown rupture discs.

2.2.3 Do not override a fire protectica signal to remove smoke or vators unless the fire is completely out and there is no possitility for reflash.
2.2.4 Do not enter into an cperating fan cooling cabine+ or into an idle unit unless the Assoc. fan control switch is in the PULL-T0-LOCK position.
2.2.5 Replacement of the Hepa Filter Media must be done IAW HP Dept.
Direction to insure radiological hazards are avoided.
2.2.6 Do not attempt to er.u gize any duct r aters unless the supply fans are operating.

Aux. oil pump starts and aux. oil pressure increases to 35-38 psig above system standby pressure.
If adequate oil pressure exists at the end of 10 seconds the compressor will start.
2.
System run indicator will light.
3.
Aux. Oil pump will continu5 to run for 185 seconds and c

4.
After approx. 70 seconds anti-recycle amber indicator will light.
This energizes a 30 minute timer which prevents 2nd start until its completion.
5.
Compressor oil heater de-energizes.
6.
After compressor comes up to speed, the prerotation vanes will automatically open (under control of temperature sensing module) to load the compressor to = 40%.
4.1.4.10 Sicwly advance max. load limit until condenser pressure increases to = 12 psig.
CAUTION:
Compressor will trip on high pressure cutout at 15 psig condenser pressure.
4.1.4.11 As the chill water temperature decreases, continue to slowly raise the max. load limit to maintain = 12 psig condenser pressure.

4_1.4.12 When chill water temperature has reached 45 F, raise max load f
limit to 100%.
I 4.1.4.13 During normal operation the prerotation vanes will modulate in accordance with load requirements.
Should the System heat, load decrease below the minimum compressor loading valve, the los water temp cutout will automatically cycle the compressor on and off to maintain chill water temperature between (38 F) and (45 F).
4.2 i;ormal Opeation.
4.2.1 Control Room.
4.2.1.1 Modulating dampers in the supply, recirculation and exhaust ducts are used to control temperature when the outside air temperature is below 70F. The air is heated by duct heaters if necessary. When the outside air temperature is greater i
than 70F, the modulating dampers are positioned for minimum outside air and cooling is supplied by the chiller units.
Monitor system parameters and adjust thermostats and temperature controllers as required.
4.2.2 Mechanical Equipment Room.
4.2.2.1 The Fan-Coil Unit recirculates air and heats it or cools it as necessary. Monitor system parameters and adjust thermostats and temperature controllers as required.
4.2.3 Catle, Battery and Switchger Rooms.
