Labor Day Weekend Maintenance

v

The Central Utility Plant of the Facilities Management Department on the Evanston Campus will be shut down to perform routine annual maintenance beginning Friday, September 2, 2016, at 6:00 p.m. Normal operations will resume on Monday, September 5, 2016, at 10:00 p.m. (Labor Day weekend). This shutdown is essential and is scheduled during this period to cause the least inconvenience to occupants of the affected buildings. There will be no deviation from this schedule.

The exact effect of this shutdown will vary from building to building; but, in general, those buildings normally serviced by the central steam and chilled water system will not have heating or hot water and will have no air conditioning except for science buildings. Shutdown details for science buildings are provided below.

If you have questions or require additional information, please contact Facilities Management:

1. Hot and cold water from faucets in washrooms, drinking fountains, laboratories,
emergency showers, eyewash stations, and all reverse osmosis-deionized (RO-DI) water
systems.
2. Process chilled water for equipment cooling
3. Ventilation and air conditioning - outdoor air supply and exhaust (general and fume hood) fans in varying durations

CATALYSIS CENTER

1. Hot and cold water from faucets in washrooms, drinking fountains, laboratories, emergency showers, eyewash stations, and all reverse osmosis-deionized (RO-DI) water systems.

(Friday, September 2, 6 p.m. through Saturday, September 3, 2016, 7 a.m.)
1. Ventilation – outdoor air supply and exhaust (general and for fume hoods)

COOK HALL

Return to top of page

1. Hot and cold water from faucets in washrooms, drinking fountains, laboratories, emergency showers, eyewash stations, and all reverse osmosis-deionized (RO-DI) water systems.
2. Autoclaves and glass washers
3. Intermittent at reduced capacity: Outdoor air supply fans and exhaust fans for laboratories, offices, and fume hoods including those for perchloric acids and radioisotopes.
Very important: With sashes closed, vapor concentrations inside hoods could rise and cause reactions between vapors, liquids, and solids in open containers. Close all fume hood sashes and cover containers of all fume-generating materials inside fume
hoods.
4. All cleanroom recirculating fans
5. Cleanroom scrubber feed water pump - scrubber must be shut down
6. Cleanroom make-up air for positive pressurization
7. Cleanroom exhaust fans EF-1 and EF-2 serving cleanroom gas cabinets, equipment
shrouds, gas panel exhaust, exhaust drops, and gas vaults

Note: Throughout the shutdown period, chilled water feeding the cleanrooms’ four recirculating
fans will be shut off to avoid over-cooling.

operating at reduced capacity

(Saturday, September 3, 2016)
1. Hot and cold water from faucets in all washrooms, laboratories, emergency showers,
eyewash stations, drinking fountains,
2. RO/DI water system, CCM automatic watering system.
3. Laboratory vacuum system.
4. Process chilled water for equipment cooling.

Note: Electrical shutdown for Pancoe Hall – Details will be issued separately

RYAN (NANOFABRICATION) HALL

Return to top of page

1. Hot and cold water from faucets in washrooms, drinking fountains, laboratories,emergency showers, eyewash stations, and all reverse osmosis-deionized (RO-DI) watersystems.
2. Laser labs (Harel - Ryan B013 and Wasielewski - Ryan B011): The lack of reheat and trim temperature control will have a direct effect onrelative humidity in these spaces. There are several available options for controlling the HVAC systems in these spaces; FM will be discussing with the respective lab managers to select the preferred strategy for each space.

Note:  Upon restoration of normal operation on Monday, Sep. 5, it could take up to 72 hours for target environmental parameters and stability to be re-established.

(Sunday, September 4, 6 p.m. through Monday, September 5, 2016, 7 a.m.)
1. Outdoor air supply and exhaust (general and fume hood) fans will be operating at reduced capacity

1. Hot and cold water from faucets in washrooms, drinking fountains, laboratories,emergency showers, eyewash stations, and all reverse osmosis-de-ionized (RO-DI) watersystems.
2. Autoclaves and glass washers
3. Temperature and humidity control of ventilation
4. All fire alarm strobes (flashing) and horns (noise) will be individually tested as part of the Tech Inst fire alarm replacement project. While testing these devices, ventilation will be interrupted for up to 10 minutes, on a zoned basis.
5. Laser and AFM labs: The lack of reheat and trim temperature control will have a direct effect on relative humidity in these spaces. There are several available options for controlling the HVAC systems in these spaces; FM will be discussing with the respective lab managers to select the preferred strategy for each space. Note that upon restoration of normal operation on Monday, Sept 5, it could take up to 72 hours for target environmental parameters and stability to be re-established.

Note: Coldrooms and server clusters that will be affected by any chilled water shutdowns will be discussed, with their respective departments.
