eg, leaks, ventilation problems, temperature control, etc.)

1. Call 624-2900 (facilities management service desk) to report the problem. For PAN, the dispatcher may not know that the building exists yet - giving them the address may help (115 Union Street SE front door; 140 Harvard St SE dock)
2. Make sure they show up
3. If the situation can be considered fully resolved (let's say an overflowing toilet that is unclogged), then just forget about it. If the situation may be related to a construction issue, such as a leak, then please notify me so I can forward the information.

This sytem runs at much higher presssure than the system in Tate. It can be 100 psi in the basement. You must use properly rated hose and fittings. Fiber reinforced flexible PVC with hose barb fittings is standard. If you are using garden hose, it should be “heavy dut,” and make sure it is rated for at least 125 psig. If you want to use garden-hose style fittings (for example, if you detach cooling water lines frequently), DO NOT use the ones from the chemistry stockroom. Buy the appropriate brass adapters from McMaster Carr. If in doubt, please ask someone from Crowell or Dahlberg groups.

If you are inserting a short piece of hose in your system between two fixed points, you must put a loop in it. If you try to put in short piece without a loop, there will be a significant strain on the fittings, and they are more likely to leak. Do not worry about an extra two feet of hose.

Without getting into technical details: 1. This is a closed system with variable speed pumps. It is separated from the campus sytem by heat exchangers. 2. It is currently quite clean. Most people are putting in filters. Filters are generally to protect your instrumentation, and inserting them is up to you. If you have something full of sludge from the Tate system, please flush it before inserting it into the loop. 3. The water is not supposed to be “cold”. The system is designed to run about the dew point, so that we do not have condensation problems. 4. Most termination points have a bypass, which is currently open. Depending on the impedance of your load, you should close this valve when you hook up your load. Please leave the bypass on unused termination points OPEN.

<note warning> For any life safety emergencies, call 911! To be sure, provide the address and location within the building, in case the phone location information is incorrect (particularly within PAN while moves take place). </note>
