2. Where will the thermostats be located? In the room where the Fan Coil is located

3. Please confirm the contractor is not required to convert the existing 2-pipe system to a 4-pipe system under this contract (ie. Will occur under a separate solicitation).

The 4-pipe is being completed under a separate solicitation.

4. It is assumed that this project will be completed prior to completion of 4 pipe system being this project has not been put out for bid to date. By sequencing the project this way please advise on the following information:

• The units will only be able to run in cooling mode until completion of the future 4 pipe system. Yes

• Please confirm the contractor is to connect the new FCUs to the existing 2-pipe system which will require the facility to manually control heating and cooling of the units until the 4-pipe system is installed. The T-Stats installed in the room will control cooling until the 4-pipe system is installed.

• Will the future contractor be responsible for final connections after completion of 4 pipe system or will the contractor installing initial fan coil units under this contract have to return to make final connections and balance the system? The equipment manufacturer would need to be consulted to ensure the warranty will not be impacted. The two pipe connections to hot water will be terminated next to the cooling pipes connections.

• In routing the 4-pipe system under separate contract, will all 4 pipes be replaced or only two pipes added for a revised total of 4 pipes? Only two pipes added for a revised total of 4 pipes
