M.Building Automation System (EMS) Reset Interface: Chiller to accept 4 to 20mA, 0 to 10 VDC, or discrete contact closure input to reset the leaving chilled liq- uid temperature, or percent full load amps (current limit).

N.Remote Control Panel (Field Mounted): Auxiliary panel for remote user interface for functions normally made at the unit control center

O.Multi-Unit Sequence Control (Field Mounted): Sepa- rate Sequencing control center provided to permit control of up to eight chillers in parallel based on mixed liquid temperature.

P.Sound Reduction (Factory Mounted):

1.Low speed, reduced noise fans

2.Acoustical compressor enclosures

Q.Vibration Isolation (Field Mounted):

1.Neoprene Isolators.

2.1 Inch Deflection Spring Isolators: Level adjust- able, spring and cage type isolators for mounting under the unit base rails.

3.2 Inch Deflection Seismic Isolators: Level adjust- able, restrained mounts in rugged welded steel housing with vertical and horizontal limit stops. Housings shall be designed to withstand a mini- mum 1.0g accelerated force in all directions to 2" (50.8 mm).
