cooler, etc.), yet provides free air flow. This can cut installation cost by eliminating the need for separate, expensive fencing. (Factory mounted)
•Louvered Panels (condenser coils only) – Painted steel to match unit panels, louvered panels are mounted over the exterior condenser coil faces on the sides of the unit to visually screen and protect coils. (Factory mounted)
•Louvered Panels (full unit) – Painted steel to match unit panels, to protect condenser coils from incidental damage, visually screen internal components, and prevent unauthorized access to internal components.
(Factory mounted)
•Louvered (Condensers)/Wire Panels (Mechanical)
– Louvered steel panels on external condenser coil faces, painted to match unit panels. Heavy gauge, welded

BUILDING AUTOMATION SYSTEM INTERFACE:
•Chiller to accept 4 to 20mA or 0 to 10 VDC input to reset the leaving chilled liquid temperature. (Factory Mounted)
Separate sequencing control center provided to permit control of up to eight chillers in parallel based of mixed liquid temperature (interconnecting wiring by others). (Field Mounted)
VIBRATION ISOLATION:
•Neoprene Isolation – Recommended for normal in stallations. Provides very good performance in most applications for the least cost. (Field mounted)
•1” Spring Isolators – Level adjustable, spring and cage type isolators for mounting under the unit base rails. 1” nominal deflection may vary slightly by appli cation. (Field mounted)
•2” Seismic Spring Isolators – Restrained
Mountings incorporate a rugged welded steel hous- ing with vertical and horizontal limit stops. Housings designed to withstand a minimum 1.0g accelerated force in all directions to 2” (51mm). Level adjustable, deflection may vary slightly by application. (Field mounted)
