FORM 201.18-EG1

•MULTI-UNIT SEQUENCING – A separate Se- quencing Control Center is provided to handle se- quencing control of up to eight chillers in parallel based on mixed liquid temperature (interconnect- ing wiring by others). See Form 150.00-SG2 for more information. (Only one of the following op- tions can be offered on a unit at a time: BAS, Re- mote Control Panel or Multi-unit Sequence Con- trol). (Factory mounted).

•UNIT ENCLOSURES –

♦Wire Panel Enclosure (Full Unit) – UV stabilized black polyvinylchloride coated, heavy gauge, welded wire mesh guards mounted on the exte- rior of the unit. Protects condenser coil faces and prevents unauthorized access to refrigerant com- ponents (compressors, pipes, cooler, etc.), yet pro- vides free air flow. This can cut installation cost by eliminating the need for separate, expensive fenc- ing. (Factory mounted)

♦Louvered Panel Enclosure (Full Unit) – Heavy gauge louver panels, galvanized and painted just as the main unit cabinet, provide liberal free air flow area. Cover coils and around the bottom of the unit to protect condenser coils, visually screen mechanical elements, and prevent unauthorized access to refrigerant components. (Factory mounted)

♦Louvered Panels (Condenser Coil Only) – Lou- vered panels are mounted over the exterior con- denser coil faces on the sides of the unit to visu- ally screen and protect coils. (Factory mounted.)

♦Louvered (Condensers) / Wire (Mechanicals) – Louvered panels mounted over the exterior con- denser coil faces, and heavy gauge welded wire mesh guards mounted around the bottom of the unit. Visually screens and protects coils, and pre- vents unauthorized access to refrigerant compo- nents. (Factory mounted.)

•HIGH STATIC FANS –

Fans and motors suitable for High External Static conditions to 0.4 inches of water (100Pa). Since these require higher power motors and therefore slightly reduce chiller efficiency, select only if the installation conditions will impose additional air flow resistance resulting from such things as field installed:ducts, filters, sound enclosures, or similar obstructions to airflow. Contact the factory for per- formance or electrical implications.

•SOUND REDUCTION OPTIONS –

One or both options may be employed by the sys- tem designer as normally generated machine noise is considered in the overall project design. See Form 201.18-ES1 for additional information.

♦Low Speed Fans – With this option, the basic chiller is equipped with 8-pole condenser fan mo- tors in lieu of the standard 6-pole motors, plus special fans matched to these optional slower mo- tors to retain appropriate airflow. The net result is reduced fan generated noise with no adverse ef- fect on the chiller capacity or efficiency perfor- mance.

♦Compressor Sound Enclosures – Compressor acoustically treated to attenuate noise.
