General Information

The integral air-cooled unit, model SCIH, is a high efficiency, vertical air cooled air conditioner. Units have either front or top discharge configuration options and easy service access. Unit construction is heavy gage steel with a baked enamel finish. Available unit voltages are 208/3/60, 230/3/60, and

460/3/60, 575/3/60.

Refrigeration Circuits

Units are configured in single or double refrigeration circuits. Each circuit consists of a:

high efficiency scroll compressor mounted on rubber isolation grommets

condenser and evaporator coils, designed for optimum performance and efficiency with lanced fins and rifled tubing,

and filter-drier.

Evaporator Section

The evaporator fan section consists of one or two forward curved centrifugal fans powered by a premium efficiency motor through an adjustable motor sheave, and fixed diameter blower pulley.The condenser fan section consists of one or two forward curved centrifugal fans powered by a premium efficiency motor through an adjustable motor sheave and fixed diameter blower pulley. Condenser motor belt tension is adjusted by an adjustable motor mounting base.

Control box access is from the front of the unit to ease electrical hook-up.

Controls

The standard control panel consists of a high voltage terminal block, overload relays for each fan motor, transformer, 3- pole 24 volt contactors for each motor and compressor, and a 5-second delay timer. Remote thermostat controls are field-installed.

Field Installed Accessories

These items ship separately for field installation:

steam coil

hot water coil

plenum

low ambient damper

oversized motors

remote thermostat

Note: Application of the above options and/or accessories may require field adjustment of fan speeds to ensure proper airflow and performance.

Unit Nameplate

The unit nameplate identifies the unit model number, appropriate service literature, and wiring diagram numbers. It is mounted on the control panel door. Reference this information when making inquires or ordering parts or literature.
