DESCRIPTIONThese air-cooled package chillers are factory piped, wired and charged with Refrigerant 22. Rugged, weatherproof construc-tion and compact design make them ideal for rooftop or ground level installation. Upward discharge airflow minimizesdirectional sound and dissipates heat away from surrounding areas.

FEATURESStandard one-year warranty.

Multiple reciprocating serviceable-hermetic compressors mounted on spring iso-lated rails. Automatically reversible oil pump, thermal overload protection, suc-tion and discharge service valves.

Electronic ground current sensing device for each circuit.

Calibrated, ambient compensated magnetic-trip circuit breakers with manualreset provide single-phase and phase-reversal protection.

Insert-type 180-watt crankcase heaters.

High- and low-pressure safety switches.

Dual refrigerant circuits. Each refrigerant circuit contains: Hot gas muffler foreach compressor, excessive pressure relief device, liquid line shut-off valve,replaceable-core filter drier, moisture indicating sight glass, loss of oil pressureprotection.

Electronic expansion valve in each refrigeration circuit.

Automatic lead-lag feature automatically alternates the lead circuits to ensureeven compressor cycles and run time.

Single point main power connection.

Compressor timed pumpdown cycle at start-up and stopping of each refrig-eration circuit cooling cycle.

Unit capable of starting with up to 95° F water entering the cooler, with 125° Foutdoor air.

Units are capable of starting and operating down to 0° F outside-air tempera-tures with wind baffles installed. Below 0° F outside-air temperature, the unitmust be modified for low-ambient operation. Below 32° F, unit must be equippedwith wind baffles.

Control capacity based on leaving water temperature, compensated byreturn water temperature.

Low water flow detection provided by internal control devices.

Cooler flow may be either constant or variable.

Provisions can be made for reset by either outdoor, space, or return-water tem-perature. (Return standard.)

8-Digit alphanumeric diagnostic display and set point panel for set points, serv-ice diagnostics and operational quick tests. Displays chiller temperatures, pres-sures (including oil), set points, and accumulated starts and run time for eachcircuit.

Integral shell-and-tube cooler with dual refrigerant circuits, expanded poly-vinyl chloride insulation (and electric heater cable for freeze protectionoptional).

Non-ferrous condenser coils with mechanically bonded plate fins and integralsubcooling circuit.

Direct-drive condenser fans and motors are supported by a formed-wire mountto reduce vibration.

Fan motors are three-phase with permanently lubricated ball bearings andinherently protected.

Multiple fans are used for head pressure control during intermediate season.

Unit can be equipped (accessory) with a two-point demand limit control (each0-100%) activated remotely by an electric signal.

The unit cabinet consists of galvanized steel casing, zinc phosphatized, withan electrostatically applied baked enamel finish, capable of withstanding a500-hour salt spray test.

Hinged control box access panels.

Alarm circuit wiring standard, field-supplied bell required.

7-Day time schedule.
