Resumen del manual
This unit contains totally enclosed, permanently lubricated outdoor fan motors and is designed for over/under or downfl ow applications. Standard Features • Dual high-efficiency scroll compressors with internal motor protection for 2-stage cooling • Totally enclosed, permanently lubricated outdoor fan motors • Enhanced copper tube/aluminum fi n coils • Fully charged R-22 systems • Belt-driven, variable-pitch sheave permits multispeed adjustment • Expansion valve evaporator coil • Time delay for compressors sequence • Compressor grommets for vibration isolation • Two independent condenser coils for two-stage operation • High- and low-pressure controls on all systems • Mild ambient switch • Centrifugal fan for quiet and effi cient operation Cabinet Features • Heavy-gauge, zinc-coated steel cabinet with weather- resistant powder-paint fi nish • Fully insulated with blankets of insulation • Vertical discharge with removable grilles • Control box and compressors easily accessible from side access panels • Base rails with fork slots for convenience of handling and added rigidity • Galvanized steel, powder-coated drain pan with .” NPT condensate connection • Factory wiring conveniently arranged to install accessories • Filters are provided with unit (2” disposable) • When properly anchored, meets the 2001 Florida Building Code unit integrity requirements for hurricane-type winds * Full warranty details available at SS-GPCC 4/09Supersedes 6/08 PRODUCT SPECIFICATIONS NOMENCLATURE NOMENCLATURE PCC120 3 A 1, 2, 34 5 6 Unit Type Engineering PCC Packaged Revisions Air Conditioner Nominal Capacity Electrical 090 90,000 BTU/h 3 208-230/3/60 120 120,000 BTU/h 4 460/3/60 ACCESSORIES THERMOSTAT (CHT90-120) Two-stage cool / two-stage heat thermostat with subbase, manual changeover, fan-on or auto. Note: A variety of thermostat configurations can be used on this equipment based on the application needs. For example, our CHTS3660 can be used if two-stage cooling and single-stage heating is desired. ROOFTOP LIFT KIT (RLK90-120) Kit consists of four .” shackles that are used to lift the equipment into position on a roof, etc. The shackles are attached to the mounting holes in the base rails. Wire or strap material along with field-supplied spreader bars are employed to complete the lifting assembly (see rigging detail). LOW AMBIENT CONTROL (LA-01) Liquid temperature- (or pressure-) operated solid-state control that varies the speed of one of the condenser fans. Low ambient control reduces fan motor RPM as liquid temperature (or pressure) decreases. Caution: If control is used below 50 °F, accumulators should be added to the equipment to avoid slugging of the compressors. ROOF CURB (PGC-5) Full perimeter curb for equipment in the down discharge application. Curb includes provisions for duct attachment prior to setting unit. Curb is shipped knocked down with all necessary hardware and gasket material. MANUAL AND MOTORIZED FRESH AIR DAMPERS (PGMD-5 & PGMDM-5) Manual damper is fixed position type for 0% to 25% fresh air. Motorized damper is a field-adjustable mechanical damper for 0% to 25% fresh air. Damper automatically closes when blower stops. ECONOMIZERS : (PGED090/102-5A & PGED120/180-5A, PGEH090/102-5 & PGEH120/180-5) Fully modulating, enthalpy-controlled economizers shipped with major components pre-assembled. Plug assembly on equipment and economizer provides easy foolproof wiring. HORIZONTAL DUCT KIT (PGHDK090/102-5A & PGHDK120/180-5A) The unit is shipped in the downflow (vertical) duct configuration. The horizontal duct kit must be installed in the field for horizontal duct confi guration. PANEL LOUVER KIT (PLK090/102-5 & PLK120/180-5) Louvered panels for condenser coil protection. HEAT KIT ACCESSORY Slide-in heat kit from 20kW, 30W and 40kW can be used in 7.- to 10-ton models. 2 SS-GPCC PRODUCT SPECIFICATIONS SPECIFICATIONS Cooling Capacity Total BTU/h Sensible BTU/h . EER .
