1 (791) SPLIT-SYSTEM AIR-COOLED CONDENSING UNITS 50 AND 60 HZ H1CE180 & AND 20 NOMINAL TONS (60 HZ) 13 AND 17-1/2 NOMINAL TONS (50 HZ) SUNLINE 2000 DESCRIPTION These Sunline 2000 units are completely assembled, piped and wired at the factory to provide one-piece shipment and rigging. Each unit is pressurized with a holding charge of refrigerant-22 for storage and/or shipping. The compact design, clean styling, and quiet operation make these condensing units suitable for almost any outdoor location. On rooftops... because they weigh much less than a single package unit of similar capacity and are much easier to rig and support. At ground level... because their ample sub-cooling capacity allows them to be located 18 meters (60 feet) below the evaporator coil. All sheet metal parts are constructed of commercial grade (G90) galvanized steel. After fabrication, each part is thoroughly cleaned to remove any grease or dirt from its surfaces. The external parts are then coated with zinc phosphate and finished with a desert sand baked enamel to assure a quality finish for many years. This UL approved coating system has passed the 250 hour, 20% salt spray test per ASTM Standard B117. All models include a 1-year limited warranty on the complete unit. An additional 4-year extended compressor warranty is available as an option on all models. A matching line of Blower units is also offered to meet your precise capacity and air handling requirements. Refer to Form TG4YI(150 & 180) or TG5YI (240) for more information on this air side equipment. FEATURES Condenser coil constructed of rifled copper tubes and louvered aluminum fins for durability and long lasting efficient operation. The coil fins are protected with a decorative grille. 208/230/460 VOLT ONLY 208/230/575 VOLT ONLY Permanently attached base rails with fork lift slots and lifting holes. This design allows for 3-way fork lift access and overhead rigging. Both high and low pressure controls. Since these controls are self-contained, there are no capillary lines to be damaged. Solid state (H*CE180 & 240) or internal line break (H*CE150) motor protection to prevent the compressor from operating at an unsafe condition. A low oil-pressure control with manual reset for additional compressor protection. Pumpdown on all H*CE240 models. A pumpdown accessory is available on all H*CE150 and H*CE180 models. Totally enclosed, three-phase ball bearing condenser fan motors for reliable and efficient operation. Color-coded power and control wiring for easier service and troubleshooting. Anti-short cycle timer to protect the compressor. A lockout circuit to prevent the unit from cycling on safety control. A 24-volt temperature control circuit. Low ambient operation to 4 C (25 F). A filter-drier and a moisture indicating sight glass (shipped in the unit s compressor compartment for field installation near the evaporator coil). Service valves with a back-seating access port for pressure testing the system. Copper stub-outs are factory mounted on the suction and liquid service valves to simplify the field piping connections. Separate panel for easy access to the control box without affecting air flow across the condenser coil. An access opening in piping panel to accommodate gauge lines to refrigerant fittings in the unit. Packaging suitable for outdoor storage.

Friction Loss 4,5 (PSI/100 Ft.) All horizontal suction lines should be pitched at least 1 inch every 20 feet in the direction of the refrigerant flow to aid the return of oil to the compressor. 2 Every vertical suction riser greater than 3 feet in height should have a P trap at the bottom to facilitate the return of oil to the compressor. Use short radius fittings for these traps. 3 Based on Refrigerant-22 at the nominal capacity of the condensing unit, a suction temperature of 40 F and a liquid temperature of 105 F. 4 Although suction lines should be sized for a friction loss equivalent to a 2 F change in saturation temperature (or approximately 3 psi), sizing the lines for the proper return of oil is more important. 5 These friction losses do not include any allowances for valves or fittings. 6 Since the refrigerant gas velocity may be too low to maintain good oil return up a vertical riser, use the next smaller size. The larger size may be used for horizontal runs for a lesser pressure drop.

If the pressure drop exceeds 40 PSI, the liquid refrigerant could flash before it reaches the expansion valve. This flashing will not only cause erratic valve operation and poor system performance, but could also damage the expansion valve. Liquid Line 2 Inches, O.D.
