1 TG1Y (388) EMBASSY SERIES SINGLE PACKAGE AIR CONDITIONERS (WATER-COOLED) C2ED060, 090, 120 & 180 5, 7-1/2, 10 & 15 Nominal Tons Each circuit includes a fully hermetic compressor with a crankcase heater and internal line break motor protection, a co-axial condenser with copper tubing inside a steel casing, a high pressure control, a filter-drier, a compressor lockout circuit, an expansion valve, and a full operating charge of refrigerant-22. Units include a one-year limited warranty on all replacement parts and a five-year limited warranty on each compressor. These units have been tested by Underwriters Laboratories and will be shipped with a UL label. DESCRIPTION These units are completely assembled, piped, wired, charged and tested at the factory and are shipped ready for immediate installation. Only the power supply wiring, the thermostat wiring, the condenser water piping, the condensate drain piping and the ductwork are required to complete the installation. The blower section of the 15-ton unit can be removed to simplify rigging on renovation jobs where the equipment may have to be moved through doorways, elevator shafts and/or stairways. All of these vertical, indoor units include a well-insulated cabinet, a centrifugal blower, a 1750 RPM blower motor, an adjustable V-belt drive, 1" throwaway filters, a 24-volt temperature control circuit, 1" flanges for both the supply and return air duct connections, a copper tube/aluminum fin evaporator coil, and either one (CED060) or two (CED090, 120, 180) refrigerant circuits. APPLICATION FLEXIBILITY These "cooling only" units can be applied with: 1. Cooling towers. 2. Well or surface water providing the temperature and the GPM of the water meet the application limitations of the unit. 3. Brackish or salt water and a secondary heat exchanger. They can be installed: 1. Within the conditioned space as "free standing" units without any ductwork. Supply air plenum and return air grille accessories are available for these freestanding applications. 2. In an equipment room with both supply and return air ductwork. Hydronic coils and electric heaters are available for "cooling/heating" applications.

2 TG1Y ACCESSORIES - Field Installed SUPPLY AIR PLENUMS - These fully insulated plenums are available for free standing units located within the conditioned space, are shipped knocked-down for easy field assembly, are finished to match the exterior of the basic unit, and have double deflection grilles that can be adjusted to vary the throw, spread and drop of the supply air. RETURN AIR GRILLES - These expanded metal grilles are available for free standing units located within the conditioned space, are finished to match the exterior of the basic unit and are shipped in one piece for easy installation. HOT WATER COILS - These drainable coils have 2 rows of 1/2" copper tubes, 8 aluminum fins per inch, a casing that is finished to match the exterior of the basic unit, but no water control valve. The coils can be slid out of their casings for easy field installation. STEAM COILS - These non-freeze coils have 1 row of 1" copper tubes, a 5/8" copper tube inside each 1" tube to distribute the steam evenly across the entire length of the coil, 8 aluminum fins per inch, a casing that is finished to match the exterior of the basic unit, but no steam control valve. The coils can be slid out of their casings for easy field installation and are pitched in their casings to facilitate condensate drainage. ELECTRIC HEATERS - Three-phase heaters are available in several capacities to precisely match the heating requirement of the conditioned space. These heaters are designed for easy field installation over the unit s supply air opening, are fully protected against excessive current and temperature by fuses and two high limit thermostats, and are shipped with a UL label. Units with electric heat will require two power supplies - one for the basic unit and one for the heater. ELECTRIC HEAT KIT - This wiring harness is required to interconnect an electric heat accessory with the basic unit. ANTI-CYCLE TIMERS - These timers provide a 5-minute "OFF CYCLE" whenever a compressor shuts down. They include a low voltage cutout that can be adjusted to prevent a compressor from operating when the voltage of the main power supply drops 10% below its nominal rating. WATER REGULATING VALVES - These valves are available to control the flow of condenser water on installations where the temperature of the water may drop below 60 F. These valves reduce water use and maintain more stable operating conditions. THERMOSTATS - Wall-mounted thermostats and subbases (24-volt) with system and fan switches are available to control the operation of "cooling only" units or units with a heating accessory.

Do not install these units outdoors nor in any area where the surrounding temperature may drop below 32 F. 1 The water pressure must be great enough to overcome the pressure drop of the condenser and the condenser water piping. 2 Although the water side is only leak tested for 150 psig, the maximum water-side working pressure of the condenser is 450 psig. Class 150 fittings in the unit s condenser water piping are good for 300 psig. For 300 psig applications, a sealing material ( Locktite or equivalent) must be applied to all threaded connections to assure a leak-tight installation. The water regulating valve accessories are limited to a maximum 150 psig. 3 The limitations for entering condenser water temperature will vary with condenser water GPM. 4 A minimum steam pressure of 5 psig is required if the entering air temperature should drop below 45 F. 2 Unitary Products Group
