The unit is designed to have an external electrical rating approved for Class I, Division 2 / Zone 2, Groups, C, & D / II, II hazardous areas. In addition, the unit is available with a choice of two interior electrical ratings. The first interior electrical rating option is designed and approved for buildings classified as nonhazardous locations as a result of Type Z pressurization in accordance with the NEC - NFP 70, rticles 500 & 501 and the NFP 496. The second interior electrical rating option is rated and approved for Div. 2 / Zone 2, Groups,C, & D / II, II hazardous (classified) locations. Description MODEL CX -WC/HP IR CONDITIONERS & HET PUMPS FOR DIVISION 2 / ZONE 2 HZRDOUS LOCTIONS ECU Division Technical ulletin CX-WC/HP-R2.0 08/12 ebco Model CX-WC/HP Commercial Grade ir Conditioners are self-contained wall mounted units with all necessary components to supply a room or building with recirculated air that is temperature controlled and humidity limited. The HVC system features two isolated sections, stacked one atop the other. The lower section, known as the condenser compartment, contains the condenser coil, condenser fan motor, condenser fan and shroud assembly, compressor, and pressure sensors which supply the unit controls with signals to activate and deactivate the compressor and condenser fan. The upper section, known as the evaporator compartment, contains the evaporator coil, optional heater elements, an evaporator blower wheel and motor assembly, electrical controls and a return air filter element. The units are contained within either a gauge stainless steel or 20 gauge sheet metal housing that features wall surface mounting flanges, ventilation grills on the condenser compartment, and doorway drip shield flanges. The units are intended for use in outdoor locations and feature a weather resistant paint finish, which can also be refinished with white enamel, but can also be painted any custom color requested. Model CX-WC/HP units are intended for use in areas where exposure to a severely corrosive atmosphere is considered unlikely or very infrequent. The unit bottom support bracket, return air filter grille, and supply air register are shipped loose in the crate, to complete field installation. In addition, custom supply ducts with registers can be furnished upon request to distribute air evenly to multiple rooms or the entire length of a large single room.

2 Manufacturing Process Cross Sectional View Starting with documented instructions and a full inspection and operational test of the unit, ebco begins the conversion process in the evaporator compartment, where all electrical components and the evaporator fan are carefully removed and stored for later use. ll commercial grade fiberglass insulation is then removed from the bottom section of the evaporator compartment, and is replaced with industrial grade foil back insulation. In addition, a solid steel bottom plate with mounting rails are added to seal the compartment and accommodate electrical control enclosure mounting brackets. Moving to the condenser compartment, a special wiring enclosure is then fitted to the compressor, and sealed flex conduit and form seven conduit fittings are added to ensure that all high voltage wiring is suitable for a Div. 2 / Zone 2, Group,C, & D / II, II rea. Next, the condenser coil motor and fan blade are replaced with a Div. 2 / Zone 2 UL Listed TENV motor with hermetically sealed thermal overloads and an aluminum spark free fan blade. The unit is then made suitable for either a Nonhazardous or Div. 2 / Zone 2 building interior. For Div. 2 / Zone 2 interiors, the electrical controls and barriers for a Div. 2 / Zone 2 thermostat are installed in a NEM 7 explosion proof enclosure, along with sealed flex conduit, appropriate seals and an evaporator blower, modified to contain a Div. 2 / Zone 2 UL Listed TENV Motor with hermetically sealed thermal overloads and spark free aluminum fan blades. Finally, For Nonhazardous interiors, all electrical controls are placed in a NEM 12 enclosure and the original evaporator fan is reinstalled into the unit, along with jacketed wiring systems for component interconnection. The interior of the unit is silicone sealed at every point of body panel attachment and fitted with a special flange and rear door assembly to provide a positive seal against the entrance of flammable gases or vapors. ll units are then fully inspected and operationally tested to ensure quality of the final product. "22" & "G2" Unit Ratings The most distinguishing difference between CX- WC Models, besides the obvious difference of size, is the classification of the evaporator compartment. s noted above, since the units are intended for use in a Div. 2 / Zone 2, Group, C, & D / II, II Hazardous rea, the condenser compartment components and all associated wiring are rated for Div. 2 / Zone 2 reas. ut the evaporator compartment components are only exposed to the air which is recirculated within uilding. For this reason, ebco designs units that are suitable either for a Nonhazardous interior or a Div. 2 / Zone 2 interior. The units are distinguished by a segment of the Model Number that identifies the unit's electrical rating. rating of "22" represents a unit that is suitable for a Div. 2 / Zone 2 rea both inside and outside of the building or room. rating of "G2" represents a unit that is suitable for a Div. 2 / Zone 2 rea on the exterior of the building or room, but which is only suitable for a Nonhazardous rea within the room or building. The downgraded "G2" unit is therefore, by design, only suitable for building interiors that are rated Nonhazardous, but is offered at a significantly lower price than the "22" units.

"22" Units are also designed and approved for use on analyzer rooms or buildings classified as Class I, Division 2 / Zone 2, Groups,C&D / II, II, if the room or building is ventilated in accordance with NFP 496 section IMPORTNT "G2" & "G1" UNIT NOTES Operation & Service Initial start-up is accomplished by ensuring that the thermostat controller for the HVC system is set to the "off " condition. Power can then be applied to a main disconnect switch for the unit after any conditions such as building pressurization have been satisfied. The HVC system's thermostat can then be set to activate heating or cooling functions. During normal operation, the HVC system will cycle on and off as needed to meet thermal control demands. Power to the HVC system must be disengaged prior to accessing the HVC system evaporator compartment. Please contact a ebco Sales ssociate or refer to the installation, operation and maintenance manual for more information regarding operation. DIVISION I PPLICTION NOTE Type Y purging will be used to protect motors, compressor and conduit system on Units rated for Class I, Division 1, Group Hazardous reas. Contact a ebco Sales ssociate for information. "G2" Units are designed for use on structures with nonhazardous interior ratings as a result of Type Z pressurization in accordance with NFP 496. The structure must contain no internal source of ignitable concentrations of gases or vapors, e.g. analyzer rooms. "G2" Units must be powered by a circuit located after or separate from a disconnect switch for the pressurization unit, in accordance with NFP 496 section Discharge ir Flow IMPORTNT "11" & " 21" UNIT NOTES "11 and 21" as well as "1G, G1 and 12" Units incorporate a Type "Y" pneumatic purging system to render all or some Division 2 rated motors and conduit systems suitable for a Division 1 Group C & D Hazardous reas. User must provide a clean source of instrument air or inert gas that is essentially free of any ignitable concentration of combustible gas, and operate purging system in complete accordance with manufacturer's instructions and NFP 496. ebco Industries, Incorporated Environmental Control Units Division Model CX-WC/HP R2.0 Page 2 of 8 Discharge ir Flow Return Div 2 Condenser Compartment "22" Unit Cut way View Interior & Exterior Rated Class I, Groups C&D / II, II, Division 2 / Zone 2 Optional Fresh ir Make-up Pressurization ir arrier Cond. ir flow Sealed Evaporator Compartment Climate Controlled uilding or Room Interior tmosphere Return Condenser Compartment "G2" Unit Cut way View Interior Rated Non Hazardous Exterior Rated Class I, Groups C&D / II, II, Division 2 / Zone 2
