5 1. Preface Please read the product specification before 1.1 Product description This series of products are designed for Power industry, Communication industry, Chemical industry or related industrial equipment applications of high-performance ac type air conditioning unit, cabinet internal devices suitable for heat, temperature sensitive, and inside and outside completely isolated applications; 1.2 Working principle The cabinet air conditioning refrigerates the air through inside and outside two independences, and exchanges the heat inside the cabinet to the outside by the heat-exchanger. By this way, it can protect the electricity wind chest's electrical element in the controllable temperature range movement. Simultaneously the cabinet air conditioning has dehumidifies the function, which will guaranteed the cabinet interior has the ideal temperature and the humidity.

Packing and transportation Air conditioner use carton or wooden cases,the package includes Annex The air conditioner during the transportation, please pay attention to the following matters During Handling or transport, Air conditioner must be upward placed as. No inverted, flat, excessive tilt and collision. Air conditioner is precision instrument, in handling or transport process, should be handled with care, package boxes do not step, prohibit standing or placing other heavy objects. During Handling or transporting, pay attention to moisture, water, rain. 3. Installation 3.1 Before Installation You have to prepare the following tools before installation: cross screwdriver, slot type screwdriver, sealing strip, vice. The products are packed in carton. Please remove the strap first, open the upper cover and draw out the carton, then check the accessories according to user manual packing list. 1. After removing cartons, please make sure the unit stands and is never laid down. 2. After removing the carton, please check whether there is any defect or grease spot. If there is, please report the bar code number to distributor within one week. Notice before installation: Avoid any obstacle between inner air outlet of the unit and other equipment in ~ 5 ~

10 the cabinet. Well consider the layout of water draining passage to avoid the deforming of drain pipe or blockage. 3.2 Air Conditioner Installation Installation steps: 1. Check attachments and tools 2. Draw on the cabinet mounting cut-out map according to Figure, cut off the shadow part. Different models of air conditioner cabinet mounting cut-out maps refer to its specification. 3. Stick the sealing damping block between cabinet and air conditioner. 4. Fix the air conditioner into the cabinet. 5. Make water-proof protection. 6. The internal circulation air outlet and the obstacle keep at least 100mm distance,the outer circulation air outlet and the obstacle keep at least 500mm distance. 7. Please to install drain pipe on drain hole and fix with pipe hoop if you need. Double check lists after Installation: 1. Don't apply this unit in high oil, burning gas, explosive gas, strong corrosively condition, the ambient air must be under 55, and the humidity not higher than 95%. 2. Make sure that the lean of the product no more than Make sure that the cabinet should be sealed well to avoid the cooling losing and avoid ambient moisture penetrate into cabinet, this will avoid produce more condensate water. 4. Ensure that the product is up and running in upright 30 minutes. 3.3 Electrical Wiring ~ 6 ~ Does Electrical Wiring according to the manual before use the air conditioner; we suggested preferring to use cables in the attachments. You should call the

11 After-sale Service Department of RIGAO, if you cannot sure the cable specification be made by your-self. Electric wiring should follow below steps: 1. Make sure the power is cut off. 2. Connect the power cable and input terminal according to attached diagram. 3. Connect input terminal on power plug and tighten the screws. 4. Connect the other end of power cable to main power supply. 5. Connect communication cable to signal input terminal according to its definition. 6. Measure power input wire by multimeter to check whether there is a short circuit or an open circuit. 7. Measure signal input wire by multimeter to check whether there is a short circuit or an open circuit. ~ 7 ~

12 4. Operation 4.1 Ⅰ Digital single-cooling series Operation interface Display panel can display three digits, one status indicator (key lock),two parameters descriptors (on temp, off temp). Under normal running status, all descriptors will not light; when enter the menu setting mode, the corresponding parameters descriptor lights. Under normal running status, if there is output, on descriptor lights. Indicator light Symbol Status Meaning Key lock OFF ON Unlocked status Key lock status ON Refrigeration work Refrigeration ON OFF Refrigeration stop FLASH Refrigeration time delay Key description There are in total six keys in the controller: : unlock key/ok : forced defrost key temp key temp key : UP key : DOWN key ~ 8 ~

13 4.1.3 Operation instruction Under the status of controller locking, press for one second, the controller will be unlocked, and the same time, the buzzer beeps for about 0.5 second. If no key operation within 30 seconds, the controller will lock automatically. Parameter descriptor Description Setting range Default setting Work mode Note temp Descriptor lights temp Descriptor lights Start temperature Shutdown temperature Temp~ Refrigeration Temp~ Refrigeration If cabinet temperature is higher than set temperature, the output starts. If cabinet temperature is lower than set temperature, the output closes I / O interface diagram ~ 9 ~

14 4.2 Ⅱ Digital cooling & heating series Operation interface In display panel, it could display three digits,two status indicating symbol(key lock and lighting)for parameter description words(heat on temp., cool on temp., defrost cycle, defrost time) Under normal running status, all parameter description words indicators are off; when it enters to menu setting status, the corresponding parameter description word lights.
