Chillers installed power ready to work: 
1. check whether the supply voltage and phase in accordance with specifications, prior to installing the control plate of identity; 
2. freezing and cooling water hose is connected to piping water from the tap and leave the valves open; 
3. chilled water tank fill water or other frozen media before they can start the pump; (Note: upon request, equipped with refrigerating medium) 
4, please pay attention to the direction of cooling water pump and Tower fan is reversed. Chiller installation procedure: 1. install unit space must be flooring, installation of pads or Foundation, its level within the 6.4mm, and can bear the operating weight of the unit. 2. the unit should be left at room temperature for the 4.4-43.3 ° c room, around and above the unit should have sufficient space to carry out routine maintenance work. 3. at one end of the unit should allow the smoke pipe of condenser Tube bundle cleaning space, openings or other suitable hole is also available. 4. Select appropriate diameters of pipes, turbine cooling system with maximum power and cooling system, and properly connected. 
5. for ordinary applications, through the evaporator and condenser flow rate allowed between 1.0-3.6m/s. 
6. under any load, the water flows should remain stable. 
7. all chilled water and cooling water pipe design and installation should be carried out as usual, chilled water pump is located on the inlet of the unit, in order to ensure positive pressure and flow within the unit. Piping should be damping tube to ensure proper elasticity, but also prevent water pump evaporator water being drained when stop. 
8. solid supports for piping should be independent of the chiller, avoid the stress exerted on the chiller's components.  Hanger sets to facilitate pipeline. 
9. in order to reduce noise and vibration, it is best to install isolator in the line. 
10. in order to effectively and economically use chillers, recommended water treatment expert analysis on evaporator and condenser water, fouling caused by poor water quality can affect heat, or corrosive precipitation, breeding organisms, affect unit performance, increase operating and maintenance costs. 
11. in General, the correct treatment and Tube bundle cleaning on a regular basis to maintain its good performance, if existing water quality conditions do not use the appropriate methods to improve, then it should be considered allowed to tubes have more dirt coefficients or assign special structural materials. 
12. retrofitting of the pipe inlet filter, and cleaned regularly. 
13. the leak test has been completed, all taken over must be treated against rust. 
14. in order to facilitate regular maintenance work, users can take the following measures: a) Plug gauges and valves can be installed in the cooling water and the import and export of frozen water pipe, as close as possible to water chillers; B), equipment can be set up above hanging Rails and beams for easy maintenance. Industrial cold water machine installation of vapor compression cooling type industry cold water aircrew consists of four main components of the vapor-compression refrigeration cycle (compressor, evaporator, condenser, some form of metering device), these machines can achieve different refrigerants. Installation should be aware of the following: i. check if the machine is damaged during installation? choose a suitable place for installation and future maintenance. II. installation site must be flooring, installation of the unit pad or Foundation, its level within the 6.4mm? and can withstand the operating weight of the unit. III. units should be stored at room temperature is 4.4-43.3 degrees Celsius in the engine room? should have sufficient space above and around the unit? in order to carry out routine maintenance work. IV. at one end of the unit should allow the smoke pipe of condenser Tube bundle cleaning space? also available openings, or other right of the hole. V. choosing the right pipe diameter water pipes? maximum power operation of unit when the cooling system and water system? and properly connected. VI. General application? through the evaporator and condenser flow rate allowed between 1.0-3.6m/s. VII. in any load case? water flow should remain stable. VIII. all chilled water and cooling water pipe design and installation should be carried out by conventional methods? on chilled water pumps at the water inlet of the unit? to ensure positive pressure and flow. Piping should be damping tubes to ensure adequate flexibility? or to prevent the evaporator when the pumps shut down water is drained. Pipes should be independent of the water-cooled type industry cold water aircrew of firm support to avoid the stress exerted on the water cooling type industry cold water aircrew member. Hanger sets to facilitate pipeline. IX. in order to reduce noise and vibration the best installation in the line isolator. X. to cost-effective use of water-cooled type industry cold water aircrew recommended water treatment expert analysis on evaporator and condenser water? fouling caused by poor water quality can affect heat? or corrosive precipitation, breeding organisms? affect unit performance? increase operating and maintenance costs. Bus processing machine 11. generally the correct water treatment and Tube bundle cleaning on a regular basis to maintain its good performance? if existing water quality conditions do not use proper methods be improved? then you need to consider allowing larger bundles of dirt coefficient or specify the specific structure of the material. 12. Requests the retrofitting of the pipe inlet filter? and cleaned regularly. 13. leak test all took over after the mouth must be treated against rust. When installed in order to facilitate regular maintenance? users can take the following some (or all) measures: a cock pressure gauge and valve can be installed in the import and export of chilled and frozen water pipes? as close as possible to water cooling type industry cold water aircrew; B equipment can be set up above hanging Rails and beams for easy maintenance.
