ThreeInstallationPreparing
1General sampler installations are often accompanied by online monitoring equipmentCODDue to the online monitoring of ammonia nitrogen, total phosphorus, and total nitrogen, the sampling unit is typically installed as close as possible to the monitoring instruments.
2After confirming the installation location of the sampler, it should be placed flatly. Once placed, the instrument should not shake. A gap should be left between the back of the sampler and the wall.0.6Approximately 3 feet of space on each side should be reserved for connecting pipelines and future maintenance.0.5The space is approximately 3 feet, facilitating cooling for the refrigerator; when placing the sampler in the cabinet, position it as close to the left side as possible and at the front, ensuring that the refrigerator door can be fully opened to remove the sampler tray completely.
3Sample tube connections should be made using rigid tubes, ensuring that the connections are aesthetically pleasing and tidy. It is also crucial to verify that there are no kinks or damage to the tubes after the connection is completed.Please provide the Chinese content that needs to be translated into American English.300mm）All piping is, in principle, non-detachable; for pre-buried piping that needs to pass beneath the road, the pipeline crossing the road should be wrapped with the corresponding specifications.MetalPlease implement protection.。
4All indoor wiring must be installed accordingly.PVCMaterial protection for wire channels or conduits should be selected according to the number of wires to be routed, ensuring the routing is level and perpendicular, as well as aesthetically pleasing and tidy; when connecting to an online monitoring instrument, use wires with the appropriate diameter.0.3mm2Two-core and three-core sheathed cables (with shielding)Copper WireMinimize signal transmission distance to reduce signal loss.
5If there is no fixed five-hole socket at the installation site and you need to connect an extension cord, it is strictly prohibited to place the extension cord on the ground. The extension cord must be secured to a height of ≥600mmAnd≤1200mmEnsure the wall surface is secure during installation to prevent detachment.
6Prior to any circuit connections, make sure that the power supply, control circuits for any high-voltage operations, and circuits with voltages above atmospheric pressure are turned off.

1Prior to unboxing, carefully inspect the packaging box for any signs of wear or damage.
2Inspection EquipmentInspect the condition for any visible dents, dings, warping, or damage and make detailed records.
3Thoroughly inspect the packing components according to the packing list to prevent any damage or missing items during transit.
4Ensure that product manuals and instrument accessories, along with other relevant documents, are properly stored for easy reference.
Section V: Sampling Point Selection
The sampling water intake points should be ideally located at the central flow path of the effluent weir, with the intake front positioned downstream to minimize blockage at the front of the intake section. When measuring mixed effluent, water should be sampled from a location where it is fully mixed after the confluence. The sampling water intake system should be designed to move up and down with the water level fluctuations.
