We have heard of the central air conditioning, but the knowledge of the central water purifier is not a lot of knowledge, but by analogy can be learned and central air conditioning, central water purifier also has a central integrated system, can be a batch of water intake operations, especially suitable for installation in the use of the area and the field of wider public **** place, can be a one-time treatment, to provide safe and healthy guaranteed drinking water and use of water for everyone. Health is guaranteed by the drinking water and use of water, the next step is about the central water purifier installation, including step by step instructions as well as the use of operational skills and recommendations.
A,? Site survey
1,? Before the installation of engineering and technical personnel to the customer site and renovation company responsible for water and electricity (or project manager) exchange and communication (has been occupied to find the property management company responsible for water and electricity), the first to find the household water meter and the location of the main valve.
2,? Compliance with the views of customers to determine the location of the central water purifier. Generally placed not far from the water meter and valve, and easy to drain water. Specifically placed in the kitchen, storage room, garage, balcony and garden.
3,? Detailed records of the diameter of the water pipe into the house and the material of the water pipe (PVC, PPR,), rough estimate of the materials required, and make a good record for the drawing of the installation of piping diagrams and installation ready.
4,? Central water purifier sewage pipe outlet should be lower than the water purifier control valve surface, if higher, it is best to install a check valve on the sewage pipe.
5,? The minimum installation space of the central water purifier is 600*600*(h+300)mm, h is the actual height of the central water purifier.
6,? Central water purifier should avoid too close to the heat source, do not let the sun shine directly on the product. If the central water purifier and water heater are too close to each other, be sure to add a check valve.
Two, mapping (occupied customers may not need)
1, ? According to the results of the site survey and the customer's original water layout, marking the direction of sewage, the location of power outlets.
2,? According to the customer's water consumption and water distribution points, to determine the size of the selected pipe diameter (generally not less than the original water pipe), based on the survey data to draw the pipeline layout. Labeling pipe diameter, length, pipe quality.
3,? Draw the actual installation of the inlet and outlet valves and bypass valves of the three-dimensional demonstration map (pipeline installation by the decoration company to provide), marking the height of the central water purifier inlet and outlet pipe interface.
Three? Construction preparation
1, tools ready: hacksaw, pvc scissors, 300 * 45 pipe wrench, 400 * 40 wrench, stylus, screwdriver a set of impact drills, drills, hammers, steel wire cutters, sharp-tipped pliers, thermo-soluble machine, etc., small tools packed with tools.
2, material preparation: three valves, elbows, straight through, water pipes, water tape, etc., according to the piping diagram requires the number and material ready.
3, written documents: installation and commissioning reports, sales agreements, etc.
4, clinical inspection: confirm the customer's name, address, telephone, check whether the tools and materials are complete, and arrive at the scene at the time required by the customer.
Four? Installation and construction
1,? Installation of construction personnel should be equipped with two people, with all the tools and materials needed to enter the construction site, first turn off the main water valve, according to the layout of the water purifier to find a good installation location.
2,? Open the box and take out the "manual", "control valve manual", "warranty card", "certificate of conformity", etc., check the appearance of the water purifier, and make a record.
3.? According to the piping diagram to find the location of the main water pipe disconnect, disconnect the main water pipe according to the piping layout diagram to connect the inlet and outlet valves and bypass valves, pay attention to the bonding process.
4,? In the predetermined position to install fixed water purifier, connected to the inlet and outlet pipes, find the piping diagram of the floor drain or drain, according to the requirements of the installation of the drain.
5.? Wait until the bonding process requires the use of time, open the main entry water valve, test whether the pipeline leakage, while the water purifier for manual positive and negative flushing.
V.? Debugging and explanation
①? Commissioning: set the control valve for flushing state, to be flushed after the completion of the control valve is set to run state, for different control valves, according to the "instructions" required to adjust the control valve, based on the customer's water consumption, estimated flushing time, set on the control valve.
②? Explanation: a person for the customer to explain, another person to clean and restore the installation site. The content of the explanation includes the performance of the whole machine, the service life and the replacement cycle of the filter media, some basic operations of the control valve, the backwash cycle and manual flushing methods, flushing time adjustment.
③? Hand over the water purifier "manual", "control valve manual", "warranty", "Certificate of Conformity" and other information, fill out the installation and commissioning report, indicating the product number, the customer's signature to confirm. Leave the after-sales service phone number, politely say goodbye to the customer.
The above is an example of the central water purifier installation skills and step by step instructions, which can be learned and the principle of central air conditioning has certain similarities, the central water purifier can also have a central control system, through a one-time treatment, batch processing of water quality of each outlet, to protect the health and safety of the controlled water, in addition to the central water purifier can be eliminated! Large and small water purifier product installation costs and storage space, especially suitable for the area of the field is relatively broad public **** place to choose and purchase. Interested friends can refer to the above for advance knowledge.
