4.8 Water quality control
4.8.1 Water quality control
When industrial water is used as chilled water, little furring may occur; however, well water or river water, used as chilled water, may cause much sediment, such as furring, sand, and so on. Therefore, well water or river water must be filtered and softened in softening water equipment before flowing into chilled water system. If sand and clay settle in the evaporator, circulation ofchilled water may be blocked, and thus leading to freezing accidents; if hardness of chilled water is too high, furring may occur easily, and the devices may be corroded. Therefore, the quality of chilled water should be analyzed before being used, such as PH value, conductivity, concentration of chloride ion, concentration of sulfide ion, and so on.

4.9 Installation & regulation guide for target flow controller
4.9.1 Please carefully check flow switches before conducting installation of the target flow controller. Packing should be in good condition, and the appearance should be free of damage and deformation. If any problem, please contact the manufacturer.
4.9.2 Flow switches can be installed in the horizontal pipeline or the vertical pipeline with upward flowing direction but cannot be mounted in the pipeline with downward flowing direction. The inlet water of gravity should be taken into account when flow switches are installed in the pipeline with upward flowing direction.
4.9.3 Target flow controller must be installed on a section of straight-line pipeline, and its both ends must be supplied with straight-line pipes whose length is at least 5 times diameter of the pipe. In the meanwhile, the fluid flowing direction in the pipeline must be consistent with the direction of arrow on the controller. The connection terminal should be located where wiring connectioncan be easily done.
4.9.4 Pay attention to the following items when conducting installation and wire connection: a. Collision of the wrench with the soleplate of the flow switch isprohibited, since such collision may cause deformation andfailure of the flow switch.b. To avoid electric shock and damages to the devices, thepower supply should be cut off, when wires are connected oradjustment is done.c. When wiring connection is conducted, adjustment of otherscrews except connection terminals of micro switches andground screws is prohibited. In the meanwhile, over great forceshould not applied when wires of micro switches are connected,otherwise micro switches may suffer displacement, thus leadingto failure of flow switches.d. Special grounding screws should be used for earthconnection. Bolts should not be installed or removed at will;otherwise flow switches may suffer deformation and failure.e. Flow switches have been set at minimal flow value prior toex-factory. They should not be adjusted below the ex-factorysetting value, or they may suffer failure. After installing flowswitches, please press the flow switch lever several times tocheck them. When the lever is found not to respond with“clatter”, rotate the screw in a clockwise direction, until “clatter”occurs.f. Be sure to determine the model of target slice according tothe rated flow of the unit, the diameter of the outlet pipe and theadjustment range of the target slice of the flow switch. Besides,the target slice should not contact with other restrictors in thepipeline or on the inner wall of the pipeline, or the flow switchcannot be reset normally.
4.9.5 Determine whether the flow switch and the system connected with it are in good operation according to the measured value by flow meter, namely, when the measured value on flow meter is less than 60% of rated water flow of the unit, the target flow controller should be cut off and observed for 3 working periods, and it should be covered with flow switch shell timely.

8.7 Winter shutdown
For shutdown in winter, the surface of the unit outside and inside should be cleaned and dried. Cover the unit to prevent dust. Open discharge water valve to discharge the stored water in the clean water system to prevent freezing accident (it is preferable to inject antifreezer in the pipe).
8.8 Replacing parts
Parts to be replaced should be the ones provided by our company. Never replace any part with different part.
8.9 First startup after shutdown
The following preparations should be made for re-startup of unit after long-time shutdown:1) Thoroughly check and clean the unit.2) Clean water pipe system.3) Check pump, control valve and other equipments of water pipesystem.4) Fix connections of all wires.5) It is a must to electrify the machine 12 hours before startup.
8.10 Refrigeration system
Determine whether refrigerant is needed by checking the value of suction and discharge pressure and check whether there is a leakage. Air tight test must be made if there is a leakage or parts of refrigerating system is to be replaced. Take different measures in the following two different conditions from refrigerant injection.1) Total leakage of refrigerant. In case of such situation, leakagedetection must be made on the pressurized nitrogen used for thesystem. If repair welding is needed, welding cannot be made untilall the gas in the system is discharged. Before injectingrefrigerant, the whole refrigeration system must be completely dryand of vacuum pumping.● Connect vacuum pumping pipe at the fluoride nozzle atlow-pressure side.● Remove air from the system pipe with vacuum pump. Thevacuum pumping lasts for above 3 hours. Confirm that theindication pressure in dial gauge is within the specified scope.● When the degree of vacuum is reached, inject refrigerant intothe refrigeration system with refrigerant bottle. Appropriate amountof refrigerant for injection has been indicated on the nameplateand the table of main technical parameters. Refrigerant must beinjected from the low pressure side of system.● The injection amount of refrigerant will be affected by theambient temperature. If the required amount has not beenreached but no more injection can be done, make the chilledwater circulate and start up the unit for injection. Make the lowpressure switch temporarily short circuit if necessary.2) Refrigerant supplement. Connect refrigerant injection bottle onthe fluoride nozzle at low-pressure side and connect pressuregauge at low pressure side.● Make chilled water circulate and start up unit, and make the lowpressure control switch short circuit if necessary.● Slowly inject refrigerant into the system and check suction anddischarge pressure.
Maintenance of main parts● Close attention should be paid to the discharge and suctionpressure during the running process. Find out reasons andeliminate the failure if abnormality is found.● Control and protect the equipment. See to it that no randomadjustment be made on the set points on site.● Regularly check whether the electric connection is loose, andwhether there is bad contact at the contact point caused byoxidation and debris etc., and take timely measures if necessary.Frequently check the work voltage, current and phase balance.● Check the reliability of the electric elements in time. Ineffectiveand unreliable elements should be replaced in time.
8.6 Removing scale
After long-time operation, calcium oxide or other minerals will be settled in the heat transfer surface of the water-side heat exchanger. These substances will affect the heat transfer performance when there is too much scale in the heat transfer surface and sequentially cause that electricity consumption increases and the discharge pressure is too high (or suction pressure too low). Organic acids such as formic acid, citric acid and acetic acid may be used to clean the scale. But in no way should cleaning agent containing fluoroacetic acid or fluoride should be used as the water-side heat exchange is made from stainless steel and is easy to be eroded to cause refrigerant leakage. Pay attention to the following aspects during the cleaning and scale-removing process: ● Water-side heat exchanger should be done be professionals.Please contact the local air-conditioner customer service center.● Clean the pipe and heat exchanger with clean water aftercleaning agent is used. Conduct water treatment to prevent watersystem from being eroded or re-absorption of scale.● In case of using cleaning agent, adjust the density of the agent,cleaning time and temperature according to the scale settlementcondition.● After pickling is completed, neutralization treatment needs to bedone on the waste liquid. Contact relevant company for treatingthe treated waste liquid.● Protection equipments (such as goggles, gloves, mask andshoes) must be used during the cleaning process to avoidbreathing in or contacting the agent as the cleaning agent andneutralization agent is corrosive to eyes, skins and nasal mucosa.
8.5 Care and maintenance
Maintenance period It's recommended that before cooling in summer and heating in winter every year, consult local air conditioner customer service center to check and maintain the unit, to prevent air conditioner errors which bring inconvenience to your life and work.
● Connection must be renewed after injection is completed.● Never inject oxygen, acetylene or other flammable or poisonousgas to the refrigeration system at leakage detection and air tighttest. Only pressurized nitrogen or refrigerant can be used.

8.11 Disassembling compressor
Follow the following procedures if compressor needs to be disassembled:1) Cut off the power supply of unit.2) Remove power source connection wire of compressor.3) Remove suction and discharge pipes of compressor.4) Remove fastening screw of compressor.5) Move the compressor.
8.12 Auxiliary electric heater
When the ambient temperature is lower than 2℃, the heating efficiency decreases with the decline of the outdoor temperature. In order to make the air-cooled heat pump stably run in a relatively cold region and supplement some heat lost due to de-frosting. When the lowest ambient temperature in the user’s region in winter is within 0℃~10℃, the user may consider to use auxiliary electric heater. Please refer to relevant professionals for the power of auxiliary electric heater.
8.13 System antifreezing
In case of freezing at the water-side heat exchanger interval channel, severe damage may be caused, i.e. heat exchange may be broken and appears leakage. This damage of frost crack is not within the warranty scope, so attention must be paid to antifreezing. 1) If the unit that is shutdown for standby is placed in anenvironment where the outdoor temperature is lower than 0℃, the water in the water system should be drained.
2) Water pipe may be frozen when the chilled water target flowcontroller and anti-freezing temperature senor become ineffectiveat running, therefore, the target flow controller must be connectedin accordance with the connection diagram.3) Frost crack may happen to water-side heat exchanger atmaintenance when refrigerant is injected to the unit or isdischarged for repair. Pipe freezing is likely to happen any timewhen the pressure of refrigerant is below 0.4Mpa. Therefore, thewater in the heat exchanger must be kept flowing or be thoroughlydischarged.

3.8 Power Failure Memory Function
3.9 Parallel Function of Wired Controller1) A maximum of 16 wired controllers can be
connected in parallel, and the address can be set in the range of 0 to 15.
2) After wired controllers are connected inparallel, wired controllers with the sameaddress are not allowed on the bus;otherwise a communication failure will occur.
3) After multiple wired controllers are connected in parallel, data is shared among them, e.g.,the power-on/off function, data settings (such as the water temperature and hysteresis) and other parameters will be kept consistent(note: The mode, temperature, andhysteresis settings can be shared only when the system is powered on).
4) Start point of data sharing: After the power-on/off button is pressed, data can be shared during parameter adjustment. The "OK" button must be pressed after parameters are adjusted, and the finally adjusted values will be shared.
5) Since the bus is processed in the polling mode, the data of the wired controller with the minimum number is valid if multiple wired controllers are operated at the same time in the same bus cycle (4s). Avoid the above situation during operation.
6) After any of parallel wired controllers has been reset, the address of this wired controller is 0 by default.
3.10 Upper Computer Communication Function (Reserved)
1) The home page displays the content below during communication with the upper computer: Communication between the wired controller and the upper computer.
2) If the outdoor main control board is in the remote ON/OFF control mode and the wired controller sends an alarm, the current alarm page displays: Remote ON/OFF Control Mode. In this case, the network control of upper computer is invalid, and the wired controller can query the system status only and cannot send out control information.
The power supply to the system fails unexpect-edly during operation. When the system is powered on again, the wired controller continues to operate according to the status before the last power failure, including the power-on/off status, mode, set temperature, failure, protection, wired controller address, timer, hysteresis, etc. However, the memorized content must be the content set at least 7s before the power failure.
