Installation and Use Manual Please read this manual carefully before using 18 A. Execute the startup and shutdown sequence according to the prescribed procedure every day. B. Record unit operating parameters at certain intervals. C. Check whether the pressure of the unit is within the normal range through the pressure gauge display on the unit. D. Check whether the appearance of the unit is intact, the surrounding environment is clean and dry, and the ventilation is good, and the components (water pump, compressor, etc.) operate normally. E. Attention should be paid to any shutdown failure and the reasons should be analyzed. Before notifying the company for processing, analysis in conjunction with the troubleshooting help of this manual may help resolve the problem. Scheduled maintenance Caution: In order to prevent casualties due to contact with moving parts or contact with live parts, disconnect the main power supply and hang a clear no-closing sign at the switch position before maintenance inspection! Periodic maintenance includes weekly, monthly, quarterly, and annual maintenance. According to the following contents, customers develop a scientific regular maintenance plan and carefully implement it, which can play a very important role in preventing problems. 1 Introduction Dear users: Thank you very much for choosing our energy saving products!We will be happy to serve you! Please read the instructions carefully before installing and using the product. Otherwise, the equipment may be damaged or the operator may be injured or injured. Installation and maintenance work. It must be operated by professional and technical personnel who have rich experience in installation and maintenance of this model. In case of property damage or casualties caused by violation of this requirement, our company. Will not accept any liability. In order for you to enjoy the service within the warranty period, please strictly follow the requirements of this manual when using the heat pump unit: when reading this manual, if you need technical advice, please contact the company or local agent. 17 6.1 Routine Maintenance This section describes the preventive maintenance and breakdown repair of the unit. Correct maintenance and timely maintenance are conducive to ensuring that the unit is always in the best condition, maintaining the highest efficiency, and extending the life of the unit. Maintenance refers to the preventive maintenance of the unit, and repair refers to the repair of the faulty unit. You are advised to formulate equipment maintenance regulations according to the requirements in this section, and appoint qualified equipment management engineers and dedicated unit operators to perform routine and periodic maintenance. Caution: Unit repairs resulting from incorrect maintenance during the unit warranty period will result in additional costs for the user. The most basic work of unit maintenance and maintenance is to record the operating parameters of the unit at an appropriate time interval every day (such as one hour) and fill in the unit operating parameter table. The true and complete operation parameter record helps to analyze the possible development trend of the unit operation, and helps to timely discover and predict the problems that may occur in the unit, so as to prevent them from happening. For example, through the analysis and comparison of the operation records of one month, it may be found that the difference between the coil temperature of the unit and the ambient temperature has a trend of increasing. This trend indicates that the fins of the unit have scale or dirty blockage, or the ventilation is poor, and personnel should be arranged to check and maintain in time. Note: It is very useful to keep a record of the parameters of the normal operation of the unit during commissioning. This record can be used as a benchmark to compare with subsequent operation records to find the trend of the problem. 6.2 Maintenance 2 Notice A. When installing the air source pool unit, please check whether the specifications and capacity of the power supply meet the requirements of the pool machine according to the nameplate of the unit. B. The power supply of the air source pool unit must be connected with a leakage protection switch, and the leakage protection switch capacity should be greater than the maximum electricity flow of the air source heat pump unit. C. The air source pool unit must have good grounding (grounding resistance ≤0.1Ω) and reliable lightning protection. D. The air source pool unit must be installed in an outdoor ventilated, easy to install and maintain the site. E. The air source pool unit will produce condensate water during operation, drainage pipes and exhaust valves should be designed and installed to ensure that the condensate is discharged in time. F. The air source pool unit must be installed before the water inlet filter, and please remove the air in the tube before use. G. The air source pool machine product is a pressure unit with strong air tightness, which needs to be careful in the process of transportation and hoisting, and can not roll, collide, shake and stack. 16 6. Maintenance and maintenance 3 H. For your safety, do not modify the air source heat pump unit. I. It is strictly prohibited to insert any tools or hard objects into the air source pool unit, so as not to damage the unit or cause accidents due to collision with the wind blade or evaporator. J. Do not use the air source pool unit in the state of removing the barrier or sheet metal and other protective devices, so as to avoid accidents or unit failures. K. When the unit is flooded, please contact the factory or local dealers immediately, must be checked by technicians before reuse the pool unit. L. Personnel without professional qualifications shall not adjust the switches, valves, controllers and other components inside the unit. 1. Product introduction 1.1 Unit Features A.
