22 INSTALLATION MATERIALS SECTIONUnderstand the special requirement (if any) for unit installation before implementation to ensureinstallation quality. Relevant installers must have corresponding engineering construction qualifications.Special type operators involved in the engineering implementation, such as welders, electricians,and refrigeration mechanics must have relevant operating licenses and are accredited with vocationalqualification certification.The materials, equipment and instruments used during air conditioning engineering constructionmust have certifications and test reports. Products with fireproof requirements must be provided withfireproof inspection certificates and must meet national and relevant compulsory standards. Ifenvironmentally-friendly materials are to be used as required by customers, all such materials must meetnational environmental protection requirement and be provided with relevant certificates.(1) Material requirement: Dephosphorization drawing copper pipe for air conditioners;(2) Appearance requirement: The inner and outer surface of pipe should be smooth without pinhole,crack, peeling, blister, inclusion, copper powder, carbon deposition, rust, dirt or severe oxide film, andwithout obvious scratch, pit, spot and other defects.(3) Test report: Certifications and quality test reports must be provided.(4) The tensile strength must be at least 529 lbs.2.1 Installation NoticeNo. Installation Problem Possible Consequence11The ratio of slop forcondensate water pipe isinsufficient or thecondensate water pipe isincorrectly connected.Reverse slop or inconsistent connection of condensate water pipe can hinder thesmooth drainage and cause leakage of the IDU.12 The air channel isimproperly fixed. The air channel will deform; vibration and noise occur during unit operating.13 The guide vane of air channel is not reason-ably manufactured.Uneven air quantity allocation reduces the overall performance of the airconditioner.14The refrigerant pipe or condensate waterpipe does not meet theinsulation requirement.Water can easily condensate and drip to damage the indoor decoration, or eventrigger the protection mode of system due to overheating operation.15 The installation space for IDU is insufficient. Since there is a lack of space for maintenance and checking, indoor decorationmight need to be damaged during such operation.16The IDU or the location of the air outlet orreturn air inlet is not designedreasonably.The air outlet or return air inlet may be short-circuited, thus affecting the airconditioning performance.17 The ODU is improperlyinstalled.The ODU is difficult to be maintained; unit exhaust is not smooth, which reducesthe heat exchanging performance or even prevent the system from normaloperation; in addition, the cold and hot air for heat exchange and the noise mayannoy people in surrounding areas.18 Power cables are incorrectly provided. Unit components may be damaged and potential safety hazard may occur.19Control communication cables areincorrectly provided or improperlyconnected.The normal communication in the system fails or the control over IDUs and ODUsturn in a mess.20 Control communication cables are notproperly protected.The communication cables are short-circuited or disconnected, and the unitcannot be started up due to communication failure.
