3(5) Specifications requirement(6) After the inner part of the copper pipe is cleaned and dried, the inlet and outlet must be sealedtightly by using pipe caps, plugs or adhesive tapes.(1) Pipes that can be used for air conditioner drainage include: water supplying UPVC pipe, PP-Rpipe, PP-C pipe, and HDG steel pipe;(2) All relevant certificates and quality test reports are provided.(3) Requirements for specifications and wall thickness.Water supplying UPVC pipe:Φ1.26in×0.08in, Φ1.57in×0.08in,Φ1.97in×0.10in. HDG steel pipe:Φ0.98in×0.128in, Φ1.26in×0.13in.Φ1.57in×0.14in, Φ1.97in×0.14in.(1) Rubber foam insulation material;(2) Flame retardancy level: B1 or higher;(3) Refractoriness: at least 248°F;(4) The insulation thickness of condensate water pipe: at least 3/8in;(5) When the diameter of copper pipe is equal to or greater than Φ5/8in, the thickness of insulationmaterial should be at least 3/4in; when the diameter of copper pipe is less than5/8in, the thickness of insulation material should be at least 5/8in.NOTICE! For air conditioning units installed in places with strong electromagnetic interference,shielded wire must be used as the communication cables of the IDU and wired controller, and shieldedtwisted pairs must be used as the communication cables between IDUs and between the IDU and ODU.Communication cable selection for ODU and IDUs.R410A Refrigerant SystemOD (in) Wall Thickness (in) ModelΦ1/4 ≥0.03 OΦ3/8 ≥0.03 OΦ1/2 ≥0.03 OΦ5/8 ≥0.04 OΦ3/4 ≥0.04 1/2 H2.2 Condensate Water Pipe2.3 Insulation Material2.4 Communication Cable and Control CableMaterial TypeTotal Length L ofCommunication Cablebetween Indoor UnitandIndoor (Outdoor) UnitWire sizeAWGMaterialStandard RemarksLight/Ordinarypolyvinyl chloridesheathed cord.(60227 IEC 52/60227 IEC 53)L≤3280-5/6ft≥2×AWG18IEC60227-51.
