22Water pipe installation2) Water pipe socket must be connected with a less tightening torque value stated in the below table. If you apply moretorque, it may cause damage to the product.Diameter of water pipe (Outer diameter, mm) 5JHIUFOJOHUPSRVF /tNø10~20 25ø21~30 50ø31~50 100ø51~80 220ø81~115 600❋ /tNLHGtDN3) Use certified parts for water pipe system and the water pressure of the water pipe system connected to outdoor unitmust remain under 1.0 MPa. Use copper or stainless pipe water pipe.4) Water pipes must be equipped with valves and other instrumentations as shown in the diagram. Strainer and flowswitch must be installed within 1~2 m from the entrance pipe of the DVM Hydro unit / Hydro unit HT.- When strainer is not installed, sand, dust or rust debris may cause product breakage.5) Water inlet pipe is located at the bottom part of the heat exchanger and the water outlet pipe is at the top part of theheat exchanger.6) DVM Hydro unit / Hydro unit HT must be installed indoor at room temperature and the water inlet and outlet mustbe insulated with the heat exchanger as shown in the diagram.7) Damp-proof, cold reserving and insulation work must be done thoroughly to prevent condensation from forming onthe surface of the product and drain pipes of indoor/outdoor units. When the necessary work is not done thoroughly,you will waste energy caused by thermal loss and may get property damage during cold seasons when water pipefreezes and bursts. This product will keep the circulation pump to operation in certain interval, even when the poweris off, in order to prevent pipe rupture. Therefore, you must check if the power (220~240 V) is being supplied.8) If you stop the product for long time or in night time, water pipe circuit may freeze naturally when the temperaturearound the DVM Hydro unit / Hydro unit HT is under 0 °C. When water pipe circuit freezes, it will cause damage to theplate type heat exchanger and therefore preventive measure must be taken according to the situation.- Drain remaining water in the water pipe- Install self-regulating heat cable on the water pipes- If the product is installed in a place where surround temperature drops below 0 °C, use anti-freeze accordingly forfreezing point depression.9) Install number of auto air discharge valve at a point where air may remain within the pipe (such as vertical waterpipe). If the air within the pipe is not discharged, it may cause performance decrease or corrosion on the product orpipes.10) Following is the operation range of water.SectionOutlet water temperature (°C) Amount of water (ℓ/min)ADN✴✴✴BDE✴✴AM✴✴✴FNBD✴✴ AM✴✴✴FNBF✴✴ ADN160BDE✴✴AM160FNBD✴✴ADN320BDE✴✴AM320FNBD✴✴ADN500BDE✴✴AM500FNBD✴✴ AM160FNBF✴✴ AM250NBF✴✴StandardconditionCooling 18 - 48 92 150 - -Heating 35 65 23 36Operation range Cooling 5~30 - 24~48 46~92 75~150 - -Heating 20~50 25~80 14~46 14~72f When the amount of cooling water is out of the operation range, stop the DVM Hydro unit / Hydro unit HT and take careof the cause before re-start the operation.f Temperature of discharged water is very high so be careful not to come in contact with the body. Also, cover the externalwater pipe with appropriate insulator for insulation and preventing burns.k}tGokyvGo{ptXYWZ`]]hTXluUGGGYY YWXZTW_TW]GGG㝘㤸G`a[[aY_
