Safety: the operation of the heat pump is safe and automatic.e. Provide OEM/ODM serviceQ:Why it can work at -25ºC?Because of the Enhanced Vapor Injection (EVI) technology from Copeland compressor, EUROSTARS designed EVI gas piping system and controlling system, make EVI air source heat pump can work stably in the low temperature condition.8.Customer visit us9.Air source heat pump delivery or container loading10.Installation instruction or installation photo, project photosA,Place selection of installation Heat pump1). Heat pump should be installed in alarge space, and have good air flow condition.2). Air inlet and outlet must be aclear road, the distance from barrier to inlet and outlet must be longer than 2m.3). Set drain ditch or drain outlet, so that can drain water easily.4). The installation base or bracket must be firm, make sure heat pump work balancely.5). Make sure heat pump is vertical, can't be slanted.6). Don't install heat pump at the place in where there is plenty of pollutional and corrosive gas or sand or fallen leaves.7). The installation place can't be near inflammable, flammable thing or fire.8). Installation:---The installation base can be concrete construction, or steel bracket, and must use anti-vibration rubber pad, And the surface should be smooth.---The design of installation base can be according to heat pump weight.---The heat pump bottom should be fixed by bolt.B,Pipe connectionThe drain pipe and overflow pipe should be installed near drain ditch or drain outlet, easy to drain, and install drain water valve on drain pipe before magnetic valve there should be service valve on water pipe.If use plastic pipe (such as PPR pipe or ABS pipe), users should consider pipe expand and contract problem between heat pump and water tank.Water supply valve and cut-off valve maybe need insulation (according to local weather condition),avoid frost crack.C,Water pipe system installationWater pipe should be straight, and the arrange should be reasonable, reduce bend as little as possible. Reduce the water pipe resistance.There can't be leaking at any place of pipe.After all equipments and pipes installation finished, users should test water pressure, and drive air out, drain dirty out, make sure water cycle system is clean. After confirm there is not any problem, then insulate all hot water pipes.D,Power supply wiring220V heat pump use single phase power supply, 380V heat pump use three phase power supply, wire line is 3phase 4lines, AB Cconnects live line, Nconnects null line, Econnect earth. Be sure not to connect Nline to live line of power supply.1).When repairing, please turn power supply at "off" side.2).Power supply connecting process:make sure aequipment power supply is cut off before its installation is finished. Install power supply switch at suitable place, Use rubber hole for wiring line in electric box.Power supply demand:220V rated voltage±10%380V rated voltage±10%frequency:50Hz rated frequency±2%3).if power supply fluctuation is out of demand, please don't start your heat pump.
