130AWHAir / Water Cycle Heat PumpThis air conditioner adopts the new HFC refrigerant•(R410A) which does not destroy ozone layer.R-410A refrigerant operates at 50%-70% higher pressures•than R-22. Be sure that servicing equipment andreplacement components are designed to operate withR-410A.R-410A refrigerant cylinders have a dip tube which allows•liquid to flow out with the cylinder in a vertical positionwith the valve at the top.R-410A systems should be charged with liquid•refrigerant. Use a commercial type metering device in themanifold hose in order to vaporize the liquid refrigerantbefore it enters in the unit.As for other HFC, R-410A refrigerant is only compatible•with oils recommended by the compressor manufacturer.A vacuum pump is not enough to remove moisture from•oil.Oils absorb moisture rapidly. Do not expose oil to•atmosphere.Never open system to atmosphere while it is under•vacuum.When the system must be opened for service, break•vacuum with dry nitrogen.Do not vent R-410A into the atmosphere.•Use this unit only for factory approved applications.The capacity and unit code are stated on the nameplatedata.R-410A - General infoSITING THE UNITINSTALLATIONR-410A - General info .......................................................... 1Safety procedures ................................................................ 2Dimensions and clearances............................................... 4Technical data ....................................................................... 4Installation ............................................................................. 5Water connections ............................................................... 6Electrical connections......................................................... 8Connection of Auxiliary Accessories .............................. 9System test ............................................................................. 12Unit protection devices ...................................................... 15Maintenace ............................................................................ 15Contents PageWATER CONNECTIONSELECTRICAL CONNECTIONSCONTROL WIRING (Optional)POWER WIRINGFILLING THE SYSTEMFLUSHING WATER AND AIRCHECKING FOR WATER LEAKSCONFIGURING AND CHECKING THE SYSTEMCAUTION:• Do not leave system open to atmosphere any longerthan minimum required for installation.• Oil in the compressor is extremely susceptible tomoisture absorption.MODELS WITH HYDRONICMODULEMODELS WITHOUTHYDRONIC MODULE30AWH004HB 30AWH004XB30AWH006HB 30AWH006XB30AWH008HB 30AWH008XB30AWH012HB 30AWH012XB30AWH015HB 30AWH015XBEnglish
