3SCOH 070 22 E1Technical specificationsMechanical specificationsCompressorVertical hermetic alternative type, mounted on antivibratorysupports, specially designed for heat pump units with oversiz-ing of mechanical components and low consumption motor.The SCOH-070K, 076K, 090K and 120K units have onecompressor, while the SCOH-150K, 180K, 240K and 300Kunits have two compressors.Supplied with a charge of special oil so as to avoid foaming.With oil electric heater.Compressor heaterKeeps the sump oil hot for easy start-up and avoiding oilbeing dragged out of the compressor.Suction accumulatorFitted in the suction tubing of the compressor, it protects samefrom slugging by avoiding oil leaving the compressor.CoilsOf a large surface, made of grooved copper tubing and alu-minium fins. Located inside the cabinet, and thus protectedagainst damage during transportation or installation.Indoor fan (SICH-070 and 076B)A centrifugal fan driven by an independent motor and beltdrive is installed.Indoor fan (SICH-090, 120, 150, 180, 240 and 300B) andoutdoor fan (SCOH-070, 076, 090 and 120K)Two centrifugal fans with a common shaft and belt drive,driven by one single motor and coupled to the single plenum,are installed.Outdoor fan (SCOH-150, 180, 240 and 300K)Two independent centrifugal fans are installed. Each one ofthese is driven by an independent motor and coupled to thesingle plenum.Transmission from the motor to the fan is by belt drive.These fans have sufficient available pressure for the instal-lation of ducts and optional accessories.Cooling circuitMade of welded copper tubing and equipped with accessconnections on the high and low pressure sides.RefrigerantThe SCOH and SICH units are supplied with connectionsready for welding. The refrigerant load should be carried outcompletely on job site. See refrigerant loads in physical datatable. The refrigerant used is R-407C.Electric panelAccesible directly from the outside. Includes connecting strip,protectors, electronic board and probes, power supply con-tactors, operating relay, phase control relay and transformer.In compliance with European regulations currently in force.Phase control relayThe electric panel of the unit introduces a sequence andphase failure detector. In the case of detecting a phasesequence other than R-S-T, or a phase fails once the unit isin operation, this detector, by means of an internal volt-freeNominal capacity:Cooling Heating070K = 18 600 W - 19 000 W076K = 21 000 W - 22 300 W090K = 30 000 W - 33 500 W120K = 33 100 W - 34 400 W150K = 40 000 W - 44 000 W180K = 54 000 W - 56 000 W240K = 74 000 W - 70 000 W300K = 89 000 W - 91 000 WVertical air-air heat pumpwith centrifugal fansVoltage:22 = 230.3.5038 = 400.3.50EditionGeneral informationGeneral descriptionThe SCOH/SICH heat pump models are air-air units with cen-trifugal fans both in the indoor as well as the outdoor units.The SCOH outdoor unit includes compressor, condensingunit, centrifugal fan and controls. The SICH indoor units in-clude evaporating coil, filter and fan. If necessary, they canbe easily modified on job site so as to have a compact unit.The outdoor unit can be installed either outdoors or indoors,as it is protected to withstand outdoor conditions, while thefans are of the centrifugal type and can accept ducts.Supplied complete, factory tested and ready for installationof either interior or duct electric heaters accessories.Designed to achieve considerable savings in energy and along service life.Start-up and automatic regulation of the temperature is car-ried out by means of a 24-volt ambient thermostat.Nomenclature
