Louver display “One Hour Only” indicator Indicates the action of the swing louver. Does not appear if the louver is stationary. Displayed if the airflow is set to weak and downward during COOL or DRY mode. (Operation varies according to model.) The indicator goes off after one hour, at which time the airflow direction also changes. Ventilation indicator Appears when the unit is running in Ventilation mode. (Power On indicator) Indicates that the power is on. Caution ● Only the Power display lights when the unit is stopped and power supplied to the unit. ● When power is turned ON for the first time the (Centrally controlled) display appears to go off momentarily but this is not a malfunction. ● “NOT AVAILABLE” is displayed when the Air speed button are pressed.This indicates that this room unit is not equipped with the fan direction adjustment function and the louver function. ● When power is turned ON for the first time, it is normal that “PLEASE WAIT” is displayed on the room temperature indication (For max. 2minutes). Please wait until this “PLEASE WAIT” indication disappear then start the operation. www.ilmalämpöpumput.com 4 05.2.24 8:52 AM Page 5 Mitsubishi ilmalämpöpumput korjaa ja huoltaa: Jäähdytinpalvelu RefGroup Oy (pääkaupunkiseutu) 2 SPECIFICATIONS SLZ-KA35VAL.TH SLZ-KA50VAL.TH SLZ-KA25VAL.TH SLZ-KA35VA.TH SLZ-KA50VA.TH SLZ-KA25VA.TH Function Cooling Cooling Heating Cooling Heating Heating Single phase Single phase Single phase Power supply 230V, 50Hz 230V, 50Hz 230V, 50Hz Capacity Air flow (High/Medium/Low) K /h 660/540/480 600/540/480 660/540/480 Power outlet A 20 10 10 Running current ✽1 A 0.65 0.35 0.40 Power input Rated frequency W 85 75 85 Dew prevention heater (kW) 0.014 0.014 0.014 Power factor ✽1 94 % 97 97 90 93 94 Fan motor current ✽1 A 0.27 0.19 0.26 Model PK6V20-LM PK6V15-LD PK6V20-LL WHT-BLK : 407 BLK-BLU : 86 WHT-BLK : 393 BLK-BLU : 164 WHT-BLK : 325 BLK-BLU : 143 Winding " BLU-YLW : 47 BLU-YLW : 30 BLU-YLW : 47 resistance (at20:) BRN-RED : 309 BRN-RED : 165 BRN-RED : 319 Width mm(in) UNIT : 570(22-7/16) PANEL : 650(25-9/16) Height mm(in) Dimensions UNIT : 208(8-3/16) PANEL : 20(13/16) Depth mm(in) UNIT : 570(22-7/16) PANEL : 650(25-9/16) Weight kg UNIT : 16.5 PANEL : 3 Air direction 4 4 4 Sound level(High/Medium/Low) dB(A) 39/34/30 37/31/28 38/33/29 Fan speed(High/Medium/Low) rpm 710/590/530 650/530/480 690/570/510 Fan speed regulator 3 3 3 Thermistor TH1(at25:) k" 10 10 10 Thermistor TH2(at25:) k" 10 10 10 Thermistor TH5(at25:) k" 10 10 10 Fan motor Electrical data Indoor model Special remarks OC320-1.qxp NOTE : Test conditions are based on ISO 5151 Cooling : Indoor D.B. 27: W.B. 19: Outdoor D.B. 35: W.B. 24: Heating : Indoor D.B. 20: W.B. 15: Outdoor D.B. 7: W.B. 6: Refrigerant piping length (one way): 5m ✽1 Measured under rated operating frequency.
