MHP4-11M-SERIES REFRIGERATION SYSTEM Factory charged with R-410A refrigerant Factory sealed and tested Refer to Unit Electrical and Physical Data tablefor additional detailsElectronic Blower Control Dedicated blower speed taps for continuous fan,cooling, and heating operation are programmedfor optimal airflow and controlled by 24Vthermostat signals Blower speed adjustment is easily accomplishedby speed tap selection Fixed blower delays have been selected toenhance comfort Refer to Blower Performance tables for additionaldetailsIndoor and Outdoor Coils Copper tube with aluminum fin coilsHigh Pressure Switch Shuts off unit if abnormal operating conditionscause the refrigerant discharge pressure to riseabove acceptable levelsOUTDOOR COIL FAN Heavy duty, fully enclosed and weatherproof Aluminum fan bladesLow Pressure Switch Provides loss of charge protection by shuttingoff unit if refrigerant liquid pressure falls belowacceptable levelsCONDENSATE MANAGEMENTPrimary Drain Pan Antimicrobial protection: drain pan is injectedwith an antibacterial agent that destabilizes themembrane of microorganism cells, disruptingthe cellular function of odor-causing mold andbacteria so that they can no longer grow orreproduceReversing Valve Reverses the direction of refrigerant flow withinthe unit’s refrigeration circuit, to change betweencooling and heating operation. Reverses refrigerant flow direction during heatpump defrost cycles to clear outdoor coil of frostbuildup.Overflow Protection Indoor drain pan overflow switch, which monitorsthe condensate level in primary drain pan Prevents units from operating if drain clogs andwater is sensedDefrost Control Factory mounted sensor determines whendefrost cycle starts and ends Anti-short cycle, timed-off control is incorporatedin the control boardSecondary Drain Pan Polypropylene wall sleeve base is specificallydesigned to direct rain water out of the buildingand in the event of any restriction in the primarydrain will act as a redundant overflow protectionTRANSFORMER Rated for 40VA Factory wired for 230/240V power supply, andincludes field selectable terminal for 208V Converts line voltage to 24V for the thermostatand control circuits within the unitOPTIONS & ACCESSORIESSUPPLY AIR BLOWERECM Constant Torque Blower Motor Electrically efficient motor for reduced electricalconsumption Motor provides specified air volume at 0.1 in. - 0.5in. w.c. external static pressure Motor is resiliently mounted for quiet operation Blower assembly is easily removed for servicing Refer to Blower Performance tables for additionaldetailsFACTORY-INSTALLED OPTIONSELECTRIC HEAT Mounted internal to unit cabinet Multiple kW sizes available; must specify theelectric heating element size (3kW to 10kW) Optional two stage electric heat wiring on 7 &10kW. In order to utilize this option, it will requirea thermostat with single stage cooling and twostage heating Compatible with 208V, 230V and 240V Helix wound nichrome heating elements exposeddirectly into the air stream resulting in instantheat transfer and low element temperatures Cutoff limit control provides positive protectionin case of excessive temperatures Refer to Rated Cooling & Heating Performancetable for additional details- Page 4 -
