CONTENTS SAFETY CONSIDERATIONSInstallation, Start-Up,and Service Instructions AQUAZONEINSTALLATION GENERALSTORAGE - If the equipment is not needed immediately at the jobsite, it should be left in its shipping carton and stored in a clean, dry area of the building or in a warehouse. Units must be stored in an upright position at all times. If carton stacking is necessary, stack units a maximum of 3 high. Do not remove any equipment from its shipping package until it is needed for installation UNIT 50RHC,RVC UNIT 50RHR,RVR Fig. 1 - 50RHC Dimensional Data Fig. 2 - 50RHR Dimensional Data LEFT RETURNRIGHT RETURN Water Unit Hanger DetailFig. 3 - 50RHS Dimensional Data UNIT HANGER ISOLATION DETAIL Fig. 5 - 50RVC Dimensional Data AIRFLOW CONFIGURATIONCode ReturnFig. 6 - 50RVR Dimensional Data Fig. 7 - 50RVS Dimensional Data a50-8169Fig. 8 - 50RDS Dimensional Data ht Return/Bottom DischargeReturn/Bottom Discharge Isometric ViewFig. 9 - Typical Vertical Installation Fig. 10 - Typical Downflow Installation50RVC,RVR,RVS Units 50RDS UnitsStep 4 - Mounting the Unit Factory InstalledFig. 12 - Conversion Right Return Side Discharge to Back DischargeStep 6 - Condensate Drain Fig. 15 - Horizontal Unit PitchFig. 16 - Trap Condensate Drain Fig. 17 - Vertical Condensate ConnectionFig. 18 - Typical Ground-WaterPiping Installation Table 4 - Water Quality GuidelinesStep 8 - Field Power Supply Wiring Step 9 - Field Control Wiringa50-8160 a50-8161 a50-8153 a50-8154 Line Voltage Power Connection Fig. 24 - Low Voltage Field WiringFig. 26 - Typical D Control Accessory Wiring a50-8162Table 5 - 50RHC,RVC Electrical Data Table 6 - 50RHR,RVR Electrical Data PRE-START-UP Table 7 - 50RDS, RHS, RVS Electrical DataCONNECT THE BLUE WIRE TO H FOR HIGH SPEED FAN MEDIUM FACTORY SETTING H M L FAN MOTORM FOR MEDIUM SPEED FAN L FOR LOW SPEED FAN BLU Fig. 27 - 50RHC,RVC Blower Speed SelectionTable 9 - 50RHC,RVC Blower Performance Table 11 - 50RVC Blower Performance with Wet Coil Table 12 - 50RHS,RVS,RDS Blower PerformanceC Control Jumper Settings See Fig D Control Jumper Settings See FigFIELD SELECTABLE INPUTS Table 13 - 50RHS, RVS Blower Performance with HWRTable 14 - DIP Switch Block S2 Accessory 1 Relay OptionsTable 15 - DIP Switch Block S2 Accessory 2 Relay OptionsD Control Accessory Relay Configurations START-UPFig. 28 - HWR Schematic Table 17 - HWR Operating ModesOperating Limits Unit Start-UpCooling ModeTable 18 - Operating Limits - 50RHC,RVC Units Table 20 - Water Temperature ChangeUnit Start-UpHeating Mode Table 22 - 50RHR,RVR Coaxial Water Pressure Drop Table 23 - 50RHS,RVS,RDS CoaxialWater Pressure Drop Table 24 - 50RHC,RVC Coaxial Water Pressure DropOPERATION Units with Aquazone Complete C ControlUnits with Aquazone Deluxe D Control Table 25 - Approximate Fluid Volume galUnits with HWR Option SYSTEM TESTStatus and Alarm Relay Operations Fault DescriptionsSERVICE Aquazone Deluxe D Control LED IndicaFig. 29 - Gravity Flow Method Fig. 30 - Forced Circulation MethodTROUBLESHOOTING Fig. 31 and 32, and Table Refrigerant ChargingAir Coil Fan Motor Removal Fig. 31 - Thermistor Nominal ResistanceTable 30 - Troubleshooting Table 30 - Troubleshooting cont II.START-UP 50RHC,RVC,RHR,RHS,RVR,RVS,RDS START-UPCHECKLISTI.PRE-START-UP HEATING CYCLE ANALYSIS COOLING CYCLE ANALYSISFLOW RATE GPM TEMP.
