Loss-of-charge/Low-pressure switch.7b. High-pressure switch.7c. Control board diagnostics and fault code display.7d. Safety lockouts send a 24 volt signal to the control board's "X" terminal, allowing notification to the user via the thermostat fault light (if present).7e. Control board shall retain last 5 fault codes in non- volatile memory, which will not be lost in the event of a power loss. An LED (light-emitting diode) indicator flashes a fault code that indicates which safety switch has tripped.7Physical Data9YH-07 Thru -20 and YJ-10 Thru -20 Physical Data9PH-07 Thru -20 and PJ-15 Thru -20 Physical Data10Physical Data Indoor Unit11Unit Limitations12Condenser Unit limitations12Air Handling Unit Limitations13Cooling and Heating Ratings14Cooling And Heating Rating14Capacity Performance15Condenser Only Ratings45PH-07 / NH-07 Cooling Capacities46PH-10 / NH-1048PH-07 / NH-0758PH-10 / NH-1058PH-15 / NH-1559PJ-15 / NJ-1559PH-20 / NH-2060PJ-20 / NJ-2060Airflow Performance61NH-07 Upflow61NH-07 Horizontal61NH/NJ-10 Upflow62NH/NJ-10 Horizontal62NH/NJ-15 Upflow63NH/NJ-15 Horizontal63J64NH/NJ-20 Upflow64NH/NJ-20 Horizontal64RPM Selection65Additional Static Resistance66Altitude/Temperature Correction Factors68Figure 1: Altitude/Temperature Correction Factors681. Determine Upflow or Horizontal supply duct Application.692. Determine desired airflow.693. Calculate or measure the amount of external static pressure.694. Using the operating point, determined from steps 1, 2 & 3, locate this point on the appropriate supply air blower performance table. (Linear interpolation may be necessary.)695. Noting the RPM and BHP from step 4, locate the appropriate motor and/or drive on the RPM selection table.696. Review the BHP compared to the motor options available. Select the appropriate motor and, or drive.697. Review the RPM range for the motor options available. Select the appropriate drive if multiple drives are available for the chosen motor.698. Determine turns open to obtain the desired operation point.691. 3250 CFM692. 1.4 iwg693. Using the supply air blower performance table below, the following data point was located: 1100 RPM & 1.8 BHP.694. Using the RPM selection table below, Model X is found.695. 1.8 BHP exceeds the maximum continuous BHP rating of the 1.5 HP motor. The 2 HP motor is required.696. 1100 RPM is within the range of the 2 HP drives.697. Using the 2 HP motor and drive, 1 turn open will achieve 1128 RPM.69Example Supply Air Blower Performance69RPM Selection69Sound Performance70Outdoor Sound Power Levels (dB), 60 Hz70Electrical Data71Electrical Data - Outdoor Unit - AC Without Powered Convenience Outlet71Electrical Data - Outdoor Unit - AC With Powered Convenience Outlet72Electrical Data - Outdoor Unit - HP Without Powered Convenience Outlet73Electrical Data - Outdoor Unit - HP With Powered Convenience Outlet73Typical Wiring Diagrams77Weights And Dimensions88Corner Weights & Center of Gravity AC/HP Units88Unit Dimensions PH-07, PH-10, YH-07, YH/YJ-10, YH/YJ-1289Unit Dimensions89Unit Dimensions PH/PJ-15, PH/PJ-20, YH/YJ-15, YH/YJ-2090Unit Dimensions91UNIT CLEARANCES91Piping And Electrical Connection Sizes (Inches)91Corner Weights & Center of Gravity NH/NJ Units92Unit Dimensions NH-07 / NH/NJ-10 and NJ-1093Unit Dimensions NH/NJ-1594Unit Dimensions NH/NJ-2095pIPING, ELECTRICAL AND DUCT OPENING CONNECTION SIZES96Minimum Clearances96Typical Suspension of AHU’s From Ceiling97Typical Field Wiring Diagram - NH-07 Unit98Typical Field Wiring Diagram - NH/NJ-10 Thru NH/NJ-20 Unit99NH/NJ-10 Thru NH/NJ-20 Liquid Line Solenoid Wiring99Dimensioni: 6,56 MBPagine: 100Language: EnglishApri il manuale
