Anleitung Zusammenfassung
Only the interconnecting liquid and suction lines, sight glasses, control wiring, and the main power wiring are required to complete the installation. Every unit is dehydrated, evacuated, leak tested and pressure tested at 450 psig before being pressurized with a holding charge of refrigerant-22 for shipment and/or storage. To eliminate the costly cabinet deterioration problems usually associated with outdoor equipment, all sheet metal parts are constructed of commercial grade (G90) galvanized steel. After fabrication, each part is thoroughly cleaned to remove any grease or dirt from its surfaces. The parts that will be exposed to the weather are then coated with a “desert sand” powder paint to assure a quality finish for many years. This coating system has passed the 750-hour, salt spray test per ASTM Standard B117. Every unit includes 2 heavy-duty scroll compressors, 2 suction line accumulators, 2 4-way reversing valves with a 24 volt solenoid, 2 outdoor fan motors with inherent protection, and a copper tube/aluminum fin coil that is positioned vertically for better drainage of the water that will condense on it during the heating cycle. All controls are located in the front of the unit and are readily accessible for maintenance, adjustment and service. All wiring (Power and Control) can be made through the front of the unit. REFERENCE This instruction covers the installation and operation of the basic condensing unit. For information on the installation and operation of the matching indoor units, refer to Installation Instruction part no. 035-16626-000 (form 515.41-N4Y). All accessories come with a separate Installation Manual. Refer to Parts Manual for complete listing of replacement parts on this equipment. All forms may be ordered from: Standard Register Norman, OK 73069 Toll Free: Tel. 877-318-9675/Fax. 877-379-7920 INSPECTION They also include 2 filter driers, 2 expansion valves and distributors that are only used during the heating cycle plus a check valve to provide the proper flow of refrigerant through the unit during both the cooling and heating cycles. As soon as a unit is received, it should be inspected for possible damage during transit. If damage is evident, the extent of the damage should be noted on the carrier's freight bill. A separate request for inspection by the carrier's agent should be made in writing. Installer should pay particular attention to the words: NOTE, CAUTION and WARNING. Notes are intended to clarify or make installation easier. Cautions are given to prevent equipment damage. Warnings are given to alert installer that personal injury and/or equipment damage may result if installation procedure is not handled properly. 035-16192-001-A-1001 TABLE OF CONTENTS GENERAL ............................................................................. 1 REFERENCE ............................................................................. 1 INSPECTION ............................................................................. 1 NOMENCLATURE...................................................................... 2 INSTALLATION LIMITATIONS ............................................................................. 3 LOCATION Roof-Top Locations............................................................. 3 Ground Level Locations...................................................... 3 RIGGING AND HANDLING ........................................................ 3 CLEARANCES ........................................................................... 4 COMPRESSOR CRANKCASE HEATER ................................... 4 POWER AND CONTROL WIRING Power Wiring ...................................................................... 4 Control Wiring..................................................................... 4 REFRIGERANT PIPING General Guidelines............................................................. 7 Line Sizing .......................................................................... 7 Service Valves .................................................................... 7 Installation........................................................................... 7 EXTENDING THE SERVICE PORTS......................................... 9 EVACUATING AND CHARGING ................................................ 9 BALANCE POINT SETTING....................................................... 9 ALTERNATE CHARGING METHODS........................................ 10 OPERATION GENERAL ............................................................................. 11 SYSTEM SEQUENCE OF OPERATION Cooling Operation............................................................... 11 Heating Operation............................................................... 12 Defrost Cycle ...................................................................... 12 Operation Below 0°F........................................................... 13 Emergency Heat Operation .............................................
