7 UNIT IDENTIFICATION. CORRECT INSTALLATION. PROPER OPERATION Each COMPRESSOR unit has two identifica tion data plates. The REGULAR, SYSTEMATIC PLANNED MAIN TENANCE unit data plate containing unit model, serial number and Frick sales order number is mount ed on the control panel support To ensure correct installation and application, the equipment bracket. The COMPRESSOR data plate containing compres sor must be properly selected and connected to a properly de- model and serial number is mounted on the COMPRESSOR body. signed and installed system. The Engineering plans, piping layouts, etc. must be detailed in accordance with the best practices and local codes, such as those outlined in ASHRAE.

8 NOTICE. literature. When inquiring about the COMPRESSOR or unit, or order- ing repair parts, provide the MODEL, SERIAL, and FRICK. A refrigeration COMPRESSOR is a VAPOR PUMP. To be certain SALES ORDER NUMBERS from these data plates. that it is not being subjected to liquid refrigerant carryover, it is necessary that refriger ant Controls are carefully selected and in good operating condition; the piping is properly sized and traps, if necessary, are correctly arrang ed; the suction line has an accumulator or slugging protec tion; that load surges are known and provisions made for control ; operating cycles and defrosting periods are reason able; oil return is controlled; and that high side condenser UNITS control head pressures and temperatures are within system and compres- sor design limits.

9 It is recommended that the entering vapor temperature to the COMPRESSOR be superheated to 10 F above the refrigerant saturation temperature to ensure that all refrigerant at the COMPRESSOR suction is in the vapor state. DESIGN LIMITATIONS. The COMPRESSOR UNITS are designed for operation within the pressure and temperature limits as shown in Frick Publica- tion UNIT DATA PLATE. SAFETY PRECAUTION DEFINITIONS.
