The chiller model andserial numbers tue printed on the chiller nameplate located onan exterior corner post. The proper software is factory-installedby Carrier in the replacement module. When ordering areplacement chiller visual control (ICVC) module, specify thecomplete replacement part number, lilll chiller model numbekand chiller serial numbel: The installer must configure the newmodule to the original chiller data. Follow the proceduresdescribed in the Software Configuration section on page 61.Electrical shock can cause pel,sonal injm 7. Disconnect allelectrical power before servicing.INSTALLATION1. Verify the existing ICVC module is defective by using theprocedure described in the Troubleshooting Guidesection, page 79, and the Control Modules section,page 97. Do not select the ATTACH TO NETWORKDEVICE table if the [CVC indicates a communicationfailure.2. Data regarding the ICVC configuration should have beenrecorded and saved. This data must be reconfigured intothe new ICVC. If this data is not available, follow theprocedures described in the Software Configurationsection. If the module to be replaced is functional, config-urations may also be copied manually. The &{ta sheets onpages CL-3 and CL-II _u'e provided for this purpose.Default values are shown so that only deviations fromthese need to be recorded.3.4.5.6.7.8.If a CCN Building Supervisor or Service Tool is avail-able, the module configuration should have already beenuploaded into memory. When the new module isinstalled, the configuration can be downloaded from thecomputecAny communication wires from other chillers or CCNmodules should be disconnected to prevent the newICVC module from uploading incorrect run hours intomemw 7.Record wdues for the TOTAL COMPRESSOR STARTS,SERVICE ONTIME and the COMPRESSOR ONTIMEfrom the MAINSTAT screen on the ICVC.Power off the controls.Remove the old ICVC.Install the new ICVC module.
