Select and prepare an installation siteDocuTech 61xx Installation Planning Guide 4-19Calculate the change in heat loadUse the following table to calculate the change in heat load tothe room. Proceed to the next section to calculate the resultingchange in room temperature.Calculate the change in room temperatureUse the following table to calculate the change in roomtemperature.• Use step 7 if the DocuTech is replacing a currently operatingsystem.• Use step 8 if the DocuTech is a new addition to the room.Table 4-9. Calculating the heat load4. Heat output from the system in run mode in BTU per hr.NOTE: Identify the appropriate heat output for the system from the tableHeat dissipation for the DocuTech printers and devices.4. Heat output______ BTU perhr5. Heat output, in run mode, of the system that is to be removed.NOTE: The table Copier heat output lists the heat output for a number ofcopiers. If no system is being removed, enter zero (0) and proceed to step 8,using the BTU per hr from step 4.5. Heat output______ BTU perhr6. Calculate the change in heat load to the room. Subtract the system heatoutput in step 5 from the heat output in step 4.NOTE: If this number is less than 2000 BTU per hr, no additional heatmanagement actions should be required. If this number is 2000 BTU per hr ormore, proceed to step 7.6. Change in heat load______BTU per hrTable 4-10. Calculate the room temperature7a. Take the change in heat load from step 6 and refer to the figure“Room temperature change” to determine the change in roomtemperature when the DocuTech is substituted for a currentlyoperating system. If the value from step 6 exceeds 16,000 BTU perhr, refer to the figure “Room temperature change (system replaced)”.The figures are used to locate the appropriate change in room BTUper hr. Refer to the appropriate room airflow rate. Then, review thechange that can be expected.7b. Take the maximum room temperature in step 2 and add thechange in room temperature from 7a. Compare the result with themaximum acceptable room temperature from step 3.NOTE: If this temperature change causes the room temperature toexceed the maximum acceptable room temperature, refer to the heatmanagement alternatives.7a. Change in roomtemperature _____ ° F or ° C7b. Maximum temperatureplus change _____ ° F or ° C
