Page 13: Process Description
4 PROCESS DESCRIPTION This section provides general information regarding the heat disinfection process utilized by Heatsan unit. Operation General philosophy of operation: The unit can be configured to disinfect up to two distribution loops, either individually or together. The user can set for each day of the week which loop is to be disinfected and in what configuration. -
Page 14: Hold Period (Heatsan Operation)
Once the pre-programmed “Heatsan Start” time has been reached the Heatsan will isolate the RO from the distribution loop. The Heatsan will then be automatically connected to the loop using the motorized valves on the associated manifold. The internal pump will circulate the preheated water around the distribution loop(s) to be disinfected. -
