8.Machines are shipped from the factory with the purge level set to accommodate average water conditions. To achieve optimal machine performance, set the purge level to the minimum setting.
Note: While the amount of water purge is adjustable, only those installations with a water supply known to be excellent (very low TDS) should adjust to the minimum setting. See the next page for purge adjustment procedures.
9.After about 6 minutes (first cycle after any restart) the machine will return to a freeze cycle. Note: After the first harvest, the controller will adjusts harvest time as needed to release all ice.
