It is important that the rinse water going into the instrument is at least 50°C for Crude Fiber and 70°C for detergent fibers. For safety purposes, most hot water heaters are set lower than 70°C. In addition, if there is a substantial distance between the instrument and the hot water heater, the rinse water will, at least initially, be cooler. For these reasons we suggest the purchase of a small hot water heater that can be placed next to the instrument. ANKOM Technology has a small (10 liter) water heater suitable for both the DELTA/DELTAI and the A200/A200I available for purchase (A02).
