HEC-OM-S002 Chapter 4 System Set-up 4.3.2 Filling Bath Liquid Make sure the drain port is plugged. Make sure the strainer is installed correctly. Supply bath liquid slowly. Do not pour bath liquid to the controller. Fill bath liquid up to a maximum level of 30 mm below the top of the bath. In case the liquid level is low, it may have cooling capacity deteriorate because the internal pump may have aeration.
HEC-OM-S002 Chapter 4 System Set-up 4.4 Turning ON power Make sure that Main power switch is OFF. Turn ON the power breaker on primary side (your tool side). Turn ON Main power switch. Controller will indicate the current Bath liquid temperature after approx. 6 sec.
