Terminating Operation

The button can be used to access the STANDBY screen, which stops the pump and
Standby
halts temperature control operations of the MCH. The mains power switch may be turned
off at any time to completely terminate MCH operation. The set temperature and other
operator-selectable settings are retained in the device's memory.
Turning off the mains power switch isolates both poles (line and neutral) simultaneously
from the supply mains. This may also be accomplished by unplugging the MCH power cord
from the wall outlet.

Current Test

Using a calibrated electrical safety analyzer, measure electrical leakage current of the MCH
unit under the following conditions: power on and off, polarity normal and reverse, unit
grounded and ungrounded. The leakage current should be less than 100μA under all
conditions. If a unit has leakage current that exceeds 100μA or has a significant increase
in leakage current, the cause should be investigated. Refer to Underwriter's Laboratory or
IEC Standards to obtain the current and correct procedures for leakage current
measurement.

Initial Cleaning and Disinfection

To prepare the MCH for storage or initial use, perform the Quarterly Maintenance
Procedure, which may be found in the Maintenance section of this manual.
