The following items must be checked at every PM visit:
Water:
Due to the erratic nature of local water utilities, water supplied to Unic equipment must always pass through a treatment system, even if pre-
treated water meets all listed specifications. For testing, water samples must be taken post treatment system and Unic recommends Hach
product #275525. These testing strips are available from
www.hach.com.
TDS (Total Dissolved Solids)
Supply Voltage:
Steam recovery speed and proper functioning of low-voltage circuits are dependent on supply voltage. Always measure supply voltage at
terminal of the machine.
Begin by accessing the terminal through the left side panel. Measurement across terminals ‘N’ and ‘S’ for single-phase network supplies, and
across ‘N’ and ‘R/S/T’ for three-phase network supplies. In addition, ensure phase balance by measuring each phase to ground.
The machine is fitted with a multi-voltage transformer to ensure that the supply to the electronics is stepped-down the correct right voltage.
It is necessary to verify that the transformer bridge is installed in accordance with the previously measured network supply voltage. Remove
machine from network supply if change is necessary.
