Why the unit is displaying “TANK”?
This indicates the tank is missing from the unit. On the new control boards when the drain tank is full, “TANK FL” LED flashes on the display. As soon as you remove the tank from the unit, the display will switch to “TANK”. After emptying the tank, put it back into the unit and press ON/OFF button. “TANK” will go away. If conditions persist after the above actions have been taken, turn the unit off, disconnect the power and contact your MovinCool reseller or a qualified technician.
