Chemical dosing System
Note: always ensure that the waste-water tank is empty before lifting.
The TTV-4555 scrubber dryer has an optional automatic chemical-dosing system.
Simply ll the 5 litre chemical dosing bottle and the machine will deliver the correct mix ratio as set by the operator,
using the setting on the control panel (see page 15) depending on the oor and cleaning conditions.
To ll the chemical-dosing bottle, rst make sure the top waste tank is fully drained then, lift up the waste-water tank
(Fig 23), unscrew the bottle cap then remove the dosing bottle, (Fig 24) and ll with appropriate cleaning chemical.
Ret dosing bottle (Fig 25) and replace bottle cap, and carefully lower waste-water tank.

The machine is now ready to be moved to the cleaning site.
Before performing the cleaning operation, place-out appropriate warning signs and sweep or dust-mop the oor
