4. Installation and start-up
4.1 New Machine Set-Up
• Unpack unit:
Inspect nLite ® HydroPower™ DI system and all components. Read warnings and
operating manual.

• Water supply connection
• The inflowing water must comply with the applicable local Drinking Water
Ordinance.
• It must be assured that the connected watertap is equipped with a rebound valve
to prevent water flowing back into drink water line.
• Inflowing water temperature max. 30°C
• Temperature on site 4° to 40°C; not in immediate vicinity of heater.
• Do not install in the immediate vicinity of heat sources or in direct sun.
• Depending on the composition of the raw water, the treated water is more or less
aggressive. Thus, the parts getting in contact with the treated water must be
made of suitable material (e.g. glass, plastic or aluminium). Copper and other
non-ferrous metals are not suitable.
4.2 Start-up
1. Locate jobsite drinking water supply.
2. Before window cleaning can begin, the system must be connected to a drinking water
supply (1). If well water system is source, it is recommended water quality analysis be
performed prior to application.
3. Unger recommends testing the onsite water supply for TDS (total dissolved solids) (5)
prior to working. Higher TDS levels reduce the DI system‘s capacity. Conversely, lower
TDS levels will increase the amount of water the system is able to produce.
4. Inspect system – ensure Unger’s QuickChange™ resin bag(s) (7) are properly
installed, with zip-tie facing up and the sewing in parallel to the vessel ledge.
