Installation &
Operating Instructions
10
Start-Up
1. Locate jobsite drinking water supply.
2. Before window cleaning can begin, the system must be connected to a drinking
water supply. If well water system is the source, it is recommended that a
water quality analysis be performed prior to application.
3. Unger recommends testing the water supply for TDS (total dissolved solids)
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
TM
Resin Bag(s) are properly
installed, with zip-tie facing up.
a. NOTE: Unger does not recommend the use of bulk resin with
nLite HydroPower systems. The use of bulk resin, with its widely
varying properties, may cause damage to the system due to excessive
expansion when water is introduced. Overfilling the systems with
too much resin will also cause damage.
b. Unger’s pre-measured QuickChange Resin Bags are designed to
allow a controlled resin expansion within a designed safety limit.
5. Set up system in upright position. Choose a stable onsite location; best to
locate near work area.
6. Connect hoses to system (drinking water and waterfed wash pole tubing).
Bottom connection is for drinking water supply, top connection is for waterfed
wash pole tubing.
7. Quick connect fittings are supplied with the HydroPower system.
Install quick connect fitting adapter (shipped with unit) to waterfed
wash pole tubing if necessary.
8. Ensure all waterfed wash pole on/off valves are in “OPEN” position.
9. Turn feed water supply “ON” slowly.
10. Inspect system as it pressurizes and begins producing “PureWater.”
Keep discharge line open and hold down yellow FastLock
TM
opening lever to
remove trapped air from system. Use only with drinking water.
11. Turn on TDS meter and inspect “PureWater” quality. A reading of ‘0.00’ is best
and indicates the system is running properly (product water contains zero
parts per million total dissolved solids). Unger recommends changing resin
bags when TDS levels reach 10 ppm.
12. Adjust flow at waterfed wash pole brush head by:
a. On/off valve at base of unit or
b. Waterfed wash pole control (on/off) valve.
13. You are ready to start cleaning.
