Liquid Spray System Operating Instructions
1. Read all instructions before operating. Always
wear hand, eye, and skin protection when
working with de-icing chemicals. Make sure
everyone is standing clear of liquid spray system
before operating.
2. Inspect all plumbing for leaks.
3. Open ball valve (#WSE10) at the reservoir.
4. Make sure reservoir has adequate supply
of clean de-icing liquid. Do not operate pump
without liquid.
5. Before turning the cab controller on, turn the
black speed control knob counter clockwise until
it stops to set the pump at the slowest speed.
6. To energize system, turn red power button to
illuminate LCD screen “on” position.
7. Increase pump speed to desired liquid spray
application rate by turning black knob clockwise.
8. If the red low pressure warning light/alarm
comes on, the reservoir is empty or the pump is
off. Do not operate pump without liquid. Note:
Low pressure light and alarm will sound each
time system is started. This is normal and
occurs until sufficient pressure is achieved to
open pressure switch (turning off light/buzzer).

when not in use.
