Note:
While operating in the Spray Auto function under
standard conditions, all emulsion passing through the emulsion
pump flows through the spray nozzles. Bypassing emulsion is not
possible unless a control valve for the pumping station
malfunctions or the pump outlet pressure exceeds the pump
bypass set point of 80 psi (5.5 bar), which is about five times the
typical spraying pressure.
Using the spray wand
1.
Select
Pump Function
>
Spray Auto
, and activate the pump.
2.
Use an arc spraying motion to coat the surface until the desired
coverage is reached.
Tip:
If the master spray switch on the pendant is off, there
will be higher pressure to the spray wand because the pump runs
at a fixed speed to build pressure within the spray bars. If the
master spray switch is on, the spray wand will operate at a lower
pressure, and coverage will be below the set amount.
