Grounding
The sprayer must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
1. All models require a grounded outlet for power
connection. Circuit must be 50--60 Hz with an
ampere rating equal to or greater than the sprayer.
See Fig. 1.
2. Do not alter ground prong or use adapter.

3. 120 Vac: A 12 AWG, 3 wires with grounding prong,
300 ft (90 m) extension cord may be used.
220--240 Vac: Use a 3--wire 1.0mm (12 AWG)
(minimum) extension cord up to 90 m long. Long
lengths reduce sprayer performance.
