Grounding And Electrical Requirements; Thermal Overload - Graco Magnum LTS 15 Repair Manual

Grounding and Electrical Requirements

Grounding and Electrical Requirements
Sprayer must be grounded. Grounding reduces the risk
of static and electric shock by providing an escape wire
for electrical current due to static build up or in the event
of a short circuit.
• The 240 VAC sprayers
require a 220-240 VAC,
50/60 Hz, 10A circuit with a
grounding receptacle.
• Never use an outlet that is
not grounded or an adapter.
• Do not use the sprayer if the electrical cord has a
damaged ground prong.
• Only use an extension cord with an undamaged
3-prong plug.
Recommended extension cords for use with this
sprayer:
• 15 m (49.2 ft) 1.0 mm
• 30 m (98.4 ft) 1.5 mm
• 50 m (164.0 ft) 2.5 mm
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
NOTE: Smaller gauge or longer extension cords may
reduce sprayer performance.

Fluid supply container: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface such as concrete. Do not place the pail on a
nonconductive surface, such as paper or cardboard,
which interrupts grounding continuity.
Grounding the metal pail: connect a ground wire to the
pail by clamping one end to pail and other end to ground
such as a water pipe.
Maintaining grounding continuity: when flushing or
relieving pressure hold metal part of the spray gun firmly
to the side of a grounded metal pail, then trigger the
gun.

Thermal Overload

Motor has a thermal overload switch to shut itself down
if overheated. If unit overheats, allow approximately 45
minutes for unit to cool. Once cool, switch will close and
unit will restart.
To reduce risk of injury from motor starting
unexpectedly when it cools, always turn power
switch OFF if motor shuts down.
