Installation
Installation
To avoid personal injury, be especially careful when
connecting the high pressure material supply system
and always keep clear of the nozzles when test spray-
ing.
Before starting installation of the Graco Switch 3D Gun,
refer to the Description on page 6, and Component
Identification on page 7, in order to be familiar with the
various parts of the Switch 3D Gun.
To ensure trouble free operation of the Switch 3D Gun,
it is important that the unit is properly installed on the
robot. It is important that the function of the Switch 3D
Gun is carefully checked before start up.
The Switch 3D Gun has multiple robot mounting options
which can be purchased separately from Graco inc. See
Switch 3D Gun Mounting Kits Manual, (3A8066) for
instructions and parts for mounting to a specific robot.
For typical installation of a Switch 3D Gun see Switch
3D Gun Installation in this section.
Inspect the Switch 3D Gun for shipping damage. If there
is damage notify the shipping carrier immediately.
Grounding
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
The following grounding instructions are minimum
requirements for a basic Switch 3D gun installation. The
specific system and robot being used may include other
equipment or objects that must be grounded. Check
local codes for detailed grounding instructions.
Switch 3D Gun: Ground through a connection to a
properly grounded material hose and pump.
Pump: See your pump manual.
Material hoses: Use only electrically conductive hoses
with a maximum of 100 ft. (30.5 m) combined hose
length to ensure grounding continuity. Check the
electrical resistance of the material hoses at least once
8
a week. If the total resistance to ground exceeds 25
megohms, replace the hose immediately. Use a meter
that is capable of measuring resistance at this level.
Fluid supply container: Follow local codes.
Solvent pails used when flushing: Follow local codes.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a non-conductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the Switch 3D
Gun firmly to the inside of a grounded metal pail, then
trigger the valves.
