Transport, installation and assembly
4.3 Assembly
WARNING
If untrained personnel carry out assembly work, they endanger themselves
and others, as well as risking the operational safety of the machine.
➤
Electrical and electronic parts must be installed exclusively by specialist
personnel with an electrical qualification – all other parts, e.g. the spray
hose or spray gun, must be installed exclusively by trained personnel.
WARNING
During assembly work ignition sources may arise (e.g. due to mechanical
sparks, electrostatic discharge, etc.).
➤
Carry out all assembly work outside of potentially explosive areas.
Prior to start-up, correctly refit any parts or equipment items removed for trans-
port purposes, as required for the intended use.
Prior to assembly work, sure that all compressed air shut-off valves are closed
and that all air pressure regulators have been fully regulated back.
4.3.1 Connect the spray hose and spray gun
WARNING
Parts that are not designed for the maximum permissible operating pressure
of the machine may rupture and cause serious injuries.
➤
Prior to installation check the maximum permissible operating pressure
of the spray hose and the spray gun. The operating pressure must be
greater than or equal to the maximum operating pressure cited on the
type plate.
Connect the spray hose to the material outlet of the static mixer.
Connect the spray hose to the spray gun as described in the operating man-
ual for the spray gun used.
4.3.2 Ground the machine
WARNING
The high flow speeds with the airless spray process can result in an elec-
trostatic charge. Static charges can result in fire and explosions.
➤
Ensure that the machine is grounded outside of EX zones!
➤
Also ground the object that is to be coated.
In order to ground the machine, connect the main ground cable first to clamp 1
of the grounding terminal and then to an electrically conductive object outside
hazardous areas.
