Assembly / Disassembly

 

7.1.  TRP air spray gun atomizing head

 

• Remove the four screws from each atomizing head on the manifold.
• Pull the TRP along the direction of the axis in order to separate it from the manifold.
• For instructions on removing and reassembling the TRP atomizing heads, the nozzle or the air cap,

(

see RT Nr 7005

).

• Proceed in reverse order for the reassembly

 

WARNING :  When reassembling the TRP atomizing head on the upper support, coat the HV well
with dielectric grease.

7.2.  Manifold block

 

• Remove the TRP 500 head(s)..
• Remove the four screws from the HV unit cover.
• Remove the two connections from the rear of the cover then slide the coupling and the gland onto

the cable and the grounding cable.

• Slide open the cover in order to gain access to the HV unit.
• Disconnect the HV unit.
• Remove the High Voltage connection from the Manifold.
• Disconnect the hoses.
• Check the condition of the different components (seals, coupling, micro-valve, resistor, spring) on

the manifold. Replace them if necessary.

• Proceed in reverse order for the reassembly

 

WARNING :  When reassembling the HV unit and the TRP air spray gun, coat the two HV wells on
the manifold with dielectric grease.

 

7.2.1.  Micro-valve
For the micro-valve disassembly or the reassembly , 

see RT Nr 6021
