!!! WARNING !!! Stainless Steel barrel has very thin walls. Note that there are 2 parts of the barrel that are grooved for wrenches. When tightening, always tighten the part of the barrel that is closest to the other wrench (on the nozzle or heatsink)! Use properly sized wrenches - 8mm and 12mm! Results are not quaranteed with an improper assembly. !!! WARNING !!!
Assembling the heater part
This is just like in the v3.0.1 assembly manual.
((If you are interested you can read the whole v3.0.1 manual by clicking here, for v4 assembly you only need the specific chapters linked below))

Assembling the top part
Screwing the nozzle and SS part together
Assembling the heatsink
You screw the heatsink onto the stainless steel part with hand *only*!
If you tighten it with two wrenches, you will destroy the part!
If you tighten it with two hands you may destroy the part!
Just screw it using two fingers, and DON'T force it. Please. Pretty please.
((Please note the heatsink orientation.
The bigger diameter (where the fins are) meets with the SS barrel.
Just like on the above picture.))
Applying PTFE strip to the nozzle
To prevent bonding the heaterblock (aluminium) to the nozzle (aluminium) at high temperature we apply ptfe strip around the nozzle, one layer is enough, its only there to prevent direct alu-alu contact (aluminium bonding).
Its easy to remove the surplus ptfe strip, but you DONT NEED to!
It actually help to keep clean the nozzle from the plastic.
Mounting on the machine
The final assembly
The best is control the fan from gcode,
snippet of slic3r's config.ini:
start_gcode = G28 ; home all axes\nM106 S150 ; Fan on
For PLA you definietly need a fan, for
abs you are advised to have one.
You may or may not require depending on
speed, abs manufacturer. However the
print may require slight air movement to solidify
the layers (especially for thin walls).
