Very important

The cartridges must be adjusted as much as possible.

When a hole has to be drilled for the housing of the cartridge, the following factors should be noted:

The inside of the drilled hole must be uniform, without gralings, nor different diameters however small they might be. Finishing off with a reamer is recommended.
The heat rises.
The distribution is greater at the ends and the heat is concentrated in the middle.
Choosing cartridges from stock: comprising 8 to 11 wcm2.
Ensure that the drille hole has an outlet as to make removal easierl.
The conexions must never be inside the drilled hole, as there is the risk of crossing and burning.
The conexión must be protected to prevent possible spilling of fluids and the entry of plastic, gases, etc..
The microporation of a sounding is recommended and must have a maximum distance of 15mm from the cartridge and be conected to a temperature regulator.
There must be a minimun space of 3 diameters between the cartridges.

Extraction

As far as a hole must be drilled at one end of the conexion so that the cartridge may be expanded more easily. The most suitable paste can be found on the market for easier removal and best conductivity (the paste must not be in contact with the conexions).
