Installation recommendations
Cartridges should be as tight as possible.
When preparing to drill holes where the cartridge will be located, consider the following factors:
- The inside of the bore should be uniform, without scratches or different diameters, however small, it is recommended to finish it with a reamer.
- Heat rises.
- Dissipation is higher at the ends and heat will be concentrated in the center.
- Choose stock cartridges between 8 to 11 W/cm2.
- Try to have the drill with an outlet, in order to have an easier disassembly.
- The connections must never be inside the borehole, as there is a risk of crossover or burning.
- The connections must be protected to prevent liquids, plastics, gases, etc. from falling out.
- It is advisable to incorporate probes that should be at a maximum distance of 15 mm from the cartridge, connected to a temperature regulator.
- The cartridges must have a minimum cartridge spacing of 3 times the cartridge diameter.
Extraction
If possible, a hole should be drilled at the opposite end of the connections, in order to be able to extract the cartridge more easily.
