• The heating cartridge should be placed in a milled hole with a diameter equal to the nominal diameter of the cartridge, with a tolerance of H7 and a surface roughness of max. 0.8.
• The hole must be at least 2 mm longer than the cartridge body. We recommend using heat transfer paste.
• Incorrect installation of the cartridge can shorten its service life.
• Avoid harsh manipulation with cables - do not pull or bend them sharply. Protect them from dirt, humidity and mechanical strain.
• Only use the supply voltage marked on the cartridge coat, or lower.
• Continuous regulation is more suitable than frequent turning on and off.
• Before first use or after a longer break, it is suitable to dry the cartridge heater at 120 °C for at least 12 hours - either by warming in furnace or by cartridge operation at lower power.
• Store cartridges in warehouses with constant temperature and air humidity.
• Any new use of cartridge heaters in untested conditions should be first consulted with the manufacturer’s technical department.
