1. Make sure the hot runner is either installed in the machine or laying on a work bench with
the nozzle tips facing up.
2. Make sure all nozzle tip insulators are clean and in good condition.
CAUTION!
Mechanical hazard – risk of damage to the hot runner. Due to geometric variations between
the gate details and the witness marks left in nozzle tip insulators by the nozzle tips, Husky
does not recommend reusing nozzle tip insulators. Previously used nozzle tip insulators
should always be replaced with new nozzle tip insulators whenever possible.
3. Place a nozzle tip insulator on each nozzle tip. If used nozzle tip insulators are being installed,
make sure they are installed on the same nozzle tip as previously removed and in the same
orientation.
