Replacing a Heater Cartridge
Use this procedure to replace one or both heater cartridges. The heater
cartridges are housed in bores in the service block.
1. Relieve hydraulic pressure (refer to the Relieving Hydraulic Pressure
procedure in Section3, Installation).
2. Move the applicator circuit breaker to the OFF position, then disconnect
and lock out input electrical power to the applicator (seeFigures7‐1
and7‐2).
3. Disconnect the gun‐to‐hose electrical connection.
CAUTION: Risk of burns. Wear protective gloves when performing this
procedure to reduce the risk of burns from hot melt or equipment.
4. Remove the six screws (three screws per side) from the service block,
then remove the service block cover (seeFigure7‐3).
5. Disconnect the heater cartridge leads from the cordset leads by
loosening the terminal block screws.
NOTE: Make a note of the wire connections for reference when
reconnecting the heater and cordset leads.
6. Remove the heater cartridge.
NOTE: If a heater cartridge does not easily slide out of its bore, remove
the module from service block and then remove the pipe plug at the
opposite end of the heater bore. Insert a rod into the hole and gently tap
on the end of the rod with a hammer. Reassemble the pipe plug and
module after the heater is removed.
7. Remove all leads from the terminal block by loosening the terminal block
screws.
