6.2 Tank Screen Inspection
Tank Screen Replacement P/N 986611
A “U” shaped screen is located in the bottom of the melt tank to prevent contaminants from damaging the
adhesive pump assembly. This screen should be inspected and cleaned on a regular basis. It is easiest to do
this when the melt tank is at operating temperature and close to being empty of adhesive.
1. Grasp the screen from the bottom of the melt tank using needle nose pliers. Be very careful not to let
any contaminants on the screen fall back into the melt tank.
2. Clean all debris from the screen using purging compound.
3. Inspect the screen for damage and replace if necessary.
4. Reposition new or clean screen into the bottom of the melt tank assuring it fits snugly between the grids
and over the top of the sump hole outlet to the gear pump.
6.3 Front Panel Fuse Replacement
Fuse Kit Replacement P/N 989360
Before you attempt to change or check the fuses, remove all power from melt unit.
All hoses and other control connected to the unit should be removed from the unit until the cause of the
blown fuse is removed.
The fuse blown should be a good indicator as to where to look for the problem.
1. First remove the control from the melt unit (see manual for details). Note removal of the connector is not
required.
2. The fuses are located on the connector panels and are inserted into small pin holders.
3. After locating fuses use a digital voltmeter (DVM) to locate blown fuse.
4. Use a needle nose pliers to carefully grip and remove the damaged fuse.
5. Replace with new fuse by inserting the fuse firmly back into pin holder.
6. Re-install control panel back into the melt unit and reconnect power to unit.
7. Reconnect the items to the unit and restore power.
