8.5 Hose Manifold Filter Block Replacement or Cleaning
The hose manifold filter block is an optional component that is
required when a pump filter is used.
1. If possible, pump out all adhesive in melt unit before
disconnecting power. If not possible, disconnect power and
allow hot melt in tank to solidify.
2. Switch on system power for 5 minutes to warm fittings.
3. Switch off system power and disconnect electrical power at
external source.
4. Disconnect hose electrical connector and tilt melt unit
backwards. Support the melt unit with block on back of
housing so hot melt does not spill. Do not turn melt unit
upside down.
5. Per illustration below, loosen JIC fittings [5] and remove
hose(s) from fitting(s) [6] on hose manifold [3].
6. Remove screws [4] from hose manifold filter block [3].
7. Ease hose manifold [3] from flow control block [1]. Two
screws remain (3 for reverse mounting) holding flow control
block [1] and pump to tank base plate.
8. Clean hose manifold [3] thoroughly, especially flow control
block mating surface, or replace with a spare hose manifold.
9. Refit hose manifold [3] with hardware. After lubricating with
a silicone-based grease such as DC 5, replace o-rings [2].
10. Switch on system power, and allow melt unit to reach
operating temperature.
11. Reconnect hose as specified in Hose Replacement.
