b. Replacement
1. Switch off system power and disconnect melt unit electrical
power from external source.
2. Never flex a hose when cold. Hoses have a minimum bend
radius of 20.32 cm (8 in.) when hot. Further flexing will cause
permanent damage.
3. Per illustration below, heat hose JIC fittings [5] before
adjusting or damage may result. New or clean hose fittings
may not require heating.
4. Install hoses on melt unit by tilting melt unit back until
underside is accessible. Support melt unit with block on back
of housing so hot melt does not spill. Do not turn melt unit
upside down.
5. Support hose to prevent excessive flexing. Do not support
hose in a way which may add to its thermal insulating
characteristics or overheating will result. Failure to properly
support the hose will result in premature failure.
6. Install hose as follows:
a.
Loosely connect the hose JIC swivel fitting [5] to
fitting [4] on the flow control block or hose manifold [3].
b. Fasten hose support block [1] to chassis.
c.
Tighten JIC swivel fitting [5].
d. Attach hose electrical connector [2].
e.
Tuck electrical connector under melt unit.
f.
Position and support hose before using.
g. After heating, tighten JIC swivel fitting [5].
