4.4 Hot Melt Supply Hoses
Notice
The hose should not be flexed when cold to avoid damage. The hoses have a minimum bend radius of eight inches
when hot; further flexure will cause permanent damage.
Notice
Hot melt fittings must be heated before loosening or tightening to prevent damage. New and clean supply hose
fittings do not need to be heated.
Notice
Support the hose during dispensing operations to prevent excessive flexure. Failure to properly support the hose will
result in premature failure.
Notice
Ensure that you have access to the adhesive manifold fittings and electrical connectors being careful not to tilt it
beyond the point where adhesive can spill from the melt tank. Never turn the melt unit upside down.
Loosely connect the JIC swivel fitting on the hose to the manifold fitting, and then tighten the JIC swivel fitting
using an 11/16” open-end wrench. Be certain the JIC fitting is securely seated on the manifold fitting otherwise
adhesive will leak once the unit reaches operating temperature.
Properly align the keys of the hose electrical connector to the melt unit connector and securely screw these parts
together.
4.5 Handheld Applicators
The handheld nozzle should never be pointed towards people when the melt unit is powered. Pressures can develop
within the hot melt system causing the adhesive to be projected significant distances. Pointing the handheld
applicator nozzle at someone (including yourself!) presents a potential burn hazard.
The trigger mechanism of the handheld applicator should never be pulled until the entire system is up to operating
temperature. Attempts to retract the trigger before adhesive in the handheld applicator has adequately softened will
result in damage to the needle assembly. This damage is not covered under warranty.
The backside of the handheld applicator grip contains a yellow lever to control pump motor operation. It is
recommended that the front panel of the melt unit be set for cycle operation with pump motor control from the
handheld applicator switch. This will prevent unnecessary wear on the motor and pump mechanisms.
Hot melt fittings must be heated before loosening or tightening to prevent damage. New and clean supply hose
fittings do not need to be heated.
