DANGER:
To avoid personal injury, follow all
safety labels. Failure to properly operate and
maintain equipment can lead to serious injury.
•
Wear protective clothing, safety goggles and
safety gloves. Hot melt materials can cause
severe burns resulting in disfigurement or
blindness.
•
Use only manufacturer recommended materials
in this system. Fire, explosion, personal injury,
property and equipment damage can result if
improper or unsafe materials are used.
•
Disconnect electrical power from external
source to melt unit before undertaking
maintenance or troubleshooting. Failure to
disconnect power can result in fatal electrical
shock.
•
Depressurize system before performing any
maintenance to pump, pump filter, flow control
valve or hose. Turn pump switch off and
depress trigger on handgun until there is no
flow. Air trapped in the system or in a
component can form a pressure pocket.
Loosen fittings cautiously. Adhesive under
pressure can cause severe burns and
blindness.
•
Always read the manufacturer’s recommended
use of the material.
5.2 Startup Instructions
1.
Become familiar with Section 5.1, Controls and Indicators.
2.
Install melt unit as specified in Section 4, Installation.
3.
Fill tank with hot melt material.
4.
Turn melt unit on and allow sufficient warmup time for hot
melt material to thoroughly melt.
5.
Align motor on receipt of a new unit or after transportation.
a.
Loosen four screws holding motor pan to side of melt
unit.
b.
Heat melt unit and run motor. This centers the motor.
c.
With motor running, tighten four screws in a crisscross
pattern.
6.
Set hose and tank temperatures to desired settings. Lower
settings increase pot life of the material. Materials degrade
over time due to oxidation.
7.
To prevent motor stalling, adjust flow control valve to the
minimum flow requirement.
