5 OPERATION (CONT.)
5.3.2 Hose Temperature Controller
Temperature graduations on hose controller reflect approximate hose temperature.
1. Measure inside hose temperature with a pyrometer and bead probe. Hose temperature should be the minimum
temperature required for application to prevent degradation of material in the hose and maximize hose life.
2. Open front control panel.
3. To raise hose temperature, turn adjustment shaft [2] clockwise with screwdriver to desired temperature on dial.
See illustration below.
4. To lower hose temperature, turn adjustment shaft [2] counterclockwise with screwdriver to desired temperature on dial.
5. Refer to Temperature Check in Maintenance section of the handgun manual
.
5.3.3 Adhesive Flow Adjustment
CAUTION:
For maximum performance and motor life, do not allow pump motor to stall. A prolonged stall condition
will cause motor to go into thermal overload.
Flow Control Valve
An adjustable pressure regulating device is mounted on the pump under the melt unit chassis.
1. Adjust adhesive flow with flow control knob [1] on right side of melt unit.
2. To increase pressure and adhesive flow, turn knob [1] clockwise.
3. To decrease pressure and adhesive flow, turn knob [1] counterclockwise.
4. To achieve minimum pressure and lowest flow rate suitable for application, turn knob fully counterclockwise. Gradually
turn clockwise until desired pressure and flow rate is reached.

5.3 Adjustments
5.3.1 Tank Temperature Controller
1.
To prevent hot melt degradation, set melt tank temperature to
the minimum temperature specified by hot melt manufacturer.
2.
Open front control panel.
3.
To raise melt tank temperature, turn tank temperature
controller adjustment shaft [1] clockwise with screwdriver. See
illustration below.
4.
To lower melt tank temperature, turn adjustment shaft [1]
counter-clockwise with screwdriver. The melt tank
temperature controller range is 260 °C (500 °F) for one 320°
rotation of the adjustment shaft.
5.
Allow melt tank temperature to stabilize 30 minutes before
adjusting further.
6.
Verify temperature on tank thermometer.
5.3.2 Hose Temperature Controller
Temperature graduations on hose controller reflect approximate
hose temperature.
1.
Measure inside hose temperature with a pyrometer and bead
probe. Hose temperature should be the minimum temperature
required for application to prevent degradation of material in
the hose and maximize hose life.
2.
Open front control panel.
3.
To raise hose temperature, turn adjustment shaft [2]
clockwise with screwdriver to desired temperature on dial.
See illustration below.
4.
To lower hose temperature, turn adjustment shaft [2]
counterclockwise with screwdriver to desired temperature on
dial.
5.
Refer to Temperature Check in Maintenance section of the
handgun manual.

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.
