3.
Turn the HEAT switch (66) to ON. Pump will not
operate until 30 minutes have elapsed, allowing
material to fully heat.
4.
Open the dispense valve over a waste container to
relieve pressure when material heats and expands.
5.
After each of the dispense zones is heated to oper-
ating temperature, wait an additional 30 minutes to
allow the material to heat fully.
6.
Make sure that all material valves are open.
7.
Turn the pump air supply ON and set the regulator
for normal operation.
8.
Dispense material into a waste container. Adjust the
flow rate as needed.
Using Optional 7-Day Timer
The 7-day timer can be set to automatically turn the heat
on to the system. Using the timer requires you to:
•
Create a schedule and program it into the 7-day
timer, located on the electrical control panel. Be
sure to allow at least 30 minutes for the material to
heat up before the supply unit is used. For timer pro-
gramming information, see the electronic control
panel documentation.
•
Perform a nightly procedure to ready the system for
automatic operation.
