OPERATION
Daily Start-up Procedures
1. Check the condition of the Hydraulic and Lube System and service as required.
Change the Pump Lube when it shows signs of color change.
NOTE:
The Daily Start-up Procedures
describe normal operation and
assume that all calibrations have
been properly executed.
2. Determine that the supply system is at the proper temperature as recommended by the
chemical system supplier, the individual chemicals are properly mixed within their
drums/day tanks, and the moisture protection system is properly set for operation.
3. Check the inlet screens and service as required.
4. Turn on the Main Air Supply to the Transfer Pumps and drums/day tanks.
5. Open both Iso and Polyol Inlet Supply Valves.
6. If the red Emergency Stop Switch has been activated, reset it by turning the knob
clockwise.
7. Turn ON the red Main Disconnect. The white Main Power Light will light up.
8. Turn ON the amber Control Power Switch. The light within the switch and the
Temperature Controllers will light up. Reset audible alarm.
9. Turn ON the green Hose Heater Switch. The light within the switch will light up and
the Temperature Controller should begin to cycle toward its set point. If the set point
needs to be changed see Step 15 in Initial Machine Set-up.
10. Adjust the Hose Heat Power Set (clockwise) to a maximum of 45 to 50 Amps.
Tighten the shaft lock nut.
IMPORTANT: To prevent excessive pressure buildup in the heated hoses, always
bring the hoses up to temperature before turning on the Hydraulic system. The red
LED number1 on the Hose Heat Controller, when illuminated, indicates that the
heater is in heating mode. The LED goes out when the liquid in the heater is up to
temperature. However, the LED will cycle on and off, indicating that the controller is
maintaining the set point temperature.
11. Turn ON the green Isocyanate and Polyol Heater Switches. The lights within the
switches will light up and the Temperature Controllers should begin to cycle toward
their set points. If either set point needs to be changed see Step 15 in Initial Machine
Set-up.
12. Turn ON the green Hydraulic Motor Switch. The light in the switch will light up.
NOTE:
Primary heating is virtually
instantaneous. Do not turn on the
primary heaters until required for
operation. It is also a good
practice to turn off the primary
heaters during shutdowns
exceeding one half-hour.
13. Check the ratio by following the Ratio Adjustment Procedure.
14. Condition the material if required by recirculating it back to the drums.
IMPORTANT: Check with chemical supplier before conditioning material to
elevated temperature.
