Place valves in the following positions (Circulate Tank, Figure 2-2, Sheet 3):
(a)
Place valve #1 (8) in the tank position.
(b)
Open valve #2 (9).
(c)
Close valves #3 (10), #4 (11), #5 (12), and #6 (13).
(6)
Increase engine RPM to 1500.
WARNING
Do not increase pump speed above 50 GPM during initial circulation. Excessive
cooling of material as it passes through cold pipes and pump will result in
expansion of material and may cause overflowing of supply tank.
(7)
Move pump transmission control lever (14) forward (FWD) and run system at 25 GPM.
NOTE
Pump GPM may drop during first several minutes of re-circulating as material cools
from piping and pump. GPM may be increased as long as 50 GPM is never
exceeded.
(8)
If pump, inlet, or return piping are blocked due to solidified material, apply heat from portable torch.
Refer to Portable Torch Operation (para 2-25).
