To shut off burners, turn fuel off before stopping blower or turning off air
When burners are not in use, close heat exhaust stack cover to prevent loss of heat and to keep water
from entering stack opening.
Setting Hydrostatic Controls.
To set hydrostatic controls for spraying requirements when circulating in tank, pump speed should be: 10-15 gpm per ft of
bar length with 1/8 in. Nozzles. Example: 160-240 gpm for 16 ft spray bar length.
Prior to circulating in bar, pull main hydraulic control knob (10, fig. 2-1) if distributor pump tachometer
(GPM) (1) reads over 160 gpm to reduce pressure in spray bar.
Do not change control knob stop setting.
Place the control levers (see fig. 2-9 for location) in the following positions:
Quadrant Control Lever - Circulate in bar
Intake Valve Lever - Down
Butterfly Valve Lever - Out (normal)
Drain Valve Lever - Forward
Bar Raising Lever - Up or down (release lock assembly)
Transfer Valve Lever - Distribute
Vacu-flo Valve Lever - Up
Circulate long enough to insure removal of all air from bar and to heat valves. Pump speed should not
exceed 160 gpm. Material will circulate in ends with extensions folded or in spraying position
Place the control levers in the following positions
Quadrant Control Lever - To distribute position (fig. 2-3). When in "Circulate in Bar" position, raise
handle of catch lever to enter dog into slot of outer shaft. Raise handle to close micro switch.
