Initial control/valve settings and adjustments before the WWET/T is used in the vacuum (tank filling) mode
are as follows: (Refer to WP 0004 00 for location of controls)
Moisture trap drain valve
Intake valve (suction) hydraulic control knob
Drain valve (discharge) hydraulic control knob
Chopper tube/wand PVC ball valve
Vacuum pump control
Engine emergency shutoff
The normal operational cycle of the WWET/T consists of connecting the trailer to a prime mover, moving
it from its designated parking position to one or more locations for wastewater evacuation (tank filling),
moving the trailer to the designated disposal site, draining the tank and returning the trailer to its
designated parking position.
The actual operational cycle can be varied and should reflect local requirements. If the collection and/or
discharge points are relatively far apart, a partially filled tank can be temporarily stored in the trailer until
the tank is filled to capacity before draining.
Connecting WWET/T to Prime Mover
To connect the WWET/T to a prime mover proceed as follows:
Ensure that two persons (not including the prime mover operator) are
available for this operation to properly guide the prime mover into position and
connect the trailer. Trailer parking brakes must be ON and chocks in place to
avoid injuries from a moving trailer to avoid serious injury/death between the
prime mover and the trailer when guiding the prime mover into position.
1. Ensure trailer parking brakes (figure 1, item1) are ON (brake handles in horizontal position) and
chocks (figure 2, item 1) are in place.
