5.2.3 Manway (standard)
The manway serves as an entry point for performing necessary repairs or
cleaning work on the vacuum tanker.

Manway
The container must be cleaned and well ventilated before/during any work in the tank. Open
all gate valves and covers. The container must be depressurised.
Caution: risk of suffocation in the case of insufficient cleaning or ventilation!
5.2.4 Hydraulic gate valve, rear (standard)
The hydraulic gate valve is used to open the container for discharging the slurry.
It is operated via the hydraulic control of the tractor or tank.

Never reach into the gate valve or stopcocks. Risk of crushing!
5.2.5 Pressure relief valve & positive/negative pressure relief device
(standard)
The pressure relief valve prevents the formation of overpressure inside the tank
during slurry discharge. The factory setting is 0.5 bar.
(The valve opens as of this pressure.) The valve setting must not be changed.
The negative pressure relief device opens in the case of excessive negative
pressure during the suction process.

5.2.6 Filling dome preparation (standard)
The filling dome features a fixed cover as standard.
A mechanical or hydraulic filling mechanism can be retrofitted at a later stage.

The container must be cleaned and depressurised before performing any retrofit work.
The filling dome must not be used as an entry point.
Only the designated manway must be used for this purpose.
5.2.7 Siphon & additional siphon (standard)
A siphon and additional siphon prevent over-suction and thus contamination of
the compressor during the filling process. As soon as the container fills up, the
slurry lifts the ball into the air inlet opening and seals it.
