1.2 General description
This dust control unit has been developed using the name
TERA, and has very similar components to
the previous developed TERA range 45, 60, 75 and 90. The
number represents the maximum spraying distance in
meters.
The unique feature of the Tera series is that the droplet size
can be con gured irrespective of water quantity!
The 400V Dehaco TERA dust control units have been
primarily developed for outdoor use. This units have been
produced to spray very  ne water for dust control during
demolition and renovation applications, but can also be
used for a variety of other industrial purposes where
dust control or cooling is required.
The Demto Rotor Technology (DRT) transforms the
water into a  ne spray, which is then dispersed by the
ventilator. Because the ventilator speed, water supply
and DRT-unit can be adjusted, it is possible to adjust
droplet size, water quantity and distribution to suit any
situation!
The Tera dust control units are available in a number of
con gurations. These include:
◊ Mounting base,
◊ Skid with insert for forklift truck.
◊ Compact skid with insert for forklift truck
◊ Wall Mount
◊ Combi Skid with generator
◊ TX with water tank
◊ GTX with generator and water tank
◊ GTM with generator, water tank and o road
undercarriage

8. USE
8.1 Installation
NOTE
When using a water supply for the  rst time:  rst run the
water hose before it is connected! This helps to prevent
dirt from the water supply from entering or blocking the
 lter or DRT!
1) Determine the most suitable location for setting up
the TERA: As close as possible to the object that must
be sprayed, but far enough to operate without being
hindered! When doing so, consider:
- the water supply,
- wind direction,
- maximum distance and
- swivel range.
2) Place the TERA dust control unit on a smooth, hardened
and reasonably horizontal surface.
3) Where applicable check the oil, coolant and diesel levels
in the generator, and the water level in the tank.
4) Inspect the water  lter
5) Release both rotation and tilt transport locks to use the
rotation and tilt functions.

8.2 Grounding the Tera
Electrical current  ow, similar to water  ow, takes the path
of least resistance to the ground. For safety reasons and
equipment protection, it is important to ensure that path
is not through personnel when they come in contact with
electrical equipment. E ective grounding of all circuits and
bonding looks to provide an easy path to ground when
objectionable current  ow or fault occurs. A grounding rod
is standard delivered with the TERA 60 GTM / GTX.
1. Fasten the wire on the TERA 60 with the wingnut.
2. Drive the rod in the ground.
