A fork lift with lifting force of at least 2200 lbs. and with minimum fork length of 55 inches must be used.
Insert the forks in the proper roll over protective spaces.

HANDLING WITH CRANE: suitable for both TRAILER and POLE versions with or without base.
Use chains or bands with lifting force of at least 2200 lbs. and complete with two lifting hooks. Verify that the
bands or the chains are long enough to avoid them touching the metal parts of the Machine.
Hook and fix the band or the chain to the provided blocking pins only.
INSTALLATION
Before the installation, verify that the ground is adequate to support the weight of the Machine and in the
case of POLE versions verify that the ground is flat and even. The installation must be carried out only by
qualified and authorized staff.
OPERATING PRINCIPLE
The HD 160, HD 230, and HD 300 are dust suppression systems. These machines use water atomization to
capture dust particles (including silica) in the atmosphere.
MAIN COMPONENTS
The machine includes a Cannon, a Multi-Zone Crown, a Column Frame, a Filter, Zone Valves (electric
versions are optional) a PLC Control Panel, and a Pump.
Cannon and Multi-Zone Crown
The ventilation and spray system unit have sufficient water flow to accommodate the air volume and thrust
created from the cannon propeller. The water spray nozzles are located along the circumference of the
crowns. A heating kit (optional) can be installed in order to prevent icing.
Column Frame
The FogCannon is installed on a column frame where the raising and rotation devices are also mounted.
These devices, which can be controlled electrically, manually or in Remote mode, serve to adjust the rotation
angle and to make the fogcannon work within the selected angles set up at the user’s own discretion.
Filter
The unit is fitted with a 100 mesh filter that removes impurities that can clog the nozzles. An additional pre-
filter may be recommended for some applications.
Zone Valves
Manual or electric (optional) valves control the water flow to the various zones on the crown. The HD range
includes a crown that has 2 or 3 zones depending on the machine design. The unit can operate with
individual zones or all zones simultaneously. The water flow depends on the number of zones working, the
nozzle size in each zone, and the operating pressure of the pump. See the OPERATING FLOW OPTIONS
table below.
The electric zone valves (optional) are controlled from the PLC panel or from the Remote Control
Transmitter. When the electric valves are turned off, they automatically drain any remaining water in the
zone lines. It is recommended to open all drain ports on the unit after each use.
PLC Control Panel
The PLC control panel allows the starting of the fan, the pump, the electric zone valves (optional), and
control the electric oscillation and electric tilt (optional) of the FogCannon. The panel also allows for
programming the cycling of the unit.
Pump
The pump is housed on the outer column frame and is used to increase the water supply pressure.
Increased pressure will improve the atomization of the water droplets and the effectiveness of the unit. The
pump is equipped with a pressure gauge and pressure switch which will terminate the pumps operation if the
water supply is insufficient.
