IMPORTANT USER GUIDANCE
ENVIROGARD SUPER-MOSQUITO
WATER MISTING CANNON
READ ALL THE INSTRUCTIONS BEFORE USING THE EQUIPMENT
General Specification
: The Super Mosquito is a high capacity misting fan which produces a
plume of water droplets that will envelop and suppress airborne fugitive dust much more
effectively than water sprays or jets - and using much less water. The Super Mosquito has a
25 metre throw (still air conditions) and can oscillate through user-selected arcs of 0, 40,
120, or 360 degrees to treat much larger areas than fixed systems. It is easy to use, easy to
clean, and
operates from 110v site power using water from a 15mm hose
.
The Super Mosquito is on a small twin axle trailer so it can be easily relocated and
positioned. With water it can be used for dust suppression or for cooling purposes; without
water it can be used just as a high capacity ventilator. The Super Mosquito from Envirogard
is “
roll up, plug in, and switch on
”.
1.
INSTALLATION:
the Super Mosquito road-tow trailer (un-braked) may be towed or
pushed into place; it can be used inside or outdoors. If it needs to be lifted into place use
spreaders and secure lifting strops under the trailer (do not lift by attaching to the fan
casing or its support pylon). Do not operate the unit while it is suspended in the air !
•
When choosing a position for the unit first check there is nothing which can obstruct the fan intake or discharge. Don’t
locate the unit where material can be entangled or drawn into the fan – it might be discharged at high speed. To treat larger
areas the Super Mosquito is capable of rotating on the trailer platform, spraying water mist through user-selected arcs up to
360 degrees - so ensure there are no obstructions close by / protruding over the platform; as good practice maintain as a
minimum 1 metre clearance around the trailer platform.
•
When the rotation / oscillation function is selected the centre of gravity of the equipment will change as it rotates. For this
reason do not rely solely on wheel chocks to secure the equipment when in operation - these are only an aid in positioning
during relocation of the equipment. Once in position extend all four telescopic legs (see above picture) onto a firm surface
so the trailer is secure, stable and level.
•
Set the desired vertical angle of the mist discharge by grasping the handle on the fan casing, pull out the locking knob, tilt
the fan to the desired angle, then release the knob to lock the fan position once again.
•
Couple a water supply to the machine and ensure the incoming-water lever valve is closed at this
time (pictured below right). Use clean - preferably potable (drinking) quality - water.
2.
OPERATION:
the unit is equipped with a 110v chassis plug – connect power using a corresponding
32A 110v socket on a trailing lead; if using a generator we recommend 5KvA to accommodate start-up
surge current. Once the supply is live an indicator lamp on the control cabinet will illuminate, and the
digital volt meter will display the supply voltage.
Note: once power is connected it may take up to 60 seconds for the control system to initialise; during
this time the oscillation / rotate function is not available. To start the machine – ensure the control
cabinet (pictured below) Emergency Stop button is pulled out then:
•
Using the Fan Direction Control (Z) rotate the fan so it points where you want it to throw the water mist.
•
Press the Start button (S); the fan will spool to its operating speed within a few seconds.
•
Now open the water supply valve (pictured right) – providing 2 bar pressure is available from your site supply
the mist pump will automatically turn on within a few seconds and produce a fine mist from the spray nozzles.
•
When you want the Super Mosquito to oscillate from side to side – first select the arc range you want [40, 120
or 360 degree] using switch (P). Then to start oscillation press button (Q) once; to stop oscillation press
button (Q) again. The direction of the fan when oscillation starts will be the centre of the swept arc; a light
beacon will flash whenever mist cannon oscillation / rotation is active.
In case of emergency the equipment can be stopped by pressing the Emergency Stop on
the control cabinet, or by disconnecting the 110v power coupler.
Note: pressing the emergency stop does not disconnect the power supply (control circuits remain energised);
power and water must be completely disconnected before undertaking maintenance or opening the control cabinet.
