IMPORTANT USER GUIDANCE
ENVIROGARD SC15 WATER MISTING
CANNON
READ ALL THE INSTRUCTIONS BEFORE USING THE
EQUIPMENT
General Specification: The SC15 is used for dust and odour suppression both inside and
outdoors - typically in demolition, recycling, and general construction applications. The
system integrates a 1140 Litre water bowser, key start 110v generator, mist pump, spray
cannon, and road-spray boom on a twin axle trailer approved for highway towing.
The spray cannon produces a fine water mist; airflow from the fan propels this up to 15
metres horizontally or 8 metres vertically (in still air). A manual turntable allows a near
360 degree arc of rotation - the fan is simply turned in the direction that water mist is
required; a manual tilt control allows the vertical throw to vary from -15° to +60°.
The SC15 is equipped with a road-spray boom fitted low-level at the rear of the trailer;
this can be selected - instead of the spray cannon - by a simple turn of a lever.
For indoor or static applications the unit can operate using 110v site power in place of the on-board generator – this simply requires
a 110v 32 amp socket to be plugged-in to the SC15. The SC15 is a “roll up, switch on” hire product available from
Envirogard.
1.
INSTALLATION: the SC15 Bowser is equipped with a standard 50mm coupling, 12v road lights, and should be towed into place.
When choosing a position for the unit 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. The spray cannon is
capable of rotating nearly 360° so ensure there are no obstructions close by – maintain at least 1 metre clearance.
Park the trailer on a firm surface so the trailer is secure, stable
and level within 10°. Apply the hand brake and chock the
wheels before decoupling.
Set the desired tilt of the fan by grasping 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.
Similarly rotate the fan so it points where you want it to;
release the knob to lock position once again.
Fill the bowser with clean (preferably drinking quality) water -
max. capacity is 1140 Litres. Water temperature should be
lower than 25°C to maintain a good hygiene standard; at higher
temperatures regularly re-fresh and / or sanitise tank.
2.
OPERATION: the SC15 is powered by an integral generator, or
you can connect a 110v site power supply.
By generator: check oil and fuel level before starting – ensure
generator is always switched off and is cool before re-fuelling.
To start the generator open the fuel valve and set the choke
lever (see photos adjacent), then rotate the ignition switch to
“Start”. Release once the engine fires and gradually return the
choke lever so the engine runs smoothly.
TO STOP GENERATOR IN EMERGENCY PRESS THE “EMERGENCY
STOP” BUTTON ON TOP OF THE MACHINERY CABINET.
Don’t crank starter motor for more than 10 seconds; if the start
battery is flat turn ignition switch to “ON” - use the recoil start.
ALTERNATIVELY
to power the SC15 from a 110v site power supply
turn off the SC15’s generator; open access panel
on the off-side of the machinery housing & identify
the 110v power coupling [image mid-right].
Disconnect the generator’s trailing socket from
the chassis plug. Now couple to the chassis plug a
110v 32A trailing socket from the site power
supply. Route the supply cable through the slot in
the access panel [image far right]; close the panel.
Spray Cannon Controls: are located on the front of
the machinery housing (image right). Be mindful
of the fan intake / discharge during their operation.
To start the Spray Cannon rotate the control knob to (1) PUMP - wait approx 5 seconds - then select (2) PUMP + FAN. The
unit will take approximately 10 seconds to spool up to full speed, and a fine water mist will be expelled by the fan wash.
TO STOP THE SPRAY CANNON IN EMERGENCY TURN THE CONTROL KNOB TO THE “0: OFF” POSITION.
TO STOP THE GENERATOR IN EMERGENCY PRESS THE “EMERGENCY STOP” BUTTON ON TOP OF THE MACHINERY CABINET.
