•
After use – switch off the equipment by reversing the above procedure. We recommend you
disconnect the water supply at the inlet coupling and open drain valve (T) which is located just behind
the water pressure guage (see adjacent picture). This allows the unit to drain empty of water and is an
absolute requirement during frosty weather.
Drain Valve (T)
In-use routine maintenance
:
•
The water supply passes through an in-line filter which will gradually block if your supply contains
suspended solids (and most supplies contain some). Periodically unscrew the filter housing
hexagon nut, remove the filter mesh, clean in water and re-install.
•
If the water jet is uneven clean the nozzles (see adjacent picture) - unscrew them and rinse in
water; if you are in a “hard water” area (water with a high calcium carbonate content) you may
need to soak the nozzles in an anti-scale solution; rinse in clean water before re-fitting.
•
The “curly” power cable is subject to mechanical stress particularly when the oscillation function
is selected; check for excessive wear or abrasion.
If in doubt ask for advice from the supplying hire depot.
Trouble-Shooting:
3.
WARNINGS:
Keep clear of fan inlet and outlet, never remove the fan inlet and outlet guards; do not attempt to open machinery
casings. The Super Mosquito discharges a plume of air and water mist at speed - don’t walk inside the plume within 2 metres
of the discharge nozzle; always wear eye protection. This machine works best with clean water - avoid using dirty water and
water with high levels of suspended solids; do not use stagnant, or fetid water.
The machine is capable of slow rotation / oscillation. Ensure nothing protrudes over the trailer – a minimum 1 metre clearance
around the trailer platform is recommended; do not rest anything on the trailer that might obstruct the mist cannon’s rotation.
If the machine sustains damage the equipment must be taken out of service and returned to the supplier.
The Super Mosquito’s drawbar trailer is equipped with a 50mm ball coupling and supplementary break-away restraint – only
connect to a vehicle with a corresponding coupling. The trailer is un-braked; when decoupling use wheel chocks and the
trailer’s stabilising legs to prevent the trailer from rolling. Keep trailer secured to towing vehicle by break-away restraint when
disconnecting the tow ball coupling; remove the supplementary break-away restraint only when you are satisfied that the
wheel chocks and/or stabilising legs have effectively secured the trailer.
4.
AFTER USE:
on completion of work disconnect machine from power and water supply and open drain valve (T) ;
always
clean
off the outside of the machine before returning to supplier. Store in a frost-free environment when not in use. Make sure the
trailer is left secure with wheel chocks / stabilising legs deployed so that it cannot roll.

Problem
Cause / Solution
Fan won’t start ?
Reset emergency-stop button, check power connection, is voltmeter display
showing 110v ? Possible RCD tripped inside control cabinet.
Fan tries to turn but supply trips to off ?
Insufficient current / voltage to start fan. Minimise supply cable length, use heavier
guage cable, check supply can accommodate start load.
Mist Pump won’t start / Mist Cycles On-Off Incoming water supply insufficient - dry-run protection stops mist pump when
water pressure falls below 2 bar - increase incoming water supply pressure / flow.
Mist Pump on but little or no water mist
In line filter or nozzles blocked – clean.
Oscillation / rotation function won’t start
Controllers not yet initialised (requires up to 60 seconds).
Machine suffers excess vibration ?
Imbalanced fan due to debris build up on fan blade, or damage to fan blade. Stop
machine & remove debris; in case of damage to blade contact supplier.
