BEFORE SPRAYING
Since wind is used to distribute and deposit the spray the ULVA+ must
always
be
held downwind of the operator.
Never
spray without a crosswind of at lease 1 m/s
(3.6 km/hr) since good results depend on overlapping spray deposits from successive
spray passes i.e. an incremental spraying technique.
It is therefore
vital
to check the wind speed and direction before spraying. The
diagrams below show acceptable wind direction and how the spray route should be
planned:

Best results will be obtained in a consistent crosswind of between 1 and 4 m/s.
Never
spray when there is no wind, or wind direction or speed is changeable, since the
operator then risks being contaminated by the spray.
Always
hold the spray head at
least one metre away from any part of the body to avoid the risk of direct
contamination by the spray.
Never
touch the atomiser disc when it is spinning.
