Before Spraying - Micron Ulva+ Instruction Manual

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.
WIND
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:
WIND
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.
