STORAGE AND MAINTENANCE
Before storing the ULVA+ for long periods remove the motor and dry it to avoid
corrosion. To disassemble the spray head remove the atomiser disc and feed nozzle,
unscrew the four screws in the motor housing and then detach the front part of the
motor housing. Remove the motor by its shaft and dry, e.g. placing it in the sun for a
few hours. Re-assemble (with a new motor if the existing motor is corroded or worn)
making sure that the ‘O’ ring seals (part nos. 5403 and 5398) and terminal connecting
springs are correctly positioned. Make sure they polarity is correct N.B. the positive
terminal has a small mark and should be connected to the red wire. Check that the
small nylon air vent tube is replaced correctly within the extension tube. The sprayer
can be disassembled by removing the four screws in the battery case and all electrical
contacts cleaned with a wire brush or similar. If the extension tube is dirty where it
passes through the battery case end cap this should be cleaned. Re-assemble and
with the sprayer in the collapsed position, i.e. batteries removed, store in a dry place
away from direct sunlight. Batteries should be stored in a cool dry place.
