CLEANING & MAINTENANCE
6.1.
General:-The Atomiser
is not especially sensitive to particulates
in its input. The unit handles normal tap water (including hard
water) without needing special treatment. Only if there are
significant amounts of undissolved solids in
the liquid is there a need for filtration.
If a sudden blockage
or loss of flow does occur, then the Feed Tube should be removed
from the Atomiser and inspected first, as this is the part through
which the liquid flows first.
The condition of the Spray
Head can be judged from appearance. Over a period of time very
small particles accumulate inside, impairing its performance,
so replacing this part becomes advisable. If
the Spray Head is distorted, cracked, or very dirty it should
be replaced.
When used with average-quality tap water at
about 5 litres/hour, the Spray Head should be replaced about
every 2,000 hours' running. Higher flows and liquids with more
particulates may mean a shorter interval. Liquids with few particulates
may mean an indefinite lifetime for the Spray Head.
You can probably remove both Feed Tube and
Spray Head, without dismounting the Atomiser from its normal
running position. First, disconnect the liquid input to the
unit, and run it for 10 seconds to expel all liquid from inside.
Then switch off the power supply.
6.2.
To Replace the Feed Tube:-Using
a spanner (½" or 13mm A/F), unscrew the Feed Tube from
the top-plate of the Atomiser and carefully withdraw the Feed
Tube from the shaft.
Don't bend
the Feed Tube! If the Feed Tube is bent it might
rub against the inside of the Atomiser shaft causing noise and
vibration, and perhaps damage to the Feed Tube as well.
If there is a plastic Spray Tip fitted to the
lower end of the Feed Tube, check that the holes in it are clear
- use a pin to clear them if necessary. The Spray Tip is screwed
into the end of the Feed Tube and can be removed and replaced
if necessary (Note! it has a left-hand thread
- clockwise to remove, anti-clockwise to replace).
Insert Feed Tube
back into the Atomiser carefully, and tighten up well, using
the spanner.
6.3.
To Replace the Spray Head:- Hold the Spray Head
firmly by the (black) non-porous discs at each end which retain
the porous material, and unscrew (by hand) the End Nut.
Hold the body of the Atomiser in one hand,
and with the other, pull the Spray Head off the Shaft, slowly
but firmly - it is a close fit.
If you have removed both the Feed Tube and
Spray Head, then you can clean the inside of the Shaft, with
a long cotton-bud. Use a pin to clear any blocked holes in the
Shaft.
Now push a new Spray Head on, as far as it
will go (up to the seal).
Replace the End
Nut, making it finger-tight.
Threadlocking
adhesive must not be applied!
