Droplet eliminator
Droplet eliminator DE must be installed downstream of the
cooling coil in the duct cooler, viewed in the direction of air
flow.
Remove the drip tray from underneath. Push the droplet elimi-
nator up until the holder secures it in position (see Figure 5).
Carefully check that the air flow is in the direction of the arrow
on the droplet eliminator and that the drain holes face down-
wards towards the drip tray (see Figure 3).
Cleaning
In order to ensure full cooling capacity of the duct cooler, the
finned coil and the droplet eliminator, if any, must be regularly
cleaned. The intervals between cleaning are entirely dependent
on the cleanliness of the air and on how well filters and the
system in general are maintained.
CAUTION: Make sure that there is no one underneath the
drip tray when it is being removed.
Disconnect the condensate outlet, and blank off the connection
so that any remaining condensate will not run out.
Remove the drip tray by releasing the excentric lock on the
front.

Lower the drip tray about 2 – 3 cm and then move it towards
the back so that the locking mechanism at the back will be
released. The drip tray is held captive by hinges the rear, but it
can easily be released to enable it to be removed from the cooler.
If a droplet eliminator is fitted, push the holders to the side (see
Fig. 3), and remove the droplet eliminator for cleaning with
compressed air or warm water.
Then clean the inlet side of the coil with a soft brush and the
entire coil can then be cleaned by means of compressed air or by
vacuum cleaning. Blow away the dirt in a direction from the
outlet side of the air towards the inlet. Take care not to deform
the
thin fin edges.
Clean the bottom of the drip tray and check with your finger
that the condensate outlet is not clogged with dirt. Then fit the
droplet eliminator, if any (see under Droplet eliminator), the
drip tray and the anti-condensation insulation.
