5 Maintenance
5.1 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 (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 chapter 3.3), the drip tray and the anti-condensation
insulation.
