Using a 10mm spanner loosen the two bolts, one at

each end of the air discharge opening, by 2 turns. Do

not remove these two bolts completely.

Remove the row of fixing screws along the whole

length of the drain tray (see picture).

The drain tray now hinges down along its front edge

and the inside surface of the tray can be cleaned.

Remove all debris and deposits from the coil face,

drain tray, outlet pipe, condensate hoses and the

condensate disposal system.

Check there are no kinks in condensate hoses. If the condensate pump is a peristaltic

type change the rubber pump head tube. Refit drain tray opposite to removal

Once the air curtain has been cleaned, visually inspect the air curtain components.

Ensure pipe temperature sensors are located in their pockets and any foam insulation

covering these pockets is un-damaged. Check that the thermal overheat cut-out switch

(two on a HP2000DXE unit) has not tripped (see Section – Commissioning, Page 20).

Check all electrical connections and terminals within the unit are tight and that crimp

connections have not become loose.

Refit the bottom access panel and air inlet grilles with filters. Switch on the electrical

supplies and fully function test the air curtain to ensure correct operation (see Section –

Commissioning, Page 20).

Reset the Filter Dirty Indicator after the service by

pressing the Reset Button for at least 5 seconds (even if

the indicator has not gone flashing red) and hand back the

unit to the end user.
