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 2000 and 2500 unit) has not tripped (see Section – Commissioning). 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 filters. Switch on the electrical supplies and fully
function test the air curtain to ensure correct operation (see Section – Commissioning).
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.
