over the heat exchanger

now be lifted/pulled
carefully out of the core
Pour a mild soapy solution through the four open sides of
the heat exchanger (use standard washing-up liquid) Let is
soak for 5-10 minutes and then rinse under running water
Dry of the exterior of the heat exchanger, and gently slide
the heat exchanger into the unit again
When remounting the exchanger, the round seal should be
inserted last This is best done by 'locking in the two ends'
first and then pushing the rest of the seal into place
Clean interior surfaces of the unit with a wet sponge or cloth
(use a mild soapy solution)
UNDER NO CIRCUMSTANCES use solvents to clean the foam
parts as solvents can dissolve the special foam material
Avoid spraying water onto the main circuit board If you do
happen to spill water onto the circuit board, tap the circuit
board lightly using a dry cloth Leave to air dry for min 24
hours before reconnecting the power
Assemble the unit in reverse order:
• install the foam front panel
• secure the panel with the three metal rails
• tighten torx screws
• reinstall the front panel
You are now ready for another 2 years of troublefree service
