Adjust unit to installation conditions

The outside air side of the KWL unit can be adjusted as required.
Furthermore, the supply air supply can be at the top or bottom of the unit.
Adjustment Exhaust air side
In order to adjust the exhaust air side, remove the four screws in the front and back of the unit and remove the cladding
parts. Then turn the unit by 180°. If the supply air supply should be at the top, replace the unit cladding and re-attach
using screws. Otherwise, keep the front side open.
Adjustment Supply air supply top/bottom
In order to adjust the supply air supply, remove the unit door (if not open yet) and remove the heat exchanger.
Carefully remove the supply air fan unit on the metal bracket towards the middle of the unit. Loosen the two cable con-
nectors and pull plug from the fixing lugs.
Then turn the supply air fan unit by 180° (open fan side now facing down) and replace the cable connector in the pro-
vided holders (round/rectangular). Connect plug, then re-insert the supply air fan unit back into the EPP body. Check
for tightness.
