6.3 Opening and Closing the Housing
The stacked housing elements are held together by two locking arms that hook into the diffuser.To open the system
follow the steps below.
1. Disconnect the IQAir system from the power supply before attempting to open the
system.
2. Press the first locking arm outward, using both thumbs as shown. Press just hard
enough to release the arm from its snap-in position in the diffuser. Disengage the
other arm in the same way.
3. Pull both locking arms evenly outwards until they snap into place and remain open.
Access to all filter elements is now possible (to change a specific filter, refer to the
appropriate section below).
4. To close the housing,simply push the locking arms inwards simultaneously until they snap back into the housing.

6.3.1 Troubleshooting when closing the Housing
If the IQAir system does not close properly, the upper part of the system
may be offset against the lower part.To solve this problem, simply open
both locking arms again and push both locking arms in simultaneously.
6.4 Replacing the Pre-Filter (Filter 1)
1. Open the locking arms, making sure they
are fully extended outward. For details,
refer to the section 6.3.
2. Opening the arms will cause the upper
part of the housing to separate from
frame 1.This will leave a narrow gap.
3. Place your hands on opposite sides of
frame 1,lift it slightly and pull it out slowly.
As the frame is withdrawn from the
system, tilt it progressively upward to
remove it completely.
