CLEANING & MAINTENANCE

Maintenance Requirements

** Filters MUST be used, otherwise the face of the energy exchange core will become blocked by dust.
** The filters existing in the unit are usually able to keep the energy exchange core clear for many months.
** Finer filters can be used but MUST be cleaned more often
Clean the face of the energy exchange core annually:
1. Remove the filters
2. Remove the core latch and pull out the core
3. Vacuum the exposed faces of the energy exchange core with a soft brush attachment
4. After maintenance, re-install the core and filters
5. Vacuum out dust from the rest of the unit case. Dust collects only on the entering faces of the energy exchange core.
The interior of the energy exchange core stays clean even if the core faces are covered with dust
CAUTION!
DO NOT WASH THE ENERGY EXCHANGE CORE:
The energy exchange core can be replaced but is expensive.
The core is secured to the unit by the core latch, when the unit is installed as installation B.
If the core latch is disengaged, the core can fall out, causing damage or injury if not prepared after the door swinging down.
Ensure the core latch is secured until you are ready to remove the core for maintenance.
Re-engage the core latch after maintenance to secure the core in place.
