maintenance cover, and pull the maintenance
cover up.
(Looser the hinge and detach the maintenance
cover.)
2. Take the air filter out.
Take the air filter with each contained to the

❈If it adheres to the ceiling in reverse, it is equal
to the left/right topside of the Total heat
exchanger.
3. Take the Total heat exchanger out.
Catch the handle and then take the Total heat
exchanger out from the main body. (2 units)
CAUTION: Take care to ensure that you
could not damage when taking the air
