Vaventis fresh-r On-The-Wall Installation Manual page 25

Does the upper duct pipe need to be positioned in a
2 degree angle?
No, this can be level but it is no problem to
mount it under a 2 degree angle, the upper
duct does not drain any condensate, it only
guides incoming air.
Can we change the door to swing direction?
Yes. First the electric cable needs to be
removed.
Then remove the 2 hinge bolds & nuts and
mount them on the other side. Don't forget to
place back the electric cable.
Should we first mount the upper and lower duct on
the unit and then mount the Unibody on the wall?
Yes, because the connection of the PVC duct
pipes and the EPP covers needs to be checked
visually before mounting the fresh-r
wall.
What should we do with bag C?
This is a spare part kit, store it at the bottom
of the unit.

How can I operate the unit?

What does the smiley tell me?
They indicate the air quality, refer to user
manual.
Does the unit measure RH or CO
Yes, it measures both, please refer to user
manual.
What maintenance should be done?
Rinse heat exchanger with cold water every
6 months, and clean upper and lower duct pipe
every 2 years, refer to user manual.
The unit makes noise, is that correct?
If the orange or red face icon is lighted it is
correct. The air quality is not good enough and
it substantially increases the ventilation rate. If
the green smiley is on and it makes more noise
then 30 dB(A) it could be very humid inside,
especially just after construction. If the green
smiley is on and the building is not humid but
the unit makes noise for more then 3 hours in
a row, contact your supplier. Refer to user
manual.
How can we reduce the noise?
Wait till the green light face lightens. If this
takes too long, open a window. Refer to user
manual.

air is coming into the room, what happens?
If it is freezing outside, it is in defrost mode
and it de-freezes the heat exchanger by
blowing warm air out, so it can again work at
optimum efficiency. If it is not freezing outside
and the fresh-r suddenly starts to make
®
noise, contact your supplier. Refer to user
manual.
