Mounting with the ceiling mounting plate(optional)
In case of installation of HRV to the ceiling, ducts can be installed in advance and secured with special
supporting components. Ceiling finishing works can be done before final installation of HRV.
The ceiling mounting bracket is usually fastened to the ceiling with four 8 mm threaded rods. Sound-
absorbing rubber gaskets should be used with the threaded rods for sound and vibration dampening. One
of advantages of such threaded rod installation is prevention of sound propagation to ceiling. However, if
necessary, ceiling mounting bracket can be also connected directly to the ceiling.
While installing the HRV drainage of the condensate should be taken into account: the HRV should be
reclined slightly backwards. The backside of the HRV bottom must be at least two millimeters lower than its
front side.
Steam barrier installation
When installing a steam barrier it is advisable to use the ceiling mounting bracket as an aid. Size of holes
punched in the steam barrier tape should be little smaller than the diameter of the duct holes on the ceiling
mounting plate.
When lifting up the ceiling mounting plate to it’s place, press the steam barrier tape against the top surface
of the mounting plate and use adhesive tape if necessary to ensure tight installation.
The steam barrier plastic tape can be sealed carefully to the edges of the mounting plate with adhesive
tape.
'FAIR' HRV are also available with a rubber plate which makes sealing of the steam barrier easier.
Liftning up the unit
1. Set the cellular plastic rings around the outlet ducts.
Prior to installation the heat exchanger can be
demounted from the HRV in order to reduce the weight
and make the installation easier. Additionally, the HRV
door can be removed as well by removing the hex m6
bolt from the bottom hinge.
2. Lift the HRV carefully towards the ceiling mounting
plate. Align the hooks placed on the side of the HRV
towards the slots on the ceiling mounting plate. Lift HRV
upwards till the hooks lock up to their first position.
3. Make sure that the cellular plastic rings have
remained on their places after the installation and the
electrical wiring passes freely, and there are not extra
objects inside the unit.
4. Applying more force lift the unit up in order to lock up
the both hooks of the HRV.
5. Make sure that the cellular plastic rings are tightly
fastened against the ceiling mounting plate and lock the
fastening with the two screws supplied.
6. Make sure that the HRV is declined enough in order
to lead the condensing water out of the unit.
Attention! For the right handed model( FAIR 80 R) the ducts are located as mirror image.
