4.2 Installation of the unit
The ventilation unit cannot be mounted on a floor. Condensation drains must be fitted to the unit. It is
designed to be wall mounted. Below is backplate on the wall, ready for remounting the unit:


Remove the front and top cover and take the EPP unit out of the metal backplate.

Offer up the backplate to the wall and mark out the mounting points, ensuring the unit is level.

Secure the backplate to the wall using appropriate fixings.
If installing on a hollow wall, suitable anti vibration fixings may be required.

If required, the unit can be fixed using left and right side fixing holes (E.g. If the unit is fixed inside a
cupboard).

Remount the unit into the backplate and secure the top and front cover.
NOTE!
Check that the unit is positioned level in order to ensure proper condensate discharge.
4.3 Condensate discharge lines
There are two condensation collection trays built into the expanded poly propylene housing (EPP) of the unit
and two (provided) condensate collection unions must be fitted to the discharge points on the bottom side of
the unit.

Remove the front cover from the installed unit. Take care to remove the umbilical connector from the
Display PCB.

Pull out the EPP cover and remove the heat exchanger using the pull strap.

Remove the back-nuts from the condensate unions (provided) and then push them through the two EPP
drain holes. Note: Additional leak proofing of the union may be required.

Secure the two unions to the backplate using the back nuts.

Replace the heat exchanger and EPP cover.

Re-fix the front cover, remembering to reattach the umbilical connector to the Display PCB.

Connect drain hoses to the two unions and take to a suitable drain trap.
NOTE!
The location of the ventilation unit, as well as the condensate discharge hoses, must be frost-free!
When connecting up to the drainage pipe of the building, the following points must be observed:
