Dimension drawing (all dimensions in mm)

Installation Position

Decentralized fans with heat recovery of the type e² mini only function in pairs in alternating operation.

One device operates for 50 s in supply air mode, the other for 50 s in exhaust air mode at the respec-

tive flow rate set. After this, the direction of air flow is changed. This ensures that the total flow rate

supplied is the same as the total air flow ejected. If a push-pull device pair is installed and operated in

two different rooms in the apartment, a sufficient volume of air must always be ensured between these

two rooms via adequately large dimensioned overflow air passages.

Minimum distance recommended when in-

stalling a device pair in one wall:

Scope of application

Temperature range: - 15°C to + 40°C

Can be used at a relative humidity of up to 65% inside the apartment. Low condensate formation

may occur during the heating period. If limits are exceeded, switch off the device and close the interi-

or screen. Ensure supply of fresh air by opening the window.

Other outer grilles available on request!

Assembly—Assembly Tube and Outer Grille

Prepare wall cavities for the assem-

bly tube (via core bore hole, drill bit

Ø106 mm). If necessary, shorten the

tube to the required installation

length. Make sure there is a protru-

sion of the tube on both sides to

bridge the plaster thickness (after

plastering, the tube must be flush

with the plaster). Insert the tube and

seal it all round (Assembly adhesive

Order No. 038 733).

Apply the inside and outside plaster.

In the case of an outside closure to

be plastered, first replace the plaster

protective cover with the outside

closure.

Remove the outside plaster protec-

tive cover. Mount the outer grille

using the integrated claws (tighten

the screws). The solid plastic out-

side covers provided by Lunos en-

sure high resistance to driving rain

and can be used in the Stress

Group III pursuant to DIN 4108-3

(2012-04). Metal or metal-coated

covers can be used in Stress Group

I pursuant to DIN 4108-3 (2012-04).

In the case of buildings exposed to

wind or the risk of strong winds and

rain to the outside covers, further

measures of weather protection may

be required.

Assembly – Electrical Installation and Electrical Connection

Caution! All assembly work on the fan must only be carried out when power has been disconnected from all

terminals!

Make sure all connection lines are de-energized before connecting the fan to the power supply !

(disconnection from power supply with at least 3 mm contact opening, e.g. all-pole circuit-breaker)

Each circuit connected to the ventilation system must be fitted with residual current protection (e.g. a RCD

switch)! Electrical connections must be carried out by qualified staff only!

Additional installations and electrical components in this ventilation system are not admissible!!

Triggering can be made via the

universal control 5/UNI and the

added feature control TAC. Re-

spective installation instructions

apply accordingly.

Select the position of the switch.

Slit the cable ducts (power cable +

cable to device pairs) and the

tubes (2 cm deep). Install the pow-

er cable (e.g. 3 x 1.5 mm² ) and

the cables to the device pairs (e.g.

3 x 0.75 mm² ). Prepare the cables

to the device pairs in the tube.

Circuit and switches are connected

in accordance with the wiring dia-

gram below.

washer), put the design screen

back on.

The vents must not be obstructed

or covered.

Reset the filter change display by

rocking the rocker switch W1 once.
