INSTALLATION POSITION
OPERATING CONDITIONS
Ductless e2 ventilation devices with heat recovery can only function in pairs operation in opposite directions.
Each fan operates 70 seconds (50 seconds for e2 short) in supply air operation, the other 70 seconds (50
seconds for e2 short) in exhaust air operation at the corresponding set flow rates. After which both air flows
directions are changed. This assures that the total of supplied ventilation volume is equal to the total exhausted
volume. If a pair of fans in this balanced push-pull operation is installed in two different rooms of a dwelling, a
sufficiently dimensioned interconnection (undercut door, etc.) between the rooms should be installed to allow
unrestricted air movement between these spaces. Please see the product page at foursevenfive.com for videos.
Rated conditions: 5ºF to 104ºF (-15ºC to +40ºC) with relative humidity up to 65%.
During the heating period it is possible for very small amounts of condensation to form on grills if such conditions
arise. If these limitations of use are exceeded for extended periods of time, the device can be closed with the
indoor cover. Do ensure IAQ is maintained in such cases.

Installation Pipe
Make the wall openings for the assembly pipes
(e.g. by coring, core bit Ø 6.37"/162mm).
If necessary, shorten the pipe to the desired
installation length e2 minimum 11.8"(300 mm):
e2 short minimum 8" (200 mm).
Take care that the pipe extends on both sides for
finishes (sheetrock plaster, siding) with finishes
Installed flush with the pipe.
Insert the pipe, with a min. 3/8:12 (3mm) pitch
and airseal it with ROFLEX 150 gaskets,
TESCON tapes or other airtight solutions.

ASSEMBLY - ELECTRIC INSTALLATION AND ELECTRIC CONNECTION
Apply exterior finishes and waterproofing with
ROFLEX/TESCON tape combination or other
construction type specific measures.
Remove the construction protection lid outdoors. Insert
and attach the exterior grill using the integrated claw
fasteners (tighten screws). Make sure the exterior grill
mounted with the louvers directing rain away from the
tube. Exterior grill finishes are also available in:
stainless steel, grey, burgundy, and white.
Safety Instructions: Beware! Any assembly work to the ventilation device may only be carried
out when all of the supply current has been disconnected! Make sure that all electrical circuits are
turned off. All controllers of this ventilation system should be installed on a AFCI protected circuit.
⚠Electric connection only by a licensed electrician.
● The system is controlled by
Universal Control 5/UNI-FR.
● Select the location for the switch.
● Run the wiring (120V + 12V cables
to the device pairs).
● 120V cable (14 gauge).
● 12V to each fan (3 x 18 gauge solid
thermostat wire).
● Controller is wired and set per

Remove interior protection lid cover, insert heat
exchange unit into the installation pipe, ensure there is
a ⅞" gap on interior of pipe. Motor/fan faces interior.
The loop on fan unit can be used to pull unit for
maintenance.
Connect wiring to plug. Connect plug into socket and
set them into the recess of the heat exchanger casing.
Insert interior cover with filter casing, snap the interior
blind into place in open position (¼” off wall).
If cover completed covered, lift cover and rotate 180°.
Installation is now complete.
When operating the Lunos e2 using a double-rocker
switch, apply the provided sticker to the switch plate
as shown. The markings on the sticker correspond to
the following:
● Both W1 + W2 OFF = Level 0
● Switch W1 ON = Level I
● Switch W2 ON = Level II
● Both W1 + W2 ON = Level III
When operating the Lunos e2 with the optional 475
Rotary Switch, the switch positions correspond to
the following (assume a clock face):
● 12:00 (position 0) = Level 0
● 1:00 (position 1) = Level I
● 2:00 (position 2) = Level II
● 3:00 (position 3) = Level III
