nected to the operating switch via the
left-hand gland (7) (see fig. 5 and 6). All
the glands and the pull relief must now be
tightened.
The KPM(e) should now be guided over
the adhesive plate until the black edge
ring lies on the upper surface of the
adhesive plate. This applies slight pres-
sure to the foam located in the cowling.
The KPM(e) must then be screwed to the
adhesive plate using three self-tappers (8)
where indicated on the cowling.
The fan may not extrude more
than 5.° from the lead.
There is a hole in the bottom of
the operating switch to allow for
condensation drainage

Connection

The system must be installed with mini-
mum air resistance and must be free from
air leakage. Use of flexible pipes must
therefore be kept to a minimum. The pipe
fan connection size is ø124 mm.

General electrical

The unit has a three-position switch as
standard and should be connected accor-
ding to one of the attached wiring dia-
grams (see fig. 5 and 6) with an earth. The
connection must comply with NEN 1010
and the locally applicable regulations. The
connection cable on the version without a
perilex plug should only be connected by
a registered fitter. The connection cable
must then be secured using a pull relief. If
the unit is fitted with a perilex plug, then
this plug may only be inserted in the wall
6 - EN
socket once installation is complete. All
units are fitted with an operating switch
as standard.
The unit is not suited for connec-
tion to three-phase mains.

10. Set-up (valves, fan)

AC version
Close windows and doors. Set the system
to its highest position and open the val-
ves to their maximum. Regulate the valves
to the required flow per room. Record the
set-up position of the valves.
DC version
Close windows and doors. Set the system
to its highest position and open the valves
to their maximum. Measure the total air
volume at the valves. Adjust the system
to the correct total capacity using the
dipswitches. Regulate the valves to the
required flow per room. Tick the position
of the dipswitches in the table.
Record the set-up position of the valves.
Settings dipswitches
The control PCB has some (DIP) switches
with which a number of extra settings can
be set. Using the switches 1 to 4 (see fig.
3), the speed of the fan can be adjusted
further in positions 2 and 3. This might
be necessary if long supply and exhaust
ducts are used.
Switches 5 and 6 (see fig. 3) are used to
set external controls for the ventilation
system.
