REMKO PWW
Mixed-air box MLK
The mixed-air box MLK is desi-
gned for both wall and ceiling
mounting.
The ratio of fresh air to recirculated
air can be continuously adjusted
manually or with a flap servomotor
(accessory).
With the supplied variable cover,
the direction of the air on the inlet
side can be freely selected.
For operation of the mixed-air box
with flap servomotor, the mixed-
air flaps must be checked regularly
for easy movement and fouling.
Filter box FK
The filter box with pocket filter is
designed for direct mounting on
the units.
The pocket filter can be removed
from the side.
The filter medium of the pocket
filter can be regenerated and has
the filter class G3.
Further filter classes are available
on request.
Filter maintenance
Depending on the operating con-
ditions, the pocket filter must be
checked regularly and cleaned or
replaced if necessary.
Automatic monitoring
The degree of clogging of the
pocket filter can be monitored
via a differential pressure switch
(special accessory).
When the final pressure difference
is reached, the filters must be
replaced with filters with the same
quality class.
Accessory installation
Anti-frost thermostat FS
The anti-frost thermostat is a
precise water temperature sensor,
which can be subsequently moun-
ted on the surface of pipes.
The thermostat is fitted with a
precision sensitive switch.
The supplied strap with clamp

without draining the heating sys-
tem.
Installation
Prior to fitting, the pipe insulation
in the contact area of the sensor
