KOMFORT EC LB/LBE S11
Fig. 1. Unit design and operating logic
DESIGN
The casing is made of double-skinned aluzinc panels, internally lled
with mineral wool layer 25 mm for heat- and sound-insulation. The casing is
equipped with xing brackets with vibration absorbing connectors for easy
installation. The hinged casing panel ensures easy access to the internals for
cleaning and other maintenance operations.
The spigots for connection to the air ducts are located at the side of the
unit and are rubber sealed for airtight connection to the air ducts. The unit is
tted with a bypass damper which is opened automatically in summer time
to cool down a room with cool outside air. For the model with a heater the
bypass damper is also used for the heat exchanger freezing protection. The
service access is on the side panel which can be installed on the left, seen on
the supply air ow direction.
The unit is equipped with high-ecient external rotor EC motors and
centrifugal impellers.
The forward curved blades in KOMFORT EC LB300/LB400/LBE300/
LBE400 S11 provide permanent air ow. The KOMFORT EC LB600/LBE600
S11 model has impellers with backward curved blades.
EC motors have the best power consumption to air capacity ratio
and meet the latest demands concerning energy saving and high-ecient
ventilation. EC motors are featured with high performance, low noise level
and totally controllable speed range.
The unit is equipped with a high-ecient counter-ow polystyrene heat
exchanger with a large surface area.
Heat recovery is based on utilization of heat energy contained in the
extract air stream for heating up of supply air stream. Extract air transfers
most of its heat to the intake air ow. Heat recovery reduces heat energy
losses in cold seasons. In summer the heat exchanger performs reverse and
transfers a part of the accumulated coolness from the cooled extract air for
warming up of intake air. This contributes to better performance of the air
conditioner in ventilated premises.
The drain pan under the heat exchanger block is used for condensate
collection and drainage. The drain pan is equipped with a drain pipe for
condensate removal outside the unit. The electronic frost protection system
is used to prevent the heat exchanger freezing in cold seasons.
• KOMFORT EC LBE S11: the bypass damper opens on a signal from
the temperature sensor to let intake air ow bypass the heat exchanger.
The heater warms up the supply air temperature up to the set point.
Synchronously, the heat exchanger surface is warmed up with extract air
ow. After a freezing danger is over the bypass closes and the unit reverts to
the normal operation mode.
• KOMFORT EC LB S11: In case of heat exchanger freezing danger
communicated by the external temperature sensor the supply fan is stopped
to let warm extract air warm up the heat exchanger. After that the supply fan
is turned on and the unit reverts to normal operation.
The KOMFORT EC LBE S11 unit is equipped with an electric heater for
operation during cold seasons at low outside temperature. The integrated
electric heater is activated to warm up supply air ow if set indoor air
temperature may not be reached by means of heat recovery only.
The smooth heat output control ensures automatic supply air
temperature maintaining.
Two integrated protection thermostats, one actuated at
+60 °C with automatic restart and the other one actuated at +90 °C with
manual restart are used for overheating protection.
The built-in G4 pocket supply lter and G4 cassette extract lter
provide ecient air ltration. Optionally, a F7 supply lter may be used.

OPERATING LOGIC
Cold fresh air from outside ows into the unit, where it is cleaned in the
supply lter. Then the air ows through the heat exchanger and is moved to
the room with the supply fan.
Warm extract air from the room ows into the unit and is cleaned in
the extract lter. Then the air is moved through the heat exchanger and is
exhausted outside with the extract fan.
Cold intake air is heated in the heat exchanger by the heat energy of
warm and humid extract air. The air ows are fully separated while owing
through the heat exchanger.
Heat recovery minimizes heat losses caused as compared to traditional
window ventilation and saves energy.
In summer the heat exchanger performs reverse and transfers a part
of the accumulated coolness from the cooled extract air for warming up
of intake air. This contributes to better performance of the air conditioner
in ventilated premises.

MOUNTING
!
Safety precautions:
The unit must be mounted to a rigid and stable structure.
The unit must be suspended using anchor bolts. Make sure that the base structure is capable of sustaining the unit weight.
The unit mounting is allowed only after power cut-o and full stop of the rotating parts.
Restrictions:
• Do not operate the unit beyond the determined temperatures, in aggressive and in explosive environment.
• Do not connect the clothes dryer or other similar equipment to the ventilation system.
• Do not use the unit for air/dust mixture handling.
WARNING
The unit can be installed on the oor, suspended to the ceiling or xed to the
wall by means of mounting brackets (Fig. 4).
The unit mounting position must provide condensate drainage and access
to the hinged service panel for electric connection, maintenance and lter
replacement.
The unit is suspended using anchor bolts and threaded dowels.
The unit must be mounted on a plane wall. Mounting of the unit to an uneven
surface can lead to the unit casing distortion and operation disturbance.
The unit mounting position must provide condensate drainage.
While planning the ductwork layout avoid too long air duct sections,
numerous bends and reducers because it may reduce air ow. The mounted air
ducts must not be deformed. Provide airtight connection of the air ducts to the
unit spigots and ttings.
To attain the best performance of the unit and to minimise turbulence-
induced air pressure losses connect the straight air duct section to the spigots
on both sides of the unit while mounting. Minimum straight air duct length:
equal to 1 air duct diameter on intake side,
equal to 3 air duct diameters on outlet side.
If the air ducts are too short or not connected, protect the unit parts from
ingress of foreign objects. To prevent uncontrollable access to the fans the
spigots may be covered with a protecting grille or other protecting device
with mesh width not more than 12.5 mm.
Prior to starting mounting make sure the mounting surface has sucient
load capacity matching the unit weight. Otherwise reinforce the installation
place with beams. To prevent resonance problem use anchor bolts with a
sucient length.
If the spiral air duct connection point is supposed to be the source of
noise generation replace the spiral air duct with a exible one. The exible
connectors are also recommended for noise absorption.
