DESIGN AND OPERATING LOGIC
MPA W / MPA W LCD are the complete air supply units which ensure ltering, pre-heating and supply of fresh outdoor air into
the serviced spaces. The units t rectangular air ducts with nominal size of 400x200, 500x250, 500x300, 600x300, 600x350 and
800x500 mm.
The steel casing has a protective aluzinc coating and a 25 mm mineral wool layer for heat and sound insulation.
The built-in G4 lter ensures high-quality purication of the supply air.
During the winter time and the o-season the supply air is pre-heated by means of a water (glycol) heater. The water heaters are
rated for maximum operating pressure of 1.0 MPa (10 bar) and maximum heat medium temperature of +95 °C.
The air supply unit features a double-inlet type centrifugal fan with forward bent blades and a built-in protection thermostat
which restarts automatically. The electric motor and impeller of the fan undergo two-plane dynamic balancing. The ball bearings
of the electric motor are completely maintenance-free with a minimum service life of 40,000 hours.
MPA ... W LCD features an automatic control system (ACS). The ACS provides comprehensive control of the air supply unit and
adjustment of the vital parameters of ventilation and air conditioning systems. The control units of MPA 800 W LCD ... 2500 W LCD
series units are housed in plastic casings while those of the MPA 3200 W LCD ... MPA 5000 W LCD series units have metal casings.
The control unit casing incorporates automatic equipment circuit board as well as control and protective elements of the power
components.

MOUNTING AND SETUP
DISCONNECT THE UNIT FROM THE POWER SUPPLY PRIOR TO ANY OPERATIONS.
THE ELECTRIC MAINS CONNECTION MUST BE PERFORMED BY A PROFESSIONAL
ELECTRICIAN. THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE STATED ON THE
MANUFACTURER’S LABEL.
THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED AND
HAVING THE REQUIRED TOOLS AND MATERIALS.
The unit must be installed in such a way so that the direction of the arrow shown on the lid matches the direction of air flow in
the system. The unit mounting locations must enable adequate access to the removable lid for maintenance, technical service and
replacement operations.
The unit can be mounted or suspended with threaded rods. The air supply unit must be secured in such a way so as to entirely
prevent its disconnection or collapse (in consideration of the unit weight and the mating surface material) using all the available
L-shaped support brackets with vibration dampers attached to the air supply unit base.
V38EN-02.indd 9 29.07.2015 16:03:46

10
The air supply unit is designed to fit rectangular air ducts.
To avoid noise transfer and accidental vibrational motion the air ducts should be connected via a exible insert.
The mounting dimensions of the mated air duct must match those of the air supply unit.
To maximise the unit performance and reduce the aerodynamic losses due to air ow turbulence the unit should be preceded
and followed by straight duct sections.
Minimum recommended straight section length:
1 air duct diameter on the intake side (or at least one diagonal of the air channel section for a rectangular duct);
3 diameters on the exhaust side (or at least three diagonals of the air duct section for a rectangular duct). If the air ducts on
one or several unit pipe ttings are not available or too short the unit internals must be covered with a protective grille or
other similar device with a minimum cell size of 12.5 mm restricting access to the fan to prevent any foreign objects.
TE1 outdoor temperature sensor installation
The air supply unit is equipped with an external temperature sensor.
1. Undo the two screws securing the sensor cover.
2. Remove the sensor cover.
3. Install the sensor on the outside surface of the wall. The wall must not be subject to direct sunlight.
4. Re-install the sensor cover.
5. Connect the sensor to terminal block X1 according to the external wiring diagram.

The supply air temperature sensor TE5 is installed downstream of the water heater (along the air flow stream) and provides
supply air temperature regulation.
The filter pressure switch PD1 is installed in such a way that the relay negative input (-) is placed in the lower pressure area
(i.e. downstream of the filter along the air stream) by means of a tube whereas the positive input (+) - in the higher pressure area
(i.e. upstream of the filter along the air stream). The pressure differential value on the pressure switch must correspond to the
maximum pressure differential on a contaminated filter (250 Pa).
CONNECTION TO ELECTRIC MAINS
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL
VOID THE WARRANTY.
The air supply unit is designed for an AC electric mains:
• 230 V / 50 Hz single-phase for MPA 800 W ... 2500 W / MPA 800 W ... 2500 W LCD;
• 400 W / 50 Hz three-phase for MPA 3200 W ... 5000 W / MPA 3200 W ... 5000 W LCD.
The unit connection must be made using durable, insulated and heat-resistant conductors (cables and wires) with the minimum
section of 1 mm2. The conductors are routed to the terminal box and the control unit through sealed lead-ins. The air supply unit
is connected to the electric mains via an automatic cut-out switch with a magnetic breaker built into the stationary wiring. The
minimum cut-out switch trip current must higher than the rated current consumption of the unit. The QF external switch location
must ensure free access for quick shutdown of the air supply unit. The protection trip current must be consistent with the current
consumption of the air supply unit.
MPA ... W air supply units are connected via terminal block X1 inside the terminal box in accordance with the terminal
designations given inside the terminal box and the connections diagram:
