The unit supplies heated and filtered outdoor air into the room.
The unit uses a frameless centrifugal fan directly driven by an external rotor motor. The fan impeller blades are curved backwards. The
motor has built-in thermal protection and requires no maintenance.
After filtration, the air passes through the block of heaters. The unit automation regulates the power of the heaters in such a manner
so as to maintain the set air temperature at the unit outlet.
The electric heater has double overheating protection.
In case a thermostat with low threshold and automatic return is activated, the heater is turned off and the fan continues to operate, the
air is blown through the unit for a set time, after which the unit is turned off. After the thermostat returns to its initial position, the unit
turns on and continues to operate with the settings active prior to activation of the thermostat. Automatic turn on of the unit is possible
three times in a row within one hour. In case this thermostat activates for the fourth time, the unit will not turn on.
In case a thermostat with high threshold and manual return is activated, the heater is turned off and the unit continues to operate
without being able to turn on the heater. To return the heater to operation, press the manual reset button on the thermostat.
WARNING! Manual restartoftheunitafterahighthresholdthermostathastrippedmustbeperformed byaqualied technician
after the causes of overheating have been eliminated.

IT IS UNSAFE AND IMPOSSIBLE WITHOUT SPECIAL KNOWLEDGE
MOUNTING AND SETUP
Units MPA 300 E EC A30/31/32, MPA 400 E EC A30/31/32, MPA 700 E EC A30/31/32 have spigots for connecting to air ducts with round
cross-section.
Units MPA 1000 E EC A30/31/32, MPA 1500 E EC A30/31/32, MPA 2000 E EC A30/31/32,
MPA 3000 E EC A30/31/32, MPA 4000 E EC A30/31/32 are installed into a system of rectangular air ducts that are connected either
directly to the unit casing or through the side panels.
The units are installed between the ducts, taking into account the direction of air flow, which is indicated by an arrow on the casing.
WARNING!
• To reduce aerodynamic losses related to air flow turbulence, use shaped reducers in order to reduce or increase the cross-section
of air ducts.
• To minimise turbulence-induced air pressure losses, connect the straight air duct sections on both sides of the unit. Minimum
straight air duct length: equal to 1 air duct diameter on intake side and 3 air duct diameters on outlet side
• It is necessary to protect the internal parts of the unit from penetration of foreign objects. For example, install a grill with a cell side
size of no more than 12.5 mm to prevent free access to the fan and foreign objects from entering the unit.
• It is recommended to connect the duct through a flexible connection to reduce noise and vibration transmission. Such connections
allow compensating for possible mounting inaccuracies when connecting the unit to air ducts.
• The equipment and air ducts that are to be connected must have their own mounting bracket in order to avoid transferring their
own weight loads to the unit.
The unit must be mounted so that it can be accessed for service purposes. Enough space must be provided for the cover to open all
the way. After removing the screws, the cover will hang on special cables.
Installation is possible on the ceiling or on the wall in such a way that the air flow is horizontal. In this case, the control unit can be
located both above and below.
The mounting is carried out at 4 points with mounting brackets. It is recommended to use anchor threaded rods with nuts for fastening
the unit. The vibration mounts on the unit casing must fit snugly against the ceiling or wall surface.
Fasteners for the unit mounting are not included into delivery set and should be ordered separately. While choosing fasteners consider
the material of the mounting surface and the unit weight. For selection of the fasteners for unit mounting please refer to a service
technician.
Install the outdoor temperature sensor in the air duct downstream of the unit along the air flow.
the units are available in the right- or left-side versions depending on the location of the control unit relative to the air flow direction. The
unit is designed so that the control unit can be moved to the opposite side of the casing. This allows for a more rational placement of
the equipment when installing the ventilation system.
