DESIGNATION KEY

TECHNICAL DATA

The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to 80 % without condensation.
The unit should be operated continuously, and in cases where ventilation is not necessary, reduce the air flow of the fans to a minimum (20%). This will ensure a favorable indoor climate and reduce the amount of condensation inside the unit, which can damage electronic components. Never use the unit for dehumidification, for example, of new buildings.
The unit is rated as a Class I electrical appliance.
Hazardous parts access and water ingress protection rating:
IP22 for the unit connected to the air ducts
IP44 for the unit motors
The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.

THE OVERALL AND CONNECTION DIMENSIONS OF MPA UNIT 

MAIN TECHNICAL PARAMETERS 

DESIGN AND OPERATING PRINCIPLE

The unit allows controlling the air flow, air temperature (preheating) and air filtering.

• Air flow can be adjusted by controlling the fan speed.
• Air heating is provided by an integrated electric heater (item 2).
• The unit is equipped with an air filter with filtering class G4 (item З).
• Hinged (item 4) or removable cover optimally uses the space for installation.
• Unit design allows standard connection to rectangular air ducts of the duct work.
• The unit is equipped with two sensors-thermal switches: one is a safety thermal switch with automatic restart, and the second one is an emergency thermal switch with manual restart when the RESET button is pressed (pos. 5).

MOUNTING AND SET-UP

READ THE USER’S MANUAL PRIOR TO MOUNTING THE UNIT.

The unit should be mounted so that the arrow on the cover coincides with air flow direction in the system in order to provide access for maintenance, servicing or replacement work.
Enough space must be provided for the cover to open all the way.
The unit can be mounted on flat surface or suspended on a threaded rod ensuring a secure fixation to prevent unit detachment or falling down (in consideration of the unit weight and the mating surface material) using all the available L-shaped support brackets with an antivibration damper attached to the unit base.
The unit is designed for mounting into rectangular air ducts.

• The duct should be connected via a flexible connection to eliminate transfer of noise and random vibrations.
• The dimensions of the connected air duct must be the same as the dimensions of the hole in the unit.

The recommended distance between the unit and other elements of the system must be not less than the diagonal of the unit spigot (the distance from corner to corner of its air duct part).

CONNECTION TO POWER MAINS

DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY OPERATIONS. THE UNIT MUST BE CONNECTED TO POWER MAINS BY A QUALIFIED ELECTRICIAN. THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.

ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.

• The unit is rated for connection to 1~220-240 V/50 (60) Hz or 3~400 V/50 Hz power mains according to the wiring diagram.
• The connection must be made using durable, insulated and heat esistant conductors (cables, wires). The conductor crosssection selection shall be based on maximum permissible current and maximum permissible wire heating, which depends on its type, insulation, length and installation method.
• The external power input must be equipped with an automatic circuit breaker QF built into the stationary wiring to open the circuit in the event of overload or short-circuit. The position of the external automatic circuit breaker must ensure free access for quick power-off of the unit. The automatic circuit breaker nominal current must exceed the ventilator current consumption, see the Technical data section or the unit label. It is recommended to select the nominal current of the circuit breaker from the standard series, following the maximum current of the connected unit. The circuit breaker is not included in the delivery set and can be ordered separately.

QF – external circuit breaker
XI – terminal block for connecting the wires of the power supply network, as well as external devices – sensors, damper actuator, control panel, etc.

The automatic circuit breaker location must ensure free access for quick shutdown of the unit.
The required number of wires, their cross-section (mm²), as well as the ratings of the circuit breakers are shown in the table.

The wire cross sections given in the table are for reference only!
Their selection shall be based on maximum permissible wire heating, which depends on its type, insulation, maximum permissible current, length of the lead wire and its location (air, wall).

Additional options for external connections through the X5 terminal block are provided:

• connecting a contact of the automatic fire extinguishing system (inscription on the label – «PK1»)
• connecting a humidity sensor contact – humidistat (inscription on the label – «H1»)
• connecting a three-position air damper (inscription on the label – «1», «2», «3»).

When connecting the contact of the automatic fire extinguishing system, remove the jumper between the X5:1 and X5:2 terminals of the X5 terminal block. In this case, a normally closed «dry contact» is used, which when triggered in case of fire, opens the unit control circuit from the fire alarm panel and de-energizes it.
The humidistat is connected to the X5:3 and X5:4 terminals of the X5 terminal block. Normally open «dry contact» is used. When it is closed, the unit switches to maximum speed.
The air damper actuator is connected to the X5:5, X5:6, and X5:7 terminals; «M» (1) contact of the damper actuator – to the X5:5 terminal (inscription on the sticker «1»); «L» (2) contact – to the X5:6 terminal (inscription «2»); «L» (3) contact – to the Х5:7 terminal (inscription «3»).
The recommended type of damper is KRA (for round or rectangular air ducts) with an LM 230 A actuator (Belimo).

UNIT CONTROL

The unit is controlled using a remote control panel.

FUNCTIONAL CAPABILITIES 

The system allows you to control the performance of the supply fan and has 3 speed levels:

1. minimal ventilation, used on weekends and holidays in non residential premises or at night in residential premises
2. normal ventilation
3. increased ventilation when additional air flow is required

The device has the function of maintaining air temperature by a duct sensor or by a sensor in the control panel.
The duct temperature sensor enables the system to select the most suitable operation mode of the electric heating elements for maintaining a pre-set air temperature in the air duct.
The control panel is also equipped with a temperature sensor thereby allowing the maintenance of the set (user-defined) indoor temperature at the selected fan speed.
The optimal energy-saving program calculates the heater power required to sustain the indoor temperature with up to 1 °C accuracy while adjusting the heater power with up to 1 % accuracy.
The system status monitoring program monitors the unit operating parameters and, in the event of dangerous situations (overheating of the heating elements, critical filter clogging, communication line break), initiates emergency shutdown and sends corresponding signals to the control panel.

STORAGE AND TRANSPORTATION REGULATIONS
