SAFETY REQUIREMENTS
Connection to the mains must be made through a disconnecting device, which is integrated
into the fixed wiring system in accordance with the wiring rules for design of electrical units,
and has a contact separation in all poles that allows for full disconnection under overvoltage
category III conditions.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or
similarly qualified persons in order to avoid a safety hazard.
Ensure that the unit is switched off from the supply mains before removing the guard.
WARNING: If there are any unusual oscillating movements, immediately stop using the unit and
contact the manufacturer, its service agent or suitably qualified persons.
The replacement of parts of the safety suspension system device shall be performed by the
manufacturer, its service agent or suitably qualified persons.
CAUTION: In order to avoid a safety hazard due to inadvertent resetting of the thermal cut-
out, this unit must not be supplied through an external switching device, such as a timer, or
connected to a circuit that is regularly switched on and off by the utility.
Precautions must be taken to avoid the back-flow of gases into the room from the open flue of
gas or other fuel-burning appliances.
The appliance may adversely affect the safe operation of appliances burning gas or other
fuels (including those in other rooms) due to back flow of combustion gases. These gases can
potentially result in carbon monoxide poisoning. After installation of the unit the operation
of flued gas appliances should be tested by a competent person to ensure that back flow of
combustion gases does not occur.
This unit is not intended for use by persons (including children) with reduced physical, sensory
or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the unit by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the unit.
This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved.
Cleaning and user maintenance shall not be made by children without supervision.
Children shall not play with the appliance.
This appliance incorporates an earth connection for functional purposes.

DESIGN AND OPERATING PRINCIPLE
Technical specifications of the particular model are indicated on the unit casing.
The unit is housed in a sound-insulated galvanized steel casing (item 1). The unit casing has 4 mounting brackets with anti-
vibration connectors for ceiling or wall mounting (item 5).
The air flow direction is indicated by the arrow on the fan casing.
The bottom side of the casing is covered with a removable cover (item 2), which is secured with 4 screws (item 4).
A control unit (item 3) is installed on the casing. The power and control cables are pulled through cable glands (item 6). There is also a
pressure drop relay on the unit casing that activates when the pressure drop at the filter increases (item 8).
Models 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 supplied without the side panels (item 7) and are intended for installation
directly into a rectangular air duct. Side panels (ordered separately) allow connecting the unit to air ducts through flexible inserts.
For ease of electrical connection, the units can be ordered with the control unit located either on right or left side of the casing (right- and
left-side versions, respectively, as indicated in the «Designation key» section).
If necessary, the control unit can be moved to the other side of the unit casing before being installed in the ventilation system.
