TABLE OF CONTENTS
1 PURPOSE AND PRINCIPLE OF OPERATION
Destratificator (under ceiling air mixer) co-operates with various devices of the heating system and is used for improving the
efficiency of heating in high objects such as: industrial shops, storehouses, supermarkets, exhibition halls.
The primary function of the under ceiling air mixer is counteracting the accumulation of warm air in upper zones of the room. An axial fan
draws warm air in and forces its flow downwards, i.e. towards the zone occupied by people (the thermal comfort zone). This results in a
reduction of heat losses through the ceiling and causes a faster heating of the building.
Destratificator is designed for installation indoors, in an environment protected against weather conditions and in rooms in which
there is no risk of explosion.

Start Up
Before connecting the power supply check the
correctness of connection of the fan motor and the
controllers. These connections should be executed in
accordance with their technical documentation.
Before connecting the power supply check whether the
mains voltage is in accordance with the voltage on the
device data plate.
The electrical system supplying the fan motor should be
additionally protected with a circuit breaker against the
effects of a possible short-circuit in the system.
Starting the device without connecting the ground
conductor is forbidden.
Operation
The device is designed for operation inside buildings, at
temperatures above 0
o
C.
The device must be inspected periodically. In the case
of incorrect operation of the device it should be switched
off immediately.
It is forbidden to use a damaged device. The
manufacturer bears no responsibility for damage
resulting from the use of a damaged device.
For the time of performing inspection or cleaning the
device, the electrical power supply should be
disconnected.
