CONNECTION TO POWER MAINS
DISCONNECT THE UNIT FROM POWER SUPPLY PRIOR TO ANY ELECTRIC INSTALLATION
OPERATIONS.
THE POWER MAINS CONNECTION SHALL ONLY BE PERFORMED BY QUALIFIED
PERSONNEL AFTER CAREFUL READING OF THE USER’S MANUAL.
CONNECT THE UNIT TO AN AC POWER SUPPLY WITH THE VOLTAGE CORRESPONDING
TO THE VALUE SPECIFIED IN THE TABLE OF TECHNICAL DATA. CHECK THE ENTIRE POWER
CORD LENGTH FOR CHOKING. DO NOT SWITCH ON THE UNIT IF THE CABLE IS DAMAGED.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE SHOWN ON THE RATING
PLATE. ANY INTERNAL CONNECTION MODIFICATIONS ARE NOT ALLOWED AND RESULT
IN WARRANTY LOSS.
The destratificator is intended for connection to a single-phase 230 V/50 Hz AC mains.
The destratificator is intended for connection to a single-phase 230 V/50 Hz AC mains. The destratificator connection must be
made using durable, insulated and heat-resistant conductors (cables and wires). The external lead-in (230 V/50 Hz) must be equipped
with a circuit breaker built into the stationary wiring to disconnect all the mains phases. The QF external circuit breaker position must
ensure free access for quick power-off of the unit.
The recommended circuit breaker nominal current is 1.0 A. The conductor section is 0.75 mm
2
. However, the conductor selection
shall be based on the maximum permissible wire heating depending on the wire type, its insulation, length and installation method
(i.e. overhead, in pipes or inside the walls).
The destratificator connections are made on the X1 terminal block mounted inside the terminal box on the casing of the
destratificator. The electrical connections diagram sticker is located inside the terminal box.
The speed adjustment (continuous and stepped) is performed by means of a thyristor or autotransformer speed regulator. The
same regulator device can be used for connecting several destratificators simultaneously provided that their combined capacity and
working current remain within the nominal parameters of the speed regulator.

TECHNICAL MAINTENANCE
The technical maintenance and repair of the destratificator may commence only after its disconnection from the power mains and
all the rotating parts coming to a complete halt.
The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.
The recommended annual maintenance should include:
•
Checking the tightness of the fastening bolts and their tightening, if necessary;
•
Checking the fan blades for contamination and their cleaning, if necessary.
