INTRODUCTION

The present User’s Manual contains the technical details, operating instructions and technical specifi cation for DRF-OV and DRFI-OV destratifi cator.

USE

A destratifi cator is a device intended to minimize the heat loss by cancelling the temperature diff erential on the premises. destratifi cators are essential elements of energy-saving solutions for buildings and premises.

Such units are used to force the warm air accumulated under the ceiling toward the lower part of the space. By ensuring an even temperature in the entire space a destratifi cator helps to reduce the heating costs. In the warm season destratifi cators are used to supply fresh air into a specifi c zone thus creating a favorable microclimate in the ventilated area.

The destratifi cator is designed for continuous operation without disconnection from the power mains.

The air being handled must not contain any combustible or explosive mixtures, chemical fumes, sticky substances, fi brous materials, coarse dust, soot, fat or any environment prolifi c for the formation of harmful substances (toxic substances, dust and pathogens).

5

THE DESTRATIFICATOR IS NOT INTENDED FOR OPERATION BY CHILDREN OR ANY PERSONS WITH LIMITED SENSORY

OR MENTAL CAPACITY AS WELL PERSONS LACKING THE REQUIRED TRAINING.

THE DESTRATIFICATOR MUST BE HANDLED ONLY BY PROPERLY QUALIFIED PERSONNEL AFTER THE APPROPRIATE

SAFETY BRIEFING.

THE CHOICE OF DESTRATIFICATOR INSTALLATION LOCATION MUST PREVENT UNAUTHORIZED ACCESS BY

UNATTENDED.

DESIGN AND OPERATING LOGIC

The destratifi cator (see Fig. 2) consists of an axial fan attached to the casing via the vibration mounts. The destratifi cator has a polymercoated steel casing.

The destratifi cator is equipped with a single-phase asynchronous motors with an external rotor and an axial impeller. The motor is equipped with built-in thermal protection enabling its automatic restarting and utilizes rolling-element bearings. The motor protection class is IP 44.

The DRFI-OV casing has special perforation and a sound-insulating layer of mineral wool to reduce the noise generated by the axial fan. The DRFI-OV destratifi cator has a fl ow straightener at the dicharge which ensures direct air fl ow and maximum air throw distance.

The destratifi cator is mounted by means of the bow bracket (DRFI-OV can be fi xed with 15° steps) as well as the mounting and the safety cables with threaded joints each 3 m long.

MOUNTING AND SET-UP

Having unpacked the destratifi cator and prior to installation:

Read the User's Operation Manual carefully;

Check for signs of transit damage;

Manually check the impeller for smooth rotation.

Check the load-bearing structures at the installation site for adequate strength.

Follow the safety regulations during the make-ready procedures and destratifi cator operation.

Installation:

The destratifi cator is designed for installation on premises protected against atmospheric phenomena. The unit is installed under the ceiling of the premises with the airfl ow nozzle down.

The destratifi cator is intended to be rigidly mounted to the load-bearing structure or suspended by means of the mounting kit

(included in the delivery package). Mounting the destratifi cator on two two cables allows the additional benefi t of unit angle correction by adjusting the safety cable length.

Attach the destratifi cator by the bow bracket;

Secure the destratifi cator to the threaded bar with 2 nuts (see Fig. 3.1);

Avoid deformation of the destratifi cator elements during installation;

Attach one end of the safety cable to the building structures;

Attach the other end of the safety cable to the destratifi cator bracket (Fig. 3.2);

8

Loosen the fastening bolts between the destratifi cator and the bracket, turn the destratifi cator and direct its nozzle toward the intended air supply area (see Fig. 3.3);

Tighten the bolts between the casing and the bracket.

CONNECTION TO POWER MAINS

9

THE DESTRATIFICATOR MUST BE CONNECTED TO THE POWER MAINS ONLY BY QUALIFIED PERSONS HAVING

BEEN MADE FAMILIAR WITH THE PRESENT OPERATION MANUAL.

THE UNIT IS INTENDED FOR CONNECTION TO AC MAINS SUPPLYING THE VOLTAGE COMPLIANT WITH THE

TECHNICAL SPECIFICATION CHART.

CHECK THE ENTIRE POWER CORD LENGTH FOR CHOKING. DO NOT SWITCH ON THE DESTRATIFICATOR IF THE

POWER CORD IS DAMAGED.

DISCONNECT THE DESTRATIFICATOR FROM THE POWER SUPPLY PRIOR TO ANY WORK ON THE UNIT! THE

NOMINAL ELECTRICAL PARAMETERS OF THE DESTRATIFICATOR ARE GIVEN ON THE MANUFACTURER’S LABEL.

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

The destratifi cator is intended for connection to a single-phase 230 V/50 Hz AC mains.

The destratifi cator connection must be made using durable, insulated and heat-resistant conductors (cables and wires). The external lead-in (230V/50Hz) must be equipped with an automatic cutout switch built into the stationary wiring to disconnect all the mains phases.

The QF external switch position (see Fig. 4) must ensure free access for quick power-off of the unit.

The recommended automatic switch nominal current is 1.0 A. The wire section is 0.75 mm². 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 destratifi cator connections are made on the X1 terminal block mounted inside the terminal box on the destratifi cator casing in strict accordance with the electrical connection diagram (see Fig. 4). 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 destratifi cators 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 destratifi cator 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.
