PURPOSE

Due to the ability to save heating energy by means of energy recovery the unit is an important element of energy-efficient premises.

The unit is a component part and is not designed for stand-alone operation.

The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafés, conference halls and other utility and public spaces

as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream of supply air.

THE UNIT MAY NOT BE OPERATED BY CHILDREN OR PERSONS WITH REDUCED PHYSICAL,

MENTAL OR SENSORY CAPACITIES, OR LACKING THE APPROPRIATE TRAINING.

THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED PERSONNEL

AFTER THE APPROPRIATE BRIEFING.

THE CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT UNAUTHORIZED ACCESS BY

UNATTENDED CHILDREN.

Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials, coarse dust, soot

and oil particles or environments favourable for the formation of hazardous substances (toxic substances, dust, pathogenic germs).

The service side of the unit is equipped with a detachable access door with manual bolts for cleaning or replacement of the filters and heat exchanger.

The plate enthalpy cross-flow heat exchanger is made of polymerized cellulose. The control unit is positioned inside the unit casing. The power and the

ground cable are to connect to the control unit through the airtight electric lead-in in the unit casing side. The unit is equipped with a speed controller

and the Euro Plug XP.

UNIT OPERATION MODES

Heat recovery: warm extract air from the room flows into the unit and is cleaned in the extract filter. Then the air is moved through the heat exchanger

and is exhausted outside with the extract fan.

Cold fresh air from outside flows into the unit, where it is cleaned in the supply filter. Then the air flows through the heat exchanger and is moved to

the room with the supply fan.

Supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. The air flows are fully

separated while flowing through the heat exchanger. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season.

The enthalpy heat exchanger allows to recover humidity as well as heat.

In the summer period, the supplied fresh air is cooled and dried by the heat exchanger, in the winter period it is heated and moisturized. The water

vapour is devaporated from the stale wet air and absorbed with heat exchanger plates. The released heat and moisture are transferred to the supply air.

The transferring of dirt, odours and microorganisms from one air flow to another is excluded.

SUPPLY AIR

EXHAUST AIR

Defrosting mode: to prevent the heat exchanger freezing in the cold season the unit is equipped with a thermostat in the exhaust air duct downstream

of the heat exchanger. The unit switches to the defrosting mode at the extract air temperature +3 °C. As the temperature rises the unit returns to the

previous mode. In the Defrosting mode the supply fan is turned off and the heat exchanger is warmed up with warm extract air flow.

To set the thermostat temperature threshold turn the control knob to the according position. The recommended thermostat operating temperature is

+3 °C (factory setting).

MOUNTING AND SETUP

THE UNIT MUST BE MOUNTED BY A QUALIFIED EXPERT ONLY, PROPERLY TRAINED AND

HAVING THE REQUIRED TOOLS AND MATERIALS.

The unit is designed for ceiling mounting with anchor threaded bolts, nuts and vibration-absorbing rubber. Fasteners for unit mounting are not included

in the delivery set and should be ordered separately. While choosing fasteners consider the material of the mounting surface as well as the weigh of the

unit, refer to the Technical Data section. Fasteners for unit mounting should be selected by the service technician.

Before mounting make sure that the casing is free of any foreign objects like film or paper. While installing the unit ensure convenient access for

subsequent maintenance and repair.

Minimum required distance from the unit to the ceiling is 20 mm.

To attain the best performance of the unit and to minimise turbulence-induced air pressure losses connect the straight air duct section to the spigots

on both sides of the unit while mounting.

Minimum straight air duct length:

• equal to 1 air duct diameter on intake side

• equal to 3 air duct diameters on outlet side

If the air ducts are too short or not connected, protect the unit parts from ingress of foreign objects. To prevent uncontrollable access to the fans the

spigots may be covered with a protecting grille or other protecting device with mesh width not more than 12.5 mm.

CONNECTION TO POWER MAINS

DISCONNECT THE UNIT FROM POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.

INSTALLATION SHALL ONLY BE PERFORMED BY A PROFESSIONAL ELECTRICIAN QUALIFIED FOR

UNASSISTED OPERATIONS WITH ELECTRICAL INSTALLATIONS UP TO 1000 V AFTER CAREFUL STUDY

OF THE PRESENT USER’S MANUAL.

THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL.

ANY INTERNAL CONNECTION MODIFICATIONS ARE NOT ALLOWED AND RESULT IN WARRANTY LOSS.

The unit is rated for connection to single-phase ac 230 V / 50 Hz.

Connect the unit to power mains using the pre-wired power cord with the Euro Plug XP. Connection is made through the external automatic circuit

breaker with magnetic trip integrated into the fixed wiring system. The position of the automatic circuit breaker must ensure free access for quick

power-off of the unit. The trip current must be not less than the consumption current, refer to Technical data.

The speed controller is connected to the unit be the manufacturer using the cable of 3 m length. The reconnection of the controller is allowed if the cable

length needs to be changed. Technical requirements to a cable: type – 2x0.5 mm2, length – up to 10 m.

To access the control unit, remove the mounting screws of the service side panel of the unit and take it off.
