WARNING

UNIT DESIGN

AND OPERATING

LOGIC

The unit operates as follows:

Warm stale extract air from the room flows to the unit, where it is filtered, then air flows

through the heat exchanger and is exhausted outside by the extract fan.

Clean cold air from outside is moved by the supply filter.

Then filtered air flows through the heat exchanger and is moved to the room with the

supply fan.

Heat energy of warm extract air is transferred to clean intake fresh air from outside and

warms it up.

The air flows remain fully separated within the heat exchanger.

Heat and energy recovery minimizes heat losses and ensure humidity balance, thus reducing

expenses for heating in the cold seasons and air conditioning in the warm season.

The unit is a frame structure consisting of six 25 mm thick rigidly fixed aluzinc sandwich panels,

internally filled with mineral wool for sound insulation.

The unit components: the quick detachable specially sealed service panels 14 provide

maintenance access; the side casing panels 13 with a terminal box 15 fixed to the outer

surface of one them.

The terminal box incorporates a terminal block (not shown in Fig. 2) with the wires routed

from the circuit control board.

The sealed cable gland is used for routing of power and ground cables from the unit and

connection to the terminal block.

The wiring diagram for connection of the air handling unit is shown on inner side

of the terminal box lid.

VUT EH ECVUT EH EC

The basic unit complete set includes:

- remote-mounted control panel 9 that is connected via the data cable 12 to the integrated

control system in the unit;

- a supply 1 and an extract 2 centrifugal single-intake fans with backward curved blades and

maintenance-free external rotor motors with built-in overheating protection.

- plate counter-flow heat exchanger. It may be temporary replaced with a summer block

for a season requiring no heat recovery.

- one electric air heater. Two integrated thermal switches, one of safety type with response

temperature +50 °C and automatic reset and another of emergency type with response

temperature +90 °C and manual reset.

- supply filter 4 with filter class G4 or F7 and extract filter 5 with filter class G4.

The supply filter prevent ingress of contaminants from the outdoor air to the room and

prevent the unit components from contamination.

The extract air filters protect the unit components from contamination.

The filter replacement warning is shown by the lamp indicator on the control panel.

The filter replacement periodicity is set from 10 up to 99 days on the control panel.

During heat recovery condensate may be generated.

Condensate is collected in the drain pan 11 and flows outside via the drain pipe 6.
