1. INTENDED USE
TERM-E heating and ventilation units, are intended to heat and ventilate such compartment as:
industrial halls, warehouses, workshops, other objects of similar use
The units should be used only according to the intended use.
The manufacturer is not liable for using the units against the intended use and for any
damages arisen for this reason.
TERM 1; 2; 3 and 4 units cannot be used in the compartments with relative humidity
larger than 95% and air dust concentration over 3mg/m3.
The compartment can be served by one or larger number of the units, also by the units of different
sizes. The units can operate as heating or heating and ventilation units with added intake boxes and
wall or roof intakes. The intake boxes enable to draw circulating air through grids located on either
side of the box and fresh air through an inlet hole of the intake box.
2. DESIGNATIONS

3. DEVICE DESCRIPTION
W skład aparatu wchodzą:
»axial fan mounted on the rear wall of the unit with a net protecting the rotor;
»electric heaters with spirally rolled aluminium nned tubes;
»casing made of steel sheets with a single-row outlet grid allowing adjusting a direction of supply
air. The structure of grid blades protects against an automatic rearrangement of the blades.
The single-row grid can be replaced with the slot diffuser or outlet nozzle.
The casing can be made of stainless steel sheets.
»protection net made of galvanized steel sheet against accidental contact with heaters,
The casing variant with the following items is recommended to use with the units which are planned
to be operated as ceilings ones:
»slot diffuser - for heating a zone of human presence by a secondary air stream;
»discharge cone - for increasing a range of supply air stream.

The units are supplied with the single-row grid as a standard.
Grids have the movable blades enabling the air stream direction and reach adjustment.
Ceiling units can be equipped with:
»slot diffusers (N) (air supply to 4 sides);
»discharge cone (D).
Wall units can be also equipped with discharge cone (D).
Slot diffusers are enabling heating people staying zones with the secondary air stream.
Unit TERM-E with slot diffuser can be suspended on the height max. 4m.
Discharge cone enable increase of air supply range.

5. ADDITIONAL EQUIPMENT
ROOF INTAKE CD
The roof intakes are intended to draw fresh air from above the roof and to protect the object against
precipitation.
In order to protect against pollution and insects the intakes have shields and nets installed on either
side (only for CD-4 and amount of external air over 40% the intake has the shields installed on four
sides).
The intakes are adapted to connect with the roof bases PD.

INTAKE BOXES SC
For ceiling and wall heating and ventilation units
Basic version
Version with additional elements:
lter and circulating air dampers
The intake boxes are used to draw and mix fresh and circulating air.
In case the intake boxes are used for the TERM units it is necessary to use (as additional equipment)
exible connector (K) allowing connecting the intake boxes with the units.
9www.juwent.com.pl
In basic version the intake boxes SC consists of:
»fresh air damper;
»mixing chamber with circulating air inlet grids.
The fresh air damper is operated a actuator.
The mixing chamber has 2 grids (manually adjusted) in the circulating air inlet holes allowing setting
a share of circulating air in the total air efciency.

The intake boxes SC can be made with additional elements:
»lter (F) class G3;
»circulating air dampers (P) with actuators.
The intake boxes with additional elements are made in consultation with the manufacturer.
In consultation with the manufacturer the intake boxes can be also made with the mixing chamber
with one circulating air inlet grid.

Thermal power of the units with SC intake boxes in the standard version is decreased by about~5%.
ADJUSTMENT RANGES OF INTAKE BOXES SC IN STANDARD VERSION
The intake boxes SC in standard version are delivered for all TERM units with a constant recommended
circulating air grid closing angle equal to 60O.

When it is required to extend the adjustment of share from 100% of fresh air to 100 % of circulating
air it is foreseen to replace the standard intake boxes with circulating air grids with the boxes with
increased tightness dampers (2 pcs.) with servomotors.

The TERM-E1 units can operate totally using fresh air from the wall intakes with dimensions equal to
dimensions of cross-sections of intake boxes.
6. TRANSPORT
The delivered units are completely assembled, protected from outside by polyethylene foil against
pollution and weather impacts.
The Product Manual is delivered along with the unit.
The intake boxes and wall intakes constitute additional equipment and they are delivered separately,
protected by polyethylene foil.
The automatics elements delivered at the customer’s request are packed separately.
The units should be transported in one layer in a way preventing mechanical damages.
7. SAFETY RECOMMENDATIONS
The heating and ventilation units should be used only in compliance with the instruction
manual.
The start-up, mounting, connection, inspections and repairs of the unit should be
executed by an authorized installer, the electric works should be executed by a person
having required certicates authorized to carry out electric works.
All service and repair works should be executed when voltage is off.
Unit should be protected against moisture and do not clean the heater with a damp
cloth.
Unit can only be operated when it is fully operational, in the event of a failure,
immediately cut off the power supply.
