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 constitute additional equipment and they are delivered separately at the customer’s
request.
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
Solutions minimizing a possibility of hazard to persons and property were applied when
designing and manufacturing the units. However, it does not eliminate all possible risks.
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 certicates authorized to carry out electric works.
All service and repair works should be executed when voltage is off.
In case of the unit failure it is necessary to switch off the power supply to the electric
motor of the fan and close the heating medium supply to the heater immediately.
The unit can be used only when electric safety devices operate correctly.
It must be permanently connected to the electric installation equipped with protective
(earth) terminal, residual current device and service switch.
It is necessary to pay attention not to change the protection lead to the power lead.
The operation of the unit with the fan without a protective net is forbidden.
The heaters of the units can be supplied with water or steam of very high temperature
(up to 160OC) what forces the users to be particularly carful.
A correct selection of ttings (including drain valves) by the designer of the installation
is a condition of safe operation of the steam heater.
Only original spare parts should be used.
Note for the user! The mounting or use of the heating and ventilation unit against the
instruction manual makes the threat of unit damage, creates the hazard to persons and
property and causes the loss of warranty.

9www.juwent.com.pl
Due to the structure the unit does not emit harmful radiation.
Although the unit was designed and manufactured in compliance with the requirements of the
standards, according to their state at the moment of production launch, a probability of injury or
health loss when using the unit is not to be avoided. This probability is connected with a frequency of
access to the unit in the course of its use, cleaning or repair, presence of persons within a dangerous
zone, acting against the safety rules specied in the instruction manual.
The gravity of body injury or deterioration of health condition depends on many factors that often
can be foreseen only partially, taking them into consideration in the structure of the unit, specifying
them and warning against them in the instruction manual.
Therefore there is a residual risk when the operator does not observe the recommendations and
guidelines included in the instruction manual.
8. MOUNTING
Hanging of the unit
For hanging the unit on the construction columns the catches are used (3 pcs) located at the rear
of the casing.

UGW/D-10 240 28 760
UGW/D-11 345 28 1030
UGW/D-12 545 28 1180
Minimal distance of the heating unit from construction partitions at the unit sides is ~ 30 cm.
Hanging the units with intake boxes
Intake boxes should be screwed to the unit, the unit hanged on the wall and the intake box ange
screwed to the wall.
9. WATER INSTALLATION
Unit supply could be from top or lower spout. In new installations, better results are obtained with
lower spout supply due to the heater venting easier.
It is recommended:
»to use cut-off valves upstream and downstream the unit to enable its dismounting without
the necessity to drain the supply installation
»installation of the valve (recommended by Juwent) on medium supply spout.
The venting and draining of the heaters of the units is foreseen centrally in the network.
The vents and drain valves located in the installation outside the unit should be used.
The imprecise venting of the heater can be a reason for which the unit does not reach
planned parameters.
The weight of installation pipes should not rest on the spouts of the heater.

10 www.juwent.com.pl
When connecting the heater to the heating network the spouts of the heater should be protected
against breaking in a way presented in the picture.
The heater damages arisen for the afore-mentioned reason are not covered by the
warranty.
10. STEAM INSTALLATION
The steam heaters should be supplied from the top.
A correct selection of ttings (including drain valves) by the designer of the installation
is a condition of safe operation of the steam heater.
11. ELECTRICAL INSTALLATION
The electric installation and the connection of power to the unit must be executed
according to the relevant requirements of the standards and construction regulations.
The electric connections, start-up, inspections and electric repairs may be executed only
by an electrician who has required certicates to carry electric works and got acquainted
with the instruction manual.
Before the connection it is necessary to make sure whether the voltage value and power
system frequency are compliant with the data specied on the rating plates of the units.
In case of noncompliance the unit should not be connected.
The units are equipped with single (1~230 V/50 Hz) or three-phase (3~400 V/50 Hz). The units should
be powered from the main switchboard equipped with a main switch, differential protection device,
protective (earth) terminal and overload and short-circuit protection devices (motor switches). The
setup of overload protection cannot be higher than rated current of the motor (specied on the
rating plate of the motor of the unit).
The lack of required motor safety devices and non-connection of thermal contact TK to
the control circuit cause the loss of warranty.
The lead powering the motor of the fan should be inserted to the terminal box and fastened to the
protective supports by means of clamp bands.
Electrical connection of the motor must comply with the wiring diagrams placed in the terminal box.
Examples of wiring diagrams and control devices are given in Figures 1, 2 and 3.

12. AUTOMATICS
We can deliver for the units:
Supply and control boxes
The supply and control boxes (equipped with a main switch, overcurrent circuit breakers, short-
circuit protection devices, signalling lamps) are intended to cooperate and control the elements of
automatics, as above.
One control box allows controlling a group of the units by means of single thermostat.
The single (1~230V/50Hz) or three-phase (3~400V/50Hz) power supply of the supply and control
box should be from the main switchboard equipped with a main switch and differential protection
device.
When the automatics are ordered with the unit the electric diagrams of the unit and automatics are
delivered by the company as well.

13www.juwent.com.pl

Valve servomotors
The servomotors that allow controlling the valves “continuous-0÷10V DC” (by means of controller
RT) or “on-off” (by means of thermostat TP or TPP) are used for a direct installation on the valves.
Therefore a position (protrusion) of the servomotor stem is proportional to the value of control
signal from the controller or thermostat.

Room thermostat
A room thermostat (on-off) TP allows setting the required temperature in the room within the
range of 8...30OC by means of a knob, however, the room thermostat (on-off) TPP allows setting the
required temperature in the room within the range of 8...35OC in the day and night mode on the
liquid-crystal display.
The loss of temperature in the room below the set value causes that the thermostat applies a signal
to open the valves and switches on the fan. However, if the temperature in the room exceeds the set
value then the thermostat toggles itself applying a signal to close the valves and switches off the fan.
The thermostat can be used in the circulating and external air system.

Antifreeze thermostat
The heater protection system against freezing (antifreeze thermostat) is a recommended part of the
control system in the heating and ventilation units with the water heaters operating in the external
air system.
The thermostat has a capillary evenly unrolled along the eld of the heater that – after the reduction
of the air temperature (even on a short section of the capillary) below the boundary temperature
(5OC) – transmits a signal to the supply and control box which – to the thermostat response –
signalises the alarm state by the lamp “HEATER ALARM”, switches off the fan, closes the external
air throttle and opens completely the heating water valve of the heater. The system returns to the
normal operational mode automatically when the heater temperature is increased.
The antifreeze thermostat TPZ1W is used in the system with the room thermostat TP(TPP).

M Throttle servomotors
The servomotors whose task is to set the air throttle in the required position and to protect water
heaters against freezing are used to control external air throttles. Depending on a throttle control
method we use the servomotors of the following type:
»open/close “on-off”
»with continuous operation 0..10V. The setup of the throttle in the specied position is achieved
by applying the control voltage from the throttle ZW position controller of the value 0...10V.

Temperature Controller
The indoor Temperature Controller shown in is used to preset room temperature within range
from 8OC up to 30OC. The controller compares the indoor temperature (measured by an integrated
sensor) with the preset value. In case of irregularities, the Controller generates a controlling signal
(constant: 0...10V DC) sent to the actuator of the heating valve.

13. DEVICE STARTUP
Before start-up following should be done:
»check condition of the unit mounting,
»check water or steam connections tightness,
»check electrical power supply according to electrical board,
»check additional fan and unit casing protection,
»check correct connections to the motor,
»check fan direction of rotations.
To switch on the unit:
»open heat medium valves (steam supply valve should be opened gradually).
»switch on the power supply to the motor,
»adjust the direction and blown air range with use of the inlet grid blades,
To switch off the unit:
»restrict heat medium ow to the unit water heater (or cut off supply of the steam),
»switch off the power supply to the fan motor,
After a long period of standstill or in case of break in heat network operation the heaters
should be dewatered and the shut-off valves eventually closed.
14. REPAIR, MAINTENANCE AND WITHDRAWAL FROM SERVICE
The applied rolling bearings of the fan do not require a periodical lubrication. However, it is
recommended to check periodically a condition of the motor bearings (the rotor of the fan should
rotate freely without excessive backlashes and knocks).
When the noise level of the unit operation is increased it is necessary to check up the correctness of
fastenings of the fan and the whole unit (including the elements of additional equipment).
The rotor blades should be cleaned with a damp cloth after removing the protective net not to allow
unbalancing the rotor.
In case of any disturbances in the unit operation it is necessary to contact with the installer or the
service.
All maintenance and repair work should be done with disconnected power supply. The
unit should also be protected against accidental switching on by other persons.

17www.juwent.com.pl
The heater contamination state should be checked up periodically. The contaminated heater should
be blown through with compressed air.
The heater contamination reduces the air efciency and heating power of the unit.
Depending on the air pollution degree the lter contamination state in the intake box should be
checked up periodically. The contaminated lter should be cleaned (possible triple ltrating fabric
washing) or replaced with the G3 class fabric.
The contaminated lter reduces the air efciency and heating power of the unit.
After withdrawal from service the unit should be passed over to the specialized collection point of
recyclable materials.
