6. 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 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.
Only original spare parts should be used.
The operation of the unit with the fan without a protective net is forbidden.
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.
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.

7. MOUNTING
Suspension of the unit
The units can be hung on the wall or suspended to the ceiling.
A mounting console is used to install the unit on the wall.
The length of the bolts fastening the unit to the console – max. 20mm.
TROPIC-1

TROPIC-2
Side view Top view
The units can be suspended to the ceiling using 4 bars with M8 thread with spacing according to
the following picture.
TROPIC-1 TROPIC-2

9www.juwent.com.pl
A minimal distance of the unit to the wall or ceiling necessary to ensure a free air supply
to the fan is: 18cm for TROPIC-1 units, 25cm for TROPIC-2 units
When it is necessary to hang the unit on a partition, e.g. made of steel sheets, stiffening
proles should be used to avoid vibrations of the partition generated by the unit
operation and the noise level increase in the compartment.
A minimal distance of the heating unit to the construction partition from the unit sides
is about 20cm.
8. WATER INSTALLATION
It is recommended:
»- to connect the unit to the heating network by means of the lower spout of the heater and
the return of the heating medium by means of the top spout;
»- to use cut-off valves upstream and downstream the unit to enable its dismounting without
the necessity to drain the supply installation.
The solenoid valves should be connected in the heating medium supply line from the unit.
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 heaters of the units in the ceiling option mounting cannot be drained centrally.
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.
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.

9. 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 of the unit may be executed only by an authorized electrician
who 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) fans with internal thermal contacts TK (brought
to the terminal box or stuck in the motor circuit permanently). The electric connection of the fan
should be executed taking a service switch (WS) and overload and short-circuit protection devices in
the supply and control box into consideration.
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 fan should be inserted to the terminal box and fastened to the protective net
or fan supports by means of clamp bands. The thermal contact of the fan should be connected to
the circuit that controls the power supply of the fan.
The electric connection of the motor must be compliant with the electric diagrams located on the
terminal box. The exemplary connection and control diagram of the units are presented in the
picture 1.

10. AUTOMATICS
We can deliver the following items to the units:
- Supply and control box: Surface-mounted in the closed casing (equipped with a main switch,
overcurrent circuit breakers, short-circuit protection devices, signalling lamps), intended to
cooperate and control the elements of automatics.
One control box allows controlling a group of the units by means of single thermostat in the
AUTOMAT|MANUAL operation mode.
The supply and control box (1~230V/50Hz) 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.
The exemplary connection diagrams of the units with single-phase motors are presented in the
pictures 2, 3, 4 and 5.
- Rotational speed controllers of the fan: The transformer 5-step rotational speed controllers ARW
(1~230V/50Hz) allow controlling the air delivery and thermal power. The individual rotational speed
steps are selected manually.

12. 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.
The rotor blades should be cleaned with a damp cloth after removing the protective net not to allow
unbalancing the rotor.
Do not use high pressure washers to clean the fan.
In case of any disturbances in the unit operation it is necessary to contact with the installer or the
service.
All repair and maintenance works should be executed when voltage is off. The unit
should be protected against an accidental activation by other persons as well.
The heater dust contamination state should be checked up periodically. In case of excessive dust
accumulation the heater should be blown through with compressed air.
The excessive heater contamination reduces the heating power and air efciency of the
unit.
After withdrawal from service the unit should be passed over to the specialized collection point of
recyclable materials.
