Before connecting the unit, check the electrical system, especially the electrical
connections.
The unit may by operated only with proper connection with grounding wire.
Unit must be permanently connected to the electric installation equipped with protective
(earth) terminal, residual current device and service switch.
The thermostat protecting the heater from overheating must be included in the heater
control system.
It is forbidden to switch on the unit without working fan. Every stop of air flow have to
disconnect the heater.
Voltage-free status can only be obtained by turning off the service switch.
Service switch disconnecting all power lines should be located near the unit.
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 specified 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
The walls, ceilings or constructional elements of the object to which the unit supports or
suspensions are fixed should have proper strength.
It should be consulted with the designer of the object.
The bearing structures of the units or for the units with intake boxes can be freely
designed observing the strength requirements.
When it is necessary to locate the unit by a partition, e.g. made of steel sheets, stiffening
profiles should be used to avoid vibrations of the partition generated by the unit
operation and the noise level increase in the compartment.
