Safety
1.1 Correct use
The electronic control component type Easy is used in
combination with a TROX air terminal unit for variable
volume flow rate control in ventilation and air condi-
tioning systems.
The Easy control component (controller Easy for short)
is designed for use indoors to control clean indoor air.
Supply air area of application:
–
The usual conditioning in ventilation and air con-
ditioning systems allows the use of the Easy
controller in supply air without additional dust
protection measures.
Extract air area of application:
–
Extract air with a low content of dust or lint (e.g.
office) allows the use of the Easy controller
without additional dust protection measures.
–
For dry extract air with a higher proportion of
dust or lint, a suitable filter must be used in front
of the VAV terminal unit.
–
For extract air with a high content of dust, lint or
sticky components, or extract air with aggressive
operating fluids, use a controller with a static dif-
ferential pressure transducer, e.g. TROX Com-
pact controller or universal controller.
–
Do not use VAV terminal units in extract air sys-
tems in kitchens unless the extract air has been
cleaned as much as possible with high-effi-
ciency aerosol separators; see VDI 2052.
In unspecified applications, or when combined with pol-
luted air (e.g. dust) and moisture, a controller with static
differential pressure transducer should be used, e.g.
TROX Compact controller or universal controller.
Incorrect use
WARNING!
Danger of injury or risk of damage to property
due to incorrect use!
Misuse of the control component can lead to dan-
gerous situations.
Never use the control component/device:
–
in explosion-proof areas
–
in aircrafts
–
outdoors without sufficient protection against the
effects of weather
–
in humid air (even temporarily, e. g. in wet areas,
such as bathrooms with a shower)
–
for areas of application that are not described in
this manual
Modifying the unit or using replacement parts that have
not been approved by TROX is not permitted.
1.2 Safety signs
The following symbols and signs are usually found in
the work area. They apply to the very location where
they are found.
WARNING!
Danger due to illegible signage!
Over time, stickers and signs may fade or become
otherwise illegible, meaning that hazards cannot be
identified and necessary operating instructions
cannot be followed. There is then a risk of injury.
–
Ensure that all of the safety, warning and oper-
ating information is clearly legible.
–
Replace illegible signs or stickers immediately.
Electrical voltage
Only skilled qualified electricians are allowed to work in
areas marked as having electrical voltage.
Unauthorised people must not enter areas, open cabi-
nets or work on components where an electrical voltage
is present and which are hence marked with this
symbol.
1.3 Residual risks
The VAV terminal unit is designed in accordance with
the state of the art and current safety requirements.
Residual risks cannot be excluded, however, and you
should proceed with caution. This section describes the
residual risks that have been identified in a risk assess-
ment.
Always read and comply with the safety notes provided
in the following chapters of this manual to reduce health
hazards and prevent any hazardous situations.
