Safety

1.1  Correct use

The electronic control component type Easy is used in

combination with a TROX volume flow controller for var-

iable volume flow rate control in ventilation and room air

conditioning systems (HVAC systems).

The control components Easy (controllerEasy for short)

is designed for use indoors to control clean room air.

Supply air area of application:

The usual conditioning in air conditioning sys-

tems allows the use of the Easy controller in the

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.

In kitchen air extract systems, a VAV terminal

unit may only be used if it has been ensured that

the extract air is cleaned as well as possible by

highly effective aerosol separators, observe

VDI 2052.

In unspecified applications, or when combined with pol-

luted air (e. g. dust) and moisture, a controller with static

differential pressure transmitter 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 aircraft

outdoors without sufficient protection against the

effects of weather

in humid air (even temporarily, i. e. in wet areas,

such as bathrooms with showers)

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 persons 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 state of the art, and designed in

accordance with current safety requirements. Residual

risks cannot be excluded, however, and you should pro-

ceed with caution. This section describes the residual

risks that have been identified in a risk assessment.

Always observe the safety notes in this manual to

reduce health hazards and prevent any hazardous sit-

uations.
