Personnel:

HVAC technician

Protective equipment:

Protective gloves

Safety shoes

Industrial safety helmet

Only specialist personnel are allowed to perform the

described work on the VAV terminal unit.

Only skilled qualified electricians are allowed to work on

the electrical system.

 CAUTION!

Danger of injury from sharp edges and sheet

metal parts.

Always wear protective gloves when handling the

unit.

The control component is delivered mounted on the VAV

terminal unit so that the work is limited to the electrical

wiring

and to the setting of

the control component 

Ä

  8.5   ‘Setting of the control

component’ on page  28 

.

When installing the VAV terminal unit, take particular

note of the following points:

Upstream section

A special upstream flow length is not required

for the TVE terminal unit.

Direction of airflow

For TVE terminal units with control component

XS0, the direction airflow is clearly specified (air-

flow direction arrow).

For TVE terminal units with control component

XM0, a preferred airflow direction is specified

(acoustic), alternative installation possible.

Fixing/suspension

Accessibility for service work

Information on this can be found in the VAV terminal unit

installation and commissioning instructions.

Installation orientation

Any installation orientation of the VAV terminal unit is

possible for both the XM0 (transducer with dynamic

measuring principle) and the XS0 (transducer with static

measuring principle). The terminal unit may be mounted

in such a way that the position of the control component

is above, below or to the side of the duct.
