Mounting accessories
Valves and actuators
Valves and actuators shall not be installed ex works. During in-
stallation the manufacturer's specifications must be observed.
Temperature controls
The temperature controls are mounted in accordance with the
selected model. This is why the instructions enclosed with each
model must be followed. However, in order to achieve optimum
measurement by the sensors, the following basic information
should be observed:
Condensate monitor
The installation of a condensate monitor depends on the select-
ed model. Please follow the instructions enclosed with each
model.
Adjustment of the air deflection blades
To regulate the air flow, rotate the air deflection blades manual-
ly.
With blockwise adjustable blades, 5 blades can be adjusted si-
multaneously.
Checks
Prior to commissioning, the following items must be checked or
guaranteed:
During commissioning itself, the following items must be guar-
anteed:
- Do not mount the temperature control close to or above a
heat source (direct sunlight, lamps, television sets, radia-
tors, etc.), in places with draught air or directly opposite
to an air diffuser grille.
- Temperature controls must be mounted at least 1.5 me-
tres above the floor.
- Mounting temperature controls on walls toward the out-
doors should be avoided.
Prior to drilling, make sure that
at the location in the wall where the temperature
control
is attached no electric cables are present.
Faulty mounting of the sub-assemblies and of the
accessories of the unit can result in a substantial
power loss of the unit.
- Hydraulic connections were tightened properly and exhib-
it no leaks.
- Connecting and fastening elements have been sufficiently
tightened.
- Adequate access for carrying out the maintenance activi-
ties has been provided.
- Use the on-site ventilation devices to ensure that no air re-
mains in the register and the water circuit.
- The connecting and fastening elements have been suffi-
ciently tightened.
- In heating mode, the temperature of the discharged sup-
ply air is not above 40°C.
The adjusting angle of the air deflection blades
must not be more than ± 45°, in order to guarantee
its function.
At an adjusting angle of the air deflection blades
outside the straight air throw of up to 45°,
the cooling capacity of the heat exchanger
is reduced by up to 5%, and the horizontal throw is
reduced.
After these items have been taken care of, the cor-
rect fastening of the device must be checked.
