Amount of water of the registers:
The connection of the hydraulic connections can be done by sol-
dering, pressing (in connection with supporting sleeves) or by
means of flexible hoses resistant to oxygen diffusion and push-
fit systems. The use of flexible hoses is subject to the manufac-
turer's specification.
When making the hydraulic con-
nections, you have to use suitable
tools to avoid excessive tighten-
ing or twisting of the register
connections.
To ensure that no air remains in
the register and in the hydraulic circuit, the air is drained by
means of ventilation units present in the register.
If the unit is to be installed at a location having temperatures be-
low zero degrees, glycol must be admixed to the coolant in a
suitable ratio, to ensure that the freezing point of this liquid al-
ways stays below the minimum temperature of the operating
site. Please note that the use of an antifreeze necessarily results
in a loss in performance of the register.
Connecting the air ducts
The air ducts are attached by using pipe clamps, fixing lugs or
the like.
Optionally, a rubber lip seal can
be installed on the connection
pipe, to ensure tightness be-
tween the device and the pipes.
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.

In order to achieve a uniform cooling capacity, the
floor induction diffusers type Maintenance DISA-B
should be connected to the cold water distribution
system in parallel.
The floor induction diffusers type Maintenance DISA-
B are induction devices for "dry cooling". To avoid
condensation, the cold water supply temperature
must be selected such that it does not fall below the
dew point, which may make it necessary to install
protective devices (condensate monitors).
- 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.
