Installation, Mounting and Maintenance DISA-H
Construction subject to change.
No return possible!
Version:
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.
When charging the register, make sure by means of on-site ven-
tilation devices that no air remains in the hydraulic circuit.
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
induction diffusers type DISA-H should be con-
nected to the cold water distribution system in par-
allel.
The induction diffusers type DISA-H are induction
devices for "dry cooling". To avoid condensation,
the cold water supply temperature must be select-
ed 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 outlet 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 sections and of the acces-
sories of the unit can result in a substantial power
loss of the unit.
