7 Installation
7.1 Installation site
• The installation is installed in the technical control
room or in a separate, dry, well ventilated and
frost-proof room that can be locked (requirement
of DIN 1988 to be observed where applicable).
• Adequately dimensioned floor drainage (drain
connection or similar) must be provided in the
installation room.
• No harmful gases must penetrate the room or be
present there.
• Adequate space must be provided for mainte-
nance work. The main dimensions are given on the
attached installation plan. The system should be
freely accessible from at least two sides.
• The installation surface must be horizontal and
flat. The bearing surface must have adequate
load-bearing capacity.
• The system is designed for a maximum ambient
temperature of +0 °C to 40 °C with a relative
atmospheric humidity of 50%.
• Installation and operation in the vicinity of living
rooms and bedrooms is not recommended.
• To avoid the transmission of structure-borne
noise and to ensure a stress-free connection to
upstream and downstream pipes, expansion joints
with extension limiters or flexible connection lines
should be used.
7.2 Installation
7.2.1 Foundation/bearing surface
The system is constructed for installation on flat
concrete floors. The base frame is mounted on
height-adjustable vibration absorbers to prevent
structure-borne noise.
NOTE:
The vibration dampers may not be fitted when the
equipment is delivered for transport reasons.
Before installing the system, make sure that all the
vibration dampers are fitted and locked by the
threaded nuts (see also Fig. 8).
If the customer also wants to secure the installa-
tion to the floor, suitable measures must be taken
to avoid structure-borne noise.
