Installation of Components and Accessories
Installation of Components and Accessories
In line with the connection of heat exchangers, humidifiers etc., the coil connection may only be
carried out by specialists with the necessary knowledge of relevant accident prevention regulations
and other standard regulations relevant to health and safety in the workplace, based on their training
and experience.
DAMAGE TO THE UNIT!
When mounting EVO-M units care must be taken to ensure that no loads are applied to the floor
panels. During installation work suitable measures should be taken to ensure that any loads are spread
across the bottom profiles (e.g. using grid walkways).
Prerequisites
• Check the unit for external damage and check whether it has been properly assembled and
anchored.
• Check whether anti-vibration and structure-borne sound attenuating mats have been provided.
This means that either:
– the foundation has been isolated from the unit using rubber plates (for example) where the unit
is installed on level ground and no special structure-borne sound isolation requirements exist;
– or, in the case of ceiling mounting, commercially available spring elements have been used;
– or, where very special acoustic requirements exist, an acoustics engineer has been consulted
when selecting the most suitable structure-borne sound attenuation method.
• Before you start with the coil connection, check the following:
– Drain valves must be installed at all low points in the water system to ensure that the water
circuit can be fully drained in order to carry out maintenance or repairs.
– A water drain with shut-off valve must be installed in order to drain the unit’s water system.
– Air vents must be installed at all the high points of the water system at easily accessible locations.
• Ensure that the piping system is flushed through until it is clean by others and a cleaning record
compiled.
Installation of air control and air conveying components
In order to prevent the transmission of structure-borne sound, a tension-free connection between air
ducts and the unit must be made using elastic connectors or structure-borne sound attenuators (also
compare „Structure-borne sound attenuation“ on page 26).
If you are connecting air ducts to the units via flexible connectors, the installation
length of the connectors must be less than their extended length.
Installation of air handling components with coil connection
Recommendations on water quality for heat exchangers that operate using low pressure hot water
(LPHW) and chilled water:
A good water quality – e.g. salt and lime-free drinking water – increases the lifetime and efficiency of
the heat exchanger.
• Check the limiting values shown in the table annually to prevent damage to the hydraulic system
and its components. If necessary inhibitors must be added.
