Installation
6.1
Requirements
•
Check the unit for external damage and ensure proper installation and anchoring.
•
Check if vibration and noise-dampening pads are provided. The following applies:
– either rubber pads are used for level installation to insulate the unit from the
foundation in a location where no special requirements for the neutralisation of
structure-borne noise apply;
– or very special acoustic requirements please consult an acoustic engineer to
select the most suitable method for neutralising structure-borne noise.
•
Check the following before performing coil connections of the unit:
– To allow maintenance and service, install drainage valves at all low points of the
water circuit to ensure that the water circuit can be fully drained.
– Provide drainage with a shut-off valve for emptying the unit’s water circuit.
– Air vents must be installed at all high points in the chilled water system at easily
accessible locations.
•
Clean the field-provided piping and create the relevant report.
6.2
Installing air-conveying components
In order to prevent transmission of structure-borne noise, enable a tension-free con-
nection between ductwork and unit by using elastic connectors or sound attenuators to
prevent structural noise transmission (also refer to "Neutralisation of structure-borne
noise" on page 19). If using flexible canvas connections between unit and ductwork,
installation length of the connectors must be smaller than their length in expanded con-
dition.
6.3
Installing air-handling components with coil connections
Recommendations on water quality for heat exchangers operating with pumped warm
water and pumped chilled water:
Water in proper quality, e.g. salt and lime-free drinking water, considerably increases
the service life and efficiency of the heat exchanger.
•
Check the limit values
in the table
once a year
to prevent damage to the hydraulic
system and installed components. If necessary, add inhibitors to water.
Unit connections at coils and humidifiers shall only be performed by qualified
licensed staff. Have qualified licensed staff or other individuals with proper profes-
sional training and experience in the relevant accident prevention regulations, as
well as other generally recognized safety and occupational health codes, perform
unit jobs.
EQUIPMENT DAMAGE!
When entering FläktGroup CAIR
fricostar
units ensure that no loads are applied on
the floor panels. For all installation and maintenance jobs take appropriate meas-
ures to ensure that all load is evenly distributed across the bottom profiles (e.g.
using grid walkways).
Ensure that unit surfaces are not damaged or
scratched!
