Danger of injury due to toxic substances!
Glycols and other antifreeze agents are harmful for humans and animals, if swal-
lowed.
•
Consult a doctor immediately if swallowed by mistake.
Notice!
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.
Risk of damage to the unit!
•
When entering CAIR units, ensure that no loads are applied on the floor panels.
•
For all installation work, take appropriate measures to ensure that the load is
evenly distributed across the bottom profiles.
•
Check the unit for external damage and ensure proper instalation and anchorage.
•
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 commercially available spring-based elements are used for ceiling installa-
tion;
– 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.
– Ensure that air vents at all high points in the chilled water circuit are installed and
can be easily accessed.
•
Clean the field-provided piping and create the relevant report.
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 "Structure-borne noise attenuation"
on page 27). If using flexible canvas connections between unit and ductwork, installa-
tion length of the connectors must be smaller than their length in expanded condition.
