sonal injury, including death and material damage.
Risk of damage to the unit!
This symbol indicates a hazardous location with a risk of material damage that can
also lead to personal injury.
Danger of electrical current!
Before carrying out any jobs on the unit, power the unit down to prevent injury from
electrical current. Ensure that the unit is secured against being switched on again at
an appropriate point of the on-site power supply.
Danger of scalding!
Before performing work on the valves or the inlet or outlet pipes, seal off the heating
or cooling medium inlet to prevent scalding. Commence work only after the heating
medium has cooled down.
Warning: risk of rotating components!
Rotating fan impeller wheel poses a risk of injury! Before performing any work on
the unit, ensure that the unit isdisconnected and not under voltage. Ensure that the
unit is properly secured against subsequentswitch-on at an appropriate point of the
on-site power supply.
Danger due to overhead loads!
Wear a helmet and safety boots to prevent injury from falling components, espe-
cially when fitting the unit to the ceiling. Ceiling installations should always be per-
formed by two persons.

The HyPower-Geko may only be operated indoors.
The HyPower-Geko is designed for wall and ceiling installation.
1.7 Improper use
The HyPower-Geko may not be operated:
– for handling outdoor air,
– in areas subject to explosion risk,
– in wet areas or
– in locations with high dust levels or aggressive air.
1.8 Safety regulations and codes
When carrying out installation, commissioning, maintenance and service of the Flex-
Geko units, all local safety regulations and codes as wellas generally established tech-
nical practices must be followed.
1.9 Modifications and changes
No changes, add-ons or modifications may be performed on the HyPower-Geko air
treatment unit or its components.
Changes or modifications of the Flex-Geko unit will invalidate the CE conformity and
render all warranty claims null and void.
1.10 Spare parts
Only original FläktGroup spare parts are allowed, since FläktGroup is not liable if third-
party spare parts are used.
Risk of damage to the unit!
In open systems (e.g. when using well water), used water should additionally be
cleansed of suspended matter using a filter to be installed at the inlet. Failure to do
so could result in a risk of erosion by suspended matter (consider the limit values
specified in Tab. 1-1).
Alsoensurethat the unitis protected fromdust andother substancesthatcan cause
acidic or alkaline reaction with water (aluminum corrosion).
Itis notallowedto useHyPower units,inparticular withacooling function,forsuction
of kitchen exhaust air containing organic acids, e.g. vinegar, formic acid or materials
containing aldehyde (e.g. cinnamic aldehyde). This can lead to corrosion of alumin-
ium fins. As a consequence unpleasant odours may occur.
User instructions!
The unit is considered to be used in an improper manner if it is applied for other pur-
poses or a purpose that is not covered by the scope of the given operation manual.
The manufacturer or supplier is not liable for any resulting damage; the user alone
bears the full risk.
The operator is responsible for proper use.
Proper use also stipulates the observance of the operation manual and the inspec-
tion and maintenance conditions defined by FläktGroup.
Risk of personal injury!
Improper use can cause personal injury and material damage.

2.3 Range of Application
2.3.1 Water inlet temperature
To prevent condensate from forming on non-insulated casing parts when the tempera-
ture falls below the dew point during cooling operation, certain minimum inlet tempera-
tures must be maintained. These temperatures depend on ambient temperature and
indoor relative humidity and are specified in the following diagram.
Example:
The room temperature is 28°C, the relative humidity is 60%. According to the diagram
(fig. 2-2), the minimum allowable water inlet temperature is 8°C.

2.6 Condensate pump
In cooling units, condensate may form and is collected in the coil drip tray. If a slope
for condensate drainageis not fitted, a condensate pump must be installed. This pump
drains condensate into drainage pipework located higher upstream.
2.6.1 Function of condensate drain
A separate level sensor is installed on the side of the unit at the condensate tray other than
the condensate pump, which performs the following functions:
– Start of the condensate pump when the condensate level exceeds 4 mm from the
bottom of the condensate tray.
– Switch-off of the condensate pump after the condensate is pumped out.
– Sends the signal ALARM if the maximum permitted height of the condensate level
of 12 mm from the bottom of the condensate tray is exceeded.
