1. Technical data
Important!
In vehicles that are equipped with an a/c unit with heating function the heating medium has to con-
sist of water/glycol – antifreeze protection (conform the mixing ratio to manufacturers` instructions).
This is absolutely necessary to prevent the heaters from frost damage!
(The prevalent antifreeze filling of the vehicle manufacturers goes down to -40°C)

2. Intended use
The KONVEKTA air conditioner represents an air conditioning system that works with the ozone
friendly refrigerant R134a and which creates a pleasant and individually adjustable room tempera-
ture by means of forced convection. The determined use includes also the observance of the Oper-
ating instruction and the proof of regular inspections as well.

BAKL30T12AD Edition: 28.02.2017 Page: 6/14
3. Generally information for a/c unit
Attention in case of roof top a/c units: Never switch on the a/c unit during car-wash!
•The a/c unit is operational with running engine only.
•At cooling operation the humidity inside the vehicle is decreased, which avoids steamed up win-
dows. The a/c unit works most effectively with windows and doors shut. If, however, the interior
of the standing vehicle has been heated up severely by exposure to sunlight, short-time opening
of windows and doors may accelerate the cooling down process.
•At high outside temperature and humidity condensate might drip off the evaporator and make a
puddle under the vehicle. This is quite normal and no sign for a leakage.
•The filter in the return air grid (optional) retains pollution. If the external air is contaminated with
gas switch over to return air operation. The filter should be cleaned or replaced respectively on a
regular basis so that the capacity of the a/c unit is not affected.
•If you think that the a/c unit is damaged, switch it off immediately. To avoid further damage
have it check at a KONVEKTA Service Station. Only after that you can take unit into opera-
tion.

3.1. Operating Conditions
NOTE: KONVEKTA uses components made of copper and aluminium, which last a whole unit life-
time under normal environmental conditions. Should the units be operated under aggressive envi-
ronmental conditions, i.e. air containing salt-, phosphate- or ammoniac extremely, a corrosion of the
cupper- and aluminium components can not be ruled out. The cupper- and aluminium components
of the KONVEKTA systems are not suitable for such extreme application conditions. We indicate
emphatically, that corrosion is not subject to warranties for defects. KONVEKTA does not take over
any warranties for defect, neither for corrosion nor for consequential damage resulting there from,
nor for damages caused by cleaning the systems with highly compressed or corrosion advancing
substances.
4. Introduction control KS50
The KS50 is a climate controller for air conditioning
systems in modern vehicles. Due to its compact
design the controller can be mounted easily in the
dash board of the vehicle. The clear arrangement of
the symbols and the easy handling relieve the driver
and meet all demands of optimal air conditioning
control.
4.1. Installation
1. Choose suitable mounting place (the controller must not be exposed to direct solar radiation
through the windshield) and prepare a mounting cutout; width = 90,2 mm, height = 43,0 mm.
2. After the installation (wires laid out along the vehicle and 24-polar connecting plug positioned in
the dashboard control seat) plug the connection plug on the controller.
3. Insert the controller in the mounting cutout until the lateral mounting brackets lock.

BAKL30T12AD Edition: 28.02.2017 Page: 7/14

2. Press the mounting brackets together, either by hand or with a tool, and push the controller for-
ward.
3. Take off the plug and remove the controller.
5. Operation
Danger of accident!
– Focussing your attention on the road traffic is of top priority
– Only operate your air conditioning unit when the traffic situation allows it
– Make sure you can clearly recognize and read all operation- and display-elements at any time
– Protect all displays against irritating sunglare and any other optical disturbances
– Please note that the control panel keys have not been designed for heavy stressing
−Excessive or fast pressing of the keys for adjusting the set temperature does not accelerate the
cooling down process. It possibly damages the control panel and so affects the general perfor-
mance of the air conditioning unit.
