1. Technical data air conditioning unit
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)

1.1. Compressor
Important: To avoid leakages at the shaft seal of the compressor:
The compressor should be started every 4 weeks for approx. 15 minutes! This also applies when
the vehicle is not into operation for a longer period or when the air conditioning unit is not used!

2. 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
windows. The a/c unit works most effectively with windows and doors shut. If, however, the in-
terior 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 dam-
age have it check at a KONVEKTA Service Station. Only after that you can take unit into
operation.

BAKL481602A Edition: 01.03.2017 Page: 6/11
1.2. 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 Op-
erating instruction and the proof of regular inspections as well.
1.3. 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 cannot be ruled out. The cupper- and aluminium compo-
nents 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.
3. Operation
Danger of accidents!
−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 sun glare 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.

Danger of accidents!
Qualified staff in charge of installation and maintenance have to be trained in accordance with EN
378-Part 4 and (EC) No.307/2008 and must strictly follow the legal provisions.
Any works or modifications at the air conditioner which are carried out improperly can lead to mal-
function and so endanger operational reliability. We recommend having all works and modifications
carried out at an authorized KONVEKTA Service Station.
Before carrying out any maintenance works at your air conditioning unit, carefully read the
KONVKETA safety provisions (TD00052A) in order to avoid any dangers and accidents!

BAKL481602A Edition: 01.03.2017 Page: 10/11
1.6. Compressor type KVX
Make the first oil change at the first maintenance of the vehicle. Then approx. every 3 years. At
every oil change the oil suction strainer has to be cleaned. Observe the oil quantity according to
the compressor type (see chapter: 1.1).
1.7. Return air grid
Clean the return air grid in the passenger area monthly, in case of enormous dirt weekly.
1.8. Condenser coil
Always keep condenser coil fins clean. Severe soiling cause’s excess pressure within the a/c-unit
system and it automatically stops working.
Attention: The condenser coil fins have to be cleaned with compressed air at least once a
year, in case of severe soiling more often.
1.9. Troubleshooting
Only qualified staff is allowed to carry out these works!
