2. Intended use
The KONVEKTA air conditioning unit is an air conditioning system that works with the ozone
friendly refrigerant R 134a and which creates a pleasant and individually adjustable room temperature by means of forced convection. The determined use includes also the observance of the operating instructions as well as the proof of regular inspections.
Attention for SD7H15:
Only clockwise rotation
Page 6
BAKL60T12AB Edition: 19.07.2017 Page: 6/10
3. General information 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 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 operation.
On our website www.konvekta.com in category >service< you will find a survey of contact details of all our
service partners close to your location
4. Operating elements
The air conditioning control KS60 is a control and regulation device for air conditioners in modern
buses. The bus driver is relieved from all questions of an optimum air conditioning in the passengers’ compartment by a simple and clear handling. All functions of the a/c unit are adjustable by
different key-buttons. Every button has an indicating lamp, called LED used as a control function of
the buttons or in case of operating. LED is shining red if button is pressed or if unit is in operation.
Control board KS60 is connected onto the original dash board lightning of the vehicle. This means
that in case of running vehicle lamp, night lightning of control board (LED green) is also activated.
☛ Note:
We recommend driving with automatic mechanism (Key S5, see 5.1). Additionally to the automatic
the following functions can be activated:
a) SMOG-flap manually, in order to prevent the entrance of exhaust fumes (in tunnels)
b) REHEAT-function to dehydrate the steamed up wind shield
4.1.1. Auto-test
If voltage supply to unit is interrupted, unit starts a self test immediately after reset. Here all entrances and exits are controlled:
Process of auto test will be show at the display:
1. Indication of all LED’s and display indication -88
2. Indication Software version: 03
3. Indication Configuration (DIP-Code, for example:) 08
4. Indication of auto-test code 01, 02... etc.
After self-test, the actual temperature can be read on display.

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 performance of the airconditioning unit

5.4. Recirc. Air operation => only in case of a/c units with Rec. air flaps option
In case of recirculated air operation (key S6 activated), the income of fresh air is interrupted and
the air inside the vehicle is going to be circulated which avoids that outside air, possibly dirty because of exhaust fumes (tunnel driving) has a chance to penetrate into interior room of the vehicle.
Start of the recirculated air operation: Press key S6, the LED-display will light up. This position
should not be adjusted very long. If windows are misting up, return air operation should be
switched off: If key S6 is pressed again the return air flap will be reactivated and fresh air operation restarted. The LED-display will go out.
Automatic: In case of a temperature difference of more than 5°C between the set temperature
(adjusted value) to the existing temperature the return air flaps switch to recirculated air operation.
Manual: If the button S6 is pressed, the recirculated air function of the return air flaps will be maintained independently from a temperature difference.
5.5. REHEAT activate / stop
=> Only for units with heating option.
Switching on of the air-conditioning system via button S5 afterwards the key S5 will be pressed
shortly twice (double click). REHEAT will be activated for a period of 20 minutes, the LED-display
will light up at the same time.
⇒ Operation of the blowers at the highest speed level by key S3 (increase of the air flow output)
⇒ Recirculated air operation must be switched off.
The premature termination of the REHEAT is possible by double-pressing the key S5.
5.6. Display of air duct temperature
=> Only for units with heating option.
While pressing buttons S1 and S6 actual air duct temperature is displayed for 2 seconds.
5.7. Indicate outside temperature => only in case of a/c units with heating option
=> Standard for units with heating, optional for units without heating starting software version 3.
While pressing buttons S1 and S4 actual outside temperature is displayed for 2 seconds.
6. Maintenance / Servicing
Please arrange regular dates for maintenance works and services with a KONVEKTA service station, as indicated in maintenance schedule bus no. WP07050618.
- Only qualified staff is allowed to carry out these works! -
For general instructions on repair – and maintenance works please contact via email:
TKD@konvekta.com
Danger of accidents!
Qualified staff in charge of installation and maintenance have to be trained in accordance with EN
378-Part 4 and (EG) 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 malfunction and so endanger operational reliability. We recommend having all works and modifications
carried out at an authorized KONVEKTA Service Station. The same applies to the regular
maintenance works as prescribed and specified in the maintenance certificate.
Before carrying out any maintenance works at your air conditioning unit, carefully read the
KONVEKTA safety provisions (TD00052A ) in order to avoid any dangers and accidents!

6.1. Oil change Compressor type KVX
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: “Technical data compressor”).
6.2. Return air grid
Clean the return air grid in the passenger area monthly, in case of enormous dirt weekly.
Important:
-
If the filter is soiled, the cooling performance of the air conditioner will decrease.
-
It is not allowed to operate the air conditioner without filter.
-
If filter is defective, filter must replace!
-
In case the a/c unit will be operated continuously with dirty filter, the evaporator blowers will be
damaged
-
Due to a reduction of the evaporator air flow, the a/c function „defrosting“ will be activated more
often resulting in a decrease of the cooling capacity and damage of the cooling compressor!
6.3. 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.
6.4. Troubleshooting
- Only qualified staff is allowed to carry out these works! -
