These operating instructions have to be read carefully and made use of before the first start-up and after

that regularly by each person who is involved in handling the machine:

• Operation including troubleshooting and waste disposal of fuels and auxiliary agents.

• Servicing, inspection, repair

In vehicles that are equipped with an a/c unit with heating function the heating medium has to consist of

water/glycol – antifreeze protection (conform the mixing ratio to manufacturers` instructions). This is abso-

lutely necessary to prevent the heaters from frost damage!

(The prevalent antifreeze filling of the vehicle manufacturers goes down to -40°C)

The KONVEKTA

KONVEKTAKONVEKTA

KONVEKTA air conditioner represents 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 instruction and the

proof of regular inspections as well.

2.1. General information a/c unit

General information a/c unitGeneral information a/c unit

General information a/c unit

A/C unit is only operating with running engine. In case of cooling, humidity in the interior part of the vehi-

cle goes down which prevents misting up of windows.

The a/c units works most effectively if windows and doors are closed. If interior room of the vehicle is

enormously warmed up, a short time opening of windows/doors might help to accelerate cooling progress.

In case of hot outside temperatures and high humidity it might be the case that condense water drips off

condenser which causes a small water collection under the vehicle. This is quite normal and no signal for

leakage.

The filter in the return air grid (optional) retains dirt. Circulated air adjustment should be chosen in case of

dirty gaseous air from outside. Elements of the return air grid have to be exchanged according to the stipu-

lated times of service plan in order to possibly avoid performance reduction of the a/c system.

NOTE:

NOTE:NOTE:

NOTE:

KONVEKTA uses components made of copper and aluminium, which last a whole unit lifetime under nor-

mal environmental conditions. Should the units be operated under aggressive environmental conditions, i.e.

air containing salt-, phosphate- or ammoniac extremely, a corrosion of the cupper- and aluminium compo-

nents cannot 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.

Danger of accidents

Danger of accidents Danger of accidents

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 performance of the air-

conditioning unit
