KONVEKTA

General information A/C unit

The A/C unit only operates with the engine running. In case of
cooling, humidity in the interior part of the vehicle goes down which
prevents misting up of w i ndows.

The a/c unit works most effectively if windows and doors are
closed. If interior temperature of the vehicle is high, opening of
windows/doors for a short period might help to accelerate cooling
process.

In case of high outside te mperat ures a nd hu midit y it is normal that
a higher condensation of water will occurs in the evaporator which will
result in greater amount of water dripping out of the evaporator drain
hoses.

The filter in the return air grid retains dirt. Circulated air
adjustment should be c ho sen in c ase of dirt y gas eo us a ir fro m out s ide.
Elements of the return air grid have to be maintained or replaced,
according to the stipulated service interval in order to possibly avoid
poor performance of the a/ c s ystem.

In case of an eventual damage of the A/C unit, operation should
immediately cease to avoid consequential damages. It’s
recommended to contact one of KONVEKTA’S Service Stations and
the unit should only be operated again after it has been checked
thoroughly by specialists.

Heating system

Heating system

1. Brief Introduction

The heating system is used to provide a warm comfortable
environment for passengers in the bus and provide a good view for
the driver in cold weat her. By the source of heat, the heating sy st em is
classified into two types: independent heating system and dependent
system.

The independent heating system refers to a heating mode that
the fuel burns in a special mecha nism to heat and circulate the wat er.

The dependent heating system refers to a heating mode that the
residual heat of engine is used t o heat and circulate the water.

By the installation mode of radiator, the heating system is
classified into wall-mounted type and box type. By the method of
radiation, the radiator is classified into natural radiation and forced
radiation.
