Introduction
These operating instructions have been written for drivers, operators and the maintenance staff
of your air conditioning unit.
In this context, we refer implicitly to the compliance with our general installation guide-
lines. These can be obtained from the KONVEKTA technical after sales service:
[e-mail].
Please observe our valid safety instructions, available under www.konvekta.de/asv.html. In
case of order placement or any other conclusion of contract the safety instructions get inte-
gral part of the contract.
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
•Transport
This facilitates the handling and avoids trouble caused by improper operation. Working in com-
pliance with these operating instructions increases operation reliability and service life of the air
conditioning unit and reduces life cycle costs.
Please complete these instructions by adding the national provi-
sions for prevention of accidents and environmental protection.
These instructions are part of the air conditioning unit. Always
have a copy at hand in the driver’s cabin.
You will certainly understand that we will not recognize any warranty claims due to un-
proper handling, inadequate maintenance, applications that do not correspond with the
determined use, utilization of unadmitted fuels or the non-observance of safety provi-
sions.
KONVEKTA will annul without prenotice all obligations concerning guarantee, service
contracts etc. regardless if granted by KONVEKTA or its distributors in case other than
original KONVEKTA spare parts or parts bought from KONVEKTA AG have been used
for maintenance and repair.
These operating instructions contain all necessary information to operate your air condi-
tioning unit. In case you need more explanations please contact the next KONVEKTA

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)
