the warranty period. This period starts with the delivery of the product to the authorized
service. The repair period of the product is maximum 30 days.
The warranty does not apply in the following cases:
Defects arising from the use or assembly of the product contrary to the points in the user
manuals
Faulty electrical wiring
Damages and malfunctions caused by using a voltage different from the voltage written
on the label of the product
If the product maintenance and repairs are not carried out on time, regularly, by the

EN

Have repair and maintenance operations performed only by qualified
personnel who have received the necessary training and authorization. You
can find information about YILKAR authorized service centers on YILKAR's
official website, www.yilkarklima.com.
Do not reach into the unit and do not hold any foreign objects to the
condenser and evaporator fan when the device is in operation.
Please do not touch the condenser, evaporator or its connections with your
hands. The same is true for the resistor on the fan if it will run on the unit and
it has not cooled down completely.
Replace faulty parts immediately and have any detected faults corrected.
It is mandatory to use the necessary safety equipment in maintenance and
repair operations.
Carry out maintenance work only when the engines are turned off.
Before turning on the air conditioning unit, disconnect the battery.
Please pay attention to the following rules for your own safety:
1.2 Security and Legal Regulations
Read this service manual carefully before operating your YK 400 model roof type air
conditioner.
In case of problems that may occur as a result of improper use conditions, the warranty
is canceled and compensation claims are not taken into account.
ECE R10 – Electromagnetic compatibility regulation is the type approval test for
European automotive electronics. It has been successfully passed various tests including
RF immunity and emissions, transient immunity and emissions.
Electrically it has met the requirements for waste, explosion, fluctuating harmonics and
vibration.

2. Definition and Technical Information
YK 400 is an innovative designed roof top air conditioner developed for air conditioning
12 mt buses.
The unit, which is easy to install, includes a condenser and two evaporators, right and
left. These units need to be mounted on the roof of the vehicle and connected to the
compressor via hoses with R134a refrigerant circulation.
With its aerodynamic design, this unit only increases the height of the vehicle by 27 cm.
Thus, thanks to its design, resistance in air and fuel consumption is minimized.
It can operate in outdoor conditions at 45°. The air conditioner, which has a cooling
capacity of 35-40 kW, can have a heating function by joining the heat exchanger device.
Your air conditioner can use the waste heat generated in your vehicle's engine and can
provide heating power to your air conditioner with its current design. In this way, the
cooling of your engine is more effective, while your vehicle warms up.
YK 400 is universal, compact and economical with all its features.
2.1 What is YK 400 ?

2.2 How does it work?
Vehicle roof air conditioners are heat machines that provide passenger thermal comfort
by taking the heat inside the vehicle.
Vehicle roof air conditioners work with a vapor compression refrigeration cycle in
thermodynamics. There are 4 main parts in this cycle. These are the compressor,
condenser, evaporator and expander valve.
The refrigerant put into the heat machine is first pressurized in the compressor, and the
fluid pressure is increased from approximately 1 bar to 16 bar. Afterwards, the
temperature of the supercompressed and superheated gas in the condenser is taken and
the fluid is liquefied under extreme pressure. The high pressure liquefied fluid coming to
the expansion valve from here passes through the valve to the low pressure region and
evaporates. It needs heat during evaporation. While the ambient air passed over the
evaporator heats the fluid in the evaporator and causes it to evaporate, it cools the
environment and provides thermal comfort to the passenger cabin.
