1.1 Warranty and Liability Warranty conditions YILKAR assures its customers that the products they buy are manufactured in accordance with today's technology and without any errors. All YILKAR Authorized Dealers are obliged to carry out warranty transactions regardless of which authorized dealer the vehicle is sold by.
1.2 Security and Legal Regulations Read this service manual carefully before operating your YK 135 MB 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.
2. Definition and Technical Information 2.1 What is YK 135 MB? YK 135 MB is an innovative designed air conditioning device developed for air conditioning minibuses up to 17 seats. The easy-to-install unit includes a condenser and an evaporator. These units must be mounted on the roof of the vehicle and connected to the compressor via hoses circulating R134a refrigerant.
3.2 General Description Fiber Cover The cover made of fiber material is mounted on the condenser unit on the vehicle roof and acts as a condenser protection. Condenser It is the air conditioning system element in which the high pressure R134a refrigerant gas taken from the compressor in the condenser air conditioning system becomes liquid by giving heat to the environment.
Page 12
Compressor It is the pump of the system that compresses the R134a air conditioner gas in the compressor air conditioning system and increases its pressure. Relay Board The relay switches on and off the current path with the help of current and voltage values in the air conditioning system.

Assemble 13/32 , 5/8 and 5/16 hoses to protect them from internal and external factors. Keep away from the moving elements and hot parts of the vehicle, make the assembly by isolating it from all sharp edges and corners where the line will pass.
4.5 Electrical Connections 4.5.1 Control Un t Mount ng Surface to be mounted YLK 12/24 Control unit The unit location should be ergonomically chosen as a flat surface in an area accessible to the driver. Mounting surface dimensions should be 90x45 mm. Assemble the control panel sockets to the unit as shown in the figure.
