• ‒ → Remove heater .
• ‒ Press back catches -B- and remove the heat exchanger -A- from the heater.

Notes:

• ◆ Secure the installed heat exchanger in the heater flap unit using 2 suitable screws -C- (e.g. 3.2 x 20 mm self-tapping screws).
• ◆ The heat exchanger is installed in the heater flap unit without an all-round seal (vehicles without map-controlled cooling).
• ◆ The refrigerant hoses are to be connected on the correct side. Different connection and flow direction of the refrigerant dependent on the type of heat exchanger => Page 80-41.

• ◆ The heat exchanger has been installed in vehicles with map-controlled cooling (to be introduced gradually as of model year 1999 vehicles with 1.6 l engine) which has been adapted to the different usage conditions. The following must be noted for this heat exchanger:

• ‒ → The flow direction of the refrigerant in the heat exchanger is not marked at the refrigerant connections (observe feed and return flow).
• ‒ The heat exchanger components carrying refrigerant are produced entirely from metal due to the higher feed refrigerant temperature.
