Air conditioning (A/C) odor treatment (liquid), P/N 116 1454 ODOR TREATMENT See: Tools and Equipment/116 1454 Odor Treatment.
Warning! Read warning text on pack before commencing work. Use protective goggles and gloves when spraying. Seal hole around the spray
nozzle with rags during spraying to avoid spray mist leaking out into the car interior. Ensure that ventilation is good.
Preparations for spraying
Opening the evaporator drainage
-
Check and correct if necessary that the drainage from the evaporator is not blocked.
-
Place a container below the evaporator drainage pipe in order to avoid spillage on the floor.
Warming up the evaporator
-
Select recirculation, set temperature control to max. heat and blower selector to max. speed. All vents should be fully open.
-
Shut off the air conditioning (A/C) compressor by disconnecting the cable terminals from the pressure switch (Pressostat) in the engine
compartment. (The compressor can be overridden if the air distribution selector is in the Defrost position and may therefore start up.)
