Before carrying out operations which could cause the escape of refrigerant fluid, the air condi­
tioning system must be drained. Protective gloves and goggles should be worn during this op­
eration.
In order to facilitate the draining operation, the engine and the system should be left to run for at
least 10-15 minutes.
N O T E If the O-ring seals are being replaced, use green or black coloured seals, making sure that they
are current production ones which are resistant to R134A fluid. Do not, under any circum­
stances, use old production black seals because they are permeable.
N O T E If the system pipes are dismantled, it is advisable to seal the disconnected ends of the pipes
with suitable plugs if they are not going to be refited immeidately to prevent dampness or for­
eign bodies from entering.
