IMPORTANT
Consult the safety and cleanliness advice and oper-
ation recommendations before carrying out any
repair (see 62A, Air conditioning, Air condition-
ing: Precautions for the repair, page 62A-1) .
Note:
Use blanking plugs for the fuel circuits with part
numbers 77 01 208 229 or 77 01 476 857 to plug
any openings exposed to the open air. They must
be clean. Do not use plugs which have already
been used to plug a fuel circuit.
Note:
The « expansion valve - intermediate pipe » and
« expansion valve - dehydrator reservoir » connect-
ing pipes cannot be separated.
WARNING
Consult the device's operating manual to avoid
incorrect use.
