Removal
Note: Before removing the HVAC/Air Conditioning Unit,
the system must be discharged.
!MWARNING
The air conditioning system is a closed loop system
and contains pressurised refrigerant. No part of the
system should be disconnected until the system has
been discharged by a refrigeration engineer or a
suitably trained person. You can be severely
frostbitten or injured by escaping refrigerant.

!MCAUTION
Do not operate the air conditioning system when there
is no refrigerant in the system, otherwise the
compressor will be damaged.

!MWARNING
Do not carry out welding operations close to the air
conditioning refrigerant circuit. A poisonous gas is
produced when refrigerant comes into contact with
naked flames. Do not smoke or allow naked flames
close to the refrigerant circuit.
BF-1-9
The heater and air conditioning units are built into the
same module, enabling the units to be interchanged as
complete assemblies.
