INTRODUCTION
The underwing air conditioning system fitted to Standard Steel
Saloon Rolls-Royce Silver Cloud II
and
Bentley S.2 motor cars
provides de-misting, de-frosting,
car
heating
and
ventilation.
Alternatively, a comprehensive underwing refrigeration system,
providing a wide range
of
heating
and
cooling conditions, can
be installed at the customer's request.
Whilst servicing
of
the
standard
heating
and
de-misting
system may be undertaken with confidence by
the
normal
service engineer,
it
must be appreciated that correct main-
tenance
of
the refrigeration system will be better effected by a
specialised refrigeration engineer.
Special equipment
and
precautions are necessary when
un<lenaking
scrvidng
and
overhaul
operations
and
it
should
be
always
remembered that
the
refrigerant
circulation system is
sealed
and
pressurised.
Thus
join
ls
should not
bl!
disturbed
unnecessarily as
the
system must be discharged prior to
breaking any joint, unless this
is
protected by service valves.
The Refrigeration System, although
an
optional extra, is in
fact not an isolated unit, but a large system carefully integrated
into the design
of
the motor car. The electrical wiring, in most
cases, is combined in
th~ main wiring looms
and
the individual
mechanical
and
electro•mechanical control units have been
installed in positions promoting simplicity
of
operation
and
the
facilitation
of
servicing.
