to the fully closed position.
It
will
then
be
necessary
to
adjust
the
two
actuators
separately as follows: -
Evaporator
flap
actuator
I.
Rotate
the extension spindle anti-clockwise
(when viewed over the left-hand wing) until
resistance is encountered.
2.
Slightly slacken
the
crank
lever
clamping

and
rotate
the
crank
lever until
it
slopes forward
and
upward
at
45 °.
3. Place
the
gear
shaft
crank
lever loosely
in
position
on
the
gear shaft.
4.
Adjust
the
position
of
the extension crank
so
that
when the gear shafi crank is rotated
clockwise
on
the
shaft,
resistance
is en-
countered
for a few degrees
to
each
side
of
the
fully
rearward
position. (This indi-
cates
that
the flap is being pressed tightly
into
its fully closed position).
Tighten
the
clamping bolt to lock
the
extension spindle
crank.
5.
Rotate
the
gear
shaft
crank
to
the
fully
rearward
end
of
its
stroke
(i.e.
when
the
gear
shaft
crank
and
the
connecting
link
are parallel) then tighten the clamping bolt.

2. Slightly slacken
the

and
rotate
the

lever until
it
slopes 60°
forward
of
the

3. Place
the

in
position
on

4. Adjust
the
position
of
the

so
that
when
the

is rotated clockwise
on
the shaft, resistance
is
encountered
for a few degrees
to
each
side
of
the
fully

SOLENOID VALVES
Model . . Danfoss EVJD-6 (Stamped '
F'
on the
valve body).
The
solenoid valves
control
the
flow
of
refrigerant
to
the expansion valves which serve the
two evaporator matrices.
The
lower end
of
the
movi,ng core has a rubber
insert which seats against a nozzle protruding
upwards
from
the
body
of
the
valve.
When
the
circuit
is
open,
the
core
seat
is held
against
the
nozzle
by
a
spring-loaded
plunger
which is
situated in the core so as to extend from the upper
face
and
contact
the
blind
end
of
the
so
len
oid
bore (see Fig. 8).
