NOTE
This check con only be carried out after having
drained the circuit. If not, dangerous splashing of oil

a) Remove oil filler plug at (S a H and insert into orifice
gauge MR. 630-73/ 15 until it reaches the hottam
of the casing ( rotate crankshaft if necessary 1. The
oil level must be between the min. and max. marks on
the qauqe ( which correspond to a depth of oil of 21
to 29 mm ).
b I If necessary top up using TOTAL (< LUNARIA 25 ),
or SUNISO No.5 01 TEXACO CAPELLA << E )a
grade 500.
c) Remove gouge MR ‘630-73/ 15 and position the plug
with its seal.
3. Create a V(IEYU~ in the circuit :
NOTE This consists in creotinq a vacuum as complete
as possible in the circuit. to eliminate (by evaporation j
any trace of water which
would
hinder the operation of
the refrigerating system.
- In the case of replacing the compressor. fully unscrew
screws ( 2 1 and ( 3 1 then screw in screw ( 2 ) two
turns after having connected flexible pipe ( 4) to the
intake valve.
* In other cases see paras. 1 and 2
a) Connect flexible pipe ( 4 i to the intake valve and
flexible pipe ( 6 1 from the vacuum pump to top ( 5 1.
b) Fully unscrew screw ( 3 1.
c ) Open tap [ 5) and switch on vacuum pump. following
the instructions on the S.O.G.E.V.instruction sheet.
di Run pump for
a minimum
of 45 mins. Close tap ( 5)
and disconnect pipe ( 6 1 from it.
4. Refill the circuit :
a) Prepare the <( PRESTOGAZ n refill
Unscrew cf Presto-vanneu union ( 7 ) from tap ( 8 1
and connect it to the refill for this. make sure
I
forcing if
necessary ) that
clip on union ( 7) is
fully clipped onto ridge of refill The threaded hole
of the o Presto-vanne )a union must be in line with
the refill valve.
NOTE It is advisable to tighten the clip on the
o Presto-wane >) union. if the union has already
been used
for refilling.
