Note:-
In all cases the tank should be positioned so that it slopes
away
from the outlet
by
20mm
per
metre
of
length
of
tank
(1/4
inch
per
foot length). This is to
ensure
that
any
impurities
do
not
contaminate the oil
supply
feed. The customer should be
shown
how
to remove these impurities
from time to time,
or
this should
be
carried
out
at
its service
or
maintenance check.
Connections
on
the oil
supply
pipe
should
be
made
using compression fittings where possible.
Galvanised
pipe
or
fittings MUST
NOT
be
used.
Always
check
sealing
compounds
for
their
suitability for
use
in conjunction
with
oil.
