7. Periodic
maintenance
and
trouble-shooting
To
maintainyourRefrigeratorsafeandefficient we
recommendyouto carryout a simpleprogram of
preventivemaintenance.Thisroutineshouldbe
applied at leasttwice a year,preferablybefore a
seasonof
continued
use and'speciallyif the
Refrigeratorhasbeen closeddown forsome time.
Dudng andafter the
maintenance

from
combustible
materials,

other
flammable
vapors and
liquids,Also keepthe flow of combustionand
ventilationair unobstructed.
Donot use thin objects

6.7 The igniter
The
igniter
(05)
is
Ihe
piezoelectric
type,
which
causesa
high-voltage
spark Io jump betweenthe electrode(H3)
and the burner(H2). If
it
fails to operate,the taull may
lay

problems,[.o.
from
too
great
a
distancebetween
electrode
and
burner,
to creepage
or
poor

contact.
If suchp_oblems
can
be ruled
out,the igniter
shouldbe exchanged.
Do notput the igniter
