Master Lock WA 59 A - Manual (Page 5)

The heater requires very little maintenance and the
regularity of such maintenance will depend greatly on
the type(s) of waste oil being burnt. The cleaner the
fuel, the less maintenance is required.
In general:
*
clean combustion dish and overflow tube daily;
* clean burner pot, burner ring and combustion
chamber at least once a week. Ensure that the
air intake holes of combustion chamber and
lower side (3) at bottem connection are not
obstructed;
* clean heat exchanger, fuel supply pipe, tank
and filter once per heating season;
* combustion chamber bottom: as soon as the seal
around the bottom of the combustion chamber is
no longer visible, it is essential that it is
replaced, normally this is once per heating
season.
* Clean filling sieve, fuel tank and filter
regularly.
* The water in the tank can be drained by means
of a tap at the bottom of the tank.
TAKING OUT OF OPERATION
*
Switch to position "0". The fuel pump will
stop and the flame will be extinguished once
the oil in the combustion chamber is burnt.
* Remove the plug from the wall socket after the
air intake fan has cooled down.
* If the burner is not to be used for a long
period, combustion chamber, combustion dish,
heat exchanger and tank should be cleaned
carefully and protected against corrosion.
The heater is delivered with a spare seal. If this
seal is not replaced at the appropriate
time, leakages causing soot formation may occur. The
pedal assembly is equipped with an adjusting
screw (2).
If leakages occur or replacement of the seal is
necessary, adjust this screw so that the bottom of the
combustion chamber is set at more pres-sure against
the chamber.
