9. Cleaning, maintenance and
troubleshooting
■
Clean with a dry cloth. Never clean with water.
■
Keep the bare parts of the poles clean. Lubricate regularly
with acid-free lubricant for better contact with the ledges
and to prevent corrosion.
■
Also lubricate the pivots regularly.
If the heater produces a loud vibrating sound:
■
Stop the heating cycle
■
Are all contact surfaces clean and greased?
■
Is the ledge positioned level on the poles?
If this is not the case, follow the instructions below to
adjust the ledge.
1. Remove dirt, burrs, etc., from the ledge and poles and
lubricant lightly.
2. Place the ledge on the hinge point and rotate it above
the poles.
3. Loosen the socket screws and the bolts on the hinge
bushing by about half a turn.
4. Switch on the heater by pressing start. The ledge now
sets itself. If necessary, a dead blow (plastic) hammer
may be used.
