shall be switched off immediately. Remove fuse or disconnect battery power.
At least once a year the heater should be inspected and maintained as follows;
Remove the glow pin using the special socket tool. Inspect the glow pin for any damage to wires or
wire connections and scratches or buildup on the heating element. Wipe the glow pin clean with a
soft cloth only, do not use anything abrasive to clean the glow pin. If the glow pin shows any signs
of wear or damage it must be replaced.
Remove the atomizer screen with a hook-pick or pick and needle nose pliers. The atomizer screen
cannot be reused and must be replaced annually.
Inspect the atomizer screen chamber for buildup and clean with a small wire brush and vacuum out
debris if required. Confirm the small air inlet hole on the side of the atomizer screen chamber is not
obstructed with debris or buildup.
