How do I disable school lock on my storage heater?

Modified on Mon, 2 Dec at 3:14 PM

If the jumper is on pins 2 & 3 or has accidentally been knocked off during transit/installation, this will activate the school lock.

To disengage school lock, put the jumper on pins 1 & 2. If the jumper is missing, and unable to be found, the boost lock jumper can be used temporarily so that the heater can be used. C click the help link below for further assistance.
