Safety Precautions

• Prior to installing the Boiler Switch, read through the wiring instructions
provided thoroughly. Make sure that you understand your heating setup as
specified on the following pages.
• Before proceeding with the installation, check and ensure that the boiler
is OFF and that no mains power is being received. Remember - the mains
terminals remain live even if the boiler's on/o controls are switched o . If
a separate wiring centre needs to be accessed, make sure that no power is
being received. If in doubt always consult a qualified electrician.
• Ensure that the Boiler is earthed.
• Never take unnecessary risks if unsure, as damage can be caused by an
incorrect installation.
• Do not strip the outer sheathing of flexible cables more than necessary to
prevent short circuits.
• Ensure that all cords pass through the cable clamps in the rear of the
control box and are securely fixed. Ensure that the power supply is
connected such that the current carrying conductors become taut before
the earth conductor should the supply cord slip from the cable clamp.
