Notes: The method of connection to the electrical supply must facilitate complete isolation and should
preferably be via a fused double pole isolator having a constant separation of at least 3mm in all poles and
supplying the appliance ONLY.
Alternatively, connection may be made via a fused 3 pin plug and un-switched, shuttered socket, both
complying with the requirements of National or Local Regulations. Neither thermostat nor switch are
supplied as standard equipment. NOTE: In the event of an electrical fault after installation of the appliance,
preliminary system checks are required to be carried out i.e. earth continuity, polarity and resistance to earth.
