The inlet moulding has been designed to ensure full immersion of the elements, greatly reducing the risks of air locking. The heater is supported on two swivel feet; these can be rotated to permit either wall or floor mounting. The heater control components are positioned on the front face of the electrical enclosure. The desired water temperature can be easily selected on the EVO heater using the panel-mounted thermostat dial. The single or three-phase power is supplied through a top quality Schneider contactor. Safety and equipment protection is provided by the highly reliable flow switch. Over-temperature protection is provided by the thermal cut out (manual reset). The 6 kw and 8 kw heaters are made to order and can not be returned once ordered, unless faulty or needing a service.
