Installation should only be completed by a qualied electrician.
Electric Power
The electrical circuits within your house should be of the correct type and size for the appliance
wattage, consult your electrician for advice. It is recommended that the fused spur outlet is placed
10cm to the right of the appliance and 15cm from the oor.
The appliance is supplied with approximately 1.5m of power cable without a plug. The electrical
circuit should be isolated by means of a double pole switch or circuit breaker.
Main Components
The body of the Sun Ray Neptune consists of special cast aluminium ns, specically designed
to ensure a maximum rate of heat diffusion, the air circulation channels providing a very effective
convection effect.
The aluminium body contains a special heat conducting uid, lled inside the ns with a unique
procedure assuring a bubble-free content for a total uniform and silent delivery of heat. Do not try to
disassemble the body of the heater
Fitting the Appliance
The appliance should be hung as close as possible to the coolest wall in the room, however it is not
recommended to place it on a wall that is not properly insulated – if this is the case, the part of the
wall behind the unit should be insulated.
In a bathroom, the appliance must be placed within the protected zone and should not be reachable,
directly or indirectly by a person in the shower or bath. (Please see Important Safety Information)
The appliance should, never be mounted under a connecting plug, switch or Socket outlet.
To hang the radiator, place the radiator on the oor in the position it is to be installed. Locate the
bracket above the radiator with the point on the bracket in between the rst and second element
on both sides (gure 1.a). For radiators with more than 9 elements, the bracket should be placed
between the second and third element (gure 1.b).

Maintenance & Care
Sun Ray radiators require very little maintenance.
The surfaces of the radiator must not be cleaned with an abrasive product or those containing
granular substances.
We recommend regular cleaning with PH neutral products.
In order to clean the radiator, it is recommended that the electric power is switched off. Failure to
keep the SunRay Radiators clean may result in dust becoming burnt and depositing on the wall
above the heater in the form of dark streaks or patches. This type of marking is expressly due
to failure to keep the heater and surrounding area clean. ATC take no responsibility for any such
damage caused
