Heatsail DISC Betriebsanleitung Seite 35

3.2. Replacing the bulb
Your DISC is supplied with a R7S 230V/120 Watt (78mm) halogen bulb as
standard. The maximum permitted output power of the bulb is 120 Watt.
The electrical supply must be disconnected via the installation's breaker
switch before the bulb can be replaced.
You can replace the bulb by removing the 2 half rings and pull the glass
of the the DISC downwards. The bulb is held in place by a spring. Remove
the bulb by first pushing it to the left or right and thereby releasing it from
its socket. Then replace the bulb and reverse previous steps. Please be
careful never to touch the halogen bulb with bare fingers, as oils from skin
will significantly reduce bulb life.
3.3. Inspection
The DISC must be subjected to an annual inspection.
The user is not authorized to carry out his own inspections and repairs.
Inspection of the DISC must exclusively be carried out by qualified and
authorized technicians, in accordance with Heatsail's applicable standards
and regulations. "Qualified technicians" are understood to mean: people
who have completed a technical training course for the installation of
outdoor heating and who are familiar with the applicable electrical laws
and regulations.
The electrical supply must be disconnected via the installation's mains
breaker or by disconnecting the plug before any work can be carried out.
All repairs must be requested via an authorized distributor of Heatsail
products. A repair is only valid when original parts have been used.
Upon written approval by Heatsail, the entire control panel should be
returned in case of a defective cable.
Heatsail will not be held responsible for damage resulting from non-
compliance with the maintenance instructions.
