STIEBEL ELTRON S-Power PERFORMANCE SERIES Heat Pipe Collectors - Manual (Page 6)

06
The Stiebel Eltron S-Power Performance Series HP evacuated-tube solar collector must be mounted and operated
according to theapproved safety rules and technical regulations, of each locale. During assembly, workers must
adhere to the respective national regulations for employee protection (e.g. OSHA) and accident prevention. This is
especially important when working on the roof.
Lightning Protection
N O T I C E
All electrical equipment with a metal housing must be grounded. This also applies to solar-thermal
systems. The pump set, pipes, reservoirs and collectors must be provided with a ground connec-
tion, i.e., be connected to earth just like any standard water pipe. Grounding requires a secure con-
ductive contact between the ground point and the collector. The grounding clips can be installed to
the collector frame. The solar circuit pipeline system has to be connected to the building’s ground
over short runs for both the feed and the return lines.
Handling Glass Tubes
WARNING !
The glass tubes have a vacuum. Damage due to external pressure, loading or twisting, application
of concentrated loads or force impact may cause implosion. Flying glass fragments may cause in-
juries. Only a certified heating contractor or North American Board of Certified Energy Practioners
(NABCEP) certified solar thermal installer should carry out dismantling and disposal. All materials
used are recyclable.
Maintenance
The maintenance of solar systems must be done by licensed heating contractors and relates mainly to the heat
transfer medium. The collectors undergo a visual inspection only. They have to be replaced if damaged or if the
tubes experience a loss of vacuum.
Single tubes may be replaced on-site.
Due to the nano coating on the vacuum tubes, the collector is self-cleaning. If, however, the tubes become dirty,
the collector may be cleaned with water.
DO NOT USE INDUSTRIAL CLEANERS OR ABRASIVE CLEANERS!
