6 Maintenance
– Maintenance work on the electrical equipment may only be car-
ried out by a qualified electrician.
– The appliance must be disconnected from the power supply pri-
or to any maintenance work and in particular prior to repair work
(see 2 Safety regulations).
– The heating appliance, and in particular the electrical control
system, must be checked at least once a year according to DIN
VDE 0701/0702 (VDE 0701/0702) or according to comparable
test specifications. Independently of this the mandatory local
regulations must be observed.
ATTENTION:
– Under no circumstances may the heaters be operated 'dry' to
the air, since the internal construction will be damaged!
– Do not operate the cartridge heaters for a short period of time,
even for checking purposes, since they can be permanently
damaged or destroyed by this. Only carry out checks as
instructed.
NOTE:
The connecting screws on the heating appliance may only be replaced
with genuine original parts from Spheros.
A current measurement ensures that all cartridge heaters are functio-
ning. The current should be 28.5A ±3A.
High voltage! Danger to life!
