WARRANTY

The warranty terms and conditions
issued by our responsible sales
company apply in every country.
Within the warranty period, any
faults in the unit will be rectified free
of charge provided that the problem
was caused by a material defect or
manufacturing error.
The warranty only applies if the
dealer fills in, stamps and signs the
enclosed reply card when the unit is
sold and the purchaser then returns
it to the appropriate local distributor.
In the event of a warranty claim,
please contact your dealer or the
nearest authorised After-Sales
Service office and produce both
accessories and proof of purchase.

GENERAL INSTRUCTIONS

Safety features
* Pressure switch
The pressure switch shuts off the
unit when the handgun is closed and
causes it to cut in again when the
handgun is opened.
* Safety valve
The safety valve opens quickly with
each closing of the handgun or
when the overflow valve or the
pressure switch is defective. Then
the out-flowing water escapes. The
safety valve is set at the factory and
sealed. Adjustment can only be
made by After-Sales Service.
* Low water protection
The low water protection stops the
burner being switched on in the
event of a lack of water. A strainer
stops the protection feature
becoming dirty and requires regular
cleaning.
* Motor thermal contact
The motor thermal contact interrupts
the electrical circuit when the motor
is overloaded.
