Security devices
Attention
Guards (motor cover, coupling guard, housings, …)
are set up for safe use of the equipment.
The manufacturer cannot be held responsible for any
bodily injury as well as failures and / or damage to the
equipment resulting from the destruction, hiding or
total or partial removal of the guards.
Never exceed the maximum working pressures of the
equipment components.
Pressure hazards
Safety requires that a pressure relief air shut-off valve must be installed
in the pump motor supply system to allow trapped air to escape
when the supply is shut off.
Without this precaution, residual air from the motor may cause the
motor pump to operate and cause a serious accident.
Also, a fluid drain valve must be installed in the fluid system so that the
fluid can be drained (after shutting off motor air and decompressing
it) before any intervention on the equipment. These valves must
remain closed for air and open for the product during the
intervention.
