Hydraulic chamber safety switch
Before starting any maintenance work in the hydraulic chamber of the sliding floor:
❒ Turn the safety switch to the "0" position
➥ The boiler follows the shutdown procedure and the discharge is deactivated
❒ Turning the selector switch past the "0" position engages the locking lever
➥ The switch can be locked with a padlock to prevent it from being switched on
again
On completion of the maintenance work:
❒ Remove the padlock
❒ Turn the selector switch past the "0" position to automatically release the locking
switch. The selector switch can now be turned back to the "1" position.
❒ Acknowledge the fault and press the Start button to activate the boiler
Guardrail
When working at a height, appropriate measures must be taken in accordance with
the applicable national industrial safety guidelines to protect against the risk of falling
(e.g. ladders, platforms, etc.). It is the responsibility of the operator to select and
provide these means.
Alternatively, a railing can be fitted to the top of the boiler as per EN ISO 14122.
