FUNCTION CHECK
Before use
• Check that the guidelines of the installation instructions about the
connection of supply media are followed: electric power, water,
compressed air, steam, etc.
• Check also that the guidelines for waste and ventilation have been
met.
• Check that the operating instructions are displayed at the unit.
• Carry out any customisations of the unit (where applicable). See the
section headed “Functions which can be programmed by the user” in
the chapter on ADVICE AND INSTRUCTIONS.
• Check that all the connecting screws belonging to electric cables are
sufficiently tightened. Pay particular attention to power wiring.
• Open the valves for all supply media.
• Check that the water tank level is about 13 mm (1/2”) below the spill
way. Adjust if necessary on the float valve.
• Check that the feed water enters at least 20 mm above the overflow
level.
• When the feedwater tank is full of water, check the direction of
rotation of the vacuum pump by briefly pressing the contactor. The
direction of rotation of the pump must agree with the arrow on the
pump housing. To reverse the direction of rotation, follow the
instructions under Electrical in the chapter INSTALLATION.
• If the vacuum pump does not draw sealing water immediately when
it starts, fill the feedwater tank to the brim by closing off the
overflow and holding down the float. It may also be necessary to
briefly open the pump throttle valve fully, to restore it to the correct
position when the pump gas started to draw water.
Read all the documentation and check that all supply
media are correctly connected to the connection points.
Do not let the pump run dry for more than a few seconds.
