or isolate the equipment from mains. Wait
approx. five minutes before restarting the
device.
• Ensure pump fan is working and pump is
placed in an area with an ambient temp. of
less than or equal to 40°C
Ultimate vacuum cannot be
reached. Fittings or hose connection have leakage. • Ensure that fittings are tightened properly, use
