16. STANDING OFF
In the case compressor will be not to use for a prolonged time period, it is recommended to drain down the
condensate from pressure tank and the compressor put into operation for about 10 minutes with open valve
for condensate draining down (1) fig.8. Then switch off the compressor by switch (3) at pressure switch (2)
fig.7, close valve for condensate draining down and disconnect the appliance from mains.
17. LIQUIDATION OF THE APPLIANCE
• Disconnect the appliance from mains.
• Release air pressure in pressure tank by opening the valve for condensate drain down (1) fig.8
• Liquidate the appliance according to local valid regulations. Order the sorting and liquidation of waste in
specialized organization.
• Parts of the product after the end of its operating life do not have negative impact on environment.
