15. Ordinary maintenance periodical checks

The M versions are equipped with a membrane dryer consisting of a forced-ventilation cooling system,
a double filtration of 5 and 0.01 microns to ensure maximum air purity, and a fully automatic membrane
dryer. Correct operation of the compressor and periodic replacement of the filter cartridges allow the
membrane dryer to operate completely maintenance-free. More information can be found
at www.metasys.com

15.1 Condensate draining

Control condensate in the air tank (14). Release it at least once a
week, switching off the compressor and reducing line pressure till
1 bar. Place a container under the air receiver or close to the drain
system, open the drain valve (27) till the complete conden- sate
draining.

15.2 Cleaning/replacement suction filter

Cleaning the intake air filters (30) placed on the proper filter hol-
der on the top of cylinders, removing the holder cover with its
seals (unscrew the butterfly screw). Clean them every month with
compressed air or water, replace it if necessary.
In case of soundproofed versions it's important to grant a regular
compressor cleaning inside the cabinet.

15.3 Safety valve check

Check the proper safety valve (16) operating at the first compres-
sor running. Pull the ring placed at the top of the safety valve,
verifying the correct air exit
Warning! Safety valve must not be used to relief air from the air recei-
ver! Always protect eyes from compressed air using eye glasses

15.4 Air line and air dryer filter cartridge replacement.

Dryer pre-filtration and line filters cartridges (if present) must be replaced according to the maintenance
scheduling (Par. 14). Follow the present instructions:
Before performing any maintenance on the compressor make sure
that the power supply is switched off. disconnect the plug after
having turned in "0" position the switch of the pressure switch (pos.
18 in the exploded view). Make also sure that the air tank (14) is rele-
ased of any pressure check the pressure gauge (21).
