OPERATION OF EQUIPMENT
Drainage
Drainage of the air tank should be performed to eliminate the condensed water accumulation
inside the tank. The drainage frequency depends on environmental conditions and operating time,
on average the drainage is recommended to be done on a daily basis.
To perform the drainage, insert the hose which is connected to the register (13) located underneath
the tank inside a container for water disposal. Open the register slowly until all the accumulated
water is drained and air starts to ow again. Close the register rmly so that no leakage can occur.
Compressed air outlet
The air pressure on the outlet can be adjusted through the register
(09), check the setting on the pressure gauge (10).
The air outow rate can also be adjusted in the register (12).
In tandem with the pressure and ow rate registers, there is a lter
that removes moisture and impurities remaining in the air, the moisture
that is removed from the outlet will get stored in the reservoir (11),
to empty it press the pin underneath the reservoir.

CORRECTIVE AND PREVENTIVE MAINTENANCE AND PRESERVATION
Attention
Never wet the compressor or any of their parts. The cleaning of outside surfaces should
be performed weekly with a duster or soft cloth slightly moistened with water; the use of
other products may damage the compressor nish or plastic parts. Be sure to thoroughly
clean the head’s upper part, responsible for its cooling. The accumulated dust aects the
heat dissipation.
Cleaning
Important: In order to execute cleaning or any type of maintenance, ensure that the equipment is
disconnected from the electrical network.
Additional procedures for reuse
The equipment can be reused in undetermined, i.e. unlimited, quantities, only needing to be cleaned
and disinfected.
Preventive Maintenance
The equipment should be calibrated routinely, as per the legislation in force in the country.
But never with a period exceeding 3 years.
In order to protect your equipment, seek Gnatus technical assistance for periodic revisions of
preventive maintenance.
Filter Change:
Keep the air lter(s) (B) clean and in good condition
of usage. The air lter (B) prevents dust from entering
into the compressor and reduces the operating noise.
Over time, the lter will become dirty, reducing the
air inlet ow and causing the decrease of compressor
performance. The lter should be replaced every 3
months on average or before, depending on the air
quality. Additional lters are available for purchase
through the Gnatus Technical Assistance network.
To perform the change, open the lter enclosure by
turning the metal cover (A); remove the old lter and
insert the new one; put the cover (A) again by turning
it in the opposite direction.
