Condensate Drainage (Weekiy); Cleaning The Suction Filter (Monthiy); Further Servicing - Airpress dental star 36819 Gebrauchsanleitung

7.1 Condensate drainage (weekly) (Fig. 10)
For models without drier and automatic condensate drain.
Place a container under the drain valve and open the cock by turning it anti-clockwise.
As our "Oilless" series compressors do not require lubricant, the condensate
flowing out the tank is not polluted and can be eliminated through the sewer
system.
7.2 Cleaning the suction filter (monthly) (Fig. 11)
These models have one or two suction filters next to the compressor head. To open,
unscrew the middle screw.
Take out the filtering component and rinse with water and soap.
Dry completely and refit. Close the filter.
Do not operate the compressor without the suction filter fitted, as foreign bodies
or dust could seriously damage the inside components.

7.3 Further servicing

•
Every 6 months or 500 working hours
It is recommended to clean carefully all finned parts of the compressor. In this way
the cooling system is kept efficient and ensures a better performance of the
compressor (Fig. 9).
•
Every year or 1000 working hours
Change the filtering component (follow the instructions written in section § 7.2).
•
Every 2 years or 2000 working hours
1) Check and clean the suction and delivery valves
2) Check the non-return valve and replace the seal D, if necessary (Fig.12).
When you perform the above operations, we recommend to replace the
relevant seals.
•
At least every 3 years, replace the alumina contained in the drier. Such time span
has been determined by supposing an average use of the compressor (i.e. 2 hours
a day); in case of a more intense activity, have the air humidity rate checked by a
specialised technician and, if necessary, replace alumina in advance.
