5. DESCRIPTION OF COMPONENTS
Central VIP4Air Unit
The central unit of the lubrication system is composed of the three elements:
a Tank, made of transparent plastic material, compatible with lubricants on the market.
an air control system composed of a pressure regulator, applied laterally, and a solenoid valve, which can block the air flow.
the VIP4Air panel manages and controls the entire lubrication process: the time intervals, the lubrication flow rate, the air
pressure and the oil level. In addition it provides for priming cycles (air venting).
Pneumatic Mini-pump
The mini-pumps employed are particularly small and are installed on the mixer bases. They can be fitted with a range of spacers
which serve to vary the flow rate. The following table details how to recognize these and indicates the relative part numbers. To
change the spacers proceed as follows:
1. Unscrew and remove the brass cap (A).
2. Rotate shaft (B) until the hole (C) aligns with the relative slot.
3. Insert a Ø2 mm tommy bar in hole (C).
4. Unscrew hex. nut (D) using a 5,5 mm spanner.
5. Slide off the spacer (E) and replace it with the required one.
6. Replace and fully tighten nut (D), remove the tommy bar and replace cap (A).
