The use of the equipment referred to in this manual must be entrusted to qualified personnel with a basic knowledge of
mechanics, hydraulics and electrical systems.
It is the responsibility of the installer to use tubing suitable for the system; the use of inadequate tubing can cause problems
with the pump, injury to persons and create pollution.
Loosening of connections can cause serious safety problems; carry out a check before and after installation and, if necessary
retighten them.
Never exceed the maximum working pressure values permitted for the panel and the components connected to it.
Before any maintenance or cleaning operation disconnect the power supply, close off the air supply and discharge the pressure
from inside the equipment and the tubing connected to it.
Do not subject the panel, the connections, the tubing or parts under pressure to violent impacts; damaged tubing or
connections are dangerous and should be immediately replaced.
After long periods of inactivity check air tightness of all parts subjected to pressure.
Personnel must use personal protection equipment, clothing and tools adequate for the location and the use of the panel both
during its operation and during maintenance operations.
The panel, and any accessories mounted on it, should be carefully checked immediately on receipt and in the event of any
discrepancy or complaint the Dropsa SpA Sales department should be contacted without delay.

2. GENERAL DESCRIPTION
The
VIP
4
Air
panel is to be utilized for ‘on mandrel’ applications and machine tools.
Designed for high performance at a low cost, it is distinguished by its compactness.
The system is composed of a central unit which controls and manages the entire system.
The central unit regulates and controls the functioning of the modular doses and mixers, which are composed of pneumatically
controlled mini-pumps and the mixer bases. The mini-pumps can be fitted with a series of spacers in order to vary the flow rate
so as to cover a wide range of needs. Integrated inside the mixer base is a flow control, which is utilized by the central unit to
verify the correct functioning of the equipment.
The modular design of the system makes it extremely versatile; up to a maximum of
8
mixer bases can be installed.
The high technology utilized in this system permits a total control of the lubrication combined with a simplicity of installation
without resorting to superfluous connections.
3. IDENTIFICATION OF THE MACHINE
A yellow plate showing the product code, the supply voltage and the basic characteristics is mounted on the front of the oil tank.
