Special Installation Notes
If you intend to use an auxiliary air tank with this
system,
you must
observe the following installation procedure. Failure to observe this
procedure will result in damage to the system.
• The line from the VMAC tank to the auxiliary air tank must
have a check valve installed to prevent blow-back from the
auxiliary tank and to prevent moisture from entering the VMAC
tank, see Figure 3.
• The line to the auxiliary tank must not be installed in the
bottom of the tank. It must be installed as high as possible to
prevent sludge from the bottom of the tank from interfering
with proper check valve functio
ns.
Figure 3 - Auxiliary Tank Installation
Operational Limitations
The system must not be operated in excess of 15⁰ from horizontal, as this will affect
lubrication and air/oil separation.

Maintenance Schedule
During the warranty period, you must follow the maintenance schedule
and use only original genuine VMAC replacement parts to maintain your
system and your warranty.
The most critical aspect of maintenance is proper air filtration and clean
oil. If any particles enter the compressor through the air inlet, they can
contaminate roller bearings, gears, and the rotors in the compressor.
Contamination will cause severe, rapid damage to components.
Never run the compressor without the recommended air filter and filter
cover installed.
Y
ou must use VMAC certified and approved synthetic
compressor oil.
Failure to use this oil will result in damage to the compressor and will
void your warranty.
Maintenance Schedule
The following maintenance schedule listed in Table 2 should be observed to assure good
performance and long service life. The hours indicated are:
• engine hours where the compressor is directly mounted to the engine.
• actual compressor operating hours where the compressor is equipped with a
clutch to disengage operation from the engine.
Service should be performed at the lesser of the two intervals, hours, or calendar months,
whichever occurs first.
For replacement part numbers, check the appropriate Illustrated Parts List for your
application or call a local VMAC dealer.
