4. Dealers may login to the VMAC website to view the "VMAC Labour Time Guide"
(under “Agreements”) to see the allowable warranty labour times.
5. Warranty invoices must include the Service Ticket number, VMAC System ID#,
hours on the compressor, and a detailed description of the work performed.
6. VMAC Warranty does not cover consequential damages, overtime charges,

General Information
Optional Equipment Compatibility
While VMAC strives to design systems compatible with optional OEM equipment
(such as running boards), it is impractical to develop systems that accommodate
every OEM and aftermarket option or add-on. Whenever possible, VMAC
endeavors to advise of compatibility issues in the “Additional Application
Information” section of the manual. Even when specific optional equipment is
determined by VMAC to be incompatible, it does not preclude the vehicle upfitter
or end user from modifying the optional equipment to make it compatible with
the installed VMAC system. VMAC does not warranty or accept responsibility or
liability for the fitment, function or safety of any products modified in any way not
expressly outlined in the installation manual.
Before Starting
Note and label all parts that are removed from the vehicle as many
of the OEM parts will be reused during the installation of the VMAC
system.
Read this manual prior to beginning the installation to ensure familiarity with the
components and how they will fit on the vehicle. Identify any variations from the
application list such as vehicle model, engines, or optional equipment (e.g., dual
alternator, active steering assist, etc.).
Open the package, unpack the components and identify them using the Illustrated
Parts List (IPL) included in the Fastener Pack.
Hose Information
Depending on other installed equipment, it might be necessary to move the air/oil
separation tank from its intended location. The hoses used in VMAC compressor
systems have a specific inner liner that is compatible with VMAC compressor oil.
Use of hoses other than those supplied or recommended by VMAC may cause
compressor damage and may void your warranty. Please contact VMAC for
replacement hoses and further information.
Ordering Parts
To order parts, contact a VMAC dealer. The dealer will ask for the VMAC serial
number, part number, description and quantity. Locate the nearest dealer online at
www.vmacair.com/dealer-locator or call 1-877-912-6605.

Torque Specifications
All fasteners must be torqued to specifications. Use manufacturers’ torque values
for OEM fasteners.
The torque values supplied in Table 1 are intended for VMAC supplied components,
or for use as a guide in the absence of a torque value provided by an OEM.
Torque values are with Loctite applied unless otherwise specified.
Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts)
unless otherwise stated.
