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 warrant 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.

Installation
Install the VMAC Air Aftercooler 70 CFM in a location that provides adequate air
flow and easy accessibility.
The unit should have a minimum of 8 in of clearance on all sides. Ensure there
is sufficient space to: remove the front panel, connect the air lines, connect the
wiring, and access to the manual drain.
The manual drain function can be placed in a remote location by removing the
drain valve and connecting a hose, rated for a minimum of 200 psi, between the
aftercooler and the relocated drain valve.
The aftercooler must be mounted upright to allow the automatic drain to function
as designed (Figure 2).

☐ Place the aftercooler in position and drill the mounting holes
(Figure 1 on page 11).
☐ Fasten the rubber mount feet securely. If using the optional VMAC mounting
brackets (P/N: A700143), install the aftercooler unit onto the brackets and
fasten securely.
☐ Connect the supply line from the air source to the “Air In” fitting (see Table 2 on
page 12 for recommended hose size). When tightening, support the fitting on
the aftercooler with a wrench when tightening.
☐ Connect the tool delivery line to the “Air Out” fitting, (see Table 2 on page
12 for recommended hose size). When tightening, support the fitting on the
aftercooler with a wrench.
☐ Install the water separator and Filter, Regulator, Lubricator (FRL) combination
unit in a position where the filters can be easily monitored and changed.
☐ Route the black nylon water drain tube from the air filter and water separator to
a suitable drain location.
☐ Connect the green wire to a good ground using the recommended wire size
(Table 3 on page 12).
To confirm a good ground, use an ohm meter to measure the
resistance between the ground point and the negative battery
terminal. Resistance should be less than 1 Ω.
☐ Connect the delivery line from the Eliminator to the water separator (it is best
practice to install the largest hose available to reduce pressure drops across the
system).
☐ Connect the red wire from the aftercooler through a 20 A fuse to a 12 V
(constant) source using the recommended wire size (Table 3 on page 12).
When installing the hose between the eliminator and the water
separator, ensure the hose is routed above the height of the water
separator to prevent water pooling in the hose.
Ensure the selected mounting location provides a minimum of 8 in of
clearance on all sides of the Eliminator.
Ensure the operator has easy access to the manual drain.

18 AWG wire.

Operation
In extreme cold temperatures, moisture in the drain lines can
freeze within minutes, to prevent a blockage, open the manual drain
immediately after use.
Daily Operation
At the end of each shift, shut the compressor system down and vent any stored air.
Open the manual drain valve, on the side of the cooler, to drain the air line; this will
prevent the water in the float bowl from freezing in cold temperatures which will
cause the automatic water drain to fail. Leave the valve open until the compressor
is started again.
Manual Drain
The VMAC air aftercooler has a manual drain valve to purge water from the ‘Air-In’
line entering the aftercooler.
