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.

Special Tools Required
None

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.

Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts) unless otherwise stated.

Torque values are with Loctite applied unless otherwise specified.

Illustrated Parts List

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.

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 1).

Place the aftercooler in position and drill the mounting holes (Figure 2).

• 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.
• Route the black nylon water drain tube to a suitable drain location.
• Connect the supply line from the air source to the “Air In” fitting (the recommended hose size is #12 hose). Support the fitting on the aftercooler with a wrench when tightening.
• Connect the tool delivery line to the “Air Out” fitting, (the recommended hose size is #12 hose). When tightening, support the fitting on the aftercooler with a wrench.
• Connect the red wire from the aftercooler through a 20 A fuse to a 12 V (constant) source using the recommended wire size (Table 2).

Table 2 — Recommended wire size

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 green wire to a good ground using the recommended wire size (Table 2).

System specific installation instructions continue on the next page.
