4.3 Completing and Testing the Installation   

□ 

Check all wiring to ensure that it will not contact any hot or 
moving components and will not interfere with the operation of 
the truck.  Secure all wiring with nylon ties and loom as required.   

□ 

Install the air box in its original mounting position. Secure the air 
box and connect the intake ducting.   

□ 

Connect the batteries.    

 

4.3.1 Safety Test   

□ 

Place the automatic transmission in Park or manual transmission 
in neutral and apply the park brake.  Turn the ignition key “ON” 
but do not start the engine. 

□ 

Check the control box to see if there is a number showing in the 
hour-meter. If there is no display, there is no power to the control 
box. 

□ 

Press the “ON” button.  The green light should come on and you 
should hear the compressor clutch engage. 

□ 

Release the park brake. The green light should flash and the 
compressor clutch should disengage and flash park brake.  
A

pply the park brake again and press the “ON” button. The light 

should come on and the clutch should engage. 

□ 

On automatic transmission trucks, the engine must be running to 
complete the final step in the safety test. This will be done after 
the pre-start checks have been completed. 

□ 

Turn the ignition key “OFF”. 
 

If the truck fails the test, check the wiring to make sure 
that all the connections are correct and secure.  If you 
require additional assistance, contact your local VMAC 
dealer. Call 1-888-241-2289 or 250-740-3200.
