WHAT TO EXPECT FROM ENDO-CVT™
Congratulations
on purchasing the
highly innovative ENDO-CVT™ (Compressor Valve Tank)
.
Carefully follow these
instructions to ensure years of safe and reliable operation of your ENDO-CVT system. CVT is unique in multiple ways from
conventional air compressor systems and highlighted below are some of the distinctions to expect:
POWER WIRING
- The ENDO-CVT™ comes with 4 ft (1.2 m) long ground cable and 7.5 ft (2.3 m) long power cable adequate for
rear mounted battery scenarios. When extending the cable for front mounted batteries, AccuAir suggests using a 6 awg cable size
for running up to an additional 20 feet (6 m). AccuAir sells a power extension harness if desired.
LOW VOLTAGE SHUTOFF
- The ENDO-CVT™ automatically monitors the supplied battery voltage. If the battery voltage reaches
below 9.0 volts, the compressor will turn OFF until the battery voltage is increased to above 11.0 volts.The compressor pumps
fastest while the vehicle is running and charging (13.8 volts or higher).
PRESSURE RANGE
- The ENDO-CVT™ will begin pumping anytime the pressure is below 160 psi (11 BAR), the vehicle ignition
switch is turned ON, and the compressor head temperature is below the maximum limit. After starting, the compressor will
continue to pressurize the reservoir until 200 psi (13.6 BAR) (the status indicator will flash green more quickly as pressure builds)
and then purge off between 5 and 30 psi depending on the current climate and humidity level and the condition of the internal
desiccant air dryer.
HEAT
- It is normal for your entire ENDO-CVT™ to become warm or even hot to the touch as the reservoir acts as a massive heat
sink for the compressor. AccuAir has built-in a compressor head temperature sensor and an automatic shut-off when the
compressor head temp reaches 203F (95C) indicated by a slow red flash on the status indicator. If you reach the 95C shut-off while
you are in a precarious situation and require a little more air immediately, you can cycle your ignition OFF then ON within a 30
second time period to force the compressor to run until 221F (105C) if required, indicated by a fast red flash on the status indicator.
NOISE LEVEL
- AccuAir has gone to great extents to engineer the most quiet and vibration-free air compressor system on the
market. Don’t be surprised if your air compressor gets slightly more quiet after break-in and also be aware that it is common for
the compressor to have a slightly different tone while it traverses the pressure range.
INLET FILTER
- AccuAir suggests routing the supplied inlet air line and filter just outside the vehicle to reduce noise in the drivers
compartment. Keep in mind that the filter will often emit moisture during the purge cycle, so mounting it outside the vehicle and
pointed toward the ground is suggested.

WARNING:
Improper grounding of the ENDO-CVT™ ground cable can cause poor system
performance and even potential damage to your ENDO-CVT™. If you are unsure how to
achieve a proper ground, please contact AccuAir tech support at 877-247-3696.

WARNING:
Your ENDO-CVT™ may become HOT to the touch after repeated operations.
WARNING:
Operating your ENDO-CVT™ without the supplied air filter may damage your
compressor and void your warranty.
!
WARNING:
For proper noise and vibration isolation, the ENDO-CVT™ must be mounted as
shown on page 9 &10 only. Side mounting is not recommended and will generate more noise.
NOTE:
You may notice that the reservoir will drop pressure after it has gotten extremely hot
and then cooled. This IS NOT an air leak, instead this is due to the Joseph Gay-Lussac Gas
Law (P1/T1=P2/T2) ie compressed air loses pressure as it cools.
NOTE:
Extending the length of your inlet air line is not suggested as it can affect the efficiency
of the desiccant purge.
