Maintenance Tips
With proper maintenance, the Meritor WABCO air dryer will provide
years of reliable service, even under adverse operating conditions.
To provide additional protection against the harmful effects of
extreme heat or cold, here are a few helpful tips.
Dedicated Purge Tank
Optimum mounting location for the dedicated purge tank is above
the air dryer.
Extreme Heat
Make sure the compressor discharge line is long enough to keep
inlet air below 175°F (80°C). Figure 3.1. (Refer to Section 5.)
Figure 3.1
Extreme Cold
Make sure the air dryer heater is in good working order by running a
heater resistance test. Refer to the procedure in this section.
Check the line from the governor to port 4 of the dryer for oil and/or
water. Keep this line clean to help prevent freezing.
Meritor WABCO air dryer components are installed in the air dryer at
the factory and are designed to last for the life of the dryer. Under
some operating conditions, however, a replacement may be
required. Refer to Section 2 for replacement guide instructions.
