up is found — replace the discharge line. Replace

 

 

as necessary.

 

 

Discharge Line Freeze-Up - The discharge line

 

 

must maintain a constant slope down from the

 

 

compressor to the air dryer inlet fi tting to avoid low

 

 

points where ice may form and block the fl ow. If,

 

 

instead, ice blockages occur at the air dryer inlet,

 

 

insulation may be added here. Or, if the inlet fi tting

 

 

is a typical 90° fi tting, the fi tting may be changed to

 

 

a straight or a 45° fi tting. For more information on

 

 

how to help prevent discharge line freeze-ups, see

 

 

Bendix Bulletins TCH-008-021 and TCH-008-022.

 

 

Shorter discharge line lengths or insulation may be

 

 

required in cold climates.

 

 

Insufficient coolant flow through compressor -

 

 

Inspect the Bendix AD-RP™air dryer was designed

 

 

primarily for use with compressors rated up to 30

 

 

CFM. Contact an authorized Bendix parts outlet or

 

 

a Bendix sales representative for assistance when

 

 

using the dryer with a compressor which has a rated

 

 

displacement exceeding 30 CFM.

 

 

Coolant line - Replace as necessary (I.D. is 1/2"

 

 

min.). Inspect the coolant lines for kinks and

 

 

restrictions, and the fi ttings for restrictions. Replace

 

 

as necessary. Verify coolant lines go from the engine

 

 

block to compressor and back to the water pump.

 

 

Repair as necessary.

 

 

Restricted air inlet (not enough air to compressor).

 

 

Check the compressor air inlet line for restrictions,

 

 

brittleness, soft or sagging hose conditions, etc.

 

 

Repair as necessary. Inlet line size is 3/4 I.D. the

 

 

maximum restriction requirement for compressors

 

 

is 25 inches of water. Check the engine air fi lter and

 

 

service if necessary (if possible, check the air fi lter

 

 

usage indicator).
