DIAGNOSTIC PROCEDURE FOR DEFECTIVE COMPRESSOR HEAD(S)
1. Put power switches in the OFF position.
2. Reset the circuit breaker if it was previously tripped.
3. Test heads by turning ONE on at a time. If the motor fails to start, or the circuit breaker trips, the problem may be in that compressor
head. Leave the power switch for the defective head in the OFF position. Call your Authorized Air Techniques dealer for service.
NOTE: One head may be run TEMPORARILY while waiting for service.
4. If all heads run independently, but will not run together, check the line voltage. If the voltage is within the min./max. voltage required
in PRODUCT SPECIFICATIONS, call your Authorized Air Techniques dealer for service.
