SYMPTOM

POSSIBLE

CAUSE

REMEDY

Compressor starts too
slowly

Wye Delta switch time set
too long.

1. Contact

your

Champion

distributor.

Minimum Pressure/Check
Valve is faulty.

Repair or replace.

Supply voltage is too low.

Check the supply voltage.

Compressor is low on
delivery and pressure

Restricted air filter.

Clean or replace filter.

Sticking inlet valve.

Inspect and clean inlet
valve.

Minimum pressure valve
stuck closed.

3. Replace

valve.

Leaks in the compressed
air system.

Check for leaks, fix any
leaks found.

Aftercooler is frozen

Thaw out. This machine
cannot operate in
temperatures below 32

C).

Unload pressure adjusted
too low.

Adjust the unload
pressure. See Manual
13-9-653.

Excessive oil
consumption

1. Oil

carryover

through

lines.

See “Oil Carryover”, in this
section.

Oil leaks at all fittings and
gaskets.

Tighten or replace fittings
or gaskets.

Shaft seal leaking.

Replace shaft seal.

High discharge air
temperature

1. Thermostatic

mixing

valve

stuck open.

Repair or replace valve.

Dirty or clogged cooler
face.

2. Clean

cooler.

Insufficient cooling air flow

Provide unrestricted
