Do a test of the inlet pressures
1. With the gas flowing in test preflow mode, make sure that the pressure at the regulator is set to
7. 5 b a r ( 1 10 p si ) .
2. Repeat the test in cutflow mode, and make sure that the regulator is set to 7.5 bar (110 psi).
3. If you are using vented water injection processes, make sure that the inlet pressure for the water
is between 40 psi and 110 psi. (2.8 bar and 7.5 bar).
Examine all of the air filters
Examine all of the air filters for contamination.
If you find moisture or oil, replace the air filter.
If you find a moderate quantity of solid
contamination, such as dust, blow air through it
or use suction to clean the filter.
If you find a large quantity of solid
contamination, replace the air filter.
Do a check of the coolant level and condition
Make sure that the tank is full to the neck with coolant:
1. Open the cover of the coolant tank on the outside of the
enclosure.
2. If the level of the coolant is below the top of the tank, add coolant
(028872) to the neck of the tank.
3. Record the number of gallons your system requires in Coolant
requirements on page 39.
Examine the coolant tank for contamination. If you find any
contamination, then replace all of the coolant. See Replace the
coolant and coolant filter, and clean and examine the pump screen
on page 21.
