OPTIONS Dual pressure
SAFETY
WARNING: Any pneumatic equipment that is, or may be
connected to the machine must be suitable for use with at
least the higher, rated pressure.
OPERATING INSTRUCTIONS
COMMISIONING
Check that switch and solenoid are functioning correctly.
Switch handle up: Lower pressure selected
Switch handle right: Higher pressure selected
STARTING AND USE
Select higher pressure setting with valve handle (handle to
right) and start machine normally.
If lower pressure is required then turn handle to up position.
Toggle between high and low pressure as required.
OPTIONS IQ SYSTEM
SAFETY
CAUTION: The compressor regulation system is adjusted to
maintain regulated pressure at the separator tank. DO NOT
adjust regulation to provide full regulation pressure at the
service valve when the IQ System is enabled. This will result
inC operation at excessive horsepower levels, causing
overheating, reduced engine life, and reduced airend life.
CAUTION: Excessively restricted filter elements may cause an
increase in the amount of aerosol water and oil carryover, which
could result in damage to downstream equipment. Normal
service intervals should not be exceeded.
CAUTION: Blockage of the condensate will result in flooding of
the vessels. If flooding occurs, excessive condensate may
enter the air stream and could result in damage to downstream
equipment.
CAUTION: Do not remove ubolts from both filters at the same
time. Removing both ubolts will place excessive stress on the
aftercooler.
NOTICE:
Do not operate at temperatures less that 2_C (35_F) unless
equipped with low ambient IQ option.
OPERATING INSTRUCTIONS
Starting and use:
Select desired air type using diverter valve and start machine
normally.
Using diverter valve, toggle between standard air and IQ air as
required.
