5.15 Air Compressor: PN 47600EC100, 47600SC100
Two machine models in the EZ 1000 Series II line of melters include an air compressor unit which is
designed to assist in the cleaning of debris from cracks and joints.
•
Always use approved high pressure air hoses with properly installed fittings which are not
frayed or worn.
•
A cold air lance is supplied.
•
Consult Crafco, or your hot air lance manufacturer for the appropriately sized hot air lance to
use on the following machine models:
o
For PN47600EC100 100 CFM (2,831.7 l/m) @ 125 PSI (8.61 bar)
o
For PN47600SC100 100 CFM (2,831.7 l/m) @ 125 PSI (8.61 bar)
•
The engine RPM is set by the factory for maximum engine and air compressor performance.
•
The engine RPM will increase to full RPM once the material temperature reaches 275°F
(135°C) or if the compressor is switched to the “ON” position.
•
If the compressor is switched on before the engine is at full RPM, there will be a short delay
as the engine speeds up, then the compressor will engage once the engine is at the correct
RPM.
•
If the compressor is not needed, turn “OFF” the toggle switch in the control box (labeled
compressor)
•
The compressor is operated hydraulically and runs continuously. When air is not being
discharged, the compressor automatically closes the intake valve and goes into an idle state
which takes less energy to operate but still maintains the RPM.
•
There is an internal air leak at the air muffler that provides lubrication of the compressor.
•
Do not replace the air muffler with aftermarket parts as damage will occur to the compressor.
•
Air compressor use in high elevations.
o
The Tier 4 Final engine de-rates itself to produce cleaner emissions when the
machine is above 8200ft (2500meters) elevation. Since the engine loses some of its
power, you may not be able to run the compressor while the machine is heating,
agitating and pumping sealant. If the compressor is used above that elevation, the
engine will most likely stall. If the engine stalls, turn off the compressor, turn off the
burner power switch, re-start the engine, turn on the burner power switch and
continue use without the air compressor.
•
PN 47600EC100 or 47600SC100 equipped with the 100 CFM air compressor comes
equipped with an air safety shut off valve. In the event of a hose rupture, this valve will
significantly reduce the air flow to prevent injuries from a failing hose. This valve will also
trigger if the compressor is started without the hose and wand connected. To reset valve,
shut off compressor toggle switch for 30 seconds, then turn on the compressor.
