Structural/Accessory Maintenance

The evaporator drain hoses are routed to the water
tank to replenish the water level during unit
operation. However, water usage will vary
depending upon the load and ambient conditions.
An overflow hose on the water tank removes
excess water when particularly wet loads are
transported or when the humidify system is not
operating.
NOTE: Only demineralized or distilled water
should be used to prevent plugging of the
atomizing nozzle.
Pretrip Inspection
The following items should be inspected before
loading the container:
•
Check the water level in the water tank to
maintain an adequate water supply.
•
Check humidify system operation by
starting the unit, setting the Humidify
mode to ON and adjusting the humidify
setpoint (HUMSP) more than 2% above
the current humidity level in the container.
Verify that the air compressor operates and
that water is drawn into the atomizing
nozzle and injected into the return air
stream.
Inspection and Cleaning
The following items should be periodically
serviced:
•
Clean and inspect the filter in the water
supply hose on the water tank every 1,000
operating hours. Clean the filter screen
with fresh water and a soft brush.
•
Inspect the water tank, water supply line
and atomizing nozzle every 1,000 hours
and clean if necessary. Use fresh water, a
soft brush and compressed air to clean and
blow clear components.
•
Inspect the air compressor for signs of
overheating once a year.
