WHAT IS THE “TEST PROGRAM”?
The TEST PROGRAM can be activated by a qualified service man to test a new
installation. This feature allows the serviceman to proceed through a series of tests where
individual components of the Humidaire Unit can be calibrated and adjusted. It may also
be used in the future by the operator or service man to troubleshoot a problem.
The test program is also performed on each new Humidaire Unit before it leaves the
factory. See the
TEST PROGRAM section of manual for more information.
WHAT NEEDS TO BE DONE AT THE END OF THE SEASON?
During the last days of the ginning season we recommend using our Powdered Acid
Descaler (part number 14000) to assist in removing scale from the piping and spray
chamber of the Humidaire Unit. We also recommend using the descaler periodically
during the ginning season if excessive scale buildup is noticed. See
POWDERED ACID
DESCALER section for instructions on its use.
When the unit is finished for the season, wash any sludge from the tank and use the drain
outlet to empty the tank. Also wash and scrub the strainer screen on the tank inlet to the
water pump as well as the mist eliminator. Use the plug in the bottom of the water pump
to drain it.
Use an air hose to blow dust buildup off burner duct, water pump, and gas valve
assemblies. Cut off the gas supply at the ball valve. Disconnect electrical power.
IS THERE ANYTHING I CAN DO TO ENHANCE PERFORMANCE?
See the section SUGGESTED ROUTINE MAINTENANCE for tips on maintaining the
unit in top form for maximum performance during the season.
INSULATION: In areas where the weather is sometimes cold during ginning season,
insulating (lagging) the humid air pipes and the lint slide is a good idea. This will
usually allow the air and water temperatures to be set closer together, enhancing
operation.
For Conditioning Hopper Systems operating in cold climates, insulating the manifold
pipes connecting the air to the Hoppers is a necessity. Keeping the moist air temperature
uniform throughout the manifold piping ensures the moisture application is uniform at
each gin stand.
A cost effective method of insulation is to wrap the moist air pipes with 4 inch thick
fiberglass batt insulation. Cover the insulation with Cotton Koozie Shrink Wrap Film
(part number 20750) and shrink in place with a propane powered heat gun. Heat guns are
available from the factory for rental or purchase.
