Page 56: 14900A Lint Flue Scanner Installation, Settings And Use
The 14900A control is used to determine when cotton is passing through a lint flue. It is used with the Samuel Jackson Humidaire Unit to operate its water pump only when cotton is being ginned. The 14900A control has a special mount which allows the 14953 photoelectric infrared scanner to look through a tiny window at the oncoming flow of air and lint.

Page 80: Supplemental Section
SUPPLEMENTAL SECTION Following is information on Samuel Jackson moist air applicators for seed cotton and lint cotton and the HG-1-1401A 1-million BTU/hr heater. More detailed information may be shipped to you under separate cover for your particular system. Steamroller Lint Conditioner The Steamroller is the most powerful lint conditioning system available.
Page 81: Hg-1-1401A 1-Million Btu/Hr Heater & Lint Slide Grid
A source for warm dry air is needed for the Steamroller. Hot air is also required for the Moisture Conditioning Condenser (not made by Samuel Jackson). The HU-SOUTHWEST cannot provide this dry hot air. A separate small heater for this, especially in cold climates is required. Samuel Jackson offers a 1-million BTU/hr heater for this job called the HG-1-1401A.
Page 82: Seed Cotton Conditioning Hoppers
Seed Cotton Conditioning Hoppers SAMUEL JACKSON CONDITIONING HOPPERS are used for restoring some moisture to seed cotton before ginning in order to preserve fiber quality. A Humidaire Unit provides the moist air. These special hoppers are installed between the conveyor distributor and the gin stand feeder.
