TRANSPORTING DRYER
An optional Transport Kit is available for transporting
the unit by truck or tractor. Make certain to observe the
following safety precautions:
1. Recommended towing hitch height: 16 to 17 inches.
2. Hitch pin to be not less than 3/4 inch in dia. and
securely fastened so it will not come out in travel.
3. Use a safety chain.
4. Dryer must be towed empty and in accordance with
applicable state or provincial regulations.
5. Recommended tire pressure 55-60 psi (cold).
6. Maximum towing speed: 45 mph
7. After first 50 miles and every 200 miles thereafter:
a. Check temperature of transport wheels' hubs and
spindles immediately after stopping. Temperature
should not exceed 150
N
F. May be hot to touch, but
not melting lubricant.
b. Check wheel lug bolts; they are factory torqued at 115
to 120 ft/lbs. Retighten, if required, to approximately
90 ft/lbs.
INSTALLATION
SYSTEM LAYOUT — Consider the grain handling system
and location of storage bins and existing conveyors in
selecting the dryer site, to facilitate wet grain supply
and dry grain discharge to conveyors.
SITE SELECTION — The dryer is not to be operated
inside a building or in any area not permitted by elec-
trical codes, fuel installation regulations, or insurance
requirements. Do not operate in an area where com-
bustible material can be drawn into the fans. Maintain
the required minimum distance from other structures.
Refer to Fig. 1-1 for installed dryer dimensions.
FILLING POINT — Wet grain must enter the dryer at the
hopper at the rear end of the top auger, since the top
auger moves grain forward, toward the paddle switch
controlling the top auger (except for special build front-
loading units).
WET GRAIN SUPPLY — A wet holding bin may be utilized
to supply grain to the dryer, with gravity flow into the
dryer loading conveyor. Also, gravity flow from a
wagon or truck into a loading conveyor may be used to
fill the dryer. The top leveling auger will accept grain at
any rate up to its maximum capacity as listed in Table
1-1. In any case, the dryer must have a constant sup-
ply of wet grain. Auxiliary loading conveyors should be
sized to nearly match the capacity of the top auger, to
avoid air loss problems caused by underfilling during
high drying rate operations.
WET GRAIN LOADING — The dryer will automatically
start the top auger and any loading conveyor electri-
cally connected to the power terminal strip on the
power panel (see Section 8 - Wiring Diagrams). At the
beginning, dryer will completely fill, requiring approxi-
mately its full holding capacity. During drying, the top
auger will start and stop as required to maintain the
dryer full of wet grain.
LOAD TIMER — The unit is equipped with a top auger
Load Timer (inside ASC control box), to provide auto-
matic shutdown on wet grain outage, if the top auger
operates for a time exceeding the timer setting (field
adjustable).
DISCHARGE AUGER EXTENSIONS — Special dis-
charge auger extension kits are available, with an addi-
tional length of 1 to 10 feet (one foot increments) to pro-
vide dry grain discharge points at various distances
from the rear of the dryer, for direct discharge into ele-
vator legs or other conveyors. Extensions are avail-
able with either a solid or perforated tube.
AUXILIARY CONVEYOR OVERLOAD RELAYS —
Overload relays for the loading conveyor and take
away conveyor are factory equipped with heater ele-
ments as listed in Table 2-2 for motors on auxiliary con-
veyors. If other HP ratings are used, it is necessary to
change the heater elements to provide proper running
load protection for the motors.
DRYER FOUNDATION — The wheels are provided only
for transportation of the empty dryers to the site loca-
tion. Before assembling and installing the dryer, pre-
pare a level, secure foundation, with provisions for
dryer tie-down.
NOTE: If the dryer is to be equipped with an optional
Heat Reclaimer Package, also refer to instructions
included with the Heat Reclaimer. Heat Reclaimers for
C-2100A dryers include special dryer support struc-
tures which are intended for a conventional, flat type
concrete foundation.
DRYER PREPARATION
1. Remove Parts — Remove hopper and other parts
shipped inside dryer.
2. Wet Bin — Standard C-2120A models are equipped
with a Compact Wet-Bin. Refer to Bulletin CWB-01-2
for installation instructions. All other standard models
are equipped with a Fold-up Wet-Bin, which is installed
according to Bulletin WBF-01-2. Assemble the top
auger drive according to appropriate wet-bin installa-
tion bulletin.
3. Install Fill Hopper according to the appropriate wet-bin
installation bulletin.
4. Connect Electrical and Fuel.
5. Inspection & Testing — Thoroughly inspect dryer to
make certain all parts have been properly installed and
tightened. See FUEL CONNECTION and ELECTRI-
