PNEG-1472 L & B Series Field Installation 11
4. Installation Instructions
Site Selection
Consider the grain handling system and location of storage bins and existing conveyors when selecting
dryer site, to facilitate wet grain supply and dry grain discharge to conveyors. Other considerations are
prevailing wind direction, fuel and power supply locations, noise, and convenience of control location.
Foundation
The dryer should be placed on an 8” reinforced concrete slab located in a well-drained area. The slab
should be large enough to provide working area around the dryer, with a surface elevation consistent with
other parts of the grain handling and storage systems.
Legs
Centrifugal fan dryers are supplied with a standard leg set to support the dryer body 24” high as shown
in Figure 4A (optional 36” or 48” leg sets are availble). The dryer must be anchored to the foundation
with tie-down cables or placing anchor bolts through the leg supports into the fountion.
Dryer Assembly Procedure
Note: The front end of the dryer is defined as the fan-heater end. Left and right sides are as seen when
standing behind the rear of the dryer looking forward.
1. Leg Assembly
The standard leg support package shipped with this dryer is used to support the dryer frame at 24” high.
Three to five pairs of 24” leg assemblies are used under the dryer body depending on model, and two
pairs of 47.5” leg assemblies are used under the fan-heater module.
Assemble the 24” leg sets using item #2 leg weldment, item #3 cross beam 73.25” long, and item #5
triangular gusset using hardware items A and B. Snug the hardware hand-tight but do not torque until
positioned under dryer. Be sure to assemble the cross beam with the “C” channel opening facing down.
See Figure 4A.
Assemble the 47.5” legs in a similar manner using item #1 leg weldment and item #4 cross beam 64.5”
long. Be sure to orient legs so that the .25” dia. hole in the outer leg flange is 2.5” from the bottom. Set
the 47.5” legs approximately 57.5” apart on models 6034L (C2160B), 7534L (C2175B), 1038L
(C21100B), or 40.75” on models 3020L (C2130B), and 4026L (C2140B), then assemble (4) item #6
diagonal leg brace as shown. Only hand tighten hardware at this point.
2. Set Dryer Body Module
The dryer body may be placed on the dryer foundation by rolling it into position on its transports or by
using the supplied crane brackets for lifting. The wet bin must be assembled first. See wet bin assembly
manual (PNEG-1273) included in the dryer’s literature pack.
