Unpacking the Drying Hopper System
Components
Because of their size and shape, and the multiple sizes in which the hopper is available,
the components of the drying hopper come packaged for shipping in the best available
manner. The hopper components include, depending on the model and options ordered:
•Drying hopper
•Hot air drying circuit blower
•Dehumidifying drying circuit dryer
•Hot air and dehumidifying drying circuit heaters (HTC, HP or GasTrac)
•Hot air and dehumidifying drying circuit cyclone separators
•Hot air and dehumidifying drying circuit

Hopper Installation Guide I1-3
Preparing for Installation
There are many options and pieces available for the drying hopper – look over the
entire manual and all pieces that were received before assembling the hopper to
make sure things are installed correctly.
The drying hopper system is easy to install if you plan the location and prepare the
installation area properly.
1 Make sure the installation area provides:
UGrounded power sources supplying the correct voltage and current for your
drying system components. Check each component’s serial tag for the correct
amps, voltage, phase, and cycles. Field wiring to each drying hopper component
should be completed by trained, qualified personnel. All electrical wiring should
comply with your region’s electrical codes.
UMinimum clearance for safe operation and maintenance. Refer to the component
manuals supplied with your specific drying system to determine minimum system
clearances needed for each system component.
UA mounting area that will support the weight of the fully loaded drying hopper,
floor stand, and the other drying system components. Refer to the specifications
supplied with your drying system for the weights of each system component.
UA source of water for the aftercooler in the dryer. (If equipped) The water source
must be tower, city, or chiller water at temperatures of 45° to 85°F {7° to 29°C}.
Refer to the specifications supplied with your system for the flow rate.
UIf the heat sources supplied with your Drying System are GasTracs, the
installation location must provide for exhaust flues and gas lines that meet all
applicable local, regional, and national codes. Ideally, each GasTrac should have
a dedicated vertical stack that exits the building through a rain-protected roof
penetration.
UMaterial and conveying lines installed. If you plan to use vacuum loaders to fill
the drying hopper, install conveying lines to the hopper location as well as other
utilities your loading system may require.

1-4 I Hopper Installation Guide
Positioning and Securing the Drying
Hopper Floor Stand to the Floor
WARNING: You are responsible for the structural integrity of this installation.
CAUTION: Care should be taken while moving the main drying hopper floor
stand and sections to ensure that no damage is done to these assemblies.
IMPORTANT: HAD systems - These are designed to have the HTC placed on
the back of the stand and connected to the hopper inlet, also located on the back of
the stand. The lid can be rotated to allow the standard drop tube to be on the left
or right of the back corner of the stand. If an optional cyclone is configured on the
order, it can be selected to be positoned left or right - it will only go in one way.
Dehumidifying drying systems such as W dryers pull moist air from the drying
hopper and circulate it through a dehumidifying dessicant wheel. These
systems use a HP style heater. This heater is a universal design and it can be
mounted to the tabs on the hopper on either the left or right side of the hopper.
The dryer would also be placed on that same side. If an optional cyclone is added,
it remains specific to the left or right configuration as determined in the purchase
order. The design ensures that the dryer, cyclone and HP should all be on one side
of the hopper.
It is important to fasten the hopper floor stand to a rigid floor structure. This will add
rigidity to the installation and help to prevent accidents during operation and maintenance
of the drying hopper.
Due to the varying size of Conair hoppers, we recommend that you:
•Follow all applicable local building and safety codes;
•Use anchoring techniques and hardware suitable for the size and weight of the drying
hopper; and;
•Do not install any hopper sections until the floor stand is secured to the floor.
1 Make sure the installation location for the hopper meets all provisions for clear-
ances, will support the weight of the fully loaded hopper, and provides space for
the installation of the other Drying System components. See the specifications
and drawings supplied with your system for details.
2 Using a forklift, hoist, or crane, move the floor
stand to its installation location.
3 Following all applicable building and safety
codes, secure the floor stand to the floor.
NOTE: The footpads on the floor stand have existing holes that
can be used for anchoring the floor stand depending on the local
building and safety codes.
NOTE: For Drying Systems
supplied with “small” hoppers,
the floor stand and cone section
may be pre-assembled at the
factory. If your floor stand and
cone section are pre-assembled,
follow the instructions in this
section for mounting the floor
stand then proceed to the
instructions in the “Installing
the hopper door, Upper, and
Lid Sections” section of this
manual.
Tools for installation
UForklift, hoist, or crane;
and
