1. Introduction
Thank you for your purchase. Follow the instructions in this manual for safe use of this fan and heater.
Following proper operation and maintenance will help to keep the fan and heater running in optimal
condition.
Keep this manual handy for frequent reference and to review with new personnel. A sign-off form is
provided on the inside front cover for your convenience. If any information in this manual is not
understood or if you need additional information, please contact AGI or your representative for
assistance.
This manual should be regarded as part of the equipment.
• Drying capacities represent Westeel’s best estimate of results based on a combination of actual
field data and computer analysis.
• Capacities will vary depending on outside temperature, humidity, initial grain moisture, initial grain
temperature, crop maturity, crop variety, cleanliness of the grain, test weight, operating
temperature, equipment set up, cooling air, drying vs. cooling zones, etc.
• Hot grain discharged from the bin will dry an additional 1.5% -2% when properly cooled.

2. Safety
2.1. Safety Alert Symbol and Signal Words
This safety alert symbol indicates important safety messages in this manual. When you see
this symbol, be alert to the possibility of injury or death, carefully read the message that
follows, and inform others.
Signal Words: Note the use of the signal words DANGER,WARNING,CAUTION, and NOTICE with the safety
messages. The appropriate signal word for each message has been selected using the definitions below as a
guideline.
Indicates an imminently hazardous situation that, if not avoided, will result in serious injury or
death.
Indicates a hazardous situation that, if not avoided, could result in serious injury or death.
Indicates a hazardous situation that, if not avoided, may result in minor or moderate injury.
Indicates a potentially hazardous situation that, if not avoided, may result in property damage.
2.2. General Product Safety
Read and understand all safety instructions, safety decals, and manuals and follow them.
• Owners must give instructions and review the information initially and annually with
all personnel. Untrained users/operators expose themselves and bystanders to
possible serious injury or death.
• Use for intended purposes only.
• Do not modify the fan and heater in any way without written permission from the manufacturer.
Unauthorized modification may impair the function and/or safety. Any unauthorized modification will void
the warranty.
• Follow a health and safety program for your worksite. Contact your local occupational health and safety
organization for information.
• Always follow applicable local codes and regulations.
EASYDRY® – FAN AND HEATER 2. SAFETY

12 250051 R6
2.3. Fan Safety
• Keep away from fan impeller/blade; high suction can pull a
person toward the inlet. Contact with an unguarded
impeller/blade will cause severe injury.
• Keep the inlet screen in place at all times.
• Remove foreign material from the fan inlet before operating.
• Do not operate the fan if there is excessive vibration or noise.
• When the power is locked out, fans can still be dangerous
because of potential “windmilling.” Always block the
impeller/blade before working on any moving parts.
2.4. Heater Safety
Fire and explosion hazards, as well as carbon monoxide poisoning could occur if the heater is
misused. To avoid serious injury or death:
• Shut off and lock out or disconnect power and close valve at
gas source before inspecting or servicing the heater, or when
not in use.
• Do not operate the heater if not properly connected to an
aeration fan.
• Use the heater only with the gas types intended, connecting
alternate fuel sources to the heater can result in fires.
• Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
• Do not remove covers, touch, or service internal components
during operation.
• After burner shutoff, allow the fan to run for five minutes
before removing cover(s).
• Do not use the heater where a high concentration of grain
dust or flammable liquids or vapors exist, such as milled grain
dust.
• Never allow anyone to enter the grain bin when a fan and
heater is operating. Gases given off by the burner (including
carbon monoxide and carbon dioxide) could cause death.
• Never use the heater to heat a building, shed, barn, etc.
because of the hazards posed by the flame and by the output
of carbon monoxide.

Inspect the power source(s) before using and know how to shut down in an emergency.
Whenever you service or adjust your equipment, make sure you shut down your power
source and gas supply and follow lockout and tagout procedures to prevent inadvertent
start-up and hazardous energy release. Know the procedure(s) that applies to your
equipment from the following power sources.
For example:
WARNING
• De-energize, block, and dissipate all sources of hazardous energy.
• Lock out and tag out all forms of hazardous energy.
• Ensure that only 1 key exists for each assigned lock, and that you are the only one that holds that key.
• After verifying all energy sources are de-energized, service or maintenance may be performed.
• Ensure that all personnel are clear before turning on power to equipment.
For more information on occupational safety practices, contact your local health and safety organization.

4. Preparation
4.1. Check Shipment
Inspect the fan and heater and accessories on receipt to ensure that all items have arrived and that none are
damaged.
A few basic items to check:
• Ensure there are no loose items or debris that can be drawn into the fan or dislodged by the fan discharge.
Check the interior of the fan as well.
• Turn the fan impeller/blade by hand to check for binding.
• Check the tightness of all nuts and bolts.
• Verify that the supply voltage is correct.
Report missing or damaged parts immediately to ensure that proper credit is received from Westeel or your
distributor/dealer, and to ensure that any missing parts can be shipped quickly to avoid holding up the
installation.
Important
Do not use damaged components.
4.2. Before You Begin
Before you assemble the fan and heater:
• Familiarize yourself with all the sub-assemblies, components, and hardware that make up the equipment.
• Have all parts and components on hand, and arrange them for easy access.
• Separate the hardware (bolts, nuts, etc.) and lay them out into groups for easier identification during
assembly.
EASYDRY® – FAN AND HEATER 4. PREPARATION

5. Installation
Before continuing, ensure you have completely read and understood this manual’s
Safety section, in addition to the safety information in the section(s) below.
5.1. Installation Safety
• All installation and servicing operations are to be carried out by qualified technicians.
• The equipment shall be installed in accordance with applicable local codes and regulations.
For Canada: Natural Gas and Propane Installation Code, CSA B149.1 and the Propane
Storage and Handling Code, CSA B149.2, or applicable provincial regulations should be
carefully followed in all cases. Authorities having jurisdiction should be consulted before
installations are made.
• Never install the heater for use in a building, shed, barn, etc. because of the hazards posed
by the flame and by the output of carbon monoxide.
• Do not take chances with safety. The components can be large, heavy, and hard to handle.
Always use the proper tools, rated lifting equipment, and lifting points for the job.
• Always have two or more people installing the fan and heater.
• Make sure you have sufficient lighting for the work area.
• Tighten all fasteners according to their specifications. Do not replace or substitute bolts,
nuts, or other hardware that is of lesser quality than the hardware supplied by the
manufacturer.
5.2. Electrical Connection
Installation Notes
• The heater control box requires 3-wire single phase power - 120V “hot” L1, 0V neutral L2, and ground.
• The heater starter box MUST be electrically interlocked to the fan to ensure operation only when the fan is
running. Westeel fans equipped with starters include an auxiliary electrical contact for this purpose. Fans
equipped with a VFD do not interlock with the control box.
• Remove jumper 6–7. Install the thermostat control wire here. See Section 5.2.1 – Wiring Diagram on page
23.
• Westeel recommends that all fan/heaters are connected to a ground rod. Check previously installed units for
proper grounding.
• The customer is responsible for supplying the materials and labor to install:
– A properly-sized lockout type disconnect box with fuse or breaker protection for EACH fan and add-on
heater.
– Properly-sized service line.
– Proper grounding protection.
Important
When installing new wires, replace wires with the original wire type supplied with this fan/heater.
Always replace wires with original type and/or an equivalent wire type.
