Support Information
The Chore-Time TURBO® Cone & Grill Fans are designed to be used as exhaust fans in corrosive environments.
The primary components are made from plastic or stainless steel materials. Using this equipment for any other
purpose or in a way not within the operating recommendations specified in this manual will void the warranty and
may cause personal injury.
This manual is designed to provide comprehensive planning, installation, safety, operation, and parts listing
information. The Table of Contents provides a convenient overview of the information in this manual. The Table
of Contents also specifies which pages contain information for the sales personnel, installer, and consumer (end
user).
Important!
Chore-Time Equipment strongly recommends that a good alarm system should be installed in
confinement buildings to warn of power failure and high temperature.
Chore-time Equipment also recommends that an alternate power source be available for confinement
buildings in case of power failure.

1" [25.4] 
4' [1 219]
• Optional equipment contains necessary instructions for assembly or operation.
• Major changes from the last printing will be listed on the back cover.
• This Planning Symbol is used in areas where planning needs to take place before
construction continues.
• Very small numbers near an illustration (i.e., 1257-48) are identification of the graphic,
not a part number.
Safety Information
Caution, Warning and Danger Decals have been placed on the equipment to warn
of potentially dangerous situations. Care should be taken to keep this information
intact and easy to read at all times. Replace missing or damaged safety decals
immediately.
Using the equipment for purposes other than specified in this manual may cause
personal injury and/or damage to the equipment.
Safety–Alert Symbol
This is a safety–alert symbol. When you see this symbol on your equipment, be alert
to the potential for personal injury. This equipment is designed to be installed and
operated as safely as possible...however, hazards do exist.
Understanding Signal Words
Signal words are used in conjunction with the safety–alert symbol to identify the
severity of the warning.
DANGER indicates an imminently hazardous situation which, if not avoided, WILL
result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
CAUTION indicates a hazardous situation which, if not avoided, MAY result in
minor or moderate injury.

Planning the Installation
Carefully plan the installation.
Dimensions are provided for the 36" TURBO® Fans with Cones (Figure 1) and
without Cones (Figure 2). Be sure to allow enough space to install fans without
interfering with other fans or equipment that may be installed at a later date.
Note: See page 8 for framed opening size.
Important: Cones are wider than the actual opening cut into wall. Thus,
dimension "3" must be no less than that listed in chart below.

hardware package.
Note: If an Aluminum Shutter will be installed, route the motor cord through
the Rubber Grommet—included in the hardware package see Figure 7.
Some installations may require an exit hole for the motor cord to be drilled in the side
of the Shroud. These installations must have electrical wires routed through conduit.
Note: Make sure the conduit or wires do not interfere with the Fan Blades or
Shutter operation.

Shutter Installation
Plastic and Aluminum Shutters are available for the 36" Fans. Installation is
identical except where noted. See below.
1. If you have a Plastic Shutter—cut a 3/8" slot in the upper left flange of
the Shutter frame in order to route the electrical cord out the back.
2. If you have an Aluminum Shutter, route the electrical cord through the
notch in the top of the Shutter Frame. Make sure the Grommet is installed
correctly in the notch in the Shutter Frame. (See Figure 9 below)
3. Position the Shutter, centered in the Fan Shroud, and rotate the Shutter
Clips to lock the Shutter in place. Check the Shutter for proper
operation—the shutter must be able to open and close freely without
obstructions.
Note: Make sure the electrical conduit and wire does not interfere with
the Fan Blades or Shutter operation.

Maintenance
Maintenance 36" Belt Drive
14 MV1680H
Service and maintenance of fans should be done only by a qualified technician.
Disconnect Power prior to maintaining or cleaning the fan! The fan may start
automatically causing injury or death.
1. Keep the fan clean for maximum life and performance.
2. Clean Shutter, Cone and Shroud for maximum life and performance.
3. The Fiberglass Fans are shipped with the Danger Decal fastened to the Fan
Shroud. Always keep the Decal clean and readable.
If the Decals becomes damaged or unreadable, order replacement Decals
immediately.
Clean the Shroud at the approximate location where the Decal will be placed.
Peel the backing off the Decal and affix it to the Shroud.
4. Periodically check the V-Belt. If necessary, adjust the spring tension to prevent
belt from slipping.
Fan Bearing Lubrication
• Grease zerks are provided for lubrication on the fan shaft bearings.
• Lubricate the fan every 2-6 months or whenever these components get wet.
• Disconnect power to the fan before lubricating.
• Clean the zerk before lubricating to prevent contamination from entering the bearing.
• Use a high quality lithium based, NLGI #2, grease such as Shell Gadus S2 V100 2. Do not use incompatible
greases containing aluminum, barium, calcium, bentonite clay or polyurea thickeners.
• Slowly rotate the fan shaft by hand while slowly applying the grease. Rapidly applying grease to a stationary
bearing can damage the bearing seals.
• Apply about .10 oz (2.8 g, 3.1 cc) of grease at a time or until a slight amount of grease can be seen purging
from the seal.
