DESCRIPTION

The D-StratTMSeries compact, high velocity destratification ceiling fans recirculate trapped air in high ceiling areas to lower heat­ing costs, extend life of HVAC equipment and promote the comfort of occupants. The compact, 540 CFM high-velocity fan oper­ates on only 30 watts and reduces the typical temperature differential of twenty degrees or more between ceiling and floor levels
by at least fifty percent. Unlike conventional paddle blade ceiling fans, D-Strat

TM

fans do not have visual moving blades. Discharge
velocity of 2000 FPM moves air effectively in a defined column to the floor level. Operation is quiet at 1.5 sones, ideal for office
areas and other noise sensitive environments. Costs less than 1/2 cent per hour to operate based on average U.S. electrical rates.
Compact design fits between roof trusses affording full access to upper level warehouse storage racking. A heavy-gauge swivel
mount allows fan to be aimed to avoid obstructions, concentrated at works areas or to dry floors in wet entryways.

GENERAL INFORMATION

Each DSF2 is electrically factory line tested before shipment. After opening carton, inspect thoroughly for shipping damage.
Impeller should rotate freely and all electrical wires and connections should be secured. If any damage is found, notify freight
carrier and your distributor immediately and file a concealed damage claim.

NUMBER OF DSF2 FANS NEEDED PER APPLICATION

Destratification fans are constantly fighting warm air that is naturally rising and concentrating
near the ceiling level. As ceiling heights increase so does the volume of stratified air and the
resulting temperature differential compared to the floor level. For this reason the number of
fans we suggest for a given square foot area increases as ceiling heights increase. Use this
table as a guide for the suggested number of DSF2 fans that should be installed to achieve
effective destratification for your application. Space fans evenly with an open path to the floor
from the fan discharge.

Divide Square feet of area to be served by the square feet in table based on ceiling height.
Round to closest whole number for suggested quantity of fans.

Example: 7500 square foot area with 16’ ceilings.

7500/1200 (16 foot ceiling height in table) = 6.25
This application would need 6 DSF2 fans.

DSF2 SPECIFICATIONS

Volts: 115 VAC Hz: 50/60 Amps: 0.24 Watts: 30 CFM: 540 Thermal Limit: 196°F (91°C)

Unit dimensions with mounting bracket: Height: 25 ½" Width: 12 1/8" Weight: 21 lbs.

NOTE: Each DSF2 includes a built in Thermal Limit that will deactivate the DSF2 in the event of fire in the space where the tem-

perature at the DSF2 reaches 196°F (91°C) or greater. This feature is in accordance with fire safety and insurance underwriting.
NOTE: Each DSF2 includes a Safety Cable that is rated for 100 lbs. The cable is required in some areas of North America where
seismic activity can occur. The cable is easy to install and should be used on all DSF2 installations.

INSTALLATION WARNINGS

READ INSTRUCTIONS CAREFULLY PRIOR TO INSTALLING THE DSF2. DO NOT DESTROY THIS DOCUMENT.

This DSF2 must be installed by a qualified professional installer in accordance with these instructions and the latest edition of the
National Electrical Code(NFPA #70) and any applicable State and Local Codes. If the DSF2 is improperly installed or misapplied,
a hazardous condition such as fire, electric shock or falling parts could result causing bodily injury and/or property damage.

DO NOT Connect Power to the DSF2 until it is completely installed. Disconnect Power prior to service or maintenance.

DO NOT use the DSF2 in hazardous environments where the electrical system could provide ignition to combustible or flammable

materials.

DO NOT use the DSF2 to exhaust or transport hazardous or explosive materials or vapors. Personal injury and/or property dam­age could result.

DO NOT handle the DSF2 without hand protection. The DSF2 has rotating parts and may have sharp edges. Hand

protection

should be worn when installing, operating and maintaining the DSF2.

DO NOT mount the DSF2 less than 7 feet above grade. The DSF2 has unguarded rotating components that potentially could
cause injury if contacted when operating. Mount the DSF2 at least 7 feet above grade and in consideration of occupants to insure
a safe installation.

DO NOT use the power cord of the DSF2 as a means of supporting the weight or position. Personal injury and/or property damage
may result.

DO NOT connect power supply until the DSF2 is completely installed. Disconnect power prior to service or maintenance

CAUTIONS

This DSF2 is designed to work in an ambient air condition between -10oF to +130oF (-23oC to +54oC). Operation of the DSF2
outside of this temperature range can destroy DSF2 and will void the warranty.

This DSF2 is factory wired for a grounded 120 VAC power outlet. Use one Tjernlund Products, Inc., p/n DSF2TR transformer per
DSF2 for single phase power supplies of 208, 220, 230, 240, 277 and 480 VAC applications.

Make sure to install the DSF2 away from furnaces and other high heat sources. Excessive heat may destroy the DSF2.

This DSF2 was designed to be used in sheltered applications only. Do not use in applications where moisture from rain or snow
may enter the DSF2. Damage to the DSF2 from moisture will void warranty.

This DSF2 has rotating components that are unguarded. Use care to insure nothing comes in contact with the moving

parts. Keep

the power cord and other ceiling level wiring clear of the DSF2.

To properly mount and support the DSF2, use the mounting hardware and secondary safety cable as directed. Make sure the
safety cable is connected to the roof truss or other load rated structural component. Follow the installation details found in these
instructions.

MOUNTING OPTIONS

The DSF2 can be mounted to the
bottom bars of a Bar Truss.

The DSF2 can be mounted to the bottom
angles of a Angle Iron Truss.

The DSF2 can be mounted to a rod or
pipe mounted between two Trusses.

The DSF2 can be mounted from a wall. (Installer
must provide proper bolts and wall anchors).

NOTE: Failure to follow these mounting instructions may lead to a DSF2 that will not stay in position and could possibly lead to
a dangerous mounting condition. After the mounting bracket has been installed firmly in place, the DSF2 can be secured to the
mounting bracket. Make sure to consider the routing of the power cord before mounting the DSF2 to insure the cord is routed
away from the fan’s moving parts and pivot points. Make sure to place one of the provided lock washers over each of the side
mounting studs before securing the DSF2 to the mounting bracket. Once the unit studs are inserted through the mounting bracket,
install the tooth nut to the studs with the teeth of the nut facing the bracket. The images below show the order of the hardware
before and after it is installed.

Once the fan is secured to the Mounting Bracket, tighten the (2) nuts with a 9/16" wrench or until the nuts apply tension to the
bracket. Pivot the DSF2 to the final mounting angle desired. Finish tightening the (2) nuts firmly to insure the fan does not move
during operation.

SAFETY CABLE INSTALLATION

The provided safety cable is purchased from a certified 3rd party. Follow the cable provider’s installation instructions. The following
images are to serve as aide to those instructions.
