Step
1 - H-E-P TURNING VANE ASSEMBLY PREPARATION |
|
 |
- Cut turning vane product to specified project
requirements.
|
IMPORTANT TO NOTE:
- The H-E-P rail was specifically designed
with a slight lip on each side to allow room for the fastener
head.
- Assemble rail to vane with the lip facing
out. This assures a flush fit inside the duct.
- Airflow enters the turning vane at smoothly
rounded edge and exits off thin trailing edge.
-
Use provided “Airflow Arrow” stickers
as a directional guide on the vane before turning vane installation.
|
 |
- Prepare the HEP turning vane for assembly
by lining up the pre-punched side rail slots with the continuous
tubular channels in the vane.
|
 |
- Use the Aero-Dyne stabilizing jig for even
faster assembly.
|
|
Step 2 - QUICK
• EASY
• POSITIVE ASSEMBLY
|
 |
- Hammer the Aero-Dyne fasteners through top
of rail down into both continuous channels for a secure fit.
- Consider a palm nailer for faster assembly.
|
 |
- Duplicate task on opposite end.
|
|
Step 3 - H-E-P TURNING VANE INSTALLATION |
 |
- Before placing turning vane assembly
inside the duct, use shears to round off edges of rail for a
snug fit in the duct elbow.
|
 |
- Fasten assembly to duct wall per the latest
SMACNA recommendations.
|
|
H-E-P TURNING VANE INSTALLATION - UNEQUAL ELBOWS |
|
 |
H-E-P turning vanes can be
adjusted easily to the proper angle of attack, regardless
of the inlet and outlet dimensions of the elbow.
-
1.A
narrow strip (approx. 3/4 inch) is sheared from the
center of both top and bottom side rail pieces.
-
2.Vanes
are attached to them by the usual method of driving
fasteners through the slots.
-
3.All
of the vanes in the assembly then move together as the
correct alignment is made for the elbow, maintaining
the leading and trailing edges in an exactly parallel
relationship.
