debris is not covered by warranty.
Common industry standard solutions are
> Extending roof eve beyond fan cone*
> Create a shelter a minimum of 6” above cone that
extends beyond the fan cone*
> Install snow guards according to manufacturers
recommendations
* The depth of J&D’s Magnum fan is 57”

-18 Serrated Flange Nuts from Bag 2 (Part 2), assemble the motor
mount brackets and venturi sections.
— Tighten only the bolts and nuts securing venturi sections.
— Holding the motor brackets up so the back side is flush to the
outside of the venturi sections, tighten the bolts and nuts
securing motor mounts and venturi sections.
2
Eye Bolt Installation:
• Stand the housing assembly up.
• Locate the dimple marks on the exterior of the venturi next to the motor
brackets.
• With a 13/64” drill bit drill out the (2) holes for the eyebolts.
3

• Assemble (2) SS Eyebolts and (2) SS Serrated Flange Nuts #10-24
from Bag 9 (Misc. Hardware)
— With the flange facing up, thread (1) Serrated Flange Nut onto
each Eyebolt as far as it will go.
• Insert each eyebolt nut assembly up through the hole drilled in Step 3
and secure with a SS Serrated Flange Nut #10-24 from Bag 9 (Misc.
Hardware), flange facing down.
• Using 3/8” wrench tighten each eyebolt assembly
NOTES:
- Turn the eyebolts so the opening of the loops are facing each other.
- Where the eyebolts are installed is now considered the TOP of
the fan.
4
Housing Side Panel Assembly:
• Start on a corner. With the front and back venturi section channels
inserted into the grooves of the housing side panel, slide the housing
panel across the top until it hits the center seam of the assembled
venturi sections.

(do not use the ones nearest the top or the bottom of the fan).
• Carefully lift off the rubber gasket over the striker plate groove and insert
(1) SS Damper Door Striker Plates from Bag 9 (Misc. Hardware)
at each location, angle the striker plate so the angle matches the fan
housing. To secure the striker plates, press the rubber gasket back down.
NOTE: No hardware is used to secure striker plates at this time.
12
Attaching Magnets to Damper Door:
• Identity the back and front of the damper doors. The magnet will be
attached to the back of the damper doors

Control Wiring Instructions:
• For dry contact ON/OFF control, connect dry contact from STOP/
RUN to signal ground.
- Closed contact is motor ON, open contact is motor OFF.
- Connect STOP/RUN wire to signal ground wire if dry contact
ON/OFF control is not used.
• Use the two 4-20ma IN wires for analog current speed control.
- Leave 4-20ma wires disconnected if not used, (less than
5.6ma is OFF).
• 0-10V in to signal ground for analog voltage speed control,
(less than 1V is OFF).
- Connect 10V OUT wire to 10V IN wire for no speed control,
(full speed).
• Use four conductor 26AWG (or heavier), shielded, dual twisted
pair, signal wire with drain wire from J&D control to Permanent
Magnet fan.
DISCONNECT POWER
