2.5.11 Flex-Trunk Assembly 7 Ft/10 Ft
(See Figure 12 Flex-Trunk Assembly)
Remove the cover plate bolts and the cover
plate from either the right or left side of the SDF
cabinet. Using the same cover plate bolts, attach
the Flex-Trunk Adapter to the side of the SDF
cabinet. Be sure to place 1/4" diameter sealant
between the adapter and the cabinet, as shown
in Figure 12 Flex-Trunk Assembly. Next, attach
the Flex-Trunk assembly to the adapter, being
sure to install more 1/4" sealant between the
adapter and the Flex-Trunk assembly. With the
swivel base positioned as shown in Figure 12
Flex-Trunk Assembly, secure the Flex-Trunk to
the adapter using the four (4) 5/16 slotted
screws and lock washers. For the adjustment
and operation of the Flex-Trunk, see the
Installation and Operation Manual for the Flex-
Trunk IOM-40779-00.
2.5.12 Weatherhood Pack
(See Figure 13 Weatherhood Pack)
Remove the bolts and the rear access panel to
the SDF. If the SDF is equipped with an outlet
damper (see Figure 1 SDF-4 Phantom View), this
damper must be removed. The weather hood
cannot be used with the outlet damper. Also,
remove the lift lug from the corner of the cabinet
and replace it with the M-16 set screw provided.
Place 1/4" diameter sealant between the cabinet
top and the weatherhood. Position the
weatherhood over the cabinet outlet, as shown
in Figure 13 Weatherhood Pack, and attach the
weather hood to the cabinet using the four M-6
bolts provided. These bolts should be inserted
through the slots on the cabinet roof and
screwed into the weld nuts on the weatherhood.
Replace the rear access panel and bolts.

with threaded handles and a reinforcing
bar.
• Two 1/8" NPT couplings for dirty air (high
pressure) and clean air (low pressure)
fittings.

Options available with this SDF cabinet in
addition to the 12 x 12 explosion vents include:
• Explosion-Proof Motors.
• Aluminum Blower Wheels.
• NEMA 9 Explosion-Proof Solenoid
Enclosures.
• Checker board in remote enclosure with
unwired electrical only.
NOTE
• Explosion vent SDF units do not
contain an electrical compartment.
They are furnished from Torit
unwired.
• All electrical work must be done by a
qualified electrician according to local
codes.
