High Anchor/High Rigging; High Anchor/Low Rigging; Low Anchor; Weather And The Environment - 3M DEUS 7300 Manuel D'instruction

There are several ways to rig the DEUS 7300:
• High Anchor / High Rigging. Rig a DEUS 7300
device so it is positioned immediately over and
above the transition area. Make sure the place
of rigging will not result in damage to the rope
running through the 7300 device during use. (See
drawing above.)
• High Anchor / Low Rigging. Rig a suitable pulley
immediately over and above the transition area.
Make sure the place of rigging will not result in
damage to the rope running through the 7300
device during use. Rig the rope through the
pulley and down to the DEUS 7300 device at
ground level. Thread the rope through the DEUS
7300 device using a clear rope path that does not
result in friction between the 7300 device and
the pulley. Connect the DEUS 7300 device to an
appropriate anchorage.

• Low Anchor. Rig a DEUS 7300 device so it is
positioned immediately below the transition
area, over the area of descent. This rigging
makes transition difficult and risky and should
be avoided if at all possible. However, when low
anchor rigging cannot be avoided, the DEUS
7300 device will work better than other descent
devices because it is automatic and has the ability
to absorb some shock load.
"High Anchor / High Rigging" is generally simpler
and easier than "High Anchor / Low Rigging. " High
rigging also makes it possible to use 7300 devices
as reversible descent devices. The advantage of
"High Anchor / Low Rigging" is that the 7300 can be
used for "vector lifting" (an advanced technique that
requires special training).

weather and the Environment

All DEUS 7300 models are weather tight, which
means that they are designed to withstand incidental
contact with rain, snow, sun, sand and dirt. The units
are not designed to be submerged or cleaned with
high-pressure water or air. They will give better and
longer service if shielded from direct rain and if they
are not left exposed to elements when not in use.
Wet rope can be used, but will be "slower" than dry
rope.
Rope degrades when exposed to weather and
when allowed to get dirty. Also, dirty rope becomes
abrasive and will hasten wear of the DEUS 7300
in which it is used. Dirty rope can be washed with
mild soap and water, then rinsed multiple times
until water is clear. Rope that is wet and frozen is
dangerous to use until completely thawed.
