`
Before you unload powder from the IPC,
verify that the safety overpressure air line is
connected to the push-on fitting on the top
of the IPC container. (The safety overpressure
air line connects to two pressure switches in
the IRS. These switches detect potential
overpressure in the IPC during unloading.)
`
The pressure in the IPC normally cycles
between 0.7 psig and 0.8 psig while the IRS is
unloading powder from it. When an unload
cycle completes, the IRS clears the umbilical
which raises the pressure in the IPC to about
1.25 psi. The overpressure switches close all
the air valves for air flow from the IRS to the
IPC if the pressure in the IPC exceeds 1.8 psi.
IPC moving and storage safety
The IPC is designed to lifted and moved with a
pallet jack. Do not try to lift or move it manually,
especially when it is full. The IPC weighs 25 kg
(54 lb) empty and 125 kg (276 lb) full.
Always follow standard lifting practices (one
person per 23 kg (50 lb)) when moving any
SLS equipment or material. If you are not
accustomed to lifting this much weight, or if you
have back problems, do any or all of the following
to protect yourself: use additional people to lift
the items, remove mass to reduce weight, or use
a mechanically assistance such as a pneumatic lift
cart.
