3.3 Assembly and greasing of the O-rings:
If the O-rings of the cover have not been greased yet, or when the grease is
contaminated or the rings are damaged and need to be replaced: remove the four O-
rings from their seats, clean them with a lint-free cloth, or use a neutral soap.
Take a small amount of oxygen compatible grease and spread the grease onto the
ring by pulling the ring between thumb and forefinger. Be sure that the grease is
spread equally over the ring. Be careful not to use too much grease as the excess will
be pushed away when replacing the cover onto the canister.
A small amount of grease can also be put onto the inside of the cover after cleaning it
first.
Warning: use only oxygen compatible grease for all O-rings on the rEvo!
The O-rings of the breathing hose connectors can also slightly be greased without
removing them (when they are not contaminated: check for sand or dirt traces first, if
contaminated remove and clean as above).
3.4 Packing the scrubbers:
Unscrew the handle of the scrubber, take out the spring, remove the grid and the
mesh (be sure not to lose any parts). Throw away the used scrubber material and
remove the remaining dust by slightly tapping on the canister..
Be sure to take into account local environmental regulations regarding toxic
waste!
Make sure the filter stays inside the canister.
Packing the canisters is done best in the open air to avoid scrubber dust. If there is
wind be sure to be upwind so that the wind blows any dust away. Position the canister
on a horizontal surface: pour the absorbent from a height of approximately 20-30 cm
into the cassette. Let the wind carry away the absorbent dust. Keep filling until a
small pyramid of absorbent is formed in the canister (keep 1 cm free from the top of
the canister).
