Risk of material damage due to incorrect handling of
mechanical seals!

Material damage resulting from loss of seal function
— The O-rings of a mechanical seal must be installed without oil
or grease.
NOTE!
Spray cleaner (degreaser)
Generally, the seal faces equipped with O-rings can be inserted
dry.
— In order to ensure that they are free of grease and to aid
insertion, the O-rings can be sprayed lightly, depending on
their resistance, with a quickly-volatilizing spray cleaner
(degreaser) that leaves no residue.
