Connection Lubrication
Connections with O-rings must be properly lubricated. The following instructions describe the
method and locations for lubrication.
Six packets of silicone lube are supplied. One packet should be completely used to lubricate the
O-ring contact surfaces in the 3 manifold ports and 2 RO membrane locations (Figure 9). Follow
Figure 10 and lubricate the filter seat and the flat surface below the threads for the 3 sump
locations. Use a complete packet of silicone for each sump location.
Note
: To properly lubricate the O-ring contact area, a film of clean silicone grease is applied.
The film should cover all of the surface area that the O-ring will slide over and seal with. Do not
use grease containing petroleum products.
The table below shows the coding system for the fitting connections. Each fitting has a unique
“keyed” socket on the manifold. Each fitting also has a graphic symbol moulded into the elbow
with a corresponding symbol on the manifold.
