4.2. Water inlet installation (Figure 13 & Figure 14)

The water supply input consists of two parts; a brass ball valve (Figure 5) and an

adaptor (Figure 4). The brass ball valve must be screwed to the adaptor using

sufficient Teflon on its thread, as shown in the figure below.

b. Turn off the water supply at the point where you are installing the ultrafiltration

system.

c. The water supply input is designed to be used with hoses with a ⅜" connection.

Insert the water feed adapter with the brass ball valve between the cold water

supply and the hose. (Never install a hot water connection as the ultrafiltration

system will be damaged). Make sure that the brass ball valve is closed.

The hydraulic connections should follow the contour of the surface cho-

sen for installation so that the tubes do not get mixed up or tangled. Leave a

sufficient length of tube to ease moving the system during future maintenance.

Here are the steps to follow to make the hydraulic connection:

a. Connect the ⅜" tube (Figure 3) to the water supply inlet (Figure 5).

b. The other end of the ⅜" tube should be connected to the pressure re-

ducer inlet (figure 10); to do so, you must remove the blue security clip

which is on the inlet of the pressure reducer and insert the tube fully.

Once you have introduced the ⅜" tube, replace the ⅜" plastic clip. (The

pressure reducer has a sticker with an arrow that indicates the way the

water should flow, then the pressure reducer inlet will be the way the ar-

row is pointing)
