7.2 Hydraulic connections
Flexible tube and tube cutter are supplied with the equipment to carry out hydraulic connections.
Quick connections:
The hydraulic connections are made by means of a System known as Quick Connection (QC): Simply insert the
tube until it stops, and it is connected.
To disconnect the tube, first press the central washer of the QC device inwards while pulling the tube in the
opposite direction.
Important: Tubes connected with Quick Connection must have a clean cut, perpendicular to the length of the
tube. The tube section inserted in the connection will be smooth, with no abrasions. Any bevel cut-out or a
damaged tube termination will make the connection imperfect and lead to water leakage.
a. Water inlet: The water inlet will be provided with a stopcock with BSP male threads of 1/2". Thread the connection piece
supplied.
Do not use Teflon for this connection (the connection is fitted with a rubber seal).
If due to highly polluted inlet water it is necessary to install and additional pretreatment, the connection
sequence will be:
Feed water - Enters additional pretreatment - Exits pretreatment - Enters the equipment. All connections are
quick type.
b. Drainage: The drainage point will be at a maximum 3 m far. The Rejection tube must be positioned to
ensure that it cannot move from its position by a flange or by inserting it approximately 30 cm into the drain pipe.
The Rejection tube is connected with a quick connection "Rejection" located at the rear of the equipment.
Using the drain flange:
Drill a 6.5 mm hole in the drain pipe where the Rejection tube is to be inserted.
Place the pad over the hole and the drain flange on top, gripping the pipe. Secure it by tightening the screws on both sides.
Insert the Rejection tube 5 cm, through the flange.
Secure the Rejection tube with the drain flange nut.
c. Tank level: The tank level is connected at the rear fitting "0"
