- All bolts must be tightened before first start of
system.
- The pipes must be fixed to the building structure
to ensure that they can not move or be twisted.
- In the case of the pump operate with a suction
head, it is mandatory to install a foot valve (cone) of
adequate size.
- If the pressurization system is installed on a base
with vibration dampers, joints compensation must
always be installed in the collectors. This
procedure is important to prevent the
pressurization system becomes "hung" in the
pipeline.
5. Compnsation joints
The compensation joints are used in order to:
• Absorb the expansions / contractions of the
tubing caused by the temperature of the liquid
constantly changing
• Reduce the strain with respect to pressure surges
in pipes
• Isolate the noise produced by the mechanical
structure of the pipe (just compensation joints of
rubber bellows).
NOTE: The joints of compensation can not be
installed to compensate inaccuracies in the
pipeline, such as the displacement of the
central holes.
- Install joints offset a minimum distance of 1 to 1 ½
times the nominal diameter of the orifice of the
suction and discharge manifolds. This prevents
the development of turbulence in compensation
joints, resulting in better suction and a minimum
loss of pressure on the discharge side.
- The pipes must be fixed so as not to press the
compensation joints and pump. Follow the
instructions of the supplier and to disclose them to
the consultants or installers.
6. Electrical Installation
- Before making connections take in attention:
Wiring must be performed by a professional
according to local regulations.
Make sure the power is turned off and locked
Make sure that the system is suitable for power
supply which will be connected.
Follow the wiring diagram in Annex 1
