Installation - Truper PRE-1I Manual

Installation

Mounting
• The pump shall be installed in a dry place sheltered from
outdoor weather but that allows the flow of air for its
adequate ventilation (A). Ambient temperature shall not
exceed 104 °F.
• Use bolts to fix the pump into a concrete base to avoid
vibration (B). The pump shall be installed horizontally to
assure good functioning.
C
• Pipes in the suction and pressure lines shall be
supported to the wall or floor to prevent transmitting
E
tension into the pump body (C).
• Use care to boy damaging the pump and / pipes, due to
excessive tightening of the joints.
F
Suction Line (inlet)
• The diameter of the suction pipe should not be
smaller than the diameter of the pump water inlet.
• If the suction height exceeds 13 ft, use a larger
diameter pipe. The suction pipe must be
completely airtight, and its end should be
A
submerged in the water at least half a meter, where
it is recommended to install a foot valve (D). The
pipe should be perfectly vertical and bend at a 90°
angle towards the pump water inlet.
CAUTION
Failure to follow these instructions may result in
airlocks and bubbles that interfere with the pump's
G
performance.
Pressure Line (Outlet)
• A gate valve (E) should be attached to the outlet
pipe to adjust the required flow rate and pressure.
• It is recommended to install a check valve (F)
between the high-pressure water outlet of the
pump and the gate valve to prevent the
unexpected return of water columns exceeding 20
90°
B
meters.
• Wire the system as indicated on page 8.
C
• Connect the automatic control to the power
outlet (G).
