DECOMMISSIONING
STEADYPRES is live
but was manually put out
of service
INSTALLATION AND HYDRAULIC CONNECTIONS
COMPULSORY
• Install STEADYPRES in vertical position.
• If STEADYPRES is equipped with 3-point joints, do not use seals inside the three-point joint; there is already a sealing
OR there.
• Install STEADYPRES so that no harmful vibrations or mechanical stress arrive from the connecting tubing
• If the temperature goes under 0 °C, empty water from the STEADYPRES. Freezing of the water contained in STEA-
DYPRES would cause irreversible damage.
• It is indispensable for installation of an EXPANSION TANK system downstream of the inverter, especially if there are small
leaks.
– Accumulates pressurised water to reduce electric pump start-up to a minimum.
– Absorbs any excess pressure from the system.
– The minimum volume necessary, in litres (for membrane models) is approximately equal to 10% of the maximum flow
rate of the individual pump, expressed in l/min.
Example of standard application:
Qmax = 80 l/min V = 80 x 10% = 8 litres (rounded in excess to commercial size)
– Inflation (system with no load): 1 bar less in working pressure:
Example: Pset = 4 bar Pinflation = 3 bar
RECOMMENDED
• Install STEADYPRES in premises protected against external agents, ventilated, free of humidity or excess dust.
• Install STEADYPRES as close as possible to the electric pump
• If there are long cables between STEADYPRES and the electric pump (e.g. submerged electric pump), you are advi-
sed to apply a sine filter to protect the motor and the STEADYPRES from voltage peaks.
