1 GENERAL POINTS
Read this documentation carefully before installation.
Installation and functioning must comply with local and national safety regulations in force in
the country where the product is to be installed.
The entire operation must be carried out in a workmanlike manner.
Failure to comply with the safety regulations not only causes risk to personal safety and da-
mage to the equipment, but also invalidates any right to warranty assistance.
Keep this manual in a safe place for further consultation even after the rst
installation.
2 APPLICATIONS
These electropumps (JONTRACT) are suitable for collecting rainwaters, waste waters con-
taing abrasives; ideal for DRAINING DOCKYARDS, shafts and emptying basements and ga-
rages.The pumps be also employed in moderately charged moving waters, irrigation plants,
and layer waters. When installed in wells or tanks, the pump, which is particularly silent run-
ning, avoids all problems related to suction and loss of priming.
The pump may be supplied with a oat switch cutting out operation automatically in the event
of an insufcient water level.
These pumps cannot be used in swimming pools, ponds or tanks in which people are
present, or for pumping hydrocarbons (petrol, diesel fuel, fuel oils, solvents, etc.) in
accordance with the accident-prevention regulations in force.
N.B. : The liquid employed in the pump for lubricating the sealing device is not toxic, but it
could alter the water properties (in the case of pure water) if there were any leaks in the seal.
3 PUMPED FLUIDS
The machine has been designed and built for pumping water, free from explosive substances,
and solid particles or bres, with a density of 1 Kg/dm3 and a kinematic viscosity of 1mm2/s,
and chemically non-aggressive liquids.
