1. GENERAL INFORMATION
Please observe the following instructions to achieve
the best pump performance possible and a trouble
free installation.
Read these instructions before installing the
pump. Save them for future reference.
These are multistage centrifugal pumps having
more than one impeller assembled in-line. The
same flow passes through each impeller but the
pressure increases each time, i.e. more impellers,
more pressure.
By using a foot valve on the suction pipe the pump
will rapidly self-prime when operated.
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 40ºC.
KIT02 is completely silent and are designed to
provide an automatic supply of clean water to one
or two dwellings.
It is a compact kit comprising a check valve,
electronic circuit and reset button.
It is designed to maintain constant pressure. It does
not permit the pump to operate without water and
avoids water hammering. It requires no preloading of
air or adjustment. It has a water reserve to prevent
the unit from being started by a dripping tap.
If water consumption is more than 1 l/min the pump
will operate continuously.
When the pump reaches maximum pressure the
unit automatically switches the pump off. Unit
selection must take into account the fact that the
differential must be over 0.7 bars.
Correct pump operation is assured providing
the instructions on electrical connection,
installation and use are strictly adhered to.
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.
