This apparatus may be used by children 8 years
or older and persons with reduced physical, sen-
sory or mental capacities, or lacking experience
and knowledge, if they are supervised or receive
adequate training on the safe use of the appa-
ratus and understand the dangers.
Children should not be allowed to play with the
apparatus.
Children should not perform the ordinary clean-
ing and maintenance tasks without supervision.
J Be careful with hazardous liquids and environ-
ments.
K Caution! Look out for accidental leaks.
Do not expose pump to bad weather.
L Caution! Avoid icing.
Cut out power supply before servicing pump.
According to IEC 60730-2-6, this is a unit of inde-
pendent assembly, type 1B, for flood proof
installation in clean or slightly contaminated envi-
ronments. Pollution degree 2.
Pulse rating voltage 2500 V.
1. GENERAL INFORMATION
These instructions are designed to ensure the correct
installation and best use of our automatic constant
water pressure assemblies.
Read these instructions before installing the
unit.
Save them for future reference.
Correct pump operation is assured providing
the instructions on electrical connection, instal-
lation 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.
PRESSDRIVE 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.
