1) GENERAL CONSIDERATIONS

DANGER: Before proceeding to install the product, read these instructions carefully.
WARNING: Guard with care this manual for consultations after the first installation
Pressure sets are used with water supply systems to increase and maintain pressure. These systems are
installed primarily in residential buildings, hospitals, hotels and industrial buildings.
CPE sets are conventional sets with constant speed pumps, controlled by ECD controller. CKE pressure sets,
with regulated speed pumps, are designed to deliver water at a constant pressure, controlled by a ESD
controller.
Using a pressure transducer, the ESD/ECD receives a signal that is proportional to the installation's pressure.
Depending on the scheduled start-up or shutdown pressure, the set's pumps start up and shut down in a
staggered and alternating fashion.
CKE
There are 2 types of CKE sets: with auxiliary pumps "on-off" and with variable speed pumps.
In booster sets with variable speed pumps, all the electric pump motors are equipped with ESD inverter, and
each inverter communicates with the others. The start-up of each motor and the rotating speed is
determined by the water consumption at any given time. The operation mode is alternated, for each
activation of the booster set, the order of start pumps is random. In booster sets with auxiliary 'on-off'
pumps, the main pump is equipped with a ESD inverter and the auxiliary pumps are equipped with ELV
controler for starting and stopping the pumps. The entire set is controlled by the ESD. The operation mode
is alternated, for each activation of the booster set, the order of start pumps is random.
In both types, the pre-selected pressure is constant.
The same set can be powered at 50Hz or 60Hz.
With this type of regulation it is much easier to control energy usage than with unregulated systems.
Another advantage of CKE booster set is that it reduces pressure surges and softens peak currents, thereby
prolonging the life of the pump.
CPE
The ECD control panel provides direct control of one or two pumps. If connected to 2 ELV panels, you can
control the pressure booster sets of 3 or 4 pumps.
These units are made of the highest quality materials and undergo strict testing and controls.
WARNING: Adequate compliance with the installation and operating instructions, as well as the
electrical connection diagrams, ensures proper equipment functioning.
DANGER: Not following the instructions in this manual can lead to motor overloads, diminishment in
technical characteristics, reduction of equipment life and all types of other consequences, for which
we disclaim any liability.
