ASSEMBLING INSTRUCTIONS

Please install it preferably below water level in vertical or horizontal position.
When installed above water level do it in such a way to avoid water discharge from the heater.
NOTE: This equipment is provided witch special clamps for wall or soil subjection.
When due to space limitations the heater cannont be installed as factory provided then the electrical components can be
turned 90º back or forth of the main water entry. (Fig. 3).
To modify it proceed the following way:
Loosen the screws that hold the resistance pipe to the box.
•
Turn it to the desired position and tie the screws again.

ELECTRICAL CONNECTIONS

It is recommended to install, previous to the heater, a differential switch (0,03A) and the fuses corresponding to each
power.
Cables should comply H07 RNF standards for each different power.
The cross section of the cables should comply the DIN VDE 0100 standard.
To connect the heater proceed as follow:
Open the box. (Fig. 4).
CONNECTION TO 400 V 3N~ (Fig. 5)
Push the supply cable through the mechanical seal. Connect the three phases to
the connections marked with L1, L2, L3.
Connect the Neutral cable to the connection N.
Connect the Ground cable to the connection ╧.
Close the box and set the differential switch into on position.
The green led should light on. The heater is ready to work.
400 V 3N~ HEATER ELECTRIC DIAGRAM. (Fig. 6)
CONNECTION TO 230 V ~ 1 N. (FIG. 7)
Assemble the Shunt (supplied) between connectors L1, L2 and L3.
•
Push the supply cable through the mechanical seal.
•
Connect the existing phases into any of the L1, L2, L3 connections.
•
Connect the Neutral cable to the connection N.
•
Connect the Ground cable to the connection ╧
•
Close the box and set the differential switch into "on" position. The green led should light on.
•

A R S
Anti-bounding security system. Most systems equipped with filtration can
suffer flow diminution due to filter saturation. In those cases the flow
switch control could send reiterative signals to the main switch and
damage it. The ARS discards the reiterative signals to protect the main
switch and increase its life.
