3.1 Checks to be performed whenever
starting the system
Each unit is pre-calibrated and tested in the factory according to a
suitable testing procedure. At the fi rst starting of the equipment, the user
should check as follows:
•
tightness of the various connections;
•
operation of the feed water circuit;
•
electrical connections;
Now water can be supplied to the system by opening the ball valve
suitably installed upstream. Wait until the complete fi lling and the
wetting of the input fi lter. Check on the pressure gauge if the supply
pressure is enough (1.5 bar).
3.2 Switching on and password entering
After electrical and hydraulic connections, switch the equipment on:
•
press the
button at least for two seconds. The display will show
"WAIT ON" for a few seconds (the time used by the equipment to
preset), then the current status is displayed.
•
pressing the arrows
and
information about the equipment operation (hour counter,
conductivity, ...).
•
press
to access the confi guration templates of the system.
•
enter the PASSWORD. The default value is "0077". To enter the password,
use the
and
arrows to move the cursor,
value. Press
to confi rm.
•
In this way you enter the list of items that can be modifi ed.
Caution: the parameters that can be modifi ed were already set at
commissioning, thus they do not need any change. Check that the
parameter confi guration complies with the default settings (as per
paragraph 3.8). Comply with the information of the manual and change
only the items listed here below.
3.3 Language selection
•
With equipment on, press
the system.
•
enter the password "0077" to enter the menu 01
•
Using
and
arrows, scroll to the menu 16 "LINGUA". Press
enter.
•
Scroll the available languages moving
the available ones (ITALIAN, ENGLISH, FRENCH, GERMAN, SPANISH).
Press
to confi rm.
3.4 First start
During the fi rst start, the purpose is wetting the membranes gradually,
without submitting them to the work pressure (5-6 bar) before they are
completely wet. Water must fl ow according to the main pressure for a
few minutes through fi lters and membranes, before the pump can be
operated.
Water produced during this stage cannot be used. It is advisable to
disconnect the permeate line and free drain all the water produced
during the fi rst start.

and
and select among
The procedure is the following:
1.
Disconnect the permeate line and temporarily convey it to a free
drain. Slightly open (one third) the feed water tap (suitably installed
upstream of the system), so that the water fl ow coming from the
network decreases to minimum.
2.
Switch the system on keeping pressed the
seconds. The display shows WAIT ON for a few seconds, then it shows
the main screen. Press
the system.
3.
enter the password "0077" to enter the menu 01. Now the equipment
functioning is stopped.
4.
Using
and
arrows, scroll to the menu 14 "SYSTEM TEST". Press
to enter.
5.
In this menu, all components are deactivated. You can decide to
activate/deactivate the individual components manually, using the
following buttons of the controller:
inlet solenoid valve
drain solenoid valve (NOT PRESENT)
fl ushing solenoid valve (ONLY ON ROC060)
pump
metering pump (NOT PRESENT)
6.
Press
to activate the fi ll solenoid valve: in this way, the N.C. valve is
powered and opens the circuit, letting water in.
FOR ROC060 ONLY: press the
this way, the N.C. valve is powered and opens additional drain, getting
an increased water fl ow and reducing the pressure diff erence between
upstream and downstream of the membranes.
Note: please note that it is always advisable to let the membranes
work at the lowest possible pressure (5...6 bar), above all during start, but
also during the system standard operation. This ensures a longer life of
the same membranes.
7.
Leave the system in these conditions for at least 10 minutes.
8.
Open again a little bit (two thirds) the water tap upstream of the
system, so that the water fl ow reaching the membranes increases.
Leave the system in these conditions for at least 10 minutes.
9.
Fully open the water tap upstream of the system, leave the system in
these conditions for 10 more minutes.
10.
Check that the charge valve (and the fl ushing one if present) are
still open. Now, activate the pump pressing the
inside the menu 14).
11.
Immediately check the working pressure of the membranes, on the
pressure gauge on the pump delivery side. Turn the adjustment
screw opening the by-pass valve of the pump (anticlockwise
direction), to reduce the pressure to about 2-3 bar. Leave the system
to
in these conditions for 10 minutes.
12.
Close the fl ushing valve if installed (pressing the
again the Bypass (clock wise direction). Make the working pressure
correspond to 5-6 bar, that is the standard operating pressure for a
WTS Compact with new membranes.
13.
Quit the menu 14 pressing
WTS Compact. Now the equipment is ready to work properly.
3.5 Checks and adjustment after start
After start, some checks for the correct operation of the WTS Compact
system must be made.
1.
Before connecting the permeate pipe to the expansion vessel, check
that the permeate fl ow rate is correct and the conductivity ranges
between the required values.
