14. System protection
Failure to protect the system will invalidate the manufac-
turer's warranty. After the system has been installed the
cleansing and inhibiting procedure must be carried out as
follows:
Procedure:
1. Fill the system with cold mains water to the recom-
mended pressure 1.5 bar and check for leaks, then drain
the system thoroughly making sure all drain cocks are
fully open and that the system is completely drained.
2. Add Fernox Heavy Duty restorer through the header
tank or via filling loop at the recommended dose. One
bottle must be used as a minimum per dwelling. If you
are unsure of the correct dose rate, contact Fernox.
3. Re-fill the system and circulate the Heavy-Duty Restorer
prior to the boiler being fired up, then commission the
system in the normal way. The cleansing agent must
be in the system for a minimum 1 hour with the system
at normal operating temperature. A longer period of
time would be more beneficial to the cleansing process
especially if excess flux was used.
4. Drain and flush the system thoroughly to remove the
cleaning agent and any debris or contaminant. This is a
critical part of the cleaning process and must be carried
out correctly. Use a rinse test meter (TDS), such as the
Fernox CTM. The reading must be within 10% of the
mains ppm value.
5. Then add the Fernox Protector (Copal MB1 or Super
concentrate). This will protect against the formation
of scale, corrosion and microbiological growths. It is
crucial however, that for the protector to work correctly,
the system must be properly cleansed and flushed.
6. The label included within the Fernox Protector carton
should be completed and attached adjacent to the boiler.
7. We recommend inhibitor levels are checked on an an-
nual basis(usually during the service) or sooner if the
system content is lost. This should be carried out using
a Fernox inhibitor Test Kit.

15. Start-up / Commissioning
1. Ensure system is fi lled with water & vented.
2. Check if the appropriate system installation pressure is
reached
3. Switch the boiler on & set external controls to call for
heat.
4. Check the pump is set to the correct mode (see table
below). To do this, press
seconds. The LED's should signal an operating mode
at the place pointed by arrow.
5. If the LEDs are signaling a different operating mode than
recommended in the table below, set the appropriate
mode according to the following instructions: press
button for longer than 2 seconds, but less than 10 sec-
onds (LED's will start to fl ash), the pump then switches
to the settings mode. LEDs glows to indicate the cur-
rent settings. To change the settings of the pump in
accordance with the table below, you can set the right
combination of glowing LEDs by pressing the

the button for 10 seconds the pump will remember
button for 10 seconds the pump will remember this set-
ting and will exit from setting mode back to performance
view.
Note: holding
will enter the pump into key lock mode. This pre-
vents the user from altering the pump settings. To
remove the key lock the pump settings and allow
the pump settings to be changed, hold button
again for more than 10 seconds.
6. Ensure adequate fl ow through the boiler is reached. The
pump should self vent after a short period of running.
If necessary assist the venting process in the following
way; Warning the screw head in the centre of the pump
is not intended to be used to assist venting of the pump,
Damage to the pump internals may occur!
• close the isolation valve on the outlet,
• leave boiler running for 15 sec.
• open the isolation valve.,
7. Switch the boiler off.
8. Set the boiler to the required system temperature, see
the „Operating" section.

alarm status
If the pump has detected one or more alarms, the bicolored LED
1 switches from green to red. When an alarm is active, the LEDs
indicate the alarm type as defined in the table below. If multiple
alarms are active at the same time, the LEDs only show the error
with the highest priority. The priority is defined by the sequence
of the table. When there is no active alarm anymore, the user in-
terface switches back to operation mode.
