Circulation Pump; Kits Available On Request - Immergas VICTRIX 24 TT 1E Instruction And Warning Book

1.26 CIRCULATION PUMP.

The boilers are supplied with a built-in circula-
tion pump with 3-position electric speed control.
The boiler does not operate correctly with the
circulation pump on first speed. To ensure opti-
mal boiler operation, in the case of new systems
(single pipe and module) it is recommended to
use the pump at maximum speed. The circulation
pump is already fitted with a capacitor.
Pump release. If, after a prolonged period of
inactivity, the circulation pump is blocked,
unscrew the front cap and turn the motor shaft
using a screwdriver. Take great care during this
operation to avoid damage to the motor.
By-pass Regulation (part. 24 Fig. 1-30). The
boiler leaves the factory with the by-pass open.
If necessary, the by-pass can be regulated to
system requirements from minimum (by-pass
closed) to maximum (by-pass open). Adjust
using a flat head screwdriver, turn clockwise
and open the by-pass, anticlockwise it is closed.
Total head available to the system.
A = Head available to the system at third speed with by-pass closed
A = Head available to the system at third speed with by-pass open
C = Head available to the system at second speed with by-pass closed
D = Head available to the system at second speed with by-pass open

1.27 KITS AVAILABLE ON REQUEST.

• System shut-off valve kits with or without
inspection filter (on request). The boiler is
designed for installation of system interception
cocks to be placed on flow and return pipes
of the connection assembly. This kit is very
useful for maintenance because it allows to
empty just the boiler without having to empty
the entire system. Moreover, the version with
filter preserves the functioning characteristics
of the boiler thanks to its inspectionable filter.
• System zone control unit kit (on request). If
the heating system is to be divided into several
zones (max. three), in order to interlock them
with separate adjustments and to keep water
flow rate high for each zone, Immergas supplies
zone system kits by request.
• Polyphosphate dispenser kit (on request). The
polyphosphate dispenser reduces the formation
of lime-scale and preserves the original heat
exchange and domestic hot water production
conditions. The boiler is prepared for applica-
tion of the polyphosphate dispenser kit.
• Relay board (on request). The boiler is prepared
for the installation of a relay card that allows
to increase the features of the appliance and
therefore functioning possibilities.

• Cover kit (on request). If installed outdoors in a
partially protected place with direct air intake,it
is compulsory to mount the appropriate top
protection cover for the correct functioning
of the boiler and to protect it from adverse
weather conditions.
• Cycloidal filter kit (on request). The magnetic
cycloidal filter is able to detect the ferrous
residues present in the system's water. Thanks
to the two cocks in the kit, it facilitates main-
tenance by cleaning the filter without having
to empty the circuit.
The above-mentioned kits are supplied complete
with instructions for assembly and use.
