irrespective of year of manufacture. including rubber
connection, cable and bracket. Without circulation
pump.
Electrical heating cartridge type 2772 921
Shall be assembled vertically/horizontally in the heat-
ing system, or vertically on all Alde Comfort boilers,
irrespective of year of manufacture. including rubber
connection, cable, bracket and circulation pump.
ASSEMBLy INSTRuCTIONS
The space where the electrical heating cartridge is
located shall be dry. There shall be at least
10 mm free space between the electrical heating
cartridge and adjacent furnishing or other inflammable
items. The electrical heating cartridge shall be located
so that textiles, liquids and similar cannot come into
contact with the electrical heating cartridge.
An electrical heating cartridge mounted in a boat shall
be located in a dry area below deck. All other locations
shall be in an iP55-classed area.
When subsequently installing an electrical heating
cartridge, first empty the heating system of glycol
mixture and check that there is an earthed socket for
230 volts mounted within reach of the electrical heat-
ing cartridge's connection cord. Otherwise, a qualified
electrician shall carry out the installation.
Cut the pipe about 350 mm where the electrical heat-
ing cartridge is to be mounted. Between the electrical
heating cartridge and the pipe, a rubber connection of
special rubber is used and this shall be clamped tight
with clamps. Between the rubber connection and the
pipe, a thin layer of loctite 5923 shall be applied to the
joints as sealing agent.
Electrical heating cartridge 2772 911 is intended for
subsequent assembly of 230V circulation pump (the
article no. of complete assembly set is 2772 261).
With horizontal assembly, or where an air pocket could
form, a bleeder screw shall be mounted direct on the
incoming pipe (see fig. 1).
NB! The electrical heating cartridge must be
mounted according to the instruction for correct
placing, see pictures on page 5.
Inlet (fig 1a and 2a) and outlet (fig 2b and 2b) respec-
tively, see flow direction on pump housing.
The electric cartridge is equipped with an overheating
protection. This is triggered when the heating system
becomes overheated. Press the resetting button to re-
set the overheating protection. Fit the electric cartridge
so that access to the resetting button of the overheat-
ing protection is possible.
(fig. 1c and 2c).
The electrical heating cartridge shall be mounted on
a fixed bracket which is part of the assembly set or on
the Comfort boiler's attachment (fig 2).
ELECTRICAL INSTALLATION
12 V DC
in order for the electrical heating cartridge to function,
a 12-volt control circuit must be connected in.
A control cable is connected between the terminal
block of the electrical heating cartridge and thermostat,
or to the Comfort boiler's terminal block.
N.B. The chamfered side of the control cable shall
be mounted against the upper part of the casing.
On all Alde Comfort boilers (not type 2920), the pre-
mounted terminal block shall be cut off and adapter
cable 2772 130 used (see fig. 2).
The power of the electrical heating cartridge and the
circulation pump are selected either on the Comfort
boiler's control panel or on a separate control panel
(art. no. 2772 310) mounted in the fixtures. For connec-
tion of the electrical cartridge to the control panel 2772
310 (see fig. 3).
NB! Electrical cables must not be located next to or
on the warm parts of the electrical heating car-
tridge.
230 V ~
The electrical heating cartridge shall always be con-
nected to 230V earthed socket. Installation of a fixed
230V wall socket shall be carried out by a qualified
electrical engineer in accordance with relevant regula-
tions.
WARNING! 230V shall be separate from 12V.
FILLING THE HEATING SySTEM
The heating system shall be filled with a mixture of
water and glycol. Preferably use ready-mixed glycol
of high quality (with inhibitor) for aluminium heating
systems. When using concentrated glycol, the mixture
shall consist of 60% water and 40% glycol. if the heat-
ing unit is subjected to lower temperatures than -25 °C,
the glycol content shall be increased, but not to more
than 50%. Top up in the lPG boiler's expansion vessel
(see the boiler's instructions for use). Bleed and check
the fluid level in a newly filled heating system after
some days, or after the system has been operating.
NB! never allow the heating system to be standing
empty of glycol mixture. The glycol mixture is very im-
portant as it has a lubricating and rust preventive effect.
INSTRuCTIONS FOR uSE
The power is selected with the changeover switch on
the control panel, 1kW or 2kW (art. no. 2772 310).
On the Comfort boiler, use changeover switch to select
whether the12V or 230V circulation pump (not 2772
911) shall be used.
For more detailed use of different control panels, see
the instructions for use for the lPG boiler.
IMPORTANT
The electrical heating cartridge must not be started
without glycol mixture. If an electrical heating
cartridge with circulation pump is mounted on the
back of a Comfort boiler, the pump must not be
started until all the air has been bled out. Regu-
larly check the connection cord for any indication
of damage or ageing. A damaged cord must be
replaced immediately. Also check that there is an
earth connection between the earthed power point
and the electrical heating cartridge. When using
the 230V circulation pump, continual operation is
recommended for maximum life.
WARRANTy
Alde's warranty applies for one year from date of deliv-
ery, and only covers materials or manufacturing faults,
provided that these instructions have been followed.
NB! Only use genuine parts from Alde as spare parts.
