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.
