2) INSTALLATION

2.1) Procedure

* Position the boiler squarely on the prepared base
* Fit the correct accessories to the boiler connections
* Connect the boiler to the pipework system
* Connect the boiler to the isolated electrical supply
* Fill the boiler with fresh, clean water
* Check that the immersion heaters are electrically isolated from the
boiler. If the isolation is less than 2mega-ohms, the bridge must be

found and rectified.
* Check the operation of the main control panel isolator, and of the
overloads serving the immersion heaters
* Check the operation and the correct direction of rotation of the
circulating pump
* Check, with the circulation pump stopped, that the water flow switch
over-rides the immersion heaters through their relays and also brings
on the relevant alarm light
* Check the setting and operation of the immersion heater step controls
* Switch off the immersion heaters using the main control panel isolator
* Check that all the cartridge fuses are sound
* Double check that all the immersion heaters receive the common
voltage. Repeat the check after several hours run. Any defect in

voltage can destroy the heaters and invalidate the guarantee.

2.4) Precautions

The Multi-elec Compacte requires an installation conforming to

 89.336/EEC Directive (electromagnetic compatibility)
 73/23/EEC Directive (low voltage)
 92/42/EEC Directive (performance)

2.5) Boiler room arrangements

The Multi-elec Compacte must be installed
 In an adequately-ventilated boiler room with ambient temperature below 30degC

And relative humidity maintained between 30% and 80% and where condensation
does not occur

 In a non-corrosive atmosphere
 In a non-explosive atmosphere
 Where there is good access to the boiler position for installation and maintenance
 Where there is good access for delivery, off-loading and positioning
 Using similar materials in the pipework, and avoiding materials leading to electrolytic

action and system deterioration

The Multi-elec Compacte is not suitable for external installation

2.6) Commissioning

 The boiler must be completely full of water before the heating elements are switched

on. To ensure 100% filling, manual and automatic vents must be in effective positions
where complete air clearance can be guaranteed.

 The boiler can be filled with water by connecting a fill hose to the boiler drain valve

and partly opening the valve.

 The boiler safety valve can also be used firstly to vent the boiler at filling and,

secondly, ensuring the blow-down facility of the valve is clear in case of use.

 Commissioning is recommended by Atlantic 2000 or an authorised engineer for

Atlantic equipment.

ELECTRICAL CIRCUIT

 The Compacte electric boiler must be provided with 415volts and

without neutral wiring

 The electrical wiring cables must be sized by a qualified electrician in

order to conform
to BS C 15100 and satisfying load, length of run and prevention of short
circuit.

 The installation must be tested for automatic power failure in the

event of emergency
power cut, heater lock-out or error in the neutral layout.

 All electrical equipment shall satisfy IP21/IK08 Class 1
 The immersion heaters shall only receive electrical power if they are

fully immersed in water; otherwise the guarantee on the heaters will
not apply

ALL ELECTRICAL WIRING MUST BE CORRECTLY EARTHED

3.6) Alarm Signals

On Alarm, light (7) shows and the following messages appear on (1)
< PFO > Lock-out or power cut
< HA > High temperature lock-out
< LA > Low temperature alarm

4) DELIVERY and OFF-LOADING

It is recommended that the COMPACTE electric boiler is transported and, if necessary,
stored on the pallet on which it is delivered from the factory.
If temporarily stored, the surroundings should be maintained at temperatures below
80degC, and without condensation at relative humidities between 30% and 80%

Manhandling the COMPACTE electric boiler into position requires :-

(a) Qualified, skilled manpower
(b) Use of a pallet trolley or a fork lift truck
(c) Use of the lifting eyes provided on the boiler and tested lifting beams

14

5) MAINTENANCE

Effective maintenance must aim at preventing :­ a). a reduction in the movement of water circulation through the boiler

- this can result in the formation of sediment or limescale on the
boiler immersion heater elements
b). pockets of high temperature water across the boiler immersion heater
elements – resulting in their destruction by overheating
c). accumulation of sediment or limescale within the boiler, particularly on
or around the boiler immersion heater elements – overcoming these
developments by the introduction of fresh, clean water without any inhibitor
or de-scaling agent

Minimum maintenance periods

A). Monthly maintenance
i). Check operation of the automatic air vent
ii). Check operation of the water flow switch
iii). Check operation of the safety valve

B). Annual maintenance
i). Carry out the monthly checks
ii). Check all the electric control functions
iii). Check all pipework joints are water-tight
iv). Drain off small amount of boiler water content and check for condition

C). 3-yearly maintenance
i). Carry out the annual maintenance
ii). Isolate the boiler safely from all services
iii). Drain the boiler of water and open up for inspection
iv). Check for all maintenance requirements and remedy as necessary
v). Close and seal the boiler, fill with fresh clear water through drain outlet
vi). Pressure test, then repeat annual maintenance procedure
