Information on the control panel
Identification number plate on the control panel
The maximum acceptable current is Icw = 23 kA.
Only authorised person should have acccess to the contrl panel
4.5.Connection to earth is compulsory. (Class 1)
After commissioning (8 days) :
A/ Check the immersions heaters tightness
B/ Check the power circuit connections tightness
For information, advised tightness of the bolts:
Check the tightness annually.
Regulation
Isolation of the power circuit
7. The boiler and the control panel should not been installe din a corrosive atmosphere or outside.
8. Ventilation (Natural convection or fan)
Leave enough space to allow air circulation. . Do not obstruct the fan and the grid.

INSTALLATION
The “multi-elec” electric boiler should be installed in a louvered plantroom in order to
ensure an ambient temperature below 30ºC and relative humidity between 30 and 80%.
The boiler should not be used in a corrosive atmosphere or in an external position.
Adequate access should be left around the boiler in order to carry out maintenance.
The following safety devices are obligatory:
Safety valve (4 Bars maximum)
An automatic air vent on the boiler flow
A blow down valve
Electrical wiring
The“multi-elec” electric boiler should be connected to 415V without neutral
The circuit breaker and the cables section should be chosen according to British
standards.
Class 1 material IP21 / IK08
If the boiler is powered without any water, it will generate the thermocouple failure (no
warrantee)
Transport and storage
The unit should be transported and stored in the original package until it reached the
installation point.
Ambiant temperature below 80ºC
Relative humidity between 30 and 80%

STARTING THE BOILER
Remove the power fuses
Check that the boiler is filled with water
Check that the immersion heaters are sound. If isolation is below 2MΏ, please
find the reason and remdy it.
Turn the power on using the main switch and the key switch
Check that the circulation pump is running.
Check that there is a lockout if the circulations pump stops
Adjust the temperature settings
Stop the boiler using the main switch
Put the power fuse in
Switch the boiler back on
Check the immersion heaters electrically for faults. Tight all the connections up
after one week of operation
If the boiler is powered without any water, it will cause the immersion heaters or
sensors to fail (no warranty)

SERVICING
Loss of water velocity through the boiler can lead to temperature rise
Consider a sediment vessel on the return to capture sediment deposit
Blocking immersion heaters irrigation can destroy them
NOTE : The immersion heaters can be destroyed by blockage of the water flow
It is essential that a periodical cleaning is carried out on the main heat exchanger and the
sensors. The water also needs to be clean without any antifreeze or scale remover product
Removal of sludge and sediment reduce corrosion risks
On first start:
Check the electrical operation
Check each terminal to avoid any contact resistance or temperature rise
Activate the safety valve manually
Monthly servicing
Check
The automatic air vent
The safety valve
Biannual servicing
Check each terminal to avoid any contact resistance or temperature rise

THE COMMISSIONING OF THE ATLANTIC MULTI ELEC
All Atlantic boilers and water heaters are thoroughly tested for mechanical, electrical and
combustion performance at the factory
The prime object of the site commissioning of the boiler(s) is, subject to installed
conditions, to match the optimum combustion performance results reached at the factory
and to ensure the boiler(s) is/are installed according to the conditions of guarantee.
The following check list should be satisfied before the commissioning takes place. To
arrange the commissioning Atlantic should be given a minimum of ten days notice of the
date and time required.
Commissioning sheet

THE GUARANTEE ON THE ATLANTIC MULTI ELEC
This guarantee is to the purchaser of the boiler(s) who is deemed to be the installer. If the
boiler(s) is (are) purchased by the eventual user who then arranges to install the boiler(s),
the eventual user is deemed to be the installer. The details of the guarantee are given to
assist the installer in obtaining effective action within the guarantee and they are in
addition to the installer’s legal rights under the relevant statutory enactments for the time
being in force in England, Wales, and Scotland.
Electrical equipment:
The replacement or repair of the item, including the cost of its delivery to the site of the
installation or its equal within England, Wales and Scotland, provided that the defect or
flaw occurs within 1 calendar year of the commissioning date.
Removable component of the boiler assembly (other than the electrical equipment)
The replacement or repair of the item, including the cost of its delivery to the site of the
installation or its equal within England Wales and Scotland if the defect or flaw occurs
within 1 calendar year of the commissioning date.
The main body of the boiler.
The repair of any welding defects in the main body of the water heater including any
necessary removal or replacement of that part of the water heater on site if the defect
occurs within 3 calendar years of the commissioning date.
Definitions:
The effective actions stipulated in this guarantee are subject to the purchaser complying
completely with the following:
1) The boilers are installed according to the recommendations of this technical
booklet, the recommended codes of practice of the C.I.B.S.E and the B.S.I., and
the checklist on page 13 is satisfied.
2) The commissioning of the boilers by ACM Atlantic and their regular annual
servicing and maintenance.
3) The payment in full, by the purchaser unless otherwise agreed, of the invoice for
the supply and delivery of the boiler(s) to site, any other relevant invoices
connected with the boiler positioning and fixing, and the invoices for
commissioning and any correction of installation error, all to be made within one
calendar month of the date of the invoice.
4) The presentation, at the time of a claim under the guarantee, of the boiler
registration number, the commissioning record with date, and the necessary
information for defining any replacement part.
5) When a replacement item is supplied for a defective item, the defective item must
be returned to ACM Atlantic at their registered office within 6 weeks of the date
of notification of the defect carefully labeled with registration number of the
boiler and the name and the order reference of the purchaser of the boiler. If this
is not complied with, the purchaser will be charged with the cost of the item and
its delivery.
