USER MANUAL Water heater
1. General
This document is intended for the installer and final user.
Therefore, after plant installation and start-up, ensure that this
document has been delivered to the final user or managing
supervisor of the plant.
Atlantic water heaters have been designed and constructed for the
production and storage of sanitary hot water by means of a heat
exchanger obtained with the help of extractable, fixed or external
exchangers on the Water heater, powered by sources of thermal
energy of various types (Heat generator, Heat Pump, Solar panel)
which use water as a thermal carrier liquid.
Any use of this product which is not in accordance with information
indicated in this document shall release the manufacturer from all
liability and will void all aspects of the guarantee.
Products described in this document have been constructed in
compliance with directive 97/23/CE (PED) relative to pressure
equipment with contained liquid and according to operating
conditions provided for use.
1.1 Category identification (Specification EN 12897:2006 -
Directive 97/23/CE)
The PECS Water heaters has been designed in accordance with
specification EN 12897:2006 and have been tested according to
provisions of this standard.
The entire range of Atlantic Water heaters have lower levels than
the threshold values described as follows:
• Receptacle for water containment (group 2) with a vapour
pressure at maximum permitted temperature less than 0.5 bar
over normal atmospheric pressure (1033 mbar), maximum
operating pressure PS > 10 bar, product PSxV > 10,000 [bar x L],
PS > 1000 bar;
•Piping for water containment (group 2) with vapour pressure at
maximum permitted temperature less 0.5 bar over normal
atmospheric pressure (1033 mbar), maximum operating pressure
PS > 10 bar, diameter DN > 200 and product PS x DN < 5000 [bar
xmm].
Therefore, all Atlantic Water heaters, in accordance with Art.3.3.
and as shown in attached tables 4 and 5, must not be CE marked.
However, Atlantic S.r.l. guarantees standard manufacturing
procedure as established by the directive (according to Quality
management and quality assurance standards UNI EN ISO
9001:2000 – UNI EN 14001:2004) which ensures user safety and
manufacturer identification.
For Heat exchanger used in solar thermal systems (or another
type of plant) with temperature > 110° C in the pri mary circuit, it is
recommended to dimension the system so that:
−
The primary circuit temperature does not exceed the temperature
of 140° C (to be reached only for limited periods o f time).
−
The max working pressure meets the following limitation:
the product: Pressure exchanger x Volume must not exceed 50
bar
·
litre according the formula:
P • V
≤
50 [bar • l]
So, given the volume of fluid in the heat exchanger, it’s possible to
calculate, with the above formula, the maximum admissible
pressure for each heat exchanger.
Beyond these limits the heat exchanger (as well as the plant) is
subject to the requirements for pressure equipment (design,
checks at the plant and in operation, periodic retraining etc) and
therefore heat exchangers designed and tested according to
regulation 97/23/EC PED are required.
2. Installation and maintenance
Water heaters must always be installed sheltered from
atmospheric agents, on adequately solid bases and, before any
connections are made, making sure that there is sufficient space
for exchanger, magnesium anode and resistance extraction.
• If in some periods of the year, the places where are installed the
water heater or the pipelines are subject to temperatures < 0°C, It
is necessary to provide for adequate protection against frost, such
as, for example, the control of temperature with a thermostat in the
premises or programmed reheat cycles of the heating generator or
auxiliary resistance (not supplied).
• With regard to the 150 to 500 litre capacity versions, for a correct
levelling of the tank you need to use the provided adjustable feet
with the rosettes (OPTIONAL), making sure you fasten the locknut
(see detail in diagrams). To avoid breaking the insulation, lift the
tank from the ground using spacers on all three feet.
• Verify that the position where Water heaters are to open are
large enough to allow for free passage toward the outside without
any need for demolition. The guarantee does not cover any costs
derived from a failure to observe this point.
• Ensure that the position where the Water heater is to be installed
is equipped with a draining (outlet) system suitable for the tank
and any other equipment volume. The guarantee does not cover
any costs derived from failure to observe this point.

• Handling phases requiring movement of equipment with weight
exceeding 30 kg and require the use of proper hoisting and
transport means. For this purpose, receptacles are to be moved
only when empty by means of special platforms or hoisting
eyebolts.
• Verify the presence of magnesium anodes upon installation and
check the electrical continuity with the tank (in particular for anode
without grounding wire).
