Ariston NUOS PLUS 200 Instructions For Installation, Use, Maintenance page 21

Instructions and technical norms
The purchaser pays for the appliance's installation, which must be
carried out by qualified personnel only, in conformity with national
regulations in force and any provisions emitted by local author-
ities or bodies responsible for public health, and in accordance
with the specific manufacturer indications contained in this manu-
al. The manufacturer is responsible for the product's conformity to
the relevant construction directives, laws and regulations in force
at the time the product is first commercialised. The designer, in-
staller and user are each exclusively responsible, in their respec-
tive fields, for knowing and observing the legal requirements and
technical regulations concerning the design, installation, opera-
tion and maintenance of the appliance.
Any reference to laws, regulations or technical specifications
contained in this manual is purely for information purposes; any
new laws introduced or modifications to existing laws are not in
any way binding on the manufacturer towards third parties. It is
necessary to ensure that the power supply network to which the
product is connected complies with the EN 50160 norm (under
penalty of warranty invalidation). Relative to France, ensure that
installation complies with the NFC 15- 100 norm. The tampering
of product integral parts and/or supplied accessories invalidates
the warranty.
Field of application
This appliance is intended for hot water production for domestic
use or similar, at temperatures below boiling point.
The appliance must be hydraulically connected to a domestic wa-
ter supply line and to a power supply network.
Exhaust ducts may be used for the entry and discharge of pro-
cessed air.
It is forbidden to use of the appliance for uses other than those
specified. Any alternative use of the appliance constitutes im-
proper use and is prohibited; in particular, the appliance may
not be used in industrial cycles and/or installed in environments
exposed to corrosive or explosive materials. The manufacturer
shall not be held liable for any damage due to faulty installation,
improper use or uses deriving from behaviour that is are not rea-
sonably predictable, and incomplete or careless implementation
of the instructions contained in this manual.
Operating principle
The efficiency of a heat pump cycle is measured by the Coef-
ficient of Performance (COP), i.e. the ratio between the energy
supplied to the appliance (in this case, the heat transferred to the
water to be heated) and the electrical energy used (by the com-
pressor and the appliance's auxiliary devices). The COP varies
according to the type of heat pump and to its relative conditions
of operation.
For example, a COP value equal to 3 indicates that for every 1
kWh of electrical energy used, the heat pump supplies 3 kWh of
heat to the medium to be heated, of which 2 kWh are extracted
from the free source.
Packaging and supplied accessories
The appliance is anchored to a wooden pallet and is protected with
polystyrene top cover, wooden edge protectors, and external card-
board; all the materials are recyclable and eco-compatible.
The following accessories are included:
- Connection pipe for condensation water;
- 2 ¾" dielectrics coupling and joint;
- Instruction manual and warranty documents;
- Energy label and product fiche;;
- 2 adapters for Ø150 and Ø160 ducts.
Product certifications
The CE marking of the appliances attests its conformity to the fol-
lowing EC Directives, of which it satisfies the essential requisites:
