Safety Rules - Onda EKC Manuel D'emploi

ASSEMBLY INSTRUCTIONS / INSTALLATION
ONDA Heat Exchangers are designed to be used in industrial
and commercial cooling system in facilities where there
aren't any hazardous substances.
The electrical installation shall comply with machinery
safety rules. The electrical equipment of the machine shall
comply with IEC 60204-1. Qualified companies operating
in the electro-technical and refrigeration field regulate and
control heat exchangers inside refrigeration systems.
ONDA heat exchangers are designed carefully in order to
be used between a minimum and a maximum operating
temperature and under a maximum pressure (PT) indicated
on the nameplate of each heat exchanger. Those limit
values shall not be exceed.
Noise limit values indicated on the product documents are
measured in free-field conditions. The noise values may
deviate considerably from the ones indicated on the product
document depending on the structure heat exchangers
are installed in and on the materials heat exchangers are
produced with.
It is necessary to inform the supplier if supplied products
are defective. The supplier shall be granted the possibility
to repair or correct the defect. Expensesn due to third-party
services are accepted only if they are previously authorized
by the supplier.

SAFETY RULES

Watch out: read carefully following rules!
It is extremely important to respect safety and the
environment!
Heat exchangers are semi-finished products designed to
be working by means of refrigerant fluids or refrigerating
media. These substances circulate under pressure. They
can be inflammable and/or corrosive. For this reason, it
is necessary to adopt the precautionary principle and to
follow safety rules. If media - which might possibly freeze -
are used, it is necessary to make the necessary decisions in
order to prevent damage to the heat echanger.
If the room temperature rises, the pressure might increase
and exceed the maximum value possible. The heat
exchanger filling factor must not exceed 80% since a full
fluid filling may cause irreparable damage.
Our heat exchangers may only be used for the purpose
intended and with the substances they are designed for.
Substances are indicated on the nameplate. Inappropriate
use and other forms of improper use with substances
different from the ones indicated without the supplier
authorization may result in the loss of warranty.
As manufacturers, we are not always aware of the effective
use of our heat exchangers, since supplied heat exchangers
are supplied as semi-finished products. For this reason, the
final user is always responsible.
