General Warnings; Danger Of Burns; Warnings - Carel Heosbox Mode D'emploi

1.1 General warnings

document is the set of original instructions originally written in
This
English; all other languages have been professionally translated. For
the intended meaning reference must always be made to the original
English version. The Heosbox units are water-cooled condensing units
for indoor use in medium and low temperature commercial refrigeration
applications. Heosbox is a partly-completed machine and as such must
be appropriately connected to an evaporating system in order to function
correctly. Heosbox and the evaporating unit together comprise the
complete equipment. Carefully read this booklet and all documentation
supplied with the unit. This documentation must be kept by the customer
(manufacturer, designer, installer or owner of the final equipment) for any
future maintenance or service. The warranty will be void if the instructions
described under "Warnings" are not complied with. The operation of
Heosbox is specified in the technical documentation supplied with the
product or can be downloaded, even prior to purchase, from the website
www.carel.com. Every product supplied by CAREL Industries, in relation to its
advanced level of technology, requires setup/configuration/programming
to be able to operate in the best possible way for the specific application.
Failure to complete such operations, which are required/indicated in the
user manual, may cause the final product to malfunction; CAREL Industries
accepts no liability in such cases. The customer (manufacturer, developer,
installer or owner of the final equipment) accepts all liability and risk
relating to the configuration of the product in order to reach the expected
results in relation to the specific final installation and/or equipment. CAREL
Industries may, based on specific agreements, act as a consultant for the
installation/commissioning/use of the unit, however in no case does it
accept liability for the correct operation of the unit and the overall system
if the warnings or suggestions provided in this manual or in other product
technical documents are not heeded. In particular, as well as observing
the above warnings and suggestions, the following warnings must be
observed for correct use of the product:
DANGER OF ELECTRIC SHOCK: the unit contains live electrical
•
components. Disconnect the mains power supply before accessing
inside parts or during maintenance and installation. It is forbidden to
remove the access panels to the internal parts of the unit without first
having placed disconnect switch QS1 and the switch or disconnect
device on the Heosbox power supply line in the OFF position (see
the wiring diagram). The mains power disconnect device must have
a contact opening distance that allows complete disconnection in
overvoltage category III conditions; it must also be incorporated into
the Heosbox power supply line in accordance with national regulations.
• DANGER OF WATER LEAKS: the unit comprises components
containing water or water with antifreeze additive (generally glycol).
Malfunctions in the unit's connections or to its operation may cause
fluid leakages. Avoid direct contact of the fluid with the eyes/skin and,
in the event of accidental contact or inhalation, seek medical advice.
• DANGER, PRESSURE EQUIPMENT: the unit is supplied sealed
with an inert gas (nitrogen) pre-charge of around 1 bar (14.5 psi) above
atmospheric pressure. Take all necessary precautions to avoid material from
being expelled outside of the unit when venting the gas. Before charging
the unit with R448A or R449A refrigerant, make sure that all the operations
described in "Introduction", "Handling" and "Installation" have been carried
out. After connecting the Heosbox to the evaporator system, the PS and TS
values shown on the label on the machine and reported in this manual must
be considered, based on the refrigerant used. Always wear protective glasses
when performing any work on the unit.
• DANGER OF BURNS: the unit contains components that may
reach high temperatures. Take all necessary protective measures before
performing any operations on the unit.

installation (upside down or on one side), wait at least 24 hours before
starting it the first time.
• Heosbox is specifically designed to be connected to evaporator coils
with air as the secondary fluid, placed inside a refrigerated showcase or
cold room. Connection to other types of evaporators may compromise
safety, cause malfunctions and affect the performance of the unit;
CAREL Industries declines all liability for damage consequent to or
caused directly by connection to such evaporators.
