Safety - Toshiba QuietCo2OL Notice D'instructions

Reminder
Carbon dioxide is a colorless and odorless gas, whose presence in excess in the atmosphere can lead to discomfort, such as
headaches, difficulty concentrating, even with low levels of concentration and nausea in the case of greater than 1000 ppm.
Carbon dioxide gas is heavier than air and is located at lowest point of spaces when they aren't
ventilated. Machinery room must be equipped with a carbon dioxide detector as required by EN 378.
In case of carbon dioxide evacuation (vacuum draw, etc ...), it is important to have a connection through safety valves discharge
pipes as required by EN 378.
As professional, the installer must :
· define the operating conditions of the refrigeration equipment under his own responsibility regarding the design. This device needs
to be incorporated in machines conforming to the Machines Directive. Its commissioning is only authorized if it has been
incorporated in machines which fully satisfy the legal regulations.
· complete and adapt these recommendations, if necessary, by adding other safeties and /or controls according to the
refrigeration equipment's operating conditions.
· have performed all the installing, commissioning and maintenance operations by qualified professionals and conforming with
standards EN 378, EN 14276, EN 13136, EN 13313, EN 60204 and EN 60335, the EU directives, the safety rules generally
recognized, sound engineering practice, the local regulations ; as well as those which may be set up, taking into account the
evolution of the technology and the regulations.
If the installation, the commissioning, the operating, the maintenance are not realised according to this operating instructions,
the responsibility of the manufacturer cannot be involved.
· completely inform the customer on the control, maintenance and follow-up of the refrigeration equipment.
The devices are delivered under pressurized nitrogen or dry air (make sure at reception that material is under pressure by
using a pressure gauge) ; except dry cooler, brine air cooler.
Respect the standard for transport and handling of pressure devices.
Install device in a space with sufficient ventilation regarding standards and regulations because device is under pressure of nitrogen
; except dry cooler, brine air cooler.
Very important : before performing any servicing operation on refrigeration equipment, the electric power supply must be
turned off. The contractor or the company in charge of the installation shall be responsible for carrying out the required
instructions.
The manufacturer disclaims any responsibility for change(s) or repair(s) on its devices made without its
prior agreement. The devices are exclusively intended for professionals, for refrigeration purposes and for
their limits of use.
The identification of device and his range of use are written on the name plate. The name plate is stuck on device. Name plates are
located : on the coil for heat exchangers, on the frame for racks, on the housing for condensing units, on the receiver for liquid receiver
sets and for liquid sub-assembly. The name plate is joined to this operating instructions (.pdf). The complete installation must be
designed and used not to exceed the range of use. Device is designed for a maximum ambient temperature of 38°C (as standard
configuration).
The user or operator shall ensure the control and maintenance of the equipment with qualified professional complying with the
instructions below, possibly completed by the installer. For these operations, the standards and directives mentioned above remain usefull.
This is also available during the stop of the refrigeration installation.
The average life cycle for the design of our devices is of a minimum of 10 years, provided if you follow our operating
instructions. The manufacturer cannot be held responsible in case of violation to the recommendations of them.
Equipment piping are made with different types :
0
in copper, standard NF EN 12735 and K65
0
in stainless steel, standard NF EN 10217-7 (type 304L – X2CrNi18-9 ; n° 1.4307)
These pipings must be inspected regularly following standards, sound engineering practice and local regulations in the country of use.
Some heat transfer fluids can be harmful or corrosive, and their uses must be realised in relation with their risks, if there is a
leak on pipings.
