INSTALLATION
The loading and unloading operations must be performed with adequate handling equipment (forklift, crane, etc.) using possible lifting
points provided for this purpose.
The qualified professional should be certified and will wear individual safety equipment (protective gloves, glasses, safety shoes, etc.);
operators will never circulate under the load during liftingoperations.
During handling, the operator will ensure a good balance to prevent the equipment from swinging.
Make sure that the equipment or its accessories have not been damaged during shipping and no parts are missing.
If devices are used in a seismic area, then the installer must apply all necessaryrules.
If the appliance is installed in an area for which consideration of the external fire situation is mandatory, then the installer must make
the necessary arrangements.
Enough free space all around the refrigeration equipment should be provided to facilitate maintenance operations.
The heat exchangers must be installed in locations free of any external dust or other pollutants from the neighborhood which could
obstruct or clog the coils.
If devices are used in a corrosive area (sea side, pollutant gas, etc.), make sure that appropriate anticorrosion protection has been
provided.
Make sure that pipings are connected to the appropriate pressurized equipment (EN378-2).
All connecting pipings must be correctly supportedand clamped.
For the connection of pipings, protect sensitive components located around the permanent assemblies to be made.
Before any intervention, the operator must obstruct all the openings of the circuit (+ pressurization under nitrogen) ; except dry
cooler, brine aircooler.
Discharge pipings (outlets of safety valve for example) must be installed in view to protect people and apparatus from leakage of
refrigerant.
Make sure that flexible hoses are not in contact with metal parts.
The products added for thermal and /or acoustic insulation must be neutralwith respect to support materials.
The protection devices, pipings and accessories must be protected against unfavorable effects from the environment.
Make sure that access and emergency exit ways are not obstructed to comply with the local regulations.
COMMISSIONING
Prior to electrically connect the facility, make sure that the AC power line voltage and frequency ratings correspond to the indications
on the identification plate and the power voltage is within a tolerance of + 10 % with respect to the rated value.
Specific protection is provided according to the neutralsystem.
Any on-site wiring must comply with the legal standards in force in the country of installation (including grounding).
Before turning on a device, make sure that:
- the electric connections have been correctly made
- the clamping screws of the various terminals are correctly tightened
Check the possible presence of locking devices of compressor antivibration elements, and remove them, if they exist.
OPERATING
Do not use the refrigeration equipment or components for any utilization other than that for which it is designed.
Comply with the special manufacturers' recommendations contained in the manufacturers' operating instructions.
It is strictly prohibited while the device is running to remove the guards and panelling provided by the manufacturer to protect the
user and ensure his safety.
When operating, surface temperatures above 60°C and /or below 0°C may be reached. During any servicing operation, the personnel
should be extremely careful while working on the device.
Profroid is not informed to real use of partly completed machines; their integrations and use must comply to Machines Directive and
recommendations of this operating instructions.
Results of design calculations, checks, and test reports in relation with low voltage directive are archived.
Modifying the setting of the safety valves is absolutely prohibited.
When working on a sealed valve as part of a maintenance operation, it is mandatory to install a new seal immediately after this
operation, making sure beforehand that the valve is returned to its original position.
