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 supported and 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 air cooler.
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 neutral with 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 neutral system.
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.
MAINTENANCE / RECYCLING
The device must be checked and inspected into service, regularly, by a qualified and approved personal, following rules.
The device will be subject to preventive maintenance (EN 378) :
-
external visual inspection of device,
-
checks of device during running,
-
checks of device corrosion.
Before working on pressurized composents, shut down the facility and wait until the equipment is at the ambient (room)
temperature.
Before removing the guards and panelling, turn off the device. Set it aside and make sure that no power is present.
Do not use piping to access on the equipment or to store something on the equipment.
The replacement of a safety valve must be made by the same brand of the original one.
If there is modification of type and /or brand, then the professional in charge of the replacement will do a calculation sheet
following EN 13136 and /or ask Profroid some elements.
Handle regularly the device valves in view to avoid theirs blocking on.
If a personal in charge of maintenance closed a blocked valve, this personal will must avoid the possible increase of pressure in the
part of device which is isolated.
