Operating - Carrier QUIETCO2OL Handbuch

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 lifting operations.
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 necessary rules.

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 neighbourhood 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 unfavourable 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
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.
