  • Page 23: Installation

    INSTALLATION PLANT HANDLING The equipment travels and is unloaded at the risk and peril of the recipient, who must ensure, on receipt and after unloading, that the equipment is in good condition, checking in particular that the control unit has not been damaged during transport or unloading, or during its final installation, and that no parts are missing (dampers, dehydrator cartridges).

  • Page 24: Layout Recommendations

    SITING RECOMMENDATIONS Note: Air-cooled units are intended for outdoor installation. 3.2.1 General The unit must be installed and secured on a level surface capable of supporting the weight of the unit (4 fixing points provided). Any other mounting must be the subject of a structural study adapted to the unit's chassis. The unit must be perfectly level, so as not to create an accumulation of oil at low points in the suction and discharge piping, or cause vibrations.

    CONNECTION TO THE REFRIGERATION NETWORK Important: This operation must be carried out by competent personnel trained in refrigeration machinery. Caution: due to the presence of electronic equipment in the machine's electrical cabinet, no electrical welding operation should be undertaken while the machine is powered up, otherwise electronic components may be destroyed. 3.3.1 Piping networks: Before any work is carried out on the refrigerant circuit, the standby charge must be evacuated.

  • Page 28: Hydraulic Connections

    Caution: Measures must be taken during tests at 1.1 x PS, which are carried out on site under the installer's responsibility, to prevent the safety valves from being stressed (dismantling). This test must last at least 30 minutes. 3.3.2 Hydraulic connections The hydraulic circuit of the units is made of copper.

  • Page 29: Electrical Equipment

    ELECTRICAL EQUIPMENT 4.1 GENERAL The refrigeration unit is fitted with an electrical board designed solely to control the machine's compressor(s) and auxiliaries. It is designed in compliance with EN 60204-1. All on-site wiring must comply with the legal standards in force in the country of installation (NF-C 15-100 in France) and with EN 60204-1.

  • Page 30: Recommendations

    5.2 RECOMMENDATIONS To ensure proper operation of the system, we recommend the use of the Procold control box, comprising a cold room regulator, an electric expansion valve driver and a Carel stepper valve.

    This oil (PAG type) is fully miscible; If you wish to use another type of oil, please contact PROFROID or the compressor manufacturer. However, we would like to remind you that oil return does not depend solely on the type of oil, but also on the configuration of the refrigeration circuit (slope, rise, siphon and counter-siphon) and circulation speeds, particularly at suction, which should be higher than 4m/s horizontally and 7m/s vertically.
  • Page 39 Close the vacuum pump and inject R744 vapor until a pressure of 7-10 bar is reached, to prevent the formation of dry ice. Dry ice can damage circuits and make charging impossible. Charge the vapor in the suction and liquid lines. Check that the expansion valve on the evaporator(s) is open.

  • Page 40: Compressor Start-Up

    COMPRESSOR START-UP LOAD SUPPLEMENT Very quickly, top-up the charge. A low fluid charge leads to high overheating, and therefore to abnormally high discharge temperatures. A charging connection is located at the dehydrator station. 6.4 FEATURES OF THE WATER COOLING UNIT On water-cooled units, the cooling fluid must be water or a mixture of water-MEG or water-MPG (maximum MEG/MPG concentration 60%).

  • Page 41: Operations

    OPERATIONS The refrigeration unit is a PES under the PED and is integrated into a functional unit which must itself meet the essential requirements of the PED. The design of the refrigeration unit complies with this requirement by applying EN 378 standards 1 to 4, by provisions on the equipment and by the recommendations in this manual.
