  • Page 12: Health & Safety

    Health and Safety Important Note: Only qualified personnel, who are familiar with refrigeration systems and components including all controls, should perform the installation and start-up of the system. To avoid potential injury, use care when working around coil surfaces or sharp edges of metal cabinets. All piping and electrical wiring should be installed in accordance with all applicable standards and local by-laws.

  • Page 13: Installation

    Installation Unit location In order to achieve maximum cooling capacity, the installation location for the condensing unit should be carefully selected. • Install the condensing unit in such a way so that hot air ejected by the condensing unit cannot be drawn in again (short circuit •...
  • Page 14 Installation Field piping Important Note: Pipe sizing should only be determined by qualified personnel. Correct line sizing will minimize the pressure drop and maintain sufficient gas velocity for proper oil return. All applicable standards must be observed in the installation of refrigerant piping. To ensure satisfactory operation and performance, the following points should be noted: Pipework routes must be as simple and as short as possible.
  • Page 15 Installation Pressure testing The condensing units are pressure tested in the factory prior to dispatch. All units come with a holding charge of oxygen free nitrogen. Remove the holding charge indication tag which is tied to service valve before installation. Once the pipework installation is complete, it should be pressure tested prior to evacuation to test for leaks.
  • Page 16 Installation Electrical Important Note: The mains electrical supply to the condensing unit must be via a suitable motor rated circuit breaker or fuse. A mains isolator is fitted to all condensing units therefore an additional isolator is not required unless site conditions or regulations dictate differently.

  • Page 24 Commissioning Compressor Operation The compressor(s) operate in accordance to the suction pressure setpoint which is programmed into the controller. There is a differential pressure setting both above and below the setpoint. This allows stable operation of the compressors without constantly switching on & off due to small variations in suction pressure. This range is known as the Neutral Zone.
