  • Page 6: Pre-Installation

    Pre-installation Pre-Installation Movement and Storage The unit must not be transported, moved or stored at greater than a 30° angle from the upright position. Store the unit in a dry area until required. The unit must be installed by a suitably qualified tradesperson and all electrical wiring must be completed by a licensed electrical contractor in accordance with all local Standards.
  • Page 7 Pre-Installation Do not un-weld or flame cut the refrigerant lines including any refrigerant circuit components until the entire refrigerant (liquid and vapour) has been removed from unit. Traces of vapour should be displaced with dry nitrogen. Refrigerant in contact with an open flame will produces toxic gases. Ensure that the necessary safety protection equipment is available when servicing.

  • Page 57: Maintenance

    Maintenance Maintenance To ensure the optimal performance of the unit regular maintenance is essential. Failure to undertake regular maintenance can reduce the unit performance and of the system shorten the life of the unit . Exterior Maintenance 1. Make regular checks throughout the year that the inlet grill is not blocked or clogged by leaves, snow or anything else.
  • Page 58 Maintenance If there is not enough refrigerant in the system, this is indicated by gas bubbles in the moisture sight glass .the unit will have poor performance. If the low refrigerant charge is significant, large bubbles appear in the moisture sight glass and the suction pressure drops, then the compressor suction superheat will also be high.
  • Page 59 Maintenance Mechanical Maintenance 1. Check the tension of the fan motor, fan wheel, compressor and control box fixing bolts. 2. Check that no water has penetrated into the control box. Evaporator Coil It is recommended that the finned coils are inspected regularly to check the degree of fouling.
