3 steps
Planned maintenance is the best way to avoid unnecessary expense and inconvenience. This procedure will help you check your system, have it inspected at regular intervals by a qualified service technician. The required frequency of inspections depends upon the total operating time and the indoor and outdoor environmental conditions.
  • Installation and maintenance must be performed only by qualified personnel who are experienced with this type of equipment and familiar with local codes and regulations.

  • Servicing Control Panel Components

  • Disconnect all electric power to the unit when servicing control panel components. Before servicing, always inspect units for multiple disconnects to ensure all power is removed from the control panel and its components.

  • Planned Maintenance

  • Preventive maintenance is the best way to avoid unnecessary expense and inconvenience. Have this system inspected at regular intervals by a qualified service technician. The required frequency of inspections depends upon the total operating time and the indoor and outdoor environmental conditions.

  • Routine maintenance should cover the following items:

  • Unit Storage

  • Location

  • The Daikin Rooftop Packaged System Unit is an outdoor unit. However, the schedule may dictate storage either on the ground or in its final position at the site.

  • If the unit is stored on the ground, additional precautions should be taken as follows:

  • Winterizing Water Coils

  • Coil freeze-up can be caused by such things as air stratification and failure of outdoor dampers and/or preheat coils. Routine draining of water cooling coils for winter shutdown cannot be depended upon as insurance against freeze-up. Severe coil damage may result.

  • It is recommended that all coils be drained as thoroughly as possible and then treated in the following manner.
