Service Clearance

Location . Care should be taken for the installation
location to minimize snow drifts on the outdoor coil.
Allow service clearances as approximately indicated in
1. Also, Daikin recommends providing a roof walkway to the
rooftop unit as well as along each side of the unit that provides
access to most controls and serviceable components.
Refer to NEC and local for minimum clearances around the
unit and control panel.

Ventilation Clearance

Below are minimum ventilation clearance recommendations.
The system designer must consider each application and
provide adequate ventilation. If this is not done, the unit may
not perform properly.
Unit(s) Surrounded by a Screen or a Fence:
1 . The bottom of the screen or fence should be at least 1 ft.
(305 mm) above the roof surface.
2 . The distance between the unit and a screen or fence
