Magnum Series
DRAINAGE, CONTINUED
Internal Float Switch
The evaporator unit comes equipped with a oat switch to monitor the level of condensation in the internal drain pan. If
the drain line is obstructed for some reason, and the water level in the drain pan gets too high, the oat switch will stop
the unit from operating. In this event the control will send an alarm to the display. (The alarm message displayed will be
“EA.” The unit will not operate until the water in the internal drain pan drops back below the proper level.)
All joints and connections shall be made in accordance with the applicable provisions of Chapter 7 of the International
Plumbing Code relative to the material type. Condensate waste and drain line size shall be not less than ¾ inch (19 mm)
internal diameter and shall not decrease in size from the drain pan connection to the place of condensate disposal.
