3.3 AUXILIARY OVERFLOW PAN
To comply with building codes, an auxiliary overflow pan must installed under all equip-
ment containing evaporator coils that are located in any area of a structure where dam-
age to the building or building contents may occur as a result of an overflow of the coil
drainpan or a stoppage in the primary condensate drain piping. Aftermarket overflow
pans are available or one can be fabricated in the field as required.
3.4 DRAIN PAN OVERFLOW SWITCH
An overflow switch is available as a factory option (option code 417) or a field installed
accessory kit (RXHK-A01- See Section 6.2) that will shut the outdoor unit off to prevent
the water level in the unit drainpan from rising above a safe level. As with the auxiliary
overflow pan, most building codes require a drain overflow switch for installations where
structure damage can occur as a result of an overflow of the unit condensate drainpan.
3.5 CLEARANCES
• All units are designed for "0" inches clearance to combustible material on all cabinet
surfaces.
• Units with electric heat require a one inch clearance to combustible material for the
first three feet of supply plenum and ductwork.
• All units require 24 inches minimum access to the front of the unit for service.
• These units may be installed in either ventilated or non-ventilated spaces.
