Drain Pan For Horizontal Ac In Attic. Imc 307 2 5 states that the condensate assembly must be installed in such a way that the drain line can be cleared of blockages and maintained without cutting the drain. Emptying standing water from the drain pan on a regular basis will help prevent the growth of algae which is one of the major causes of clogs in ac drains. The ac drain pain was leaking underneath the air handler unit on my central ac and water leaked out from my bathroom wall socket.
If the outlet is on the opposite side of the pan water will pool before draining. Locate under hvac unit and attach to 3 4 in.
Because entire central air system is lying on its side in the event of condensate drain pan failure water does not drip in one general location.
When a drain line is pvc the imc dictates that it should be supported every 4 when horizontal while maintaining proper pitch and every 10 vertically. Drain pans collect condensation to prevent leakage in walls and ceilings due to moisture run off from primary ac pans. The important part of this attic installation is that the air handler has plenty of drains and a safety cutoff to ensure that the air handler turns off before the secondary drain pan overflows into the attic. Drip pans also called condensate pans are placed under the air conditioner coils to catch any condensation that forms.
