Common Questions

How often should the evaporator pad be replaced in the P110-SBP2412?
For peak HVAC performance, technicians recommend replacing the aluminum evaporator pad at least once per heating season. In areas with high mineral content in the water, a mid-season check is advised to prevent scale buildup.

Can this unit be installed on the return duct?
Yes, the Carrier P110-SBP2412 is designed for flexible mounting on either the supply or return plenum. Proper bypass ducting must be installed to connect to the opposite side to create the necessary pressure differential.

Does this unit require a floor drain?
Yes, as a drain-through humidifier, it is designed to flush away built-up minerals. A 1/2-inch ID drain hose must be routed to a nearby floor drain or condensate pump.
