Condensate Drain Pump Installation

Install pvc pipe from the drain back to near the furnace.

Condensate drain pump installation. Figure 3 connection of a condensate pump typical method nb manufacturer s detailed instructions should be followed. Riley archer is the product manager for aspen pumps at rectorseal corp. Mini split condensate pump selection and installation is critical for providing indoor air comfort and avoiding property damage from evaporator drain pan overflows. Before installing the pump let the air conditioner run a few cycles so that some condensate collects and to remove any oils that are left in the system.

Anchor the pipe to the ceiling or wall depending on how it is run. Ensure all pvc joints are cleaned and glued properly so they do not leak. For the primary condensate drain the installer piped 3 4 pvc into a condensate pump which will discharge into a nearby vanity sink prior to the trap via 3 8 vinyl plastic tubing. Key 1 condensate discharge from boiler 2 condensate pump 3 visible air break at plug hole.

Once the condensate reaches a specific level the condensate pump is turned on by the built in float switch. So furnace installers mount a condensate pump right on the furnace and route the drain line to a far off sink or floor drain. Stop the pvc pipe above the furnace for now until the condensate pump is installed. Condensate switches imc 307 2 3 states that all hvac equipment that produces condensate must have either a secondary drain line or a condensate overflow switch a secondary drain pan with a secondary drain line or condensate switch or some combination of these installations should be used to prevent overflow if the primary drain line blocks.

For the secondary drain system he installed a wet switch within the pan below the unit which will turn the unit off upon water detection. The problem could be just algae buildup in the pump s check valve. The float switch and the reservoir make up a condensate pump. Locate the drain where the condensate will be sent.

The reservoir is connected to the drain pan where it collects water while your mini split unit cools. Note any external pipe work should be insulated pipe cut at 45 degrees and a drain leaf guard fitted.
