Condensate drain pump installation.

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. The reservoir is connected to the drain pan where it collects water while your mini split unit cools. So furnace installers mount a condensate pump right on the furnace and route the drain line to a far off sink or floor drain. 2 make sure that all of the packaging is removed from the pump and that all venting slots are clear from debris.

Anchor the pipe to the ceiling or wall depending on how it is run. Once the condensate reaches a specific level the condensate pump is turned on by the built in float switch. That doesn t necessarily mean the pump is bad. 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.

Install pvc pipe from the drain back to near the furnace. The problem could be just algae buildup in the pump s check valve. Ensure all pvc joints are cleaned and glued properly so they do not leak. 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. Riley archer is the product manager for aspen pumps at rectorseal corp. Locate the drain where the condensate will be sent.

Note any external pipe work should be insulated pipe cut at 45 degrees and a drain leaf guard fitted. Mini split condensate pump selection and installation is critical for providing indoor air comfort and avoiding property damage from evaporator drain pan overflows.
