Condensate Drain Pump Installation

Stop the pvc pipe above the furnace for now until the condensate pump is installed.

Condensate drain pump installation.

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. 2 make sure that all of the packaging is removed from the pump and that all venting slots are clear from debris. 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.

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. 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. Once the condensate reaches a specific level the condensate pump is turned on by the built in float switch. 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. If that condenser pump fails the water overflows the pump and spills onto the floor. The float switch and the reservoir make up a condensate pump. 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.

Locate the drain where the condensate will be sent. Figure 3 connection of a condensate pump typical method nb manufacturer s detailed instructions should be followed. Anchor the pipe to the ceiling or wall depending on how it is run. Install pvc pipe from the drain back to near the furnace.
