Why is my brand new HRV filled with water?
We did a DER in MA recently (complete September 2015). Part of the mechanical system design includes a Zehnder 350 that is designed to run 24/7 on medium flow to have sufficient air exchange. We have really high heat right now and high humidity. I noticed just now that it was making a strange noise. I opened up the cabinet (following the instruction provided) and found the right side (leads to the house air handlers) was full of water. There is a condensate outlet drain on the left but there is no way for water to get from the right to the left. I got in there with a shop vac and thoroughly cleaned out the water and dust. Turned it back on and it was fine.
It appears that the Contractor installed per the instructions (drain is supposed to the be on the left) but I suspect something is amiss with the installation. I reached out to the contractor to look at it and possibly fix whatever is wrong but I am hoping someone can offer an opinion or some thoughtful questions to ask or investigate to make sure this doesn’t happen again. Can you help us?
