TRUE M# TAC-48GS
I worked on a reach in cooler today and now I have a couple of questions for you refer guys. Is it normal to have a cooler that runs on 404a? I have seen plenty of freezers with this refrigerant, but I think this is the first cooler. This is a milk cooler. Trying to maintain 38-40*. My second question is What is the cardboard thing in the condensate pan? Is that supposed to wic the water up into condenser fan air stream? Also I noticed when I put unit into defrost the condenser fans reversed rotation. Why does it do this? I don't work on many reach ins but if I don't ask I'll never learn. Thanks for any input.
