I have a used Norlake Walk-in that is serviceable. When I first got it, I had an issue with the temperature fluctuating wildly - it would go as low as 20 degrees then up to 41. A repairman came out a couple times and said he adjusted the pressure to force the cooler above freezing regardless of the thermostat.
I now have 2 problems:
The walkin leaks water like crazy from the fan. I climbed on top and the pan that houses the water is full. The coil that (I guess) evaporates the water is very hot I just think it’s getting overwhelmed…
It hovers dangerously close to 40 degrees all the time.
Is the pressure something I can adjust myself? Any thoughts on why it’s dripping water?
One more question - my contractor installed the ceiling panel with the cutout closest to the wall (there are 5 ceiling panels so it could have gone in the middle. Further, the fans and the “diffusor” grate are pointed at the wall and not to the center of the cooler. Having never installed one of these before, I have no idea if this is proper or not. Nor-Lake does not have the install guide on their website…
I have mine installed exactly like you posted above and I greatly regret it. I have to get a contortionist to clean the coils on the thing, and heaven help us if it ever needs a repair. If the manufacturer says it’s OK, I would rearrange it so you have better access and airflow.
Thanks George. It’s an 8x10 walkin with a floor. The capsule pak is a 5/8th horsepower (115v). I had norlake send me the manual. I’m going to have my contractor come out and re-arrange the ceiling panels so the unit blows out to the middle. It has two fans that both point in the same direction. I climbed up and noticed a couple things:
The manual calls for a 15 minute defrost every 3 hours and mine was set for a 60 minute defrost every 6 hours.
The coil (I’m gonna plead ignorance here) that the fans blow on is (and has been) covered in a layer of ice. I’m assuming this is related to #1. How do I remove the ice? Hair dryer? Hot water?
Best to advance your timer and put unit into defrost cycle. It should do no harm to assist the defrost with a hair dryer. Once you clear the ice, set the defrost cycle to the factory specs and check frequently.
I think that is similiar to our defrost cycle. I know it goes on the long defrost at 3:00 am… something they just recently change.
I asked hubby about the pressure and he (who follows the techs around so we learn how to do repairs in the future) said changing the pressure is worth checking into by a professional (He said they have all the gauges and such) But he first asked if you have cleaned your condenser? After reading your recent additions you may want to triple check they are clean. I know for us we have cotton trees and the condenser gets awful…quickly.
I would have a pro come do the pressure. For us it would be 120 bucks for the call and of course they look it all over. We found a great company in illnois/missouri. Been using them for years. We have not had a problem since.
