Installing indoor unit outdoors
Someone told said customer that there isn't enough air above walk ins despite egg crates all over and plenty of condenser cooling blah blah not enough make up air blah blah- so they are dead set on moving to outdoors and the beloved salesman is all to happy to sell an outdoor new units. What would the repercussions be of using the same units and building an enclosure and installing a head master- units pump down and receiver "seems" - and I'm ducking behind the couch by saying seems- sized accordingly and using the same units outside? I'm sure it's been done

No problem, it's done all the time. Not necessarily correctly though. What's the winter ambient there ?

I see it all the time..it just needs an enclosure and some type of head pressure control and a crankcase heater on the compressor. Fan cycling is usually used but you have to be careful using that on a single fan condenser because the fan will usually provide additional cooling for the compressor..good luck.

Ah ha- very good question- northern mn. Easily see stretches for weeks below zero- ok in addition to head master we install a CCH to heat the receiver. Head master for sure as indicated originally I've been informed on this site that fan cycling is forbidden on Refrig especially with txvs

You'll be fine just make sure the receiver can hold the pump down. Gonna need more liquid to flood that evaporator.

Fan cycle works fine.
Omaha has pretty cold winters and we have fan cycle only systems that work with no problem.
Its an argument yes...headmaster is definitely preferred. But sometimes...thats the best option,especially with indoor units thatalready have small receivers to begin with.

What are the press of the indoor unit now?That will tell if the unit needs to be relocated.Medium temp?Suction cooled comp? No problem w/ the fan cycling control.
I put fan cycle controls for our SUMMER cold temps.Here on LI,NY we go down to 50-55*F during our summer, and I set them for 70*F +-. So I'm set for our fall,winter,spring also.

Fan cycle switch and if you want to get fancy, a headmaster valve. Fan cycling usually suffices.
